17 years agomca: add integrated device bus matching
James Bottomley [Wed, 9 May 2007 09:33:30 +0000 (02:33 -0700)]
mca: add integrated device bus matching

The MCA bus has a few "integrated" functions, which are effectively virtual
slots on the bus.  The problem is that these special functions don't have
dedicated pos IDs, so we have to manufacture ids for them outside the pos
space ...  and these ids can't be matched by the standard matching function,
so add a special registration that requests a list of pos ids or a particular
integrated function.

fix leaky resv_huge_pages when cpuset is in use

The internal hugetlb resv_huge_pages variable can permanently leak nonzero
value in the error path of hugetlb page fault handler when hugetlb page is
used in combination of cpuset.  The leaked count can permanently trap N
number of hugetlb pages in unusable "reserved" state.

Steps to reproduce the bug:

  (1) create two cpuset, user1 and user2
  (2) reserve 50 htlb pages in cpuset user1
  (3) attempt to shmget/shmat 50 htlb page inside cpuset user2
  (4) kernel oom the user process in step 3
  (5) ipcrm the shm segment

At this point resv_huge_pages will have a count of 49, even though
there are no active hugetlbfs file nor hugetlb shared memory segment
in the system.  The leak is permanent and there is no recovery method
other than system reboot. The leaked count will hold up all future use
of that many htlb pages in all cpusets.

The culprit is that the error path of alloc_huge_page() did not
properly undo the change it made to resv_huge_page, causing
inconsistent state.

dm log: fix resume failed log device

This patch removes the possibility of having uninitialized log state if the
log device has failed.

When a mirror resumes operation, it calls 'resume' on the logging module.  If
disk based logging is being used, the log device is read to fill in the log
state.  If the log device has failed, we cannot simply return, because this
would leave the in-memory log state uninitialized.  Instead, we assume all
regions are out-of-sync and reset the log state.  Failure to do this could
result in the logging code reporting a region as in-sync, even though it
isn't; which could result in a corrupted mirror.

This patch adds the ability to specify desired features in the mirror

The first feature of interest is "handle_errors".  Currently, mirroring will
ignore any I/O errors from the devices.  Subsequent patches will check for
this flag and handle the errors.  If flag/feature is not present, mirror will

[SPARC64] PCI: Use root list of pbm's instead of pci_controller_info's

The idea is to move more and more things into the pbm,
with the eventual goal of eliminating the pci_controller_info
entirely as there really isn't any need for it.

This stage of the transformations requires some reworking of
the PCI error interrupt handling.

It might be tricky to get rid of the pci_controller_info parenting for
a few reasons:

1) When we get an uncorrectable or correctable error we want
   to interrogate the IOMMU and streaming cache of both
   PBMs for error status.  These errors come from the UPA
   front-end which is shared between the two PBM PCI bus
   segments.

   Historically speaking this is why I choose the datastructure
   hierarchy of pci_controller_info-->pci_pbm_info

2) The probing does a portid/devhandle match to look for the
   'other' pbm, but this is entirely an artifact and can be
   eliminated trivially.

What we could do to solve #1 is to have a "buddy" pointer from one pbm
to another.

17 years agommc: use lock instead of claim in debug check
Pierre Ossman [Tue, 8 May 2007 20:35:17 +0000 (22:35 +0200)]
mmc: use lock instead of claim in debug check

As mmc_detect_change() can be called from irq context, using
claim (which can sleep) is inherently unsafe. Use the host
spinlock instead, which also is faster.

17 years agodisable socket power in adapter driver instead of media one
Alex Dubov [Wed, 2 May 2007 03:14:55 +0000 (20:14 -0700)]
disable socket power in adapter driver instead of media one

Socket power must be fully controlled by adapter driver. This also prevents
unnecessary power-off of the socket when media driver is unloaded, yet
media remains in the socket.
