* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).

*
* Framework borrowed from Bart Hartgers's als4000.c.
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
* (3 weeks' worth of evenings filled with driver work).
* (and no, I did NOT go the easy way: to pick up a SB PCI128 for 9 Euros)
*
+ * It is quite likely that the AZF3328 chip is the PCI cousin of the
+ * AZF3318 ("azt1020 pnp", "MM Pro 16") ISA chip, given very similar specs.
+ *
* The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
- * for compatibility reasons) has the following features:
+ * for compatibility reasons) from Azfin (joint-venture of Aztech and Fincitec,
+ * Fincitec acquired by National Semiconductor in 2002, together with the
+ * Fincitec-related company ARSmikro) has the following features:
*
+ * - compatibility & compliance:
+ * - Microsoft PC 97 ("PC 97 Hardware Design Guide",
+ * http://www.microsoft.com/whdc/archive/pcguides.mspx)
+ * - Microsoft PC 98 Baseline Audio
+ * - MPU401 UART
+ * - Sound Blaster Emulation (DOS Box)
* - builtin AC97 conformant codec (SNR over 80dB)
* Note that "conformant" != "compliant"!! this chip's mixer register layout
* *differs* from the standard AC97 layout:
* addresses illegally. So far unfortunately it looks like the very flexible
* ALSA AC97 support is still not enough to easily compensate for such a
* grave layout violation despite all tweaks and quirks mechanisms it offers.
- * - builtin genuine OPL3
+ * - builtin genuine OPL3 - verified to work fine, 20080506
* - full duplex 16bit playback/record at independent sampling rate
- * - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
+ * - MPU401 (+ legacy address support, claimed by one official spec sheet)
+ * FIXME: how to enable legacy addr??
* - game port (legacy address support)
- * - builtin 3D enhancement (said to be YAMAHA Ymersion)
* - builtin DirectInput support, helps reduce CPU overhead (interrupt-driven
- * features supported)
+ * features supported). - See common term "Digital Enhanced Game Port"...
+ * (probably DirectInput 3.0 spec - confirm)
+ * - builtin 3D enhancement (said to be YAMAHA Ymersion)
* - built-in General DirectX timer having a 20 bits counter
* with 1us resolution (see below!)
- * - I2S serial port for external DAC
+ * - I2S serial output port for external DAC
* - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
* - supports hardware volume control
* - single chip low cost solution (128 pin QFP)
* - supports programmable Sub-vendor and Sub-system ID
* required for Microsoft's logo compliance (FIXME: where?)
+ * At least the Trident 4D Wave DX has one bit somewhere
+ * to enable writes to PCI subsystem VID registers, that should be it.
+ * This might easily be in extended PCI reg space, since PCI168 also has
+ * some custom data starting at 0x80. What kind of config settings
+ * are located in our extended PCI space anyway??
* - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
*
* Note that this driver now is actually *better* than the Windows driver,
* - "timidity -iAv -B2,8 -Os -EFreverb=0"
* - "pmidi -p 128:0 jazz.mid"
*
+ * OPL3 hardware playback testing, try something like:
+ * cat /proc/asound/hwdep
+ * and
+ * aconnect -o
+ * Then use
+ * sbiload -Dhw:x,y --opl3 /usr/share/sounds/opl3/std.o3 ......./drums.o3
+ * where x,y is the xx-yy number as given in hwdep.
+ * Then try
+ * pmidi -p a:b jazz.mid
+ * where a:b is the client number plus 0 usually, as given by aconnect above.
+ * Oh, and make sure to unmute the FM mixer control (doh!)
+ * NOTE: power use during OPL3 playback is _VERY_ high (70W --> 90W!)
+ * despite no CPU activity, possibly due to hindering ACPI idling somehow.
+ * Shouldn't be a problem of the AZF3328 chip itself, I'd hope.
+ * Higher PCM / FM mixer levels seem to conflict (causes crackling),
+ * at least sometimes. Maybe even use with hardware sequencer timer above :)
+ * adplay/adplug-utils might soon offer hardware-based OPL3 playback, too.
+ *
* Certain PCI versions of this card are susceptible to DMA traffic underruns
* in some systems (resulting in sound crackling/clicking/popping),
* probably because they don't have a DMA FIFO buffer or so.
* better than a VIA, yet ironically I still get crackling, like many other
* people with the same chipset.
* Possible remedies:
+ * - use speaker (amplifier) output instead of headphone output
+ * (in case crackling is due to overloaded output clipping)
* - plug card into a different PCI slot, preferrably one that isn't shared
* too much (this helps a lot, but not completely!)
* - get rid of PCI VGA card, use AGP instead
* - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
* Not too helpful.
* - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
- *
+ *
* BUGS
- * - full-duplex might *still* be problematic, not fully tested recently
+ * - full-duplex might *still* be problematic, however a recent test was fine
* - (non-bug) "Bass/Treble or 3D settings don't work" - they do get evaluated
* if you set PCM output switch to "pre 3D" instead of "post 3D".
* If this can't be set, then get a mixer application that Isn't Stupid (tm)
* (e.g. kmix, gamix) - unfortunately several are!!
- *
+ * - locking is not entirely clean, especially the audio stream activity
+ * ints --> may be racy
+ * - an _unconnected_ secondary joystick at the gameport will be reported
+ * to be "active" (floating values, not precisely -1) due to the way we need
+ * to read the Digital Enhanced Game Port. Not sure whether it is fixable.
+ *
* TODO
* - test MPU401 MIDI playback etc.
- * - add some power micro-management (disable various units of the card
- * as long as they're unused). However this requires I/O ports which I
+ * - add more power micro-management (disable various units of the card
+ * as long as they're unused). However this requires more I/O ports which I
* haven't figured out yet and which thus might not even exist...
* The standard suspend/resume functionality could probably make use of
* some improvement, too...
* - figure out some cleverly evil scheme to possibly make ALSA AC97 code
* fully accept our quite incompatible ""AC97"" mixer and thus save some
* code (but I'm not too optimistic that doing this is possible at all)
+ * - use MMIO (memory-mapped I/O)? Slightly faster access, e.g. for gameport.
