3 * Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
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 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 * (really AC97 compliant?? I really doubt it when looking
43 * at the mixer register layout)
44 * - builtin genuine OPL3
45 * - full duplex 16bit playback/record at independent sampling rate
46 * - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
47 * - game port (legacy address support)
48 * - built-in General DirectX timer having a 20 bits counter
49 * with 1us resolution (FIXME: where is it?)
50 * - I2S serial port for external DAC
51 * - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
52 * - supports hardware volume control
53 * - single chip low cost solution (128 pin QFP)
54 * - supports programmable Sub-vendor and Sub-system ID
55 * required for Microsoft's logo compliance (FIXME: where?)
56 * - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
57 *
58 * Certain PCI versions of this card are susceptible to DMA traffic underruns
59 * in some systems (resulting in sound crackling/clicking/popping),
60 * probably because they don't have a DMA FIFO buffer or so.
61 * Overview (PCI ID/PCI subID/PCI rev.):
62 * - no DMA crackling on SiS735: 0x50DC/0x1801/16
63 * - unknown performance: 0x50DC/0x1801/10
64 *
65 * Crackling happens with VIA chipsets or, in my case, an SiS735, which is
66 * supposed to be very fast and supposed to get rid of crackling much
67 * better than a VIA, yet ironically I still get crackling, like many other
68 * people with the same chipset.
69 * Possible remedies:
70 * - plug card into a different PCI slot, preferrably one that isn't shared
71 * too much (this helps a lot, but not completely!)
72 * - get rid of PCI VGA card, use AGP instead
73 * - upgrade or downgrade BIOS
74 * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
75 * Not too helpful.
76 * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
77 *
78 * BUGS
79 * - when Ctrl-C'ing mpg321, the playback loops a bit
80 * (premature DMA playback reset?)
81 * - full-duplex sometimes breaks (IRQ management issues?).
82 * Once even a spontaneous REBOOT happened!!!
83 *
84 * TODO
85 * - test MPU401 MIDI playback etc.
86 * - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
87 * This would be nice since the chip runs a bit hot, and it's *required*
88 * anyway for proper ACPI power management. In other words: rest
89 * assured that I *will* implement this very soon; as soon as Linux 2.5.x
90 * has power management that's bugfree enough to work properly on my desktop.
91 * - figure out what all unknown port bits are responsible for
