+Managing bug reports
+--------------------
+
+One of the best ways to put into practice your hacking skills is by fixing
+bugs reported by other people. Not only you will help to make the kernel
+more stable, you'll learn to fix real world problems and you will improve
+your skills, and other developers will be aware of your presence. Fixing
+bugs is one of the best ways to get merits among other developers, because
+not many people like wasting time fixing other people's bugs.
+
+To work in the already reported bug reports, go to http://bugzilla.kernel.org.
+If you want to be advised of the future bug reports, you can subscribe to the
+bugme-new mailing list (only new bug reports are mailed here) or to the
+bugme-janitor mailing list (every change in the bugzilla is mailed here)

-6. FAQ
+6. MSI quirks
+
+Several PCI chipsets or devices are known to not support MSI.
+The PCI stack provides 3 possible levels of MSI disabling:
+* on a single device
+* on all devices behind a specific bridge
+* globally
+
+6.1. Disabling MSI on a single device
+
+Under some circumstances, it might be required to disable MSI on a
+single device, It may be achived by either not calling pci_enable_msi()
+or all, or setting the pci_dev->no_msi flag before (most of the time
+in a quirk).
+
+6.2. Disabling MSI below a bridge
+
+The vast majority of MSI quirks are required by PCI bridges not
+being able to route MSI between busses. In this case, MSI have to be
+disabled on all devices behind this bridge. It is achieves by setting
+the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge
+subordinate bus. There is no need to set the same flag on bridges that
+are below the broken brigde. When pci_enable_msi() is called to enable
+MSI on a device, pci_msi_supported() takes care of checking the NO_MSI
+flag in all parent busses of the device.
+
+Some bridges actually support dynamic MSI support enabling/disabling
+by changing some bits in their PCI configuration space (especially
+the Hypertransport chipsets such as the nVidia nForce and Serverworks
+HT2000). It may then be required to update the NO_MSI flag on the
+corresponding devices in the sysfs hierarchy. To enable MSI support
+on device "0000:00:0e", do:
+
+ echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus
+
+To disable MSI support, echo 0 instead of 1. Note that it should be
+used with caution since changing this value might break interrupts.
+
+6.3. Disabling MSI globally
+
+Some extreme cases may require to disable MSI globally on the system.
+For now, the only known case is a Serverworks PCI-X chipsets (MSI are
+not supported on several busses that are not all connected to the
+chipset in the Linux PCI hierarchy). In the vast majority of other
+cases, disabling only behind a specific bridge is enough.
+
+For debugging purpose, the user may also pass pci=nomsi on the kernel
+command-line to explicitly disable MSI globally. But, once the appro-
+priate quirks are added to the kernel, this option should not be
+required anymore.
+
+6.4. Finding why MSI cannot be enabled on a device
+
+Assuming that MSI are not enabled on a device, you should look at
+dmesg to find messages that quirks may output when disabling MSI
+on some devices, some bridges or even globally.
+Then, lspci -t gives the list of bridges above a device. Reading
+/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI
+are enabled (1) or disabled (0). In 0 is found in a single bridge
+msi_bus file above the device, MSI cannot be enabled.
+
+7. FAQ
Q1. Are there any limitations on using the MSI?
disable irq on a given acquisition of that lock will result in
deadlock as soon as the RCU callback happens to interrupt that
acquisition's critical section.
+
+13. SRCU (srcu_read_lock(), srcu_read_unlock(), and synchronize_srcu())
+ may only be invoked from process context. Unlike other forms of
+ RCU, it -is- permissible to block in an SRCU read-side critical
+ section (demarked by srcu_read_lock() and srcu_read_unlock()),
+ hence the "SRCU": "sleepable RCU". Please note that if you
+ don't need to sleep in read-side critical sections, you should
+ be using RCU rather than SRCU, because RCU is almost always
+ faster and easier to use than is SRCU.
+
+ Also unlike other forms of RCU, explicit initialization
+ and cleanup is required via init_srcu_struct() and
+ cleanup_srcu_struct(). These are passed a "struct srcu_struct"
+ that defines the scope of a given SRCU domain. Once initialized,
+ the srcu_struct is passed to srcu_read_lock(), srcu_read_unlock()
+ and synchronize_srcu(). A given synchronize_srcu() waits only
+ for SRCU read-side critical sections governed by srcu_read_lock()
+ and srcu_read_unlock() calls that have been passd the same
+ srcu_struct. This property is what makes sleeping read-side
+ critical sections tolerable -- a given subsystem delays only
+ its own updates, not those of other subsystems using SRCU.
+ Therefore, SRCU is less prone to OOM the system than RCU would
+ be if RCU's read-side critical sections were permitted to
+ sleep.
+
+ The ability to sleep in read-side critical sections does not
+ come for free. First, corresponding srcu_read_lock() and
+ srcu_read_unlock() calls must be passed the same srcu_struct.
+ Second, grace-period-detection overhead is amortized only
+ over those updates sharing a given srcu_struct, rather than
+ being globally amortized as they are for other forms of RCU.
+ Therefore, SRCU should be used in preference to rw_semaphore
+ only in extremely read-intensive situations, or in situations
+ requiring SRCU's read-side deadlock immunity or low read-side
+ realtime latency.
+
+ Note that, rcu_assign_pointer() and rcu_dereference() relate to
+ SRCU just as they do to other forms of RCU.

+nfakewriters This is the number of RCU fake writer threads to run. Fake
+ writer threads repeatedly use the synchronous "wait for
+ current readers" function of the interface selected by
+ torture_type, with a delay between calls to allow for various
+ different numbers of writers running in parallel.
+ nfakewriters defaults to 4, which provides enough parallelism
+ to trigger special cases caused by multiple writers, such as
+ the synchronize_srcu() early return optimization.

as it is only incremented if a torture structure's counter
somehow gets incremented farther than it should.
+Different implementations of RCU can provide implementation-specific
+additional information. For example, SRCU provides the following:
+
+ srcu-torture: rtc: f8cf46a8 ver: 355 tfle: 0 rta: 356 rtaf: 0 rtf: 346 rtmbe: 0
+ srcu-torture: Reader Pipe: 559738 939 0 0 0 0 0 0 0 0 0
+ srcu-torture: Reader Batch: 560434 243 0 0 0 0 0 0 0 0
+ srcu-torture: Free-Block Circulation: 355 354 353 352 351 350 349 348 347 346 0
+ srcu-torture: per-CPU(idx=1): 0(0,1) 1(0,1) 2(0,0) 3(0,1)
+
+The first four lines are similar to those for RCU. The last line shows
+the per-CPU counter state. The numbers in parentheses are the values
+of the "old" and "current" counters for the corresponding CPU. The
+"idx" value maps the "old" and "current" values to the underlying array,
+and is useful for debugging.

Under each directory you would find an "online" file which is the control
file to logically online/offline a processor.
Q: Does hot-add/hot-remove refer to physical add/remove of cpus?
A: The usage of hot-add/remove may not be very consistently used in the code.
-CONFIG_CPU_HOTPLUG enables logical online/offline capability in the kernel.
+CONFIG_HOTPLUG_CPU enables logical online/offline capability in the kernel.
To support physical addition/removal, one would need some BIOS hooks and
the platform should have something like an attention button in PCI hotplug.
CONFIG_ACPI_HOTPLUG_CPU enables ACPI support for physical add/remove of CPUs.
Q: How do i logically offline a CPU?
A: Do the following.
-#echo 0 > /sys/devices/system/cpu/cpuX/online
+ #echo 0 > /sys/devices/system/cpu/cpuX/online
-once the logical offline is successful, check
+Once the logical offline is successful, check

+ #To display the current cpu state.
+ #cat /sys/devices/system/cpu/cpuX/online
Q: Why cant i remove CPU0 on some systems?
A: Some architectures may have some special dependency on a certain CPU.
departure, how to i arrange for proper notification?
A: This is what you would need in your kernel code to receive notifications.
- #include <linux/cpu.h>
- static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
+ #include <linux/cpu.h>
+ static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
unsigned long action, void *hcpu)
{
unsigned int cpu = (unsigned long)hcpu;
A: Yes, CPU notifiers are called only when new CPUs are on-lined or offlined.
If you need to perform some action for each cpu already in the system, then
- for_each_online_cpu(i) {
+ for_each_online_cpu(i) {
foobar_cpu_callback(&foobar_cpu_notifier, CPU_UP_PREPARE, i);
- foobar_cpu_callback(&foobar-cpu_notifier, CPU_ONLINE, i);

Q: If i would like to develop cpu hotplug support for a new architecture,
what do i need at a minimum?

+eCryptfs: A stacked cryptographic filesystem for Linux
+
+eCryptfs is free software. Please see the file COPYING for details.
+For documentation, please see the files in the doc/ subdirectory. For
+building and installation instructions please see the INSTALL file.
+
+Maintainer: Phillip Hellewell
+Lead developer: Michael A. Halcrow <mhalcrow@us.ibm.com>
+Developers: Michael C. Thompson
+ Kent Yoder
+Web Site: http://ecryptfs.sf.net
+
+This software is currently undergoing development. Make sure to
+maintain a backup copy of any data you write into eCryptfs.
+
+eCryptfs requires the userspace tools downloadable from the
+SourceForge site:
+
+http://sourceforge.net/projects/ecryptfs/
+
+Userspace requirements include:
+ - David Howells' userspace keyring headers and libraries (version
+ 1.0 or higher), obtainable from
+ http://people.redhat.com/~dhowells/keyutils/
+ - Libgcrypt
+
+
+NOTES
+
+In the beta/experimental releases of eCryptfs, when you upgrade
+eCryptfs, you should copy the files to an unencrypted location and
+then copy the files back into the new eCryptfs mount to migrate the
+files.
+
+
+MOUNT-WIDE PASSPHRASE
+
+Create a new directory into which eCryptfs will write its encrypted
+files (i.e., /root/crypt). Then, create the mount point directory
+(i.e., /mnt/crypt). Now it's time to mount eCryptfs:
+
+mount -t ecryptfs /root/crypt /mnt/crypt
+
+You should be prompted for a passphrase and a salt (the salt may be
+blank).
+
+Try writing a new file:
+
+echo "Hello, World" > /mnt/crypt/hello.txt
+
+The operation will complete. Notice that there is a new file in
+/root/crypt that is at least 12288 bytes in size (depending on your
+host page size). This is the encrypted underlying file for what you
+just wrote. To test reading, from start to finish, you need to clear
+the user session keyring:
+
+keyctl clear @u
+
+Then umount /mnt/crypt and mount again per the instructions given
+above.
+
+cat /mnt/crypt/hello.txt
+
+
+NOTES
+
+eCryptfs version 0.1 should only be mounted on (1) empty directories
+or (2) directories containing files only created by eCryptfs. If you
+mount a directory that has pre-existing files not created by eCryptfs,
+then behavior is undefined. Do not run eCryptfs in higher verbosity
+levels unless you are doing so for the sole purpose of debugging or
+development, since secret values will be written out to the system log
+in that case.

+Ext4 Filesystem
+===============
+
+This is a development version of the ext4 filesystem, an advanced level
+of the ext3 filesystem which incorporates scalability and reliability
+enhancements for supporting large filesystems (64 bit) in keeping with
+increasing disk capacities and state-of-the-art feature requirements.
+
+Mailing list: linux-ext4@vger.kernel.org
+
+
+1. Quick usage instructions:
+===========================
+
+ - Grab updated e2fsprogs from
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/
+ This is a patchset on top of e2fsprogs-1.39, which can be found at
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
+
+ - It's still mke2fs -j /dev/hda1
+
+ - mount /dev/hda1 /wherever -t ext4dev
+
+ - To enable extents,
+
+ mount /dev/hda1 /wherever -t ext4dev -o extents
+
+ - The filesystem is compatible with the ext3 driver until you add a file
+ which has extents (ie: `mount -o extents', then create a file).
+
+ NOTE: The "extents" mount flag is temporary. It will soon go away and
+ extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
+
+ - When comparing performance with other filesystems, remember that
+ ext3/4 by default offers higher data integrity guarantees than most. So
+ when comparing with a metadata-only journalling filesystem, use `mount -o
+ data=writeback'. And you might as well use `mount -o nobh' too along
+ with it. Making the journal larger than the mke2fs default often helps
+ performance with metadata-intensive workloads.
+
+2. Features
+===========
+
+2.1 Currently available
+
+* ability to use filesystems > 16TB
+* extent format reduces metadata overhead (RAM, IO for access, transactions)
+* extent format more robust in face of on-disk corruption due to magics,
+* internal redunancy in tree
+
+2.1 Previously available, soon to be enabled by default by "mkefs.ext4":
+
+* dir_index and resize inode will be on by default
+* large inodes will be used by default for fast EAs, nsec timestamps, etc
+
+2.2 Candidate features for future inclusion
+
+There are several under discussion, whether they all make it in is
+partly a function of how much time everyone has to work on them:
+
+* improved file allocation (multi-block alloc, delayed alloc; basically done)
+* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
+* nsec timestamps for mtime, atime, ctime, create time (patch exists,
+ needs some e2fsck work)
+* inode version field on disk (NFSv4, Lustre; prototype exists)
+* reduced mke2fs/e2fsck time via uninitialized groups (prototype exists)
+* journal checksumming for robustness, performance (prototype exists)
+* persistent file preallocation (e.g for streaming media, databases)
+
+Features like metadata checksumming have been discussed and planned for
+a bit but no patches exist yet so I'm not sure they're in the near-term
+roadmap.
+
+The big performance win will come with mballoc and delalloc. CFS has
+been using mballoc for a few years already with Lustre, and IBM + Bull
+did a lot of benchmarking on it. The reason it isn't in the first set of
+patches is partly a manageability issue, and partly because it doesn't
+directly affect the on-disk format (outside of much better allocation)
+so it isn't critical to get into the first round of changes. I believe
+Alex is working on a new set of patches right now.
+
+3. Options
+==========
+
+When mounting an ext4 filesystem, the following option are accepted:
+(*) == default
+
+extents ext4 will use extents to address file data. The
+ file system will no longer be mountable by ext3.
+
+journal=update Update the ext4 file system's journal to the current
+ format.
+
+journal=inum When a journal already exists, this option is ignored.
+ Otherwise, it specifies the number of the inode which
+ will represent the ext4 file system's journal file.
+
+journal_dev=devnum When the external journal device's major/minor numbers
+ have changed, this option allows the user to specify
+ the new journal location. The journal device is
+ identified through its new major/minor numbers encoded
+ in devnum.
+
+noload Don't load the journal on mounting.
+
+data=journal All data are committed into the journal prior to being
+ written into the main file system.
+
+data=ordered (*) All data are forced directly out to the main file
+ system prior to its metadata being committed to the
+ journal.
+
+data=writeback Data ordering is not preserved, data may be written
+ into the main file system after its metadata has been
+ committed to the journal.
+
+commit=nrsec (*) Ext4 can be told to sync all its data and metadata
+ every 'nrsec' seconds. The default value is 5 seconds.
+ This means that if you lose your power, you will lose
+ as much as the latest 5 seconds of work (your
+ filesystem will not be damaged though, thanks to the
+ journaling). This default value (or any low value)
+ will hurt performance, but it's good for data-safety.
+ Setting it to 0 will have the same effect as leaving
+ it at the default (5 seconds).
+ Setting it to very large values will improve
+ performance.
+
+barrier=1 This enables/disables barriers. barrier=0 disables
+ it, barrier=1 enables it.
+
+orlov (*) This enables the new Orlov block allocator. It is
+ enabled by default.
+
+oldalloc This disables the Orlov block allocator and enables
+ the old block allocator. Orlov should have better
+ performance - we'd like to get some feedback if it's
+ the contrary for you.
+
+user_xattr Enables Extended User Attributes. Additionally, you
+ need to have extended attribute support enabled in the
+ kernel configuration (CONFIG_EXT4_FS_XATTR). See the
+ attr(5) manual page and http://acl.bestbits.at/ to
+ learn more about extended attributes.
+
+nouser_xattr Disables Extended User Attributes.
+
+acl Enables POSIX Access Control Lists support.
+ Additionally, you need to have ACL support enabled in
+ the kernel configuration (CONFIG_EXT4_FS_POSIX_ACL).
+ See the acl(5) manual page and http://acl.bestbits.at/
+ for more information.
+
+noacl This option disables POSIX Access Control List
+ support.
+
+reservation
+
+noreservation
+
+bsddf (*) Make 'df' act like BSD.
+minixdf Make 'df' act like Minix.
+
+check=none Don't do extra checking of bitmaps on mount.
+nocheck
+
+debug Extra debugging information is sent to syslog.
+
+errors=remount-ro(*) Remount the filesystem read-only on an error.
+errors=continue Keep going on a filesystem error.
+errors=panic Panic and halt the machine if an error occurs.
+
+grpid Give objects the same group ID as their creator.
+bsdgroups
+
+nogrpid (*) New objects have the group ID of their creator.
+sysvgroups
+
+resgid=n The group ID which may use the reserved blocks.
+
+resuid=n The user ID which may use the reserved blocks.
+
+sb=n Use alternate superblock at this location.
+
+quota
+noquota
+grpquota
+usrquota
+
+bh (*) ext4 associates buffer heads to data pages to
+nobh (a) cache disk block mapping information
+ (b) link pages into transaction to provide
+ ordering guarantees.
+ "bh" option forces use of buffer heads.
+ "nobh" option tries to avoid associating buffer
+ heads (supported only for "writeback" mode).
+
+
+Data Mode
+---------
+There are 3 different data modes:
+
+* writeback mode
+In data=writeback mode, ext4 does not journal data at all. This mode provides
+a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
+mode - metadata journaling. A crash+recovery can cause incorrect data to
+appear in files which were written shortly before the crash. This mode will
+typically provide the best ext4 performance.
+
+* ordered mode
+In data=ordered mode, ext4 only officially journals metadata, but it logically
+groups metadata and data blocks into a single unit called a transaction. When
+it's time to write the new metadata out to disk, the associated data blocks
+are written first. In general, this mode performs slightly slower than
+writeback but significantly faster than journal mode.
+
+* journal mode
+data=journal mode provides full data and metadata journaling. All new data is
+written to the journal first, and then to its final location.
+In the event of a crash, the journal can be replayed, bringing both data and
+metadata into a consistent state. This mode is the slowest except when data
+needs to be read from and written to disk at the same time where it
+outperforms all others modes.

+Global File System
+------------------
+
+http://sources.redhat.com/cluster/
+
+GFS is a cluster file system. It allows a cluster of computers to
+simultaneously use a block device that is shared between them (with FC,
+iSCSI, NBD, etc). GFS reads and writes to the block device like a local
+file system, but also uses a lock module to allow the computers coordinate
+their I/O so file system consistency is maintained. One of the nifty
+features of GFS is perfect consistency -- changes made to the file system
+on one machine show up immediately on all other machines in the cluster.
+
+GFS uses interchangable inter-node locking mechanisms. Different lock
+modules can plug into GFS and each file system selects the appropriate
+lock module at mount time. Lock modules include:
+
+ lock_nolock -- allows gfs to be used as a local file system
+
+ lock_dlm -- uses a distributed lock manager (dlm) for inter-node locking
+ The dlm is found at linux/fs/dlm/
+
+In addition to interfacing with an external locking manager, a gfs lock
+module is responsible for interacting with external cluster management
+systems. Lock_dlm depends on user space cluster management systems found
+at the URL above.
+
+To use gfs as a local file system, no external clustering systems are
+needed, simply:
+
+ $ mkfs -t gfs2 -p lock_nolock -j 1 /dev/block_device
+ $ mount -t gfs2 /dev/block_device /dir
+
+GFS2 is not on-disk compatible with previous versions of GFS.

If you are compiling this driver as included in the Linux kernel
sources, simply enable the CONFIG_ACPI_IBM option (Power Management /
-ACPI / IBM ThinkPad Laptop Extras). The rest of this section describes
-how to install this driver when downloaded from the web site.
-
-First, you need to get a kernel with ACPI support up and running.
-Please refer to http://acpi.sourceforge.net/ for help with this
-step. How successful you will be depends a lot on you ThinkPad model,
-the kernel you are using and any additional patches applied. The
-kernel provided with your distribution may not be good enough. I
-needed to compile a 2.6.7 kernel with the 20040715 ACPI patch to get
-ACPI working reliably on my ThinkPad X40. Old ThinkPad models may not
-be supported at all.
-
-Assuming you have the basic ACPI support working (e.g. you can see the
-/proc/acpi directory), follow the following steps to install this
-driver:
-
- - unpack the archive:
-
- tar xzvf ibm-acpi-x.y.tar.gz; cd ibm-acpi-x.y
-
- - compile the driver:
-
- make
-
- - install the module in your kernel modules directory:
-
- make install
-
- - load the module:
-
- modprobe ibm_acpi
-
-After loading the module, check the "dmesg" output for any error messages.

-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.
+Volume control -- /proc/acpi/ibm/volume
+---------------------------------------
This feature allows volume control on ThinkPad models which don't have
a hardware volume knob. The available commands are:
echo 'level <level>' > /proc/acpi/ibm/thermal
+EXPERIMENTAL: WAN -- /proc/acpi/ibm/wan
+---------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature shows the presence and current state of a WAN (Sierra
+Wireless EV-DO) device. If WAN is installed, the following commands can
+be used:
+
+ echo enable > /proc/acpi/ibm/wan
+ echo disable > /proc/acpi/ibm/wan
+
+It was tested on a Lenovo Thinkpad X60. It should probably work on other
+Thinkpad models which come with this module installed.
Multiple Commands, Module Parameters
------------------------------------
This is the very first release of a driver for X-Box gamepads.
Basically, this was hacked away in just a few hours, so don't expect
miracles.
+
In particular, there is currently NO support for the rumble pack.
You won't find many ff-aware linux applications anyway.
-0. Status
----------
+0. Notes
+--------
+
+Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)
-For now, this driver has only been tested on just one Linux-Box.
-This one is running a 2.4.18 kernel with usb-uhci on an amd athlon 600.
+The number of buttons/axes reported varies based on 3 things:
+- if you are using a known controller
+- if you are using a known dance pad
+- if using an unknown device (one not listed below), what you set in the
+ module configuration for "Map D-PAD to buttons rather than axes for unknown
+ pads" (module option dpad_to_buttons)
-The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
-8 axes and 10 buttons.
+If you set dpad_to_buttons to 0 and you are using an unknown device (one
+not listed below), the driver will map the directional pad to axes (X/Y),
+if you said N it will map the d-pad to buttons, which is needed for dance
+style games to function correctly. The default is Y.
+
+dpad_to_buttons has no effect for known pads.
+
+0.1 Normal Controllers
+----------------------
+With a normal controller, the directional pad is mapped to its own X/Y axes.
+The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8
+axes and 10 buttons.
-Alls 8 axes work, though they all have the same range (-32768..32767)
+All 8 axes work, though they all have the same range (-32768..32767)
and the zero-setting is not correct for the triggers (I don't know if that
is some limitation of jstest, since the input device setup should be fine. I
didn't have a look at jstest itself yet).
play first person shooters with a pad. Your mileage may vary.
+0.2 Xbox Dance Pads
+-------------------
+When using a known dance pad, jstest will report 6 axes and 14 buttons.
+
+For dance style pads (like the redoctane pad) several changes
+have been made. The old driver would map the d-pad to axes, resulting
+in the driver being unable to report when the user was pressing both
+left+right or up+down, making DDR style games unplayable.
+
+Known dance pads automatically map the d-pad to buttons and will work
+correctly out of the box.
+
+If your dance pad is recognized by the driver but is using axes instead
+of buttons, see section 0.3 - Unknown Controllers
+
+I've tested this with Stepmania, and it works quite well.
+
+
+0.3 Unkown Controllers
+----------------------
+If you have an unkown xbox controller, it should work just fine with
+the default settings.
+
+HOWEVER if you have an unknown dance pad not listed below, it will not
+work UNLESS you set "dpad_to_buttons" to 1 in the module configuration.
+
+PLEASE if you have an unkown controller, email Dom <binary1230@yahoo.com> with
+a dump from /proc/bus/usb and a description of the pad (manufacturer, country,
+whether it is a dance pad or normal controller) so that we can add your pad
+to the list of supported devices, ensuring that it will work out of the
+box in the future.
+
+
1. USB adapter
--------------
Before you can actually use the driver, you need to get yourself an
-adapter cable to connect the X-Box controller to your Linux-Box.
+adapter cable to connect the X-Box controller to your Linux-Box. You
+can buy these online fairly cheap, or build your own.
-Such a cable is pretty easy to build. The Controller itself is a USB compound
-device (a hub with three ports for two expansion slots and the controller
-device) with the only difference in a nonstandard connector (5 pins vs. 4 on
-standard USB connector).

-the name, vendor and product ID, as well as the country where you bought it;
-sending the whole dump out of /proc/bus/usb/devices along would be even better).
+The driver should work with xbox pads not listed above as well, however
+you will need to do something extra for dance pads to work.
-In theory, the driver should work with other controllers than mine
-(InterAct PowerPad pro, bought in Germany) just fine, but I cannot test this
-for I only have this one controller.
+If you have a controller not listed above, see 0.3 - Unknown Controllers
If you compiled and installed the driver, test the functionality:
> modprobe xpad
> modprobe joydev
> jstest /dev/js0
-There should be a single line showing 18 inputs (8 axes, 10 buttons), and
-it's values should change if you move the sticks and push the buttons.

The function may be called enabled or disabled.
Usage Notes :
-Prior to call ccw_device_start() the device driver must assure disabled state,
-i.e. the I/O mask value in the PSW must be disabled. This can be accomplished
-by calling local_save_flags( flags). The current PSW flags are preserved and
-can be restored by local_irq_restore( flags) at a later time.
-
-If the device driver violates this rule while running in a uni-processor
-environment an interrupt might be presented prior to the ccw_device_start()
-routine returning to the device driver main path. In this case we will end in a
-deadlock situation as the interrupt handler will try to obtain the irq
-lock the device driver still owns (see below) !
-
-The driver must assure to hold the device specific lock. This can be
-accomplished by
-
-(i) spin_lock(get_ccwdev_lock(cdev)), or
-(ii) spin_lock_irqsave(get_ccwdev_lock(cdev), flags)
-
-Option (i) should be used if the calling routine is running disabled for
-I/O interrupts (see above) already. Option (ii) obtains the device gate und
-puts the CPU into I/O disabled state by preserving the current PSW flags.

- Installing and using Creative AWE midi sound under Linux.
-
-This documentation is devoted to the Creative Sound Blaster AWE32, AWE64 and
-SB32.
-
-1) Make sure you have an ORIGINAL Creative SB32, AWE32 or AWE64 card. This
- is important, because the driver works only with real Creative cards.
-
-2) The first thing you need to do is re-compile your kernel with support for
- your sound card. Run your favourite tool to configure the kernel and when
- you get to the "Sound" menu you should enable support for the following:
-
- Sound card support,
- OSS sound modules,
- 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support,
- AWE32 synth
-
- If your card is "Plug and Play" you will also need to enable these two
- options, found under the "Plug and Play configuration" menu:
-
- Plug and Play support
- ISA Plug and Play support
-
- Now compile and install the kernel in normal fashion. If you don't know
- how to do this you can find instructions for this in the README file
- located in the root directory of the kernel source.
-
-3) Before you can start playing midi files you will have to load a sound
- bank file. The utility needed for doing this is called "sfxload", and it
- is one of the utilities found in a package called "awesfx". If this
- package is not available in your distribution you can download the AWE
- snapshot from Creative Labs Open Source website:
-
- http://www.opensource.creative.com/snapshot.html
-
- Once you have unpacked the AWE snapshot you will see a "awesfx"
- directory. Follow the instructions in awesfx/docs/INSTALL to install the
- utilities in this package. After doing this, sfxload should be installed
- as:
-
- /usr/local/bin/sfxload
-
- To enable AWE general midi synthesis you should also get the sound bank
- file for general midi from:
-
- http://members.xoom.com/yar/synthgm.sbk.gz
-
- Copy it to a directory of your choice, and unpack it there.
-
-4) Edit /etc/modprobe.conf, and insert the following lines at the end of the
- file:
-
- alias sound-slot-0 sb
- alias sound-service-0-1 awe_wave
- install awe_wave /sbin/modprobe --first-time -i awe_wave && /usr/local/bin/sfxload PATH_TO_SOUND_BANK_FILE
-
- You will of course have to change "PATH_TO_SOUND_BANK_FILE" to the full
- path of the sound bank file. That will enable the Sound Blaster and AWE
- wave synthesis. To play midi files you should get one of these programs if
- you don't already have them:
-
- Playmidi: http://playmidi.openprojects.net
-
- AWEMidi Player (drvmidi) Included in the previously mentioned AWE
- snapshot.
-
- You will probably have to pass the "-e" switch to playmidi to have it use
- your midi device. drvmidi should work without switches.
-
- If something goes wrong please e-mail me. All comments and suggestions are
- welcome.

- INSTALLATION OF AWE32 SOUND DRIVER FOR LINUX
- Takashi Iwai <iwai@ww.uni-erlangen.de>
-================================================================
-
-----------------------------------------------------------------
-* Attention to SB-PnP Card Users
-
-If you're using PnP cards, the initialization of PnP is required
-before loading this driver. You have now three options:
- 1. Use isapnptools.
- 2. Use in-kernel isapnp support.
- 3. Initialize PnP on DOS/Windows, then boot linux by loadlin.
-In this document, only the case 1 case is treated.
-
-----------------------------------------------------------------
-* Installation on Red Hat 5.0 Sound Driver
-
-Please use install-rh.sh under RedHat5.0 directory.
-DO NOT USE install.sh below.
-See INSTALL.RH for more details.
-
-----------------------------------------------------------------
-* Installation/Update by Shell Script
-
- 1. Become root
-
- % su
-
- 2. If you have never configured the kernel tree yet, run make config
- once (to make dependencies and symlinks).
-
- # cd /usr/src/linux
- # make xconfig
-
- 3. Run install.sh script
-
- # sh ./install.sh
-
- 4. Configure your kernel
-
- (for Linux 2.[01].x user)
- # cd /usr/src/linux
- # make xconfig (or make menuconfig)
-
- (for Linux 1.2.x user)
- # cd /usr/src/linux
- # make config
-
- Answer YES to both "lowlevel drivers" and "AWE32 wave synth" items
- in Sound menu. ("lowlevel drivers" will appear only in 2.x
- kernel.)
-
- 5. Make your kernel (and modules), and install them as usual.
-
- 5a. make kernel image
- # make zImage
-
- 5b. make modules and install them
- # make modules && make modules_install
-
- 5c. If you're using lilo, copy the kernel image and run lilo.
- Otherwise, copy the kernel image to suitable directory or
- media for your system.
-
- 6. Reboot the kernel if necessary.
- - If you updated only the modules, you don't have to reboot
- the system. Just remove the old sound modules here.
- in
- # rmmod sound.o (linux-2.0 or OSS/Free)
- # rmmod awe_wave.o (linux-2.1)
-
- 7. If your AWE card is a PnP and not initialized yet, you'll have to
- do it by isapnp tools. Otherwise, skip to 8.
-
- This section described only a brief explanation. For more
- details, please see the AWE64-Mini-HOWTO or isapnp tools FAQ.
-
- 7a. If you have no isapnp.conf file, generate it by pnpdump.
- Otherwise, skip to 7d.
- # pnpdump > /etc/isapnp.conf
-
- 7b. Edit isapnp.conf file. Comment out the appropriate
- lines containing desirable I/O ports, DMA and IRQs.
- Don't forget to enable (ACT Y) line.
-
- 7c. Add two i/o ports (0xA20 and 0xE20) in WaveTable part.
- ex)
- (CONFIGURE CTL0048/58128 (LD 2
- # ANSI string -->WaveTable<--
- (IO 0 (BASE 0x0620))
- (IO 1 (BASE 0x0A20))
- (IO 2 (BASE 0x0E20))
- (ACT Y)
- ))
-
- 7d. Load the config file.
- CAUTION: This will reset all PnP cards!
-
- # isapnp /etc/isapnp.conf
-
- 8. Load the sound module (if you configured it as a module):
-
- for 2.0 kernel or OSS/Free monolithic module:
-
- # modprobe sound.o
-
- for 2.1 kernel:
-
- # modprobe sound
- # insmod uart401
- # insmod sb io=0x220 irq=5 dma=1 dma16=5 mpu_io=0x330
- (These values depend on your settings.)
- # insmod awe_wave
- (Be sure to load awe_wave after sb!)
-
- See Documentation/sound/oss/AWE32 for
- more details.
-
- 9. (only for obsolete systems) If you don't have /dev/sequencer
- device file, make it according to Readme.linux file on
- /usr/src/linux/drivers/sound. (Run a shell script included in
- that file). <-- This file no longer exists in the recent kernels!
-
- 10. OK, load your own soundfont file, and enjoy MIDI!
-
- % sfxload synthgm.sbk
- % drvmidi foo.mid
-
- 11. For more advanced use (eg. dynamic loading, virtual bank and
- etc.), please read the awedrv FAQ or the instructions in awesfx
- and awemidi packages.
-
-Good luck!

- An OSS/Lite Driver for the ESS Maestro family of sound cards
-
- Zach Brown, December 1999
-
-Driver Status and Availability
-------------------------------
-
-The most recent version of this driver will hopefully always be available at
- http://www.zabbo.net/maestro/
-
-I will try and maintain the most recent stable version of the driver
-in both the stable and development kernel lines.
-
-ESS Maestro Chip Family
------------------------
-
-There are 3 main variants of the ESS Maestro PCI sound chip. The first
-is the Maestro 1. It was originally produced by Platform Tech as the
-'AGOGO'. It can be recognized by Platform Tech's PCI ID 0x1285 with
-0x0100 as the device ID. It was put on some sound boards and a few laptops.
-ESS bought the design and cleaned it up as the Maestro 2. This starts
-their marking with the ESS vendor ID 0x125D and the 'year' device IDs.
-The Maestro 2 claims 0x1968 while the Maestro 2e has 0x1978.
-
-The various families of Maestro are mostly identical as far as this
-driver is concerned. It doesn't touch the DSP parts that differ (though
-it could for FM synthesis).
-
-Driver OSS Behavior
---------------------
-
-This OSS driver exports /dev/mixer and /dev/dsp to applications, which
-mostly adhere to the OSS spec. This driver doesn't register itself
-with /dev/sndstat, so don't expect information to appear there.
-
-The /dev/dsp device exported behaves almost as expected. Playback is
-supported in all the various lovely formats. 8/16bit stereo/mono from
-8khz to 48khz, and mmap()ing for playback behaves. Capture/recording
-is limited due to oddities with the Maestro hardware. One can only
-record in 16bit stereo. For recording the maestro uses non interleaved
-stereo buffers so that mmap()ing the incoming data does not result in
-a ring buffer of LRLR data. mmap()ing of the read buffers is therefore
-disallowed until this can be cleaned up.
-
-/dev/mixer is an interface to the AC'97 codec on the Maestro. It is
-worth noting that there are a variety of AC'97s that can be wired to
-the Maestro. Which is used is entirely up to the hardware implementor.
-This should only be visible to the user by the presence, or lack, of
-'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them.
-
-The driver doesn't support MIDI or FM playback at the moment. Typically
-the Maestro is wired to an MPU MIDI chip, but some hardware implementations
-don't. We need to assemble a white list of hardware implementations that
-have MIDI wired properly before we can claim to support it safely.
-
-Compiling and Installing
-------------------------
-
-With the drivers inclusion into the kernel, compiling and installing
-is the same as most OSS/Lite modular sound drivers. Compilation
-of the driver is enabled through the CONFIG_SOUND_MAESTRO variable
-in the config system.
-
-It may be modular or statically linked. If it is modular it should be
-installed with the rest of the modules for the kernel on the system.
-Typically this will be in /lib/modules/ somewhere. 'alias sound maestro'
-should also be added to your module configs (typically /etc/conf.modules)
-if you're using modular OSS/Lite sound and want to default to using a
-maestro chip.
-
-As this is a PCI device, the module does not need to be informed of
-any IO or IRQ resources it should use, it devines these from the
-system. Sometimes, on sucky PCs, the BIOS fails to allocated resources
-for the maestro. This will result in a message like:
- maestro: PCI subsystem reports IRQ 0, this might not be correct.
-from the kernel. Should this happen the sound chip most likely will
-not operate correctly. To solve this one has to dig through their BIOS
-(typically entered by hitting a hot key at boot time) and figure out
-what magic needs to happen so that the BIOS will reward the maestro with
-an IRQ. This operation is incredibly system specific, so you're on your
-own. Sometimes the magic lies in 'PNP Capable Operating System' settings.
-
-There are very few options to the driver. One is 'debug' which will
-tell the driver to print minimal debugging information as it runs. This
-can be collected with 'dmesg' or through the klogd daemon.
-
-The other, more interesting option, is 'dsps_order'. Typically at
-install time the driver will only register one available /dev/dsp device
-for its use. The 'dsps_order' module parameter allows for more devices
-to be allocated, as a power of two. Up to 4 devices can be registered
-( dsps_order=2 ). These devices act as fully distinct units and use
-separate channels in the maestro.
-
-Power Management
-----------------
-
-As of version 0.14, this driver has a minimal understanding of PCI
-Power Management. If it finds a valid power management capability
-on the PCI device it will attempt to use the power management
-functions of the maestro. It will only do this on Maestro 2Es and
-only on machines that are known to function well. You can
-force the use of power management by setting the 'use_pm' module
-option to 1, or can disable it entirely by setting it to 0.
-
-When using power management, the driver does a few things
-differently. It will keep the chip in a lower power mode
-when the module is inserted but /dev/dsp is not open. This
-allows the mixer to function but turns off the clocks
-on other parts of the chip. When /dev/dsp is opened the chip
-is brought into full power mode, and brought back down
-when it is closed. It also powers down the chip entirely
-when the module is removed or the machine is shutdown. This
-can have nonobvious consequences. CD audio may not work
-after a power managing driver is removed. Also, software that
-doesn't understand power management may not be able to talk
-to the powered down chip until the machine goes through a hard
-reboot to bring it back.

- An OSS/Lite Driver for the ESS Maestro3 family of sound chips
-
- Zach Brown, January 2001
-
-Driver Status and Availability
-------------------------------
-
-The most recent version of this driver will hopefully always be available at
- http://www.zabbo.net/maestro3/
-
-I will try and maintain the most recent stable version of the driver
-in both the stable and development kernel lines.
-
-Historically I've sucked pretty hard at actually doing that, however.
-
-ESS Maestro3 Chip Family
------------------------
-
-The 'Maestro3' is much like the Maestro2 chip. The noted improvement
-is the removal of the silicon in the '2' that did PCM mixing. All that
-work is now done through a custom DSP called the ASSP, the Asynchronus
-Specific Signal Processor.
-
-The 'Allegro' is a baby version of the Maestro3. I'm not entirely clear
-on the extent of the differences, but the driver supports them both :)
-
-The 'Allegro' shows up as PCI ID 0x1988 and the Maestro3 as 0x1998,
-both under ESS's vendor ID of 0x125D. The Maestro3 can also show up as
-0x199a when hardware strapping is used.
-
-The chip can also act as a multi function device. The modem IDs follow
-the audio multimedia device IDs. (so the modem part of an Allegro shows
-up as 0x1989)
-
-Driver OSS Behavior
---------------------
-
-This OSS driver exports /dev/mixer and /dev/dsp to applications, which
-mostly adhere to the OSS spec. This driver doesn't register itself
-with /dev/sndstat, so don't expect information to appear there.
-
-The /dev/dsp device exported behaves as expected. Playback is
-supported in all the various lovely formats. 8/16bit stereo/mono from
-8khz to 48khz, with both read()/write(), and mmap().
-
-/dev/mixer is an interface to the AC'97 codec on the Maestro3. It is
-worth noting that there are a variety of AC'97s that can be wired to
-the Maestro3. Which is used is entirely up to the hardware implementor.
-This should only be visible to the user by the presence, or lack, of
-'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them.
-The Allegro has an onchip AC'97.
-
-The driver doesn't support MIDI or FM playback at the moment.
-
-Compiling and Installing
-------------------------
-
-With the drivers inclusion into the kernel, compiling and installing
-is the same as most OSS/Lite modular sound drivers. Compilation
-of the driver is enabled through the CONFIG_SOUND_MAESTRO3 variable
-in the config system.
-
-It may be modular or statically linked. If it is modular it should be
-installed with the rest of the modules for the kernel on the system.
-Typically this will be in /lib/modules/ somewhere. 'alias sound-slot-0
-maestro3' should also be added to your module configs (typically
-/etc/modprobe.conf) if you're using modular OSS/Lite sound and want to
-default to using a maestro3 chip.
-
-There are very few options to the driver. One is 'debug' which will
-tell the driver to print minimal debugging information as it runs. This
-can be collected with 'dmesg' or through the klogd daemon.
-
-One is 'external_amp', which tells the driver to attempt to enable
-an external amplifier. This defaults to '1', you can tell the driver
-not to bother enabling such an amplifier by setting it to '0'.
-
-And the last is 'gpio_pin', which tells the driver which GPIO pin number
-the external amp uses (0-15), The Allegro uses 8 by default, all others 1.
-If everything loads correctly and seems to be working but you get no sound,
-try tweaking this value.
-
-Systems known to need a different value
- Panasonic ToughBook CF-72: gpio_pin=13
-
-Power Management
-----------------
-
-This driver has a minimal understanding of PCI Power Management. It will
-try and power down the chip when the system is suspended, and power
-it up with it is resumed. It will also try and power down the chip
-when the machine is shut down.

-Linux 2.4 Sound Changes
-2000-September-25
-Christoph Hellwig, <hch@infradead.org>
-
-
-
-=== isapnp support
-
-The Linux 2.4 Kernel does have reliable in-kernel isapnp support.
-Some drivers (sb.o, ad1816.o awe_wave.o) do now support automatically
-detecting and configuring isapnp devices.
-If you have a not yet supported isapnp soundcard, mail me the content
-of '/proc/isapnp' on your system and some information about your card
-and its driver(s) so I can try to get isapnp working for it.
-
-
-
-=== soundcard resources on kernel commandline
-
-Before Linux 2.4 you had to specify the resources for sounddrivers
-statically linked into the kernel at compile time
-(in make config/menuconfig/xconfig). In Linux 2.4 the resources are
-now specified at the boot-time kernel commandline (e.g. the lilo
-'append=' line or everything that's after the kernel name in grub).
-Read the Configure.help entry for your card for the parameters.
-
-
-=== softoss is gone
-
-In Linux 2.4 the softoss in-kernel software synthesizer is no more aviable.
-Use a user space software synthesizer like timidity instead.
-
-
-
-=== /dev/sndstat and /proc/sound are gone
-
-In older Linux versions those files exported some information about the
-OSS/Free configuration to userspace. In Linux 2.3 they were removed because
-they did not support the growing number of pci soundcards and there were
-some general problems with this interface.
-
-
+++ /dev/null
-OPL3-SA1 sound driver (opl3sa.o)
-
----
-Note: This howto only describes how to setup the OPL3-SA1 chip; this info
-does not apply to the SA2, SA3, or SA4.
----
-
-The Yamaha OPL3-SA1 sound chip is usually found built into motherboards, and
-it's a decent little chip offering a WSS mode, a SB Pro emulation mode, MPU401
-and OPL3 FM Synth capabilities.
-
-You can enable inclusion of the driver via CONFIG_SOUND_OPL3SA1=m, or
-CONFIG_SOUND_OPL3SA1=y through 'make config/xconfig/menuconfig'.
-
-You'll need to know all of the relevant info (irq, dma, and io port) for the
-chip's WSS mode, since that is the mode the kernel sound driver uses, and of
-course you'll also need to know about where the MPU401 and OPL3 ports and
-IRQs are if you want to use those.
-
-Here's the skinny on how to load it as a module:
-
- modprobe opl3sa io=0x530 irq=11 dma=0 dma2=1 mpu_io=0x330 mpu_irq=5
-
-Module options in detail:
-
- io: This is the WSS's port base.
- irq: This is the WSS's IRQ.
- dma: This is the WSS's DMA line. In my BIOS setup screen this was
- listed as "WSS Play DMA"
- dma2: This is the WSS's secondary DMA line. My BIOS calls it the
- "WSS capture DMA"
-
- mpu_io: This is the MPU401's port base.
- mpu_irq: This is the MPU401's IRQ.
-
-If you'd like to use the OPL3 FM Synthesizer, make sure you enable
-CONFIG_SOUND_YM3812 (in 'make config'). That'll build the opl3.o module.
-
-Then a simple 'insmod opl3 io=0x388', and you now have FM Synth.
-
-You can also use the SoftOSS software synthesizer instead of the builtin OPL3.
-Here's how:
-
-Say 'y' or 'm' to "SoftOSS software wave table engine" in make config.
-
-If you said yes, the software synth is available once you boot your new
-kernel.
-
-If you chose to build it as a module, just insmod the resulting softoss2.o

-================================================================
- AWE32 Sound Driver for Linux / FreeBSD
- version 0.4.3; Nov. 1, 1998
-
- Takashi Iwai <iwai@ww.uni-erlangen.de>
-================================================================
-
-* GENERAL NOTES
-
-This is a sound driver extension for SoundBlaster AWE32 and other
-compatible cards (AWE32-PnP, SB32, SB32-PnP, AWE64 & etc) to enable
-the wave synth operations. The driver is provided for Linux 1.2.x
-and 2.[012].x kernels, as well as FreeBSD, on Intel x86 and DEC
-Alpha systems.
-
-This driver was written by Takashi Iwai <iwai@ww.uni-erlangen.de>,
-and provided "as is". The original source (awedrv-0.4.3.tar.gz) and
-binary packages are available on the following URL:
- http://bahamut.mm.t.u-tokyo.ac.jp/~iwai/awedrv/
-Note that since the author is apart from this web site, the update is
-not frequent now.
-
-
-* NOTE TO LINUX USERS
-
-To enable this driver on linux-2.[01].x kernels, you need turn on
-"AWE32 synth" options in sound menu when configure your linux kernel
-and modules. The precise installation procedure is described in the
-AWE64-Mini-HOWTO and linux-kernel/Documetation/sound/AWE32.
-
-If you're using PnP cards, the card must be initialized before loading
-the sound driver. There're several options to do this:
- - Initialize the card via ISA PnP tools, and load the sound module.
- - Initialize the card on DOS, and load linux by loadlin.exe
- - Use PnP kernel driver (for Linux-2.x.x)
-The detailed instruction for the solution using isapnp tools is found
-in many documents like above. A brief instruction is also included in
-the installation document of this package.
-For PnP driver project, please refer to the following URL:
- http://www-jcr.lmh.ox.ac.uk/~pnp/
-
-
-* USING THE DRIVER
-
-The awedrv has several different playing modes to realize easy channel
-allocation for MIDI songs. To hear the exact sound quality, you need
-to obtain the extended sequencer program, drvmidi or playmidi-2.5.
-
-For playing MIDI files, you *MUST* load the soundfont file on the
-driver previously by sfxload utility. Otherwise you'll here no sounds
-at all! All the utilities and driver source packages are found in the
-above URL. The sfxload program is included in the package
-awesfx-0.4.3.tgz. Binary packages are available there, too. See the
-instruction in each package for installation.
-
-Loading a soundfont file is very simple. Just execute the command
-
- % sfxload synthgm.sbk
-
-Then, sfxload transfers the file "synthgm.sbk" to the driver.
-Both SF1 and SF2 formats are accepted.
-
-Now you can hear midi musics by a midi player.
-
- % drvmidi foo.mid
-
-If you run MIDI player after MOD player, you need to load soundfont
-files again, since MOD player programs clear the previous loaded
-samples by their own data.
-
-If you have only 512kb on the sound card, I recommend to use dynamic
-sample loading via -L option of drvmidi. 2MB GM/GS soundfont file is
-available in most midi files.
-
- % sfxload synthgm
- % drvmidi -L 2mbgmgs foo.mid
-
-This makes a big difference (believe me)! For more details, please
-refer to the FAQ list which is available on the URL above.
-
-The current chorus, reverb and equalizer status can be changed by
-aweset utility program (included in awesfx package). Note that
-some awedrv-native programs (like drvmidi and xmp) will change the
-current settings by themselves. The aweset program is effective
-only for other programs like playmidi.
-
-Enjoy.
-
-
-* COMPILE FLAGS
-
-Compile conditions are defined in awe_config.h.
-
-[Compatibility Conditions]
-The following flags are defined automatically when using installation
-shell script.
-
-- AWE_MODULE_SUPPORT
- indicates your Linux kernel supports module for each sound card
- (in recent 2.1 or 2.2 kernels and unofficial patched 2.0 kernels
- as distributed in the RH5.0 package).
- This flag is automatically set when you're using 2.1.x kernels.
- You can pass the base address and memory size via the following
- module options,
- io = base I/O port address (eg. 0x620)
- memsize = DRAM size in kilobytes (eg. 512)
- As default, AWE driver probes these values automatically.
-
-
-[Hardware Conditions]
-You DON'T have to define the following two values.
-Define them only when the driver couldn't detect the card properly.
-
-- AWE_DEFAULT_BASE_ADDR (default: not defined)
- specifies the base port address of your AWE32 card.
- 0 means to autodetect the address.
-
-- AWE_DEFAULT_MEM_SIZE (default: not defined)
- specifies the memory size of your AWE32 card in kilobytes.
- -1 means to autodetect its size.
-
-
-[Sample Table Size]
-From ver.0.4.0, sample tables are allocated dynamically (except
-Linux-1.2.x system), so you need NOT to touch these parameters.
-Linux-1.2.x users may need to increase these values to appropriate size
-if the sound card is equipped with more DRAM.
-
-- AWE_MAX_SF_LISTS, AWE_MAX_SAMPLES, AWE_MAX_INFOS
-
-
-[Other Conditions]
-
-- AWE_ALWAYS_INIT_FM (default: not defined)
- indicates the AWE driver always initialize FM passthrough even
- without DRAM on board. Emu8000 chip has a restriction for playing
- samples on DRAM that at least two channels must be occupied as
- passthrough channels.
-
-- AWE_DEBUG_ON (default: defined)
- turns on debugging messages if defined.
-
-- AWE_HAS_GUS_COMPATIBILITY (default: defined)
- Enables GUS compatibility mode if defined, reading GUS patches and
- GUS control commands. Define this option to use GMOD or other
- GUS module players.
-
-- CONFIG_AWE32_MIDIEMU (default: defined)
- Adds a MIDI emulation device by Emu8000 wavetable. The emulation
- device can be accessed as an external MIDI, and sends the MIDI
- control codes directly. XG and GS sysex/NRPN are accepted.
- No MIDI input is supported.
-
-- CONFIG_AWE32_MIXER (default: not defined)
- Adds a mixer device for AWE32 bass/treble equalizer control.
- You can access this device using /dev/mixer?? (usually mixer01).
-
-- AWE_USE_NEW_VOLUME_CALC (default: defined)
- Use the new method to calculate the volume change as compatible
- with DOS/Win drivers. This option can be toggled via aweset
- program, or drvmidi player.
-
-- AWE_CHECK_VTARGET (default: defined)
- Check the current volume target value when searching for an
- empty channel to allocate a new voice. This is experimentally
- implemented in this version. (probably, this option doesn't
- affect the sound quality severely...)
-
-- AWE_ALLOW_SAMPLE_SHARING (default: defined)
- Allow sample sharing for differently loaded patches.
- This function is available only together with awesfx-0.4.3p3.
- Note that this is still an experimental option.
-
-- DEF_FM_CHORUS_DEPTH (default: 0x10)
- The default strength to be sent to the chorus effect engine.
- From 0 to 0xff. Larger numbers may often cause weird sounds.
-
-- DEF_FM_REVERB_DEPTH (default: 0x10)
- The default strength to be sent to the reverb effect engine.
- From 0 to 0xff. Larger numbers may often cause weird sounds.
-
-

- An OSS/Free Driver for WaveFront soundcards
- (Turtle Beach Maui, Tropez, Tropez Plus)
-
- Paul Barton-Davis, July 1998
-
- VERSION 0.2.5
-
-Driver Status
--------------
-
-Requires: Kernel 2.1.106 or later (the driver is included with kernels
-2.1.109 and above)
-
-As of 7/22/1998, this driver is currently in *BETA* state. This means
-that it compiles and runs, and that I use it on my system (Linux
-2.1.106) with some reasonably demanding applications and uses. I
-believe the code is approaching an initial "finished" state that
-provides bug-free support for the Tropez Plus.
-
-Please note that to date, the driver has ONLY been tested on a Tropez
-Plus. I would very much like to hear (and help out) people with Tropez
-and Maui cards, since I think the driver can support those cards as
-well.
-
-Finally, the driver has not been tested (or even compiled) as a static
-(non-modular) part of the kernel. Alan Cox's good work in modularizing
-OSS/Free for Linux makes this rather unnecessary.
-
-Some Questions
---------------
-
-**********************************************************************
-0) What does this driver do that the maui driver did not ?
-**********************************************************************
-
-* can fully initialize a WaveFront card from cold boot - no DOS
- utilities needed
-* working patch/sample/program loading and unloading (the maui
- driver didn't document how to make this work, and assumed
- user-level preparation of the patch data for writing
- to the board. ick.)
-* full user-level access to all WaveFront commands
-* for the Tropez Plus, (primitive) control of the YSS225 FX processor
-* Virtual MIDI mode supported - 2 MIDI devices accessible via the
- WaveFront's MPU401/UART emulation. One
- accesses the WaveFront synth, the other accesses the
- external MIDI connector. Full MIDI read/write semantics
- for both devices.
-* OSS-compliant /dev/sequencer interface for the WaveFront synth,
- including native and GUS-format patch downloading.
-* semi-intelligent patch management (prototypical at this point)
-
-**********************************************************************
-1) What to do about MIDI interfaces ?
-**********************************************************************
-
-The Tropez Plus (and perhaps other WF cards) can in theory support up
-to 2 physical MIDI interfaces. One of these is connected to the
-ICS2115 chip (the WaveFront synth itself) and is controlled by
-MPU/UART-401 emulation code running as part of the WaveFront OS. The
-other is controlled by the CS4232 chip present on the board. However,
-physical access to the CS4232 connector is difficult, and it is
-unlikely (though not impossible) that you will want to use it.
-
-An older version of this driver introduced an additional kernel config
-variable which controlled whether or not the CS4232 MIDI interface was
-configured. Because of Alan Cox's work on modularizing the sound
-drivers, and now backporting them to 2.0.34 kernels, there seems to be
-little reason to support "static" configuration variables, and so this
-has been abandoned in favor of *only* module parameters. Specifying
-"mpuio" and "mpuirq" for the cs4232 parameter will result in the
-CS4232 MIDI interface being configured; leaving them unspecified will
-leave it unconfigured (and thus unusable).
-
-BTW, I have heard from one Tropez+ user that the CS4232 interface is
-more reliable than the ICS2115 one. I have had no problems with the
-latter, and I don't have the right cable to test the former one
-out. Reports welcome.

-**********************************************************************
-2) Why does line XXX of the code look like this .... ?
-**********************************************************************
-
-Either because it's not finished yet, or because you're a better coder
-than I am, or because you don't understand some aspect of how the card
-or the code works.
-
-I absolutely welcome comments, criticisms and suggestions about the
-design and implementation of the driver.
-
-**********************************************************************
-3) What files are included ?
-**********************************************************************
-
- drivers/sound/README.wavefront -- this file
-
- drivers/sound/wavefront.patch -- patches for the 2.1.106 sound drivers
- needed to make the rest of this work
- DO NOT USE IF YOU'VE APPLIED THEM
- BEFORE, OR HAVE 2.1.109 OR ABOVE

-4) How do I compile/install/use it ?
-**********************************************************************
-
-PART ONE: install the source code into your sound driver directory

- AND HAVE NOT ALREADY INSTALLED THE PATCH(ES).
-
- cd drivers/sound
- patch < wavefront.patch
-
-PART THREE: configure your kernel
-
- cd <top of your kernel tree>
- make xconfig (or whichever config option you use)
-
- - choose YES for Sound Support
- - choose MODULE (M) for OSS Sound Modules
- - choose MODULE(M) to YM3812/OPL3 support
- - choose MODULE(M) for WaveFront support
- - choose MODULE(M) for CS4232 support
-
- - choose "N" for everything else (unless you have other
- soundcards you want support for)
-
-
- make boot
- .
- .

-************************************************************
-6) How do I configure my card ?
-************************************************************
-
-You need to edit /etc/modprobe.conf. Here's mine (edited to show the
-relevant details):
-
- # Sound system
- alias char-major-14-* wavefront
- alias synth0 wavefront
- alias mixer0 cs4232
- alias audio0 cs4232
- install wavefront /sbin/modprobe cs4232 && /sbin/modprobe -i wavefront && /sbin/modprobe opl3
- options wavefront io=0x200 irq=9
- options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
- options opl3 io=0x388
-
-Things to note:
-
- the wavefront options "io" and "irq" ***MUST*** match the "synthio"
- and "synthirq" cs4232 options.
-
- you can do without the opl3 module if you don't
- want to use the OPL/[34] FM synth on the soundcard
-
- the opl3 io parameter is conventionally not adjustable.
- In theory, any not-in-use IO port address would work, but
- just use 0x388 and stick with the crowd.
-
-**********************************************************************
-7) What about firmware ?
-**********************************************************************
-
-Turtle Beach have not given me permission to distribute their firmware
-for the ICS2115. However, if you have a WaveFront card, then you
-almost certainly have the firmware, and if not, its freely available
-on their website, at:
-
- http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus
-
-The file is called WFOS2001.MOT (for the Tropez+).
-
-This driver, however, doesn't use the pure firmware as distributed,
-but instead relies on a somewhat processed form of it. You can
-generate this very easily. Following an idea from Andrew Veliath's
-Pinnacle driver, the following flex program will generate the
-processed version:
-
----- cut here -------------------------
-%option main
-%%
-^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext);
-<<EOF>> { fputc ('\0', stdout); return; }
-\n {}
-. {}
----- cut here -------------------------
-
-To use it, put the above in file (say, ws.l) compile it like this:
-
- shell> flex -ows.c ws.l
- shell> cc -o ws ws.c
-
-and then use it like this:
-
- ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os
-
-If you put it somewhere else, you'll always have to use the wf_ospath
-module parameter (see below) or alter the source code.
-
-**********************************************************************
-7) How do I get it working ?
-**********************************************************************
-
-Optionally, you can reboot with the "new" kernel (even though the only
-changes have really been made to a module).
-
-Then, as root do:
-
- modprobe wavefront
-
-You should get something like this in /var/log/messages:
-
- WaveFront: firmware 1.20 already loaded.
-
-or
-
- WaveFront: no response to firmware probe, assume raw.
-
-then:
-
- WaveFront: waiting for memory configuration ...
- WaveFront: hardware version 1.64
- WaveFront: available DRAM 8191k
- WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty
- WaveFront: 128 programs slots in use
- WaveFront: 256 patch slots filled, 142 in use
-
-The whole process takes about 16 seconds, the longest waits being
-after reporting the hardware version (during the firmware download),
-and after reporting program status (during patch status inquiry). Its
-shorter (about 10 secs) if the firmware is already loaded (i.e. only
-warm reboots since the last firmware load).
-
-The "available DRAM" line will vary depending on how much added RAM
-your card has. Mine has 8MB.
-
-To check basically functionality, use play(1) or splay(1) to send a
-.WAV or other audio file through the audio portion. Then use playmidi
-to play a General MIDI file. Try the "-D 0" to hear the
-difference between sending MIDI to the WaveFront and using the OPL/3,
-which is the default (I think ...). If you have an external synth(s)
-hooked to the soundcard, you can use "-e" to route to the
-external synth(s) (in theory, -D 1 should work as well, but I think
-there is a bug in playmidi which prevents this from doing what it
-should).
-
-**********************************************************************
-8) What are the module parameters ?
-**********************************************************************
-
-Its best to read wavefront.c for this, but here is a summary:
-
-integers:
- wf_raw - if set, ignore apparent presence of firmware
- loaded onto the ICS2115, reset the whole
- board, and initialize it from scratch. (default = 0)
-
- fx_raw - if set, always initialize the YSS225 processor
- on the Tropez plus. (default = 1)
-
- < The next 4 are basically for kernel hackers to allow
- tweaking the driver for testing purposes. >
-
- wait_usecs - loop timer used when waiting for
- status conditions on the board.
- The default is 150.
-
- debug_default - debugging flags. See sound/wavefront.h
- for WF_DEBUG_* values. Default is zero.
- Setting this allows you to debug the
- driver during module installation.
-strings:
- ospath - path to get to the pre-processed OS firmware.
- (default: /etc/sound/wavefront.os)
-
-**********************************************************************
-9) Who should I contact if I have problems?
-**********************************************************************
-
-Just me: Paul Barton-Davis <pbd@op.net>

-
+++ /dev/null
-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-This soundcard does not have any hardware MIDI synthesizer;
-MIDI synthesis has to be done in software. To allow this
-the driver/soundcard supports two PCM (/dev/dsp) interfaces.
-The second one goes to the mixer "synth" setting and supports
-only a limited set of sampling rates (44100, 22050, 11025, 5512).
-By setting lineout to 1 on the driver command line
-(eg. insmod es1370 lineout=1) it is even possible on some
-cards to convert the LINEIN jack into a second LINEOUT jack, thus
-making it possible to output four independent audio channels!
-
-There is a freely available software package that allows
-MIDI file playback on this soundcard called Timidity.
-See http://www.cgs.fi/~tt/timidity/.

-Beta release of the rme96xx (driver for RME 96XX cards like the
-"Hammerfall" and the "Hammerfall light")
-
-Important: The driver module has to be installed on a freshly rebooted system,
-otherwise the driver might not be able to acquire its buffers.
-
-features:
-
- - OSS programming interface (i.e. runs with standard OSS soundsoftware)
- - OSS/Multichannel interface (OSS multichannel is done by just aquiring
- more than 2 channels). The driver does not use more than one device
- ( yet .. this feature may be implemented later )
- - more than one RME card supported
-
-The driver uses a specific multichannel interface, which I will document
-when the driver gets stable. (take a look at the defines in rme96xx.h,
-which adds blocked multichannel formats i.e instead of
-lrlrlrlr --> llllrrrr etc.
-
-Use the "rmectrl" programm to look at the status of the card ..
-or use xrmectrl, a GUI interface for the ctrl program.
-
-What you can do with the rmectrl program is to set the stereo device for
-OSS emulation (e.g. if you use SPDIF out).
-
-You do:
-
-./ctrl offset 24 24
-
-which makes the stereo device use channels 25 and 26.
-
-Guenter Geiger <geiger@epy.co.at>
-
-copy the first part of the attached source code into rmectrl.c
-and the second part into xrmectrl (or get the program from
-http://gige.xdv.org/pages/soft/pages/rme)
-
-to compile: gcc -o rmectrl rmectrl.c

-Recording
----------
-
-Recording does not work on the author's card, but there
-is at least one report of it working on later silicon.
-The chip behaves differently than described in the data sheet,
-likely due to a chip bug. Working around this would require
-the help of ESS (for example by publishing an errata sheet),
-but ESS has not done so far.
-
-Also, the chip only supports 24 bit addresses for recording,
-which means it cannot work on some Alpha mainboards.
-
-
-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (or later, available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-The card has an OPL compatible FM synthesizer.

----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-The card both has an OPL compatible FM synthesizer as well as
-a wavetable synthesizer.
-
-I haven't managed so far to get the OPL synth running.
-
-Using the wavetable synthesizer requires allocating
-1-4MB of physically contiguous memory, which isn't possible
-currently on Linux without ugly hacks like the bigphysarea
-patch. Therefore, the driver doesn't support wavetable
-synthesis.
-
-
-No support from S3
-------------------
-
-I do not get any support from S3. Therefore, the driver
-still has many problems. For example, although the manual
-states that the chip should be able to access the sample
-buffer anywhere in 32bit address space, I haven't managed to
-get it working with buffers above 16M. Therefore, the card
-has the same disadvantages as ISA soundcards.
-
-Given that the card is also very noisy, and if you haven't
-already bought it, you should strongly opt for one of the
-comparatively priced Ensoniq products.

core_pattern:
core_pattern is used to specify a core dumpfile pattern name.
-. max length 64 characters; default value is "core"
+. max length 128 characters; default value is "core"
. core_pattern is used as a pattern template for the output filename;
certain string patterns (beginning with '%') are substituted with
their actual values.
%h hostname
%e executable filename
%<OTHER> both are dropped
+. If the first character of the pattern is a '|', the kernel will treat
+ the rest of the pattern as a command to run. The core dump will be
+ written to the standard input of that program instead of to a file.

+ This option 'selects' (turns on, enables) 'TIFM_CORE', but you

*
* Changed full name of USB-UIRT device to avoid "/" character.

* Added PID for "ELV USB Module UO100" from Stefan Frings.

* that we have proper reference counting logic for urbs. I nicked this
* from Greg KH's Visor driver.
- *
+ *
* (23/Jun/2003) Ian Abbott
* Reduced flip buffer pushes and corrected a data length test in
* ftdi_read_bulk_callback.
*
* (21/Jun/2003) Erik Nygren
* Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
- * See <http://www.home-electro.com/tira1.htm>. Only operates properly
+ * See <http://www.home-electro.com/tira1.htm>. Only operates properly
* at 100000 and RTS-CTS, so set custom divisor mode on startup.
* Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
*
* (17/Feb/2003) Bill Ryder
* Added write urb buffer pool on a per device basis
* Added more checking for open file on callbacks (fixed OOPS)
- * Added CrystalFontz 632 and 634 PIDs
+ * Added CrystalFontz 632 and 634 PIDs
* (thanx to CrystalFontz for the sample devices - they flushed out

* Minor debugging message changes
* Added throttle, unthrottle and chars_in_buffer functions
* Fixed FTDI_SIO (the original device) bug
* Fixed some shutdown handling
- *
- *
- *

* (07/Jun/2002) Kuba Ober
* Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
* function. It was getting too complex.
*
* (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
* Not tested by me but it doesn't break anything I use.
- *
+ *
* (04/Jan/2002) Kuba Ober
* Implemented 38400 baudrate kludge, where it can be substituted with other
* values. That's the only way to set custom baudrates.
* (the previous version caused panics)
* Removed port iteration code since the device only has one I/O port and it
* was wrong anyway.
- *
+ *
* (31/May/2001) gkh
* Switched from using spinlock to a semaphore, which fixes lots of problems.
*
* Cleaned up comments for 8U232
* Added parity, framing and overrun error handling
* Added receive break handling.
- *
+ *
* (04/08/2001) gb
* Identify version on module load.
- *
+ *
* (18/March/2001) Bill Ryder
* (Not released)
* Added send break handling. (requires kernel patch too)
* Fixed 8U232AM hardware RTS/CTS etc status reporting.
* Added flipbuf fix copied from generic device
- *
+ *
* (12/3/2000) Bill Ryder
* Added support for 8U232AM device.
* Moved PID and VIDs into header file only.
* Cleaned up comments. Removed multiple PID/VID definitions.
* Factorised cts/dtr code
* Made use of __FUNCTION__ in dbg's
- *
+ *
* (11/01/2000) Adam J. Richter

+ help
+ Ext4dev is a predecessor filesystem of the next generation
+ extended fs ext4, based on ext3 filesystem code. It will be
+ renamed ext4 fs later, once ext4dev is mature and stabilized.
+
+ Unlike the change from ext2 filesystem to ext3 filesystem,
+ the on-disk format of ext4dev is not the same as ext3 any more:
+ it is based on extent maps and it supports 48-bit physical block
+ numbers. These combined on-disk format changes will allow
+ ext4dev/ext4 to handle more than 16 TB filesystem volumes --
+ a hard limit that ext3 cannot overcome without changing the
+ on-disk format.
+
+ Other than extent maps and 48-bit block numbers, ext4dev also is
+ likely to have other new features such as persistent preallocation,
+ high resolution time stamps, and larger file support etc. These
+ features will be added to ext4dev gradually.
+
+ To compile this file system support as a module, choose M here. The
+ module will be called ext4dev. Be aware, however, that the filesystem
+ of your root partition (the one containing the directory /) cannot
+ be compiled as a module, and so this could be dangerous.
+
+ If unsure, say N.

+/* Central locking logic has four stages:
+
+ dlm_lock()
+ dlm_unlock()
+
+ request_lock(ls, lkb)
+ convert_lock(ls, lkb)
+ unlock_lock(ls, lkb)
+ cancel_lock(ls, lkb)
+
+ _request_lock(r, lkb)
+ _convert_lock(r, lkb)

+ _cancel_lock(r, lkb)
+
+ do_request(r, lkb)
+ do_convert(r, lkb)
+ do_unlock(r, lkb)
+ do_cancel(r, lkb)
+
+ Stage 1 (lock, unlock) is mainly about checking input args and
+ splitting into one of the four main operations:
+
+ dlm_lock = request_lock
+ dlm_lock+CONVERT = convert_lock
+ dlm_unlock = unlock_lock
+ dlm_unlock+CANCEL = cancel_lock
+
+ Stage 2, xxxx_lock(), just finds and locks the relevant rsb which is
+ provided to the next stage.
+
+ Stage 3, _xxxx_lock(), determines if the operation is local or remote.
+ When remote, it calls send_xxxx(), when local it calls do_xxxx().
+
+ Stage 4, do_xxxx(), is the guts of the operation. It manipulates the
+ given rsb and lkb and queues callbacks.
+
+ For remote operations, send_xxxx() results in the corresponding do_xxxx()
+ function being executed on the remote node. The connecting send/receive
+ calls on local (L) and remote (R) nodes:
+
+ L: send_xxxx() -> R: receive_xxxx()
+ R: do_xxxx()
+ L: receive_xxxx_reply() <- R: send_xxxx_reply()

+ * This is the "low-level" comms layer.

+ *
+ * Cluster nodes are referred to by their nodeids. nodeids are

+ * responsibility. It is this layer's

+ * The comms level is two kernel threads that deal mainly with
+ * the receiving of messages from other nodes and passing them

+ * Extended attributes are stored directly in inodes (on file systems with

+ * contain the identical set of attributes may be shared among several inodes.
+ * Identical blocks are detected by keeping a cache of blocks that have
+ * recently been accessed.
+ *
+ * The attributes in inodes and on blocks have a different header; the entries
+ * are stored in the same format:
+ *
+ * +------------------+
+ * | header |
+ * | entry 1 | |
+ * | entry 2 | | growing downwards

+ * | value 2 | |
+ * +------------------+
+ *
+ * The header is followed by multiple entry descriptors. In disk blocks, the
+ * entry descriptors are kept sorted. In inodes, they are unsorted. The
+ * attribute values are aligned to the end of the block in no specific order.
+ *
+ * Locking strategy
+ * ----------------
+ * EXT4_I(inode)->i_file_acl is protected by EXT4_I(inode)->xattr_sem.

+ A cluster filesystem.
+
+ Allows a cluster of computers to simultaneously use a block device
+ that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads
+ and writes to the block device like a local filesystem, but also uses
+ a lock module to allow the computers coordinate their I/O so
+ filesystem consistency is maintained. One of the nifty features of
+ GFS is perfect consistency -- changes made to the filesystem on one
+ machine show up immediately on all other machines in the cluster.
+
+ To use the GFS2 filesystem, you will need to enable one or more of
+ the below locking modules. Documentation and utilities for GFS2 can

+ * Implements Extendible Hashing as described in:
+ * "Extendible Hashing" by Fagin, et al in
+ * __ACM Trans. on Database Systems__, Sept 1979.
+ *
+ *
+ * Here's the layout of dirents which is essentially the same as that of ext2
+ * within a single block. The field de_name_len is the number of bytes
+ * actually required for the name (no null terminator). The field de_rec_len
+ * is the number of bytes allocated to the dirent. The offset of the next
+ * dirent in the block is (dirent + dirent->de_rec_len). When a dirent is
+ * deleted, the preceding dirent inherits its allocated space, ie
+ * prev->de_rec_len += deleted->de_rec_len. Since the next dirent is obtained
+ * by adding de_rec_len to the current dirent, this essentially causes the
+ * deleted dirent to get jumped over when iterating through all the dirents.
+ *
+ * When deleting the first dirent in a block, there is no previous dirent so
+ * the field de_ino is set to zero to designate it as deleted. When allocating
+ * a dirent, gfs2_dirent_alloc iterates through the dirents in a block. If the
+ * first dirent has (de_ino == 0) and de_rec_len is large enough, this first
+ * dirent is allocated. Otherwise it must go through all the 'used' dirents
+ * searching for one in which the amount of total space minus the amount of
+ * used space will provide enough space for the new dirent.
+ *
+ * There are two types of blocks in which dirents reside. In a stuffed dinode,
+ * the dirents begin at offset sizeof(struct gfs2_dinode) from the beginning of
+ * the block. In leaves, they begin at offset sizeof(struct gfs2_leaf) from the
+ * beginning of the leaf block. The dirents reside in leaves when
+ *
+ * dip->i_di.di_flags & GFS2_DIF_EXHASH is true
+ *
+ * Otherwise, the dirents are "linear", within a single stuffed dinode block.
+ *
+ * When the dirents are in leaves, the actual contents of the directory file are
+ * used as an array of 64-bit block pointers pointing to the leaf blocks. The
+ * dirents are NOT in the directory file itself. There can be more than one
+ * block pointer in the array that points to the same leaf. In fact, when a
+ * directory is first converted from linear to exhash, all of the pointers
+ * point to the same leaf.
+ *
+ * When a leaf is completely full, the size of the hash table can be
+ * doubled unless it is already at the maximum size which is hard coded into
+ * GFS2_DIR_MAX_DEPTH. After that, leaves are chained together in a linked list,
+ * but never before the maximum hash table size has been reached.

+ * Quota change tags are associated with each transaction that allocates or
+ * deallocates space. Those changes are accumulated locally to each node (in a
+ * per-node file) and then are periodically synced to the quota file. This
+ * avoids the bottleneck of constantly touching the quota file, but introduces
+ * fuzziness in the current usage value of IDs that are being used on different
+ * nodes in the cluster simultaneously. So, it is possible for a user on
+ * multiple nodes to overrun their quota, but that overrun is controlable.
+ * Since quota tags are part of transactions, there is no need to a quota check
+ * program to be run on node crashes or anything like that.
+ *
+ * There are couple of knobs that let the administrator manage the quota
+ * fuzziness. "quota_quantum" sets the maximum time a quota change can be
+ * sitting on one node before being synced to the quota file. (The default is
+ * 60 seconds.) Another knob, "quota_scale" controls how quickly the frequency
+ * of quota file syncs increases as the user moves closer to their limit. The
+ * more frequent the syncs, the more accurate the quota enforcement, but that
+ * means that there is more contention between the nodes for the quota file.
+ * The default value is one. This sets the maximum theoretical quota overrun
+ * (with infinite node with infinite bandwidth) to twice the user's limit. (In
+ * practice, the maximum overrun you see should be much less.) A "quota_scale"
+ * number greater than one makes quota syncs more frequent and reduces the
+ * maximum overrun. Numbers less than one (but greater than zero) make quota
+ * syncs less frequent.
+ *
+ * GFS quotas also use per-ID Lock Value Blocks (LVBs) to cache the contents of
+ * the quota file, so it is not being constantly read.

+ * Journal revoke routines for the generic filesystem journaling code;
+ * part of the ext2fs journaling system.
+ *
+ * Revoke is the mechanism used to prevent old log records for deleted
+ * metadata from being replayed on top of newer data using the same
+ * blocks. The revoke mechanism is used in two separate places:
+ *
+ * + Commit: during commit we write the entire list of the current
+ * transaction's revoked blocks to the journal
+ *
+ * + Recovery: during recovery we record the transaction ID of all
+ * revoked blocks. If there are multiple revoke records in the log
+ * for a single block, only the last one counts, and if there is a log
+ * entry for a block beyond the last revoke, then that log entry still
+ * gets replayed.
+ *
+ * We can get interactions between revokes and new log data within a
+ * single transaction:
+ *
+ * Block is revoked and then journaled:
+ * The desired end result is the journaling of the new block, so we
+ * cancel the revoke before the transaction commits.
+ *
+ * Block is journaled and then revoked:
+ * The revoke must take precedence over the write of the block, so we
+ * need either to cancel the journal entry or to write the revoke
+ * later in the log than the log block. In this case, we choose the
+ * latter: journaling a block cancels any revoke record for that block
+ * in the current transaction, so any revoke for that block in the
+ * transaction must have happened after the block was journaled and so
+ * the revoke must take precedence.
+ *
+ * Block is revoked and then written as data:
+ * The data write is allowed to succeed, but the revoke is _not_
+ * cancelled. We still need to prevent old log records from
+ * overwriting the new data. We don't even need to clear the revoke
+ * bit here.
+ *
+ * Revoke information on buffers is a tri-state value:
+ *
+ * RevokeValid clear: no cached revoke status, need to look it up
+ * RevokeValid set, Revoked clear:
+ * buffer has not been revoked, and cancel_revoke
+ * need do nothing.
+ * RevokeValid set, Revoked set:
+ * buffer has been revoked.

+ * as in-use in the committed_data bitmap, so cannot be reused until
+ * the next transaction to delete the block commits. This means that
+ * leaving committing buffers dirty is quite safe: the disk blocks
+ * cannot be reallocated to a different file and so buffer aliasing is
+ * not possible.

+ *
+ * DLM_LKF_NOQUEUE
+ *
+ * Do not queue the lock request on the wait queue if it cannot be granted
+ * immediately. If the lock cannot be granted because of this flag, DLM will
+ * either return -EAGAIN from the dlm_lock call or will return 0 from
+ * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
+ *
+ * DLM_LKF_CANCEL
+ *
+ * Used to cancel a pending lock request or conversion. A converting lock is
+ * returned to its previously granted mode.
+ *
+ * DLM_LKF_CONVERT
+ *
+ * Indicates a lock conversion request. For conversions the name and namelen
+ * are ignored and the lock ID in the LKSB is used to identify the lock.
+ *
+ * DLM_LKF_VALBLK
+ *
+ * Requests DLM to return the current contents of the lock value block in the
+ * lock status block. When this flag is set in a lock conversion from PW or EX
+ * modes, DLM assigns the value specified in the lock status block to the lock
+ * value block of the lock resource. The LVB is a DLM_LVB_LEN size array
+ * containing application-specific information.
+ *
+ * DLM_LKF_QUECVT
+ *
+ * Force a conversion request to be queued, even if it is compatible with
+ * the granted modes of other locks on the same resource.
+ *
+ * DLM_LKF_IVVALBLK
+ *
+ * Invalidate the lock value block.
+ *
+ * DLM_LKF_CONVDEADLK
+ *
+ * Allows the dlm to resolve conversion deadlocks internally by demoting the
+ * granted mode of a converting lock to NL. The DLM_SBF_DEMOTED flag is
+ * returned for a conversion that's been effected by this.
+ *
+ * DLM_LKF_PERSISTENT
+ *
+ * Only relevant to locks originating in userspace. A persistent lock will not
+ * be removed if the process holding the lock exits.
+ *
+ * DLM_LKF_NODLKWT
+ * DLM_LKF_NODLCKBLK
+ *
+ * net yet implemented
+ *
+ * DLM_LKF_EXPEDITE
+ *
+ * Used only with new requests for NL mode locks. Tells the lock manager
+ * to grant the lock, ignoring other locks in convert and wait queues.
+ *
+ * DLM_LKF_NOQUEUEBAST
+ *
+ * Send blocking AST's before returning -EAGAIN to the caller. It is only
+ * used along with the NOQUEUE flag. Blocking AST's are not sent for failed
+ * NOQUEUE requests otherwise.
+ *
+ * DLM_LKF_HEADQUE
+ *
+ * Add a lock to the head of the convert or wait queue rather than the tail.
+ *
+ * DLM_LKF_NOORDER
+ *
+ * Disregard the standard grant order rules and grant a lock as soon as it
+ * is compatible with other granted locks.
+ *
+ * DLM_LKF_ORPHAN
+ *
+ * not yet implemented
+ *
+ * DLM_LKF_ALTPR
+ *
+ * If the requested mode cannot be granted immediately, try to grant the lock
+ * in PR mode instead. If this alternate mode is granted instead of the
+ * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
+ *
+ * DLM_LKF_ALTCW
+ *
+ * The same as ALTPR, but the alternate mode is CW.
+ *
+ * DLM_LKF_FORCEUNLOCK
+ *
+ * Unlock the lock even if it is converting or waiting or has sublocks.
+ * Only really for use by the userland device.c code.

- * Notifier chains are of three types:

* Atomic notifier chains: Chain callbacks run in interrupt/atomic

* Raw notifier chains: There are no restrictions on callbacks,
* registration, or unregistration. All locking and protection
* must be provided by the caller.
+ * SRCU notifier chains: A variant of blocking notifier chains, with
+ * the same restrictions.
*
* atomic_notifier_chain_register() may be called from an atomic context,
- * but blocking_notifier_chain_register() must be called from a process

+ * and srcu_notifier_chain_unregister() _must not_ be called from within
+ * the call chain.
+ *
+ * SRCU notifier chains are an alternative form of blocking notifier chains.
+ * They use SRCU (Sleepable Read-Copy Update) instead of rw-semaphores for
+ * protection of the chain links. This means there is _very_ low overhead
+ * in srcu_notifier_call_chain(): no cache bounces and no memory barriers.
+ * As compensation, srcu_notifier_chain_unregister() is rather expensive.
+ * SRCU notifier chains should be used when the chain will be called very
+ * often but notifier_blocks will seldom be removed. Also, SRCU notifier
+ * chains are slightly more difficult to use because they require special

- Because most/all of the sample data we pass in via pointers has

- disk), it would be nice to allow handling of multi-channel sample
- data without forcing user-level extraction of the relevant bytes.
-
- So, we need a way of specifying which channel to use (the WaveFront
- only handles mono samples in a given slot), and the only way to do
- this without using some struct other than wavefront_sample as the
- interface is the awful hack of using the unused bits in a
- wavefront_sample:
-
- Val Meaning
- --- -------
- 0 no channel selection (use channel 1, sample is MONO)
- 1 use first channel, and skip one
- 2 use second channel, and skip one
- 3 use third channel, and skip two
- 4 use fourth channel, skip three
- 5 use fifth channel, skip four
- 6 use six channel, skip five
-
-
- This can handle up to 4 channels, and anyone downloading >4 channels
- of sample data just to select one of them needs to find some tools
- like sox ...
-
- NOTE: values 0, 1 and 2 correspond to WF_CH_* above. This is

Major new features in SG 3.x driver (cf SG 2.x drivers)
- SG_IO ioctl() combines function if write() and read()
data into kernel buffers and then use the CPU to copy the data into the
user space (vice versa for writes). That is called "indirect" IO due to
the double handling of data. There are two methods offered to remove the
- redundant copy: 1) direct IO which uses the kernel kiobuf mechanism and
- 2) using the mmap() system call to map the reserve buffer (this driver has
- one reserve buffer per fd) into the user space. Both have their advantages.
+ redundant copy: 1) direct IO and 2) using the mmap() system call to map
+ the reserve buffer (this driver has one reserve buffer per fd) into the
+ user space. Both have their advantages.
In terms of absolute speed mmap() is faster. If speed is not a concern,
indirect IO should be fine. Read the documentation for more information.
- ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' may be
- needed. That pseudo file's content is defaulted to 0. **
+ ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
+ 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
+ That attribute is 0 by default. **
Historical note: this SCSI pass-through driver has been known as "sg" for
a decade. In broader kernel discussions "sg" is used to refer to scatter
http://www.torque.net/sg/p/sg_v3_ho.html
This is a rendering from DocBook source [change the extension to "sgml"
or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
+ The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
+ For more information see http://www.torque.net/sg/sg_io.html
The older, version 2 documents discuss the original sg interface in detail:
http://www.torque.net/sg/p/scsi-generic.txt
http://www.torque.net/sg/p/scsi-generic_long.txt
- A version of this document (potentially out of date) may also be found in
- the kernel source tree, probably at:
- Documentation/scsi/scsi-generic.txt .
+ Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
Utility and test programs are available at the sg web site. They are
- bundled as sg_utils (for the lk 2.2 series) and sg3_utils (for the
- lk 2.4 series).
-
- There is a HOWTO on the Linux SCSI subsystem in the lk 2.4 series at:
- http://www.linuxdoc.org/HOWTO/SCSI-2.4-HOWTO
+ packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
+ (for the lk 2.2 series).

- This code is NOT intended to be used for statistics collection,
- its purpose is to provide a base for statistical multiplexing
- for controlled load service.
- If you need only statistics, run a user level daemon which
- periodically reads byte counters.
-
- Unfortunately, rate estimation is not a very easy task.
- F.e. I did not find a simple way to estimate the current peak rate
- and even failed to formulate the problem 8)8)
-
- So I preferred not to built an estimator into the scheduler,
- but run this task separately.
- Ideally, it should be kernel thread(s), but for now it runs
- from timers, which puts apparent top bounds on the number of rated
- flows, has minimal overhead on small, but is enough
- to handle controlled load service, sets of aggregates.
-
- We measure rate over A=(1<<interval) seconds and evaluate EWMA:
-
- avrate = avrate*(1-W) + rate*W
-
- where W is chosen as negative power of 2: W = 2^(-ewma_log)
-
- The resulting time constant is:
-
- T = A/(-ln(1-W))
-
-
- NOTES.
-
- * The stored value for avbps is scaled by 2^5, so that maximal
- rate is ~1Gbit, avpps is scaled by 2^10.
-
- * Minimal interval is HZ/4=250msec (it is the greatest common divisor
- for HZ=100 and HZ=1024 8)), maximal interval
- is (HZ*2^EST_MAX_INTERVAL)/4 = 8sec. Shorter intervals
- are too expensive, longer ones can be implemented
- at user level painlessly.

- * ALi 5455 theory of operation
- *
- * The chipset provides three DMA channels that talk to an AC97
- * CODEC (AC97 is a digital/analog mixer standard). At its simplest
- * you get 48Khz audio with basic volume and mixer controls. At the
- * best you get rate adaption in the codec. We set the card up so
- * that we never take completion interrupts but instead keep the card
- * chasing its tail around a ring buffer. This is needed for mmap
- * mode audio and happens to work rather well for non-mmap modes too.
- *
- * The board has one output channel for PCM audio (supported) and
- * a stereo line in and mono microphone input. Again these are normally
- * locked to 48Khz only. Right now recording is not finished.
- *
- * There is no midi support, no synth support. Use timidity. To get
- * esd working you need to use esd -r 48000 as it won't probe 48KHz
- * by default. mpg123 can't handle 48Khz only audio so use xmms.
- *
- * If you need to force a specific rate set the clocking= option
- *

- * 06.27.2001 Initial version
- * 03.20.2002 Added mutex locks around read/write methods, to prevent

- * removed the counter/pointer fragment aligning at the end
- * of read/write methods [stevel].
- * 03.21.2002 Add support for coherent DMA on the audio read/write DMA
- * channels [stevel].

- * Special thanks to David C. Niemi, Jan Pfeifer
- *
- *
- * Module command line parameters:
- * none so far
- *
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * The card has both an FM and a Wavetable synth, but I have to figure
- * out first how to drive them...
- *
- * Revision history
- * 06.05.98 0.1 Initial release
- * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in cm_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.98 0.4 Don't allow excessive interrupt rates
- * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.98 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.98 0.7 Fix realplayer problems - dac.count issues
- * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.99 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 18.08.99 1.5 Only deallocate DMA buffer when unloading.
- * 02.09.99 1.6 Enable SPDIF LOOP
- * Change the mixer read back
- * 21.09.99 2.33 Use RCS version as driver version.
- * Add support for modem, S/PDIF loop and 4 channels.
- * (8738 only)
- * Fix bug cause x11amp cannot play.
- *
- * Fixes:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * 18/05/2001 - .bss nitpicks, fix a bug in set_dac_channels where it
- * was calling prog_dmabuf with s->lock held, call missing
- * unlock_kernel in cm_midi_release
- * 08/10/2001 - use set_current_state in some more places
- *
- * Carlos Eduardo Gorges <carlos@techlinux.com.br>
- * Fri May 25 2001
- * - SMP support ( spin[un]lock* revision )
- * - speaker mixer support
- * Mon Aug 13 2001
- * - optimizations and cleanups
- *
- * 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de>
- * Simon Braunschmidt <brasimon@web.de>
- * Sat Jan 31 2004
- * - provide support for opl3 FM by releasing IO range after initialization
- *
- * ChenLi Tien <cltien@cmedia.com.tw>
- * Mar 9 2004
- * - Fix S/PDIF out if spdif_loop enabled
- * - Load opl3 driver if enabled (fmio in proper range)
- * - Load mpu401 if enabled (mpuio in proper range)
- * Apr 5 2004
- * - Fix DUAL_DAC dma synchronization bug
- * - Check exist FM/MPU401 I/O before activate.
- * - Add AFTM_S16_BE format support, so MPlayer/Xine can play AC3/mutlichannel
- * on Mac
- * - Change to support kernel 2.6 so only small patch needed
- * - All parameters default to 0
- * - Add spdif_out to send PCM through S/PDIF out jack
- * - Add hw_copy to get 4-spaker output for general PCM/analog output
- *

-* /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
-* /dev/midi simple MIDI UART interface, no ioctl
-*
-* Modification History
-* 08/20/00 trw - silence and no stopping DAC until release
-* 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop.
-* 09/18/00 trw - added 16bit only record with conversion
-* 09/24/00 trw - added Enhanced Full duplex (separate simultaneous
-* capture/playback rates)
-* 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin
-* libOSSm.so)
-* 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal)
-* 11/03/00 trw - fixed interrupt loss/stutter, added debug.
-* 11/10/00 bkz - added __devinit to cs4281_hw_init()
-* 11/10/00 trw - fixed SMP and capture spinlock hang.
-* 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm.
-* 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix.
-* 12/08/00 trw - added PM support.
-* 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8
-* (RH/Dell base), 2.2.18, 2.2.12. cleaned up code mods by ident.
-* 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup.
-* 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use
-* defaultorder-100 as power of 2 for the buffer size. example:
-* 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size.

- * Special thanks to David C. Niemi
- *
- *
- * Module command line parameters:
- * lineout if 1 the LINE jack is used as an output instead of an input.
- * LINE then contains the unmixed dsp output. This can be used
- * to make the card a four channel one: use dsp to output two
- * channels to LINE and dac to output the other two channels to
- * SPKR. Set the mixer to only output synth to SPKR.
- * micbias sets the +5V bias to the mic if using an electretmic.
- *
- *
- * Note: sync mode is not yet supported (i.e. running dsp and dac from the same
- * clock source)
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/dsp1 additional DAC, like /dev/dsp, but output only,
- * only 5512, 11025, 22050 and 44100 samples/s,
- * outputs to mixer "SYNTH" setting
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- * there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- * Revision history
- * 26.03.1998 0.1 Initial release
- * 31.03.1998 0.2 Fix bug in GETOSPACE
- * 04.04.1998 0.3 Make it work (again) under 2.0.33
- * Fix mixer write operation not returning the actual
- * settings
- * 05.04.1998 0.4 First attempt at using the new PCI stuff
- * 29.04.1998 0.5 Fix hang when ^C is pressed on amp
- * 07.05.1998 0.6 Don't double lock around stop_*() in *_release()
- * 10.05.1998 0.7 First stab at a simple midi interface (no bells&whistles)
- * 14.05.1998 0.8 Don't allow excessive interrupt rates
- * 08.06.1998 0.9 First release using Alan Cox' soundcore instead of
- * miscdevice
- * 05.07.1998 0.10 Fixed the driver to correctly maintin OSS style volume
- * settings (not sure if this should be standard)
- * Fixed many references: f_flags should be f_mode
- * -- Gerald Britton <gbritton@mit.edu>
- * 03.08.1998 0.11 Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * Fixed mixer table thanks to Hakan.Lennestal@lu.erisoft.se
- * On module startup, set DAC2 to 11kSPS instead of 5.5kSPS,
- * as it produces an annoying ssssh in the lower sampling rate
- * Do not include modversions.h
- * 22.08.1998 0.12 Mixer registers actually have 5 instead of 4 bits
- * pointed out by Itai Nahshon
- * 31.08.1998 0.13 Fix realplayer problems - dac.count issues
- * 08.10.1998 0.14 Joystick support fixed
- * -- Oliver Neukum <c188@org.chemie.uni-muenchen.de>
- * 10.12.1998 0.15 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.1998 0.16 Don't wake up app until there are fragsize bytes to read/write
- * 06.01.1999 0.17 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.18 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.19 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.20 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Note: joystick address handling might still be wrong on archs
- * other than i386
- * 10.05.1999 0.21 Added support for an electret mic for SB PCI64
- * to the Linux kernel sound driver. This mod also straighten
- * out the question marks around the mic impedance setting
- * (micz). From Kim.Berts@fisub.mail.abb.com
- * 11.05.1999 0.22 Implemented the IMIX call to mute recording monitor.
- * Guenter Geiger <geiger@epy.co.at>
- * 15.06.1999 0.23 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.24 Add pci_set_master
- * 02.08.1999 0.25 Added workaround for the "phantom write" bug first
- * documented by Dave Sharpless from Anchor Games
- * 03.08.1999 0.26 adapt to Linus' new __setup/__initcall
- * added kernel command line option "es1370=joystick[,lineout[,micbias]]"
- * removed CONFIG_SOUND_ES1370_JOYPORT_BOOT kludge
- * 12.08.1999 0.27 module_init/__setup fixes
- * 19.08.1999 0.28 SOUND_MIXER_IMIX fixes, reported by Gianluca <gialluca@mail.tiscalinet.it>
- * 31.08.1999 0.29 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.30 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 28.10.1999 0.31 More waitqueue races fixed
- * 08.01.2000 0.32 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.33 Use pci_alloc_consistent and pci_register_driver
- * 21.11.2000 0.34 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.35 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 07.01.2001 0.36 Timeout change in wrcodec as requested by Frank Klemm <pfk@fuchs.offl.uni-jena.de>
- * 31.01.2001 0.37 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 03.01.2003 0.38 open_mode fixes from Georg Acher <acher@in.tum.de>
- *
- * some important things missing in Ensoniq documentation:
- *
- * Experimental PCLKDIV results: play the same waveforms on both DAC1 and DAC2
- * and vary PCLKDIV to obtain zero beat.
- * 5512sps: 254
- * 44100sps: 30
- * seems to be fs = 1411200/(PCLKDIV+2)
- *
- * should find out when curr_sample_ct is cleared and
- * where exactly the CCB fetches data
- *
- * The card uses a 22.5792 MHz crystal.
- * The LINEIN jack may be converted to an AOUT jack by
- * setting pin 47 (XCTL0) of the ES1370 to high.
- * Pin 48 (XCTL1) of the ES1370 sets the +5V bias for an electretmic
- *

- * Module command line parameters:
- * none so far
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * Revision history
- * 10.11.1998 0.1 Initial release (without any hardware)
- * 22.03.1999 0.2 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.3 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * 15.06.1999 0.4 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.5 Add pci_set_master
- * 12.08.1999 0.6 Fix MIDI UART crashing the driver
- * Changed mixer semantics from OSS documented
- * behaviour to OSS "code behaviour".
- * Recording might actually work now.
- * The real DDMA controller address register is at PCI config
- * 0x60, while the register at 0x18 is used as a placeholder
- * register for BIOS address allocation. This register
- * is supposed to be copied into 0x60, according
- * to the Solo1 datasheet. When I do that, I can access
- * the DDMA registers except the mask bit, which
- * is stuck at 1. When I copy the contents of 0x18 +0x10
- * to the DDMA base register, everything seems to work.
- * The fun part is that the Windows Solo1 driver doesn't
- * seem to do these tricks.
- * Bugs remaining: plops and clicks when starting/stopping playback
- * 31.08.1999 0.7 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.8 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 07.10.1999 0.9 Fix initialization; complain if sequencer writes time out
- * Revised resource grabbing for the FM synthesizer
- * 28.10.1999 0.10 More waitqueue races fixed
- * 09.12.1999 0.11 Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M)
- * Disabling recording on Alpha
- * 12.01.2000 0.12 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * Integrated (aka redid 8-)) APM support patch by Zach Brown
- * 07.02.2000 0.13 Use pci_alloc_consistent and pci_register_driver
- * 19.02.2000 0.14 Use pci_dma_supported to determine if recording should be disabled
- * 13.03.2000 0.15 Reintroduce initialization of a couple of PCI config space registers
- * 21.11.2000 0.16 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.17 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 31.01.2001 0.18 Register/Unregister gameport, original patch from
- * Nathaniel Daw <daw@cs.cmu.edu>
- * Fix SETTRIGGER non OSS API conformity
- * 10.03.2001 provide abs function, prevent picking up a bogus kernel macro
- * for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
- * 15.05.2001 pci_enable_device moved, return values in probe cleaned
- * up. Marcus Meissner <mm@caldera.de>
- * 22.05.2001 0.19 more cleanups, changed PM to PCI 2.4 style, got rid
- * of global list of devices, using pci device data.
- * Marcus Meissner <mm@caldera.de>
- * 03.01.2003 0.20 open_mode fixes from Georg Acher <acher@in.tum.de>

- This is a sound driver for ASP's and Lasi's Harmony sound chip
- and is unlikely to be used for anything other than on a HP PA-RISC.
-
- Harmony is found in HP 712s, 715/new and many other GSC based machines.
- On older 715 machines you'll find the technically identical chip
- called 'Vivace'. Both Harmony and Vicace are supported by this driver.

- *
- * Based heavily on SonicVibes.c:
- * Copyright (C) 1998-1999 Thomas Sailer (sailer@ife.ee.ethz.ch)
- *
- * Heavily modified by Zach Brown <zab@zabbo.net> based on lunch
- * with ESS engineers. Many thanks to Howard Kim for providing
- * contacts and hardware. Honorable mention goes to Eric
- * Brombaugh for all sorts of things. Best regards to the

- *
- * Supported devices:
- * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- *
- * Hardware Description
- *
- * A working Maestro setup contains the Maestro chip wired to a
- * codec or 2. In the Maestro we have the APUs, the ASSP, and the
- * Wavecache. The APUs can be though of as virtual audio routing
- * channels. They can take data from a number of sources and perform
- * basic encodings of the data. The wavecache is a storehouse for
- * PCM data. Typically it deals with PCI and interracts with the
- * APUs. The ASSP is a wacky DSP like device that ESS is loth
- * to release docs on. Thankfully it isn't required on the Maestro
- * until you start doing insane things like FM emulation and surround
- * encoding. The codecs are almost always AC-97 compliant codecs,
- * but it appears that early Maestros may have had PT101 (an ESS
- * part?) wired to them. The only real difference in the Maestro
- * families is external goop like docking capability, memory for
- * the ASSP, and initialization differences.
- *
- * Driver Operation
- *
- * We only drive the APU/Wavecache as typical DACs and drive the
- * mixers in the codecs. There are 64 APUs. We assign 6 to each
- * /dev/dsp? device. 2 channels for output, and 4 channels for
- * input.
- *
- * Each APU can do a number of things, but we only really use
- * 3 basic functions. For playback we use them to convert PCM
- * data fetched over PCI by the wavecahche into analog data that
- * is handed to the codec. One APU for mono, and a pair for stereo.
- * When in stereo, the combination of smarts in the APU and Wavecache
- * decide which wavecache gets the left or right channel.
- *
- * For record we still use the old overly mono system. For each in
- * coming channel the data comes in from the codec, through a 'input'
- * APU, through another rate converter APU, and then into memory via
- * the wavecache and PCI. If its stereo, we mash it back into LRLR in
- * software. The pass between the 2 APUs is supposedly what requires us
- * to have a 512 byte buffer sitting around in wavecache/memory.
- *
- * The wavecache makes our life even more fun. First off, it can
- * only address the first 28 bits of PCI address space, making it
- * useless on quite a few architectures. Secondly, its insane.
- * It claims to fetch from 4 regions of PCI space, each 4 meg in length.
- * But that doesn't really work. You can only use 1 region. So all our
- * allocations have to be in 4meg of each other. Booo. Hiss.
- * So we have a module parameter, dsps_order, that is the order of
- * the number of dsps to provide. All their buffer space is allocated
- * on open time. The sonicvibes OSS routines we inherited really want
- * power of 2 buffers, so we have all those next to each other, then
- * 512 byte regions for the recording wavecaches. This ends up
- * wasting quite a bit of memory. The only fixes I can see would be
- * getting a kernel allocator that could work in zones, or figuring out
- * just how to coerce the WP into doing what we want.
- *
- * The indirection of the various registers means we have to spinlock
- * nearly all register accesses. We have the main register indirection
- * like the wave cache, maestro registers, etc. Then we have beasts
- * like the APU interface that is indirect registers gotten at through
- * the main maestro indirection. Ouch. We spinlock around the actual
- * ports on a per card basis. This means spinlock activity at each IO
- * operation, but the only IO operation clusters are in non critical
- * paths and it makes the code far easier to follow. Interrupts are
- * blocked while holding the locks because the int handler has to
- * get at some of them :(. The mixer interface doesn't, however.
- * We also have an OSS state lock that is thrown around in a few
- * places.
- *
- * This driver has brute force APM suspend support. We catch suspend
- * notifications and stop all work being done on the chip. Any people
- * that try between this shutdown and the real suspend operation will
- * be put to sleep. When we resume we restore our software state on
- * the chip and wake up the people that were using it. The code thats
- * being used now is quite dirty and assumes we're on a uni-processor
- * machine. Much of it will need to be cleaned up for SMP ACPI or
- * similar.
- *
- * We also pay attention to PCI power management now. The driver
- * will power down units of the chip that it knows aren't needed.
- * The WaveProcessor and company are only powered on when people
- * have /dev/dsp*s open. On removal the driver will
- * power down the maestro entirely. There could still be
- * trouble with BIOSen that magically change power states
- * themselves, but we'll see.
- *
- * History
- * v0.15 - May 21 2001 - Marcus Meissner <mm@caldera.de>
- * Ported to Linux 2.4 PCI API. Some clean ups, global devs list

- * I need to thank many people for helping make this driver happen.
- * As always, Eric Brombaugh was a hacking machine and killed many bugs
- * that I was too dumb to notice. Howard Kim at ESS provided reference boards
- * and as much docs as he could. Todd and Mick at Dell tested snapshots on
- * an army of laptops. msw and deviant at Red Hat also humoured me by hanging
- * their laptops every few hours in the name of science.
- *
- * Shouts go out to Mike "DJ XPCom" Ang.
- *
- * History
- * v1.23 - Jun 5 2002 - Michael Olson <olson@cs.odu.edu>
- * added a module option to allow selection of GPIO pin number
- * for external amp
- * v1.22 - Feb 28 2001 - Zach Brown <zab@zabbo.net>
- * allocate mem at insmod/setup, rather than open
- * limit pci dma addresses to 28bit, thanks guys.
- * v1.21 - Feb 04 2001 - Zach Brown <zab@zabbo.net>
- * fix up really dumb notifier -> suspend oops
- * v1.20 - Jan 30 2001 - Zach Brown <zab@zabbo.net>
- * get rid of pm callback and use pci_dev suspend/resume instead
- * m3_probe cleanups, including pm oops think-o
- * v1.10 - Jan 6 2001 - Zach Brown <zab@zabbo.net>
- * revert to lame remap_page_range mmap() just to make it work
- * record mmap fixed.
- * fix up incredibly broken open/release resource management
- * duh. fix record format setting.
- * add SMP locking and cleanup formatting here and there
- * v1.00 - Dec 16 2000 - Zach Brown <zab@zabbo.net>
- * port to sexy 2.4 interfaces
- * properly align instance allocations so recording works
- * clean up function namespace a little :/
- * update PCI IDs based on mail from ESS
- * arbitrarily bump version number to show its 2.4 now,
- * 2.2 will stay 0., oss_audio port gets 2.
- * v0.03 - Nov 05 2000 - Zach Brown <zab@zabbo.net>
- * disable recording but allow dsp to be opened read
- * pull out most silly compat defines
- * v0.02 - Nov 04 2000 - Zach Brown <zab@zabbo.net>
- * changed clocking setup for m3, slowdown fixed.
- * codec reset is hopefully reliable now
- * rudimentary apm/power management makes suspend/resume work
- * v0.01 - Oct 31 2000 - Zach Brown <zab@zabbo.net>
- * first release
- * v0.00 - Sep 09 2000 - Zach Brown <zab@zabbo.net>
- * first pass derivation from maestro.c
- *
- * TODO
- * in/out allocated contiguously so fullduplex mmap will work?
- * no beep on init (mute)
- * resetup msrc data memory if freq changes?
- *
- * --
- *
- * Allow me to ramble a bit about the m3 architecture. The core of the
- * chip is the 'assp', the custom ESS dsp that runs the show. It has
- * a small amount of code and data ram. ESS drops binary dsp code images
- * on our heads, but we don't get to see specs on the dsp.
- *
- * The constant piece of code on the dsp is the 'kernel'. It also has a
- * chunk of the dsp memory that is statically set aside for its control
- * info. This is the KDATA defines in maestro3.h. Part of its core
- * data is a list of code addresses that point to the pieces of DSP code
- * that it should walk through in its loop. These other pieces of code
- * do the real work. The kernel presumably jumps into each of them in turn.
- * These code images tend to have their own data area, and one can have
- * multiple data areas representing different states for each of the 'client
- * instance' code portions. There is generally a list in the kernel data
- * that points to the data instances for a given piece of code.
- *
- * We've only been given the binary image for the 'minisrc', mini sample
- * rate converter. This is rather annoying because it limits the work
- * we can do on the dsp, but it also greatly simplifies the job of managing
- * dsp data memory for the code and data for our playing streams :). We
- * statically allocate the minisrc code into a region we 'know' to be free
- * based on the map of the binary kernel image we're loading. We also
- * statically allocate the data areas for the maximum number of pcm streams
- * we can be dealing with. This max is set by the length of the static list
- * in the kernel data that records the number of minisrc data regions we
- * can have. Thats right, all software dsp mixing with static code list
- * limits. Rock.
- *
- * How sound goes in and out is still a relative mystery. It appears
- * that the dsp has the ability to get input and output through various
- * 'connections'. To do IO from or to a connection, you put the address
- * of the minisrc client area in the static kernel data lists for that
- * input or output. so for pcm -> dsp -> mixer, we put the minisrc data
- * instance in the DMA list and also in the list for the mixer. I guess
- * it Just Knows which is in/out, and we give some dma control info that
- * helps. There are all sorts of cool inputs/outputs that it seems we can't
- * use without dsp code images that know how to use them.
- *
- * So at init time we preload all the memory allocation stuff and set some
- * system wide parameters. When we really get a sound to play we build
- * up its minisrc header (stream parameters, buffer addresses, input/output
- * settings). Then we throw its header on the various lists. We also
- * tickle some KDATA settings that ask the assp to raise clock interrupts
- * and do some amount of software mixing before handing data to the ac97.
- *
- * Sorry for the vague details. Feel free to ask Eric or myself if you
- * happen to be trying to use this driver elsewhere. Please accept my
- * apologies for the quality of the OSS support code, its passed through
- * too many hands now and desperately wants to be rethought.

-
- Modifications - Heiko Purnhagen <purnhage@tnt.uni-hannover.de>
- HP20020108 fixed handling of "large" read()
- HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
- HP20020118 made mixer ioctl and handling of devices>1 more safe
- HP20020201 fixed handling of "large" read() properly
- added REV 1.5 S/P-DIF receiver support
- SNDCTL_DSP_SPEED now returns the actual speed
- * 10 Aug 2002: added synchronize_irq() again
-
-TODO:
- - test more than one card --- done
- - check for pci IOREGION (see es1370) in rme96xx_probe ??
- - error detection
- - mmap interface
- - mixer mmap interface
- - mixer ioctl
- - get rid of noise upon first open (why ??)
- - allow multiple open (at least for read)
- - allow multiple open for non overlapping regions
- - recheck the multiple devices part (offsets of different devices, etc)
- - do decent draining in _release --- done
- - SMP support
- - what about using fragstotal>2 for small fragsize? (HP20020118)
- - add support for AFMT_S32_LE

- * Special thanks to David C. Niemi
- *
- *
- * Module command line parameters:
- * none so far
- *
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * The card has both an FM and a Wavetable synth, but I have to figure
- * out first how to drive them...
- *
- * Revision history
- * 06.05.1998 0.1 Initial release
- * 10.05.1998 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.1998 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in sv_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.1998 0.4 Don't allow excessive interrupt rates
- * 08.06.1998 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.7 Fix realplayer problems - dac.count issues
- * 10.12.1998 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.1998 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.1999 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 05.04.1999 0.13 added code to sv_read and sv_write which should detect
- * lockups of the sound chip and revive it. This is basically
- * an ugly hack, but at least applications using this driver
- * won't hang forever. I don't know why these lockups happen,
- * it might well be the motherboard chipset (an early 486 PCI
- * board with ALI chipset), since every busmastering 100MB
- * ethernet card I've tried (Realtek 8139 and Macronix tulip clone)
- * exhibit similar behaviour (they work for a couple of packets
- * and then lock up and can be revived by ifconfig down/up).
- * 07.04.1999 0.14 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Note: dmaio hack might still be wrong on archs other than i386
- * 15.06.1999 0.15 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.16 Add pci_set_master
- * 03.08.1999 0.17 adapt to Linus' new __setup/__initcall
- * added kernel command line options "sonicvibes=reverb" and "sonicvibesdmaio=dmaioaddr"
- * 12.08.1999 0.18 module_init/__setup fixes
- * 24.08.1999 0.19 get rid of the dmaio kludge, replace with allocate_resource
- * 31.08.1999 0.20 add spin_lock_init
- * use new resource allocation to allocate DDMA IO space
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.21 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 28.10.1999 0.22 More waitqueue races fixed
- * 01.12.1999 0.23 New argument to allocate_resource
- * 07.12.1999 0.24 More allocate_resource semantics change
- * 08.01.2000 0.25 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * use Martin Mares' pci_assign_resource
- * 07.02.2000 0.26 Use pci_alloc_consistent and pci_register_driver
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.28 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 31.01.2001 0.29 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 18.05.2001 0.30 PCI probing and error values cleaned up by Marcus
- * Meissner <mm@caldera.de>
- * 03.01.2003 0.31 open_mode fixes from Georg Acher <acher@in.tum.de>

- * sound/wavfront.c
- *
- * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
- *
- * This driver supports the onboard wavetable synthesizer (an ICS2115),
- * including patch, sample and program loading and unloading, conversion
- * of GUS patches during loading, and full user-level access to all
- * WaveFront commands. It tries to provide semi-intelligent patch and
- * sample management as well.
- *
- * It also provides support for the ICS emulation of an MPU-401. Full
- * support for the ICS emulation's "virtual MIDI mode" is provided in
- * wf_midi.c.
- *
- * Support is also provided for the Tropez Plus' onboard FX processor,
- * a Yamaha YSS225. Currently, code exists to configure the YSS225,
- * and there is an interface allowing tweaking of any of its memory
- * addresses. However, I have been unable to decipher the logical
- * positioning of the configuration info for various effects, so for
- * now, you just get the YSS225 in the same state as Turtle Beach's
- * "SETUPSND.EXE" utility leaves it.
- *
- * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
- * This chip also controls the configuration of the card: the wavefront
- * synth is logical unit 4.
- *
- *
- * Supported devices:
- *
- * /dev/dsp - using cs4232+ad1848 modules, OSS compatible
- * /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
- * /dev/synth00 - raw synth interface

- is done purely at user level: there is no WFB parser in
- this driver, and so a complete reset (back to General MIDI,
- or theoretically some other configuration) is the

- * sound/oss/wf_midi.c
- *
- * The low level driver for the WaveFront ICS2115 MIDI interface(s)
- * Note that there is also an MPU-401 emulation (actually, a UART-401
- * emulation) on the CS4232 on the Tropez Plus. This code has nothing
- * to do with that interface at all.
- *
- * The interface is essentially just a UART-401, but is has the
- * interesting property of supporting what Turtle Beach called
- * "Virtual MIDI" mode. In this mode, there are effectively *two*
- * MIDI buses accessible via the interface, one that is routed
- * solely to/from the external WaveFront synthesizer and the other
- * corresponding to the pin/socket connector used to link external
- * MIDI devices to the board.
- *
- * This driver fully supports this mode, allowing two distinct
- * midi devices (/dev/midiNN and /dev/midiNN+1) to be used
- * completely independently, giving 32 channels of MIDI routing,
- * 16 to the WaveFront synth and 16 to the external MIDI bus.
- *
- * Switching between the two is accomplished externally by the driver
- * using the two otherwise unused MIDI bytes. See the code for more details.
- *
- * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see wavefront.c)
- *
- * The main reason to turn off Virtual MIDI mode is when you want to
- * tightly couple the WaveFront synth with an external MIDI
- * device. You won't be able to distinguish the source of any MIDI
- * data except via SysEx ID, but thats probably OK, since for the most
- * part, the WaveFront won't be sending any MIDI data at all.
- *
- * The main reason to turn on Virtual MIDI Mode is to provide two
- * completely independent 16-channel MIDI buses, one to the
- * WaveFront and one to any external MIDI devices. Given the 32
- * voice nature of the WaveFront, its pretty easy to find a use
- * for all 16 channels driving just that synth.
- *

- * TODO:
- * - Use P44Slot for 44.1 playback (beware of idle buzzing in P44Slot).
- * - 96KHz playback for DVD - use pitch of 2.0.
- * - Retain DMA buffer on close, do not wait the end of frame.
- * - Resolve XXX tagged questions.
- * - Cannot play 5133Hz.
- * - 2001/01/07 Consider if we can remove voice_lock, like so:
- * : Allocate/deallocate voices in open/close under semafore.
- * : We access voices in interrupt, that only for pcms that open.
- * voice_lock around playback_prepare closes interrupts for insane duration.
- * - Revisit the way voice_alloc is done - too confusing, overcomplicated.
- * Should support various channel types, however.
- * - Remove prog_dmabuf from read/write, leave it in open.
- * - 2001/01/07 Replace the OPL3 part of CONFIG_SOUND_YMFPCI_LEGACY code with
- * native synthesizer through a playback slot.
- * - 2001/11/29 ac97_save_state
- * Talk to Kai to remove ac97_save_state before it's too late!
- * - Second AC97
- * - Restore S/PDIF - Toshibas have it.
- *
- * Kai used pci_alloc_consistent for DMA buffer, which sounds a little
- * unconventional. However, given how small our fragments can be,
- * a little uncached access is perhaps better than endless flushing.
- * On i386 and other I/O-coherent architectures pci_alloc_consistent
- * is entirely harmless.
