Modules: AZT3328 driver this is now an even much more reworked patch (#3) for my azt3328.c ALSA driver. IOW I spent another 4 evenings to get the sequencer timer to work properly (my head is still hurting) and do lots of other cleanups. Note that despite the extensive sequencer timer additions, the driver object is still only 2kB bigger than the previous version, due to those many optimizations... Changes in version #3: - fully working ALSA sequencer timer support for the card's 1024000Hz DirectX timer (downscaling adjustable via seqtimer_scaling module param) - an insane amount of code optimizations - many, many cleanups Changes in version #2: - FOUND the 1us DirectX timer area (yay!), made the code respect it properly - renamed some 'weird' mixer control names according to ControlNames.txt - cleanup unneeded debug messages, reformatting - improved I/O register documentation - constified many more structs Changes in version #1: - improves/fixes some fatal playback/recording interaction - improves IRQ handler performance (and actually fixes some weird code) - coalesces some I/O accesses - slightly improves I/O interface documentation - improves/fixes logging - defines out some less important debug code - constifies some data Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
|
|
* Copyright (C) 2002, 2005 by Andreas Mohr <andi AT lisas.de>
|
|
*
|
|
* Framework borrowed from Bart Hartgers's als4000.c.
|
|
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
|
|
* found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
|
|
* Other versions are:
|
|
* PCI168 A(W), sub ID 1800
|
|
* PCI168 A/AP, sub ID 8000
|
|
* Please give me feedback in case you try my driver with one of these!!

|
|
* NOTES
|
|
* Since Aztech does not provide any chipset documentation,
|
|
* even on repeated request to various addresses,
|
|
* and the answer that was finally given was negative
|
|
* (and I was stupid enough to manage to get hold of a PCI168 soundcard
|
|
* in the first place >:-P}),
|
|
* I was forced to base this driver on reverse engineering
|
|
* (3 weeks' worth of evenings filled with driver work).
|
|
* (and no, I did NOT go the easy way: to pick up a PCI128 for 9 Euros)
|
|
*
|
|
* The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
|
|
* for compatibility reasons) has the following features:
|
|
*
|
|
* - builtin AC97 conformant codec (SNR over 80dB)
|
|
* (really AC97 compliant?? I really doubt it when looking
|
|
* at the mixer register layout)
|
|
* - builtin genuine OPL3
|
|
* - full duplex 16bit playback/record at independent sampling rate
|
|
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
|
|
* - game port (legacy address support)
|
|
* - built-in General DirectX timer having a 20 bits counter
|
|
* with 1us resolution (see below!)
|
|
* - I2S serial 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?)
|
|
* - 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,
|
|
* since it additionally supports the card's 1MHz DirectX timer - just try
|
|
* the following snd-seq module parameters etc.:
|
|
* - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
|
|
* seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
|
|
* seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
|
|
* - "timidity -iAv -B2,8 -Os -EFreverb=0"
|
|
* - "pmidi -p 128:0 jazz.mid"
|
|
*
|
|
* 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.
|
|
* Overview (PCI ID/PCI subID/PCI rev.):
|
|
* - no DMA crackling on SiS735: 0x50DC/0x1801/16
|
|
* - unknown performance: 0x50DC/0x1801/10
|
|
* (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
|
|
*
|
|
* Crackling happens with VIA chipsets or, in my case, an SiS735, which is
|
|
* supposed to be very fast and supposed to get rid of crackling much
|
|
* better than a VIA, yet ironically I still get crackling, like many other
|
|
* people with the same chipset.
|
|
* Possible remedies:
|
|
* - 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
|
|
* - upgrade or downgrade BIOS
|
|
* - 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
|
|
*
|
|
* TODO
|
|
* - test MPU401 MIDI playback etc.
|
|
* - power management. See e.g. intel8x0 or cs4281.
|
|
* This would be nice since the chip runs a bit hot, and it's *required*
|
|
* anyway for proper ACPI power management.
|
|
* - figure out what all unknown port bits are responsible for
