| * azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168). |
| * Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com> |
| * |
| * 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 (FIXME: where is it?) |
| * - 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 |
| * |
| * 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 |
| * |
| * 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 |
| * - when Ctrl-C'ing mpg321, the playback loops a bit |
| * (premature DMA playback reset?) |
| * - full-duplex sometimes breaks (IRQ management issues?). |
| * Once even a spontaneous REBOOT happened!!! |
| * |
| * TODO |
| * - test MPU401 MIDI playback etc. |
| * - power management (CONFIG_PM). 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. In other words: rest |
| * assured that I *will* implement this very soon; as soon as Linux 2.5.x |
| * has power management that's bugfree enough to work properly on my desktop. |
| * - figure out what all unknown port bits are responsible for |
