2 | * linux/sound/oss/dmasound/dmasound_awacs.c | |
3 | * | |
4 | * PowerMac `AWACS' and `Burgundy' DMA Sound Driver | |
5 | * with some limited support for DACA & Tumbler | |
6 | * | |
7 | * See linux/sound/oss/dmasound/dmasound_core.c for copyright and | |
8 | * history prior to 2001/01/26. | |
9 | * | |
10 | * 26/01/2001 ed 0.1 Iain Sandoe | |
11 | * - added version info. | |
12 | * - moved dbdma command buffer allocation to PMacXXXSqSetup() | |
13 | * - fixed up beep dbdma cmd buffers | |
14 | * | |
15 | * 08/02/2001 [0.2] | |
16 | * - make SNDCTL_DSP_GETFMTS return the correct info for the h/w | |
17 | * - move soft format translations to a separate file | |
18 | * - [0.3] make SNDCTL_DSP_GETCAPS return correct info. | |
19 | * - [0.4] more informative machine name strings. | |
20 | * - [0.5] | |
21 | * - record changes. | |
22 | * - made the default_hard/soft entries. | |
23 | * 04/04/2001 [0.6] | |
24 | * - minor correction to bit assignments in awacs_defs.h | |
25 | * - incorporate mixer changes from 2.2.x back-port. | |
26 | * - take out passthru as a rec input (it isn't). | |
27 | * - make Input Gain slider work the 'right way up'. | |
28 | * - try to make the mixer sliders more logical - so now the | |
29 | * input selectors are just two-state (>50% == ON) and the | |
30 | * Input Gain slider handles the rest of the gain issues. | |
31 | * - try to pick slider representations that most closely match | |
32 | * the actual use - e.g. IGain for input gain... | |
33 | * - first stab at over/under-run detection. | |
34 | * - minor cosmetic changes to IRQ identification. | |
35 | * - fix bug where rates > max would be reported as supported. | |
36 | * - first stab at over/under-run detection. | |
37 | * - make use of i2c for mixer settings conditional on perch | |
38 | * rather than cuda (some machines without perch have cuda). | |
39 | * - fix bug where TX stops when dbdma status comes up "DEAD" | |
40 | * so far only reported on PowerComputing clones ... but. | |
41 | * - put in AWACS/Screamer register write timeouts. | |
42 | * - part way to partitioning the init() stuff | |
43 | * - first pass at 'tumbler' stuff (not support - just an attempt | |
44 | * to allow the driver to load on new G4s). | |
45 | * 01/02/2002 [0.7] - BenH | |
46 | * - all sort of minor bits went in since the latest update, I | |
47 | * bumped the version number for that reason | |
48 | * | |
49 | * 07/26/2002 [0.8] - BenH | |
50 | * - More minor bits since last changelog (I should be more careful | |
51 | * with those) | |
52 | * - Support for snapper & better tumbler integration by Toby Sargeant | |
53 | * - Headphone detect for scremer by Julien Blache | |
54 | * - More tumbler fixed by Andreas Schwab | |
55 | * 11/29/2003 [0.8.1] - Renzo Davoli (King Enzo) | |
56 | * - Support for Snapper line in | |
57 | * - snapper input resampling (for rates < 44100) | |
58 | * - software line gain control | |
