2 * azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
3 * Copyright (C) 2002, 2005, 2006, 2007 by Andreas Mohr <andi AT lisas.de>
4 *
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).
36 * (and no, I did NOT go the easy way: to pick up a SB PCI128 for 9 Euros)
37 *
38 * The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
39 * for compatibility reasons) has the following features:
40 *
41 * - builtin AC97 conformant codec (SNR over 80dB)
42 * Note that "conformant" != "compliant"!! this chip's mixer register layout
43 * *differs* from the standard AC97 layout:
44 * they chose to not implement the headphone register (which is not a
45 * problem since it's merely optional), yet when doing this, they committed
46 * the grave sin of letting other registers follow immediately instead of
47 * keeping a headphone dummy register, thereby shifting the mixer register
48 * addresses illegally. So far unfortunately it looks like the very flexible
49 * ALSA AC97 support is still not enough to easily compensate for such a
50 * grave layout violation despite all tweaks and quirks mechanisms it offers.
51 * - builtin genuine OPL3
52 * - full duplex 16bit playback/record at independent sampling rate
53 * - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
54 * - game port (legacy address support)
55 * - builtin 3D enhancement (said to be YAMAHA Ymersion)
56 * - builtin DirectInput support, helps reduce CPU overhead (interrupt-driven
57 * features supported)
58 * - built-in General DirectX timer having a 20 bits counter
59 * with 1us resolution (see below!)
60 * - I2S serial port for external DAC
61 * - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
62 * - supports hardware volume control
63 * - single chip low cost solution (128 pin QFP)
64 * - supports programmable Sub-vendor and Sub-system ID
65 * required for Microsoft's logo compliance (FIXME: where?)
66 * - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
67 *
68 * Note that this driver now is actually *better* than the Windows driver,
69 * since it additionally supports the card's 1MHz DirectX timer - just try
70 * the following snd-seq module parameters etc.:
71 * - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
72 * seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
73 * seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
74 * - "timidity -iAv -B2,8 -Os -EFreverb=0"
75 * - "pmidi -p 128:0 jazz.mid"
76 *
77 * Certain PCI versions of this card are susceptible to DMA traffic underruns
78 * in some systems (resulting in sound crackling/clicking/popping),
79 * probably because they don't have a DMA FIFO buffer or so.
80 * Overview (PCI ID/PCI subID/PCI rev.):
81 * - no DMA crackling on SiS735: 0x50DC/0x1801/16
82 * - unknown performance: 0x50DC/0x1801/10
83 * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
84 *
85 * Crackling happens with VIA chipsets or, in my case, an SiS735, which is
86 * supposed to be very fast and supposed to get rid of crackling much
87 * better than a VIA, yet ironically I still get crackling, like many other
88 * people with the same chipset.
89 * Possible remedies:
90 * - plug card into a different PCI slot, preferrably one that isn't shared
91 * too much (this helps a lot, but not completely!)
92 * - get rid of PCI VGA card, use AGP instead
93 * - upgrade or downgrade BIOS
94 * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
95 * Not too helpful.
96 * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
97 *
98 * BUGS
99 * - full-duplex might *still* be problematic, not fully tested recently
100 * - (non-bug) "Bass/Treble or 3D settings don't work" - they do get evaluated
101 * if you set PCM output switch to "pre 3D" instead of "post 3D".
102 * If this can't be set, then get a mixer application that Isn't Stupid (tm)
103 * (e.g. kmix, gamix) - unfortunately several are!!
104 *
105 * TODO
106 * - test MPU401 MIDI playback etc.
107 * - add some power micro-management (disable various units of the card
108 * as long as they're unused). However this requires I/O ports which I
109 * haven't figured out yet and which thus might not even exist...
110 * The standard suspend/resume functionality could probably make use of
111 * some improvement, too...
112 * - figure out what all unknown port bits are responsible for
113 * - figure out some cleverly evil scheme to possibly make ALSA AC97 code
114 * fully accept our quite incompatible ""AC97"" mixer and thus save some
115 * code (but I'm not too optimistic that doing this is possible at all)
