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

Linus Torvalds1da177e2005-04-16 15:20:36 -07004 *
5 * Framework borrowed from Bart Hartgers's als4000.c.
6 * Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
7 * found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
8 * Other versions are:
9 * PCI168 A(W), sub ID 1800
10 * PCI168 A/AP, sub ID 8000
11 * Please give me feedback in case you try my driver with one of these!!

28 * NOTES
29 * Since Aztech does not provide any chipset documentation,
30 * even on repeated request to various addresses,
31 * and the answer that was finally given was negative
32 * (and I was stupid enough to manage to get hold of a PCI168 soundcard
33 * in the first place >:-P}),
34 * I was forced to base this driver on reverse engineering
35 * (3 weeks' worth of evenings filled with driver work).
Andreas Mohre2f87262006-05-17 11:04:19 +020036 * (and no, I did NOT go the easy way: to pick up a SB PCI128 for 9 Euros)
Linus Torvalds1da177e2005-04-16 15:20:36 -070037 *
Andreas Mohr02330fb2008-05-16 12:18:29 +020038 * It is quite likely that the AZF3328 chip is the PCI cousin of the
39 * AZF3318 ("azt1020 pnp", "MM Pro 16") ISA chip, given very similar specs.
Linus Torvalds1da177e2005-04-16 15:20:36 -070040 *
Andreas Mohr02330fb2008-05-16 12:18:29 +020041 * The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
42 * for compatibility reasons) from Azfin (joint-venture of Aztech and Fincitec,
43 * Fincitec acquired by National Semiconductor in 2002, together with the
44 * Fincitec-related company ARSmikro) has the following features:
45 *
46 * - compatibility & compliance:
47 * - Microsoft PC 97 ("PC 97 Hardware Design Guide",
48 * http://www.microsoft.com/whdc/archive/pcguides.mspx)
49 * - Microsoft PC 98 Baseline Audio
50 * - MPU401 UART
51 * - Sound Blaster Emulation (DOS Box)
Linus Torvalds1da177e2005-04-16 15:20:36 -070052 * - builtin AC97 conformant codec (SNR over 80dB)
Andreas Mohr13769e32006-05-17 11:03:16 +020053 * Note that "conformant" != "compliant"!! this chip's mixer register layout
54 * *differs* from the standard AC97 layout:
55 * they chose to not implement the headphone register (which is not a
56 * problem since it's merely optional), yet when doing this, they committed
57 * the grave sin of letting other registers follow immediately instead of
58 * keeping a headphone dummy register, thereby shifting the mixer register
59 * addresses illegally. So far unfortunately it looks like the very flexible
60 * ALSA AC97 support is still not enough to easily compensate for such a
61 * grave layout violation despite all tweaks and quirks mechanisms it offers.
Andreas Mohr02330fb2008-05-16 12:18:29 +020062 * - builtin genuine OPL3 - verified to work fine, 20080506
Linus Torvalds1da177e2005-04-16 15:20:36 -070063 * - full duplex 16bit playback/record at independent sampling rate
Andreas Mohr02330fb2008-05-16 12:18:29 +020064 * - MPU401 (+ legacy address support, claimed by one official spec sheet)
65 * FIXME: how to enable legacy addr??
Linus Torvalds1da177e2005-04-16 15:20:36 -070066 * - game port (legacy address support)
Andreas Mohre24a1212007-03-26 12:49:45 +020067 * - builtin DirectInput support, helps reduce CPU overhead (interrupt-driven
Andreas Mohr02330fb2008-05-16 12:18:29 +020068 * features supported). - See common term "Digital Enhanced Game Port"...
69 * (probably DirectInput 3.0 spec - confirm)
70 * - builtin 3D enhancement (said to be YAMAHA Ymersion)
Linus Torvalds1da177e2005-04-16 15:20:36 -070071 * - built-in General DirectX timer having a 20 bits counter
Andreas Mohrd91c64c2005-10-25 11:17:45 +020072 * with 1us resolution (see below!)
Andreas Mohr02330fb2008-05-16 12:18:29 +020073 * - I2S serial output port for external DAC
Linus Torvalds1da177e2005-04-16 15:20:36 -070074 * - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
75 * - supports hardware volume control
76 * - single chip low cost solution (128 pin QFP)
77 * - supports programmable Sub-vendor and Sub-system ID
78 * required for Microsoft's logo compliance (FIXME: where?)
Andreas Mohr02330fb2008-05-16 12:18:29 +020079 * At least the Trident 4D Wave DX has one bit somewhere
80 * to enable writes to PCI subsystem VID registers, that should be it.
81 * This might easily be in extended PCI reg space, since PCI168 also has
82 * some custom data starting at 0x80. What kind of config settings
83 * are located in our extended PCI space anyway??
Linus Torvalds1da177e2005-04-16 15:20:36 -070084 * - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
85 *
Andreas Mohrd91c64c2005-10-25 11:17:45 +020086 * Note that this driver now is actually *better* than the Windows driver,
87 * since it additionally supports the card's 1MHz DirectX timer - just try
88 * the following snd-seq module parameters etc.:
89 * - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
90 * seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
91 * seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
92 * - "timidity -iAv -B2,8 -Os -EFreverb=0"
93 * - "pmidi -p 128:0 jazz.mid"
94 *
Andreas Mohr02330fb2008-05-16 12:18:29 +020095 * OPL3 hardware playback testing, try something like:
96 * cat /proc/asound/hwdep
97 * and
98 * aconnect -o
99 * Then use
100 * sbiload -Dhw:x,y --opl3 /usr/share/sounds/opl3/std.o3 ......./drums.o3
101 * where x,y is the xx-yy number as given in hwdep.
102 * Then try
103 * pmidi -p a:b jazz.mid
104 * where a:b is the client number plus 0 usually, as given by aconnect above.
105 * Oh, and make sure to unmute the FM mixer control (doh!)
106 * NOTE: power use during OPL3 playback is _VERY_ high (70W --> 90W!)
107 * despite no CPU activity, possibly due to hindering ACPI idling somehow.
108 * Shouldn't be a problem of the AZF3328 chip itself, I'd hope.
109 * Higher PCM / FM mixer levels seem to conflict (causes crackling),
110 * at least sometimes. Maybe even use with hardware sequencer timer above :)
111 * adplay/adplug-utils might soon offer hardware-based OPL3 playback, too.
112 *
Linus Torvalds1da177e2005-04-16 15:20:36 -0700113 * Certain PCI versions of this card are susceptible to DMA traffic underruns
114 * in some systems (resulting in sound crackling/clicking/popping),
115 * probably because they don't have a DMA FIFO buffer or so.
116 * Overview (PCI ID/PCI subID/PCI rev.):
117 * - no DMA crackling on SiS735: 0x50DC/0x1801/16
118 * - unknown performance: 0x50DC/0x1801/10
Andreas Mohrd91c64c2005-10-25 11:17:45 +0200119 * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
120 *
Linus Torvalds1da177e2005-04-16 15:20:36 -0700121 * Crackling happens with VIA chipsets or, in my case, an SiS735, which is
122 * supposed to be very fast and supposed to get rid of crackling much
123 * better than a VIA, yet ironically I still get crackling, like many other
124 * people with the same chipset.
125 * Possible remedies:
Andreas Mohr02330fb2008-05-16 12:18:29 +0200126 * - use speaker (amplifier) output instead of headphone output
127 * (in case crackling is due to overloaded output clipping)
Linus Torvalds1da177e2005-04-16 15:20:36 -0700128 * - plug card into a different PCI slot, preferrably one that isn't shared
129 * too much (this helps a lot, but not completely!)
130 * - get rid of PCI VGA card, use AGP instead
131 * - upgrade or downgrade BIOS
132 * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
133 * Not too helpful.
134 * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
Andreas Mohr02330fb2008-05-16 12:18:29 +0200135 *
Linus Torvalds1da177e2005-04-16 15:20:36 -0700136 * BUGS
Andreas Mohr02330fb2008-05-16 12:18:29 +0200137 * - full-duplex might *still* be problematic, however a recent test was fine
Andreas Mohre24a1212007-03-26 12:49:45 +0200138 * - (non-bug) "Bass/Treble or 3D settings don't work" - they do get evaluated
139 * if you set PCM output switch to "pre 3D" instead of "post 3D".
140 * If this can't be set, then get a mixer application that Isn't Stupid (tm)
141 * (e.g. kmix, gamix) - unfortunately several are!!
Andreas Mohr02330fb2008-05-16 12:18:29 +0200142 * - locking is not entirely clean, especially the audio stream activity
143 * ints --> may be racy
144 * - an _unconnected_ secondary joystick at the gameport will be reported
145 * to be "active" (floating values, not precisely -1) due to the way we need
146 * to read the Digital Enhanced Game Port. Not sure whether it is fixable.
147 *
Linus Torvalds1da177e2005-04-16 15:20:36 -0700148 * TODO
149 * - test MPU401 MIDI playback etc.
Andreas Mohr02330fb2008-05-16 12:18:29 +0200150 * - add more power micro-management (disable various units of the card
151 * as long as they're unused). However this requires more I/O ports which I
Andreas Mohrca54bde2006-05-17 11:02:24 +0200152 * haven't figured out yet and which thus might not even exist...
153 * The standard suspend/resume functionality could probably make use of
154 * some improvement, too...
Linus Torvalds1da177e2005-04-16 15:20:36 -0700155 * - figure out what all unknown port bits are responsible for
Andreas Mohr13769e32006-05-17 11:03:16 +0200156 * - figure out some cleverly evil scheme to possibly make ALSA AC97 code
157 * fully accept our quite incompatible ""AC97"" mixer and thus save some
158 * code (but I'm not too optimistic that doing this is possible at all)
Andreas Mohr02330fb2008-05-16 12:18:29 +0200159 * - use MMIO (memory-mapped I/O)? Slightly faster access, e.g. for gameport.
