| 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 Mohr | e2f8726 | 2006-05-17 11:04:19 +0200 | [diff] [blame] | 36 | * (and no, I did NOT go the easy way: to pick up a SB PCI128 for 9 Euros) |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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) |
Andreas Mohr | 13769e3 | 2006-05-17 11:03:16 +0200 | [diff] [blame] | 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. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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 | * - built-in General DirectX timer having a 20 bits counter |
Andreas Mohr | d91c64c | 2005-10-25 11:17:45 +0200 | [diff] [blame] | 56 | * with 1us resolution (see below!) |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 57 | * - I2S serial port for external DAC |
| 58 | * - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI |
| 59 | * - supports hardware volume control |
| 60 | * - single chip low cost solution (128 pin QFP) |
| 61 | * - supports programmable Sub-vendor and Sub-system ID |
| 62 | * required for Microsoft's logo compliance (FIXME: where?) |
| 63 | * - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms |
| 64 | * |
Andreas Mohr | d91c64c | 2005-10-25 11:17:45 +0200 | [diff] [blame] | 65 | * Note that this driver now is actually *better* than the Windows driver, |
| 66 | * since it additionally supports the card's 1MHz DirectX timer - just try |
| 67 | * the following snd-seq module parameters etc.: |
| 68 | * - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0 |
| 69 | * seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0 |
| 70 | * seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000 |
| 71 | * - "timidity -iAv -B2,8 -Os -EFreverb=0" |
| 72 | * - "pmidi -p 128:0 jazz.mid" |
| 73 | * |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 74 | * Certain PCI versions of this card are susceptible to DMA traffic underruns |
| 75 | * in some systems (resulting in sound crackling/clicking/popping), |
| 76 | * probably because they don't have a DMA FIFO buffer or so. |
| 77 | * Overview (PCI ID/PCI subID/PCI rev.): |
| 78 | * - no DMA crackling on SiS735: 0x50DC/0x1801/16 |
| 79 | * - unknown performance: 0x50DC/0x1801/10 |
Andreas Mohr | d91c64c | 2005-10-25 11:17:45 +0200 | [diff] [blame] | 80 | * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler) |
| 81 | * |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 82 | * Crackling happens with VIA chipsets or, in my case, an SiS735, which is |
| 83 | * supposed to be very fast and supposed to get rid of crackling much |
| 84 | * better than a VIA, yet ironically I still get crackling, like many other |
| 85 | * people with the same chipset. |
| 86 | * Possible remedies: |
| 87 | * - plug card into a different PCI slot, preferrably one that isn't shared |
| 88 | * too much (this helps a lot, but not completely!) |
| 89 | * - get rid of PCI VGA card, use AGP instead |
| 90 | * - upgrade or downgrade BIOS |
| 91 | * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX) |
| 92 | * Not too helpful. |
| 93 | * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS |
| 94 | * |
| 95 | * BUGS |
Andreas Mohr | d91c64c | 2005-10-25 11:17:45 +0200 | [diff] [blame] | 96 | * - full-duplex might *still* be problematic, not fully tested recently |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 97 | * |
| 98 | * TODO |
| 99 | * - test MPU401 MIDI playback etc. |
Andreas Mohr | ca54bde | 2006-05-17 11:02:24 +0200 | [diff] [blame] | 100 | * - add some power micro-management (disable various units of the card |
| 101 | * as long as they're unused). However this requires I/O ports which I |
| 102 | * haven't figured out yet and which thus might not even exist... |
| 103 | * The standard suspend/resume functionality could probably make use of |
| 104 | * some improvement, too... |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 105 | * - figure out what all unknown port bits are responsible for |
Andreas Mohr | 13769e3 | 2006-05-17 11:03:16 +0200 | [diff] [blame] | 106 | * - figure out some cleverly evil scheme to possibly make ALSA AC97 code |
| 107 | * fully accept our quite incompatible ""AC97"" mixer and thus save some |
| 108 | * code (but I'm not too optimistic that doing this is possible at all) |
