|
*
|
|
* 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!!

|
|
* (XP/Vista do not support this card at all but every Linux distribution
|
|
* has very good support out of the box;
|
|
* just to make sure that the right people hit this and get to know that,
|
|
* despite the high level of Internet ignorance - as usual :-P -
|
|
* about very good support for this card - on Linux!)

|
|
* 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 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) 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:
|
|
* they chose to not implement the headphone register (which is not a
|
|
* problem since it's merely optional), yet when doing this, they committed
|
|
* the grave sin of letting other registers follow immediately instead of
|
|
* keeping a headphone dummy register, thereby shifting the mixer register
|
|
* 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.
|
|
* Well, not quite: now ac97 layer is much improved (bus-specific ops!),
|
|
* thus I was able to implement support - it's actually working quite well.
|
|
* An interesting item might be Aztech AMR 2800-W, since it's an AC97
|
|
* modem card which might reveal the Aztech-specific codec ID which
|
|
* we might want to pretend, too. Dito PCI168's brother, PCI368,
|
|
* where the advertising datasheet says it's AC97-based and has a
|
|
* Digital Enhanced Game Port.
|
|
* - builtin genuine OPL3 - verified to work fine, 20080506
|
|
* - full duplex 16bit playback/record at independent sampling rate
|
|
* - MPU401 (+ legacy address support, claimed by one official spec sheet)
|
|
* FIXME: how to enable legacy addr??
|
|
* - game port (legacy address support)
|
|
* - builtin DirectInput support, helps reduce CPU overhead (interrupt-driven
|
|
* 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 output port for external DAC
|
|
* [FIXME: 3.3V or 5V level? maximum rate is 66.2kHz right?]
|
|
* - 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 [24C02 SEEPROM chip]
|
|
* 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
|
|
* [TDA1517P chip]
|
|
*
|
|
* 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"
|
|
*
|
|
* 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.
|
|
* 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:
|
|
* - use speaker (amplifier) output instead of headphone output
|
|
* (in case crackling is due to overloaded output clipping)
|
|
* - plug card into a different PCI slot, preferably 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, 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
|
|
* - use PCI_VDEVICE
|
|
* - verify driver status on x86_64
|
|
* - test multi-card driver operation
|
|
* - (ab)use 1MHz DirectX timer as kernel clocksource
|
|
* - test MPU401 MIDI playback etc.
|
|
* - add more power micro-management (disable various units of the card
|
|
* as long as they're unused, to improve audio quality and save power).
|
|
* 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 what all unknown port bits are responsible for
|
|
* - 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.

"dump joy200 0x200 8", "dump mpu388 0x388 4", "dump joy 0xb400 8",

possibly within a "while true; do ... sleep 1; done" loop.
