Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 24 | * NOTES |
| 25 | * |
| 26 | * Since Avance does not provide any meaningful documentation, and I |
| 27 | * bought an ALS4000 based soundcard, I was forced to base this driver |
| 28 | * on reverse engineering. |
| 29 | * |
Andreas Mohr | cb780cd | 2008-08-21 21:55:57 +0200 | [diff] [blame] | 30 | * Note: this is no longer true (thank you!): |
| 31 | * pretty verbose chip docu (ALS4000a.PDF) can be found on the ALSA web site. |
| 32 | * Page numbers stated anywhere below with the "SPECS_PAGE:" tag |
| 33 | * refer to: ALS4000a.PDF specs Ver 1.0, May 28th, 1998. |

| 35 | * The ALS4000 seems to be the PCI-cousin of the ALS100. It contains an |
| 36 | * ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport |
| 37 | * interface. These subsystems can be mapped into ISA io-port space, |
| 38 | * using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ |
| 39 | * services to the subsystems. |
| 40 | * |
| 41 | * While ALS4000 is very similar to a SoundBlaster, the differences in |
| 42 | * DMA and capturing require more changes to the SoundBlaster than |
| 43 | * desirable, so I made this separate driver. |
| 44 | * |
| 45 | * The ALS4000 can do real full duplex playback/capture. |
| 46 | * |
| 47 | * FMDAC: |
| 48 | * - 0x4f -> port 0x14 |
| 49 | * - port 0x15 |= 1 |
| 50 | * |
| 51 | * Enable/disable 3D sound: |
| 52 | * - 0x50 -> port 0x14 |
| 53 | * - change bit 6 (0x40) of port 0x15 |
| 54 | * |
| 55 | * Set QSound: |
| 56 | * - 0xdb -> port 0x14 |
| 57 | * - set port 0x15: |
| 58 | * 0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0) |
| 59 | * |
| 60 | * Set KSound: |
| 61 | * - value -> some port 0x0c0d |
| 62 | * |
Andreas Mohr | ba7301c | 2005-11-17 11:03:31 +0100 | [diff] [blame] | 63 | * ToDo: |
Andreas Mohr | c087444 | 2008-08-20 10:04:56 +0200 | [diff] [blame] | 64 | * - by default, don't enable legacy game and use PCI game I/O |
Andreas Mohr | ba7301c | 2005-11-17 11:03:31 +0100 | [diff] [blame] | 65 | * - power management? (card can do voice wakeup according to datasheet!!) |
