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

1027 with the normal dbdma_cmd blocks - we would have to re-write the buffer start
1028 addresses each time. So, we will keep a single dbdma_cmd block which can be
1029 fiddled with.
1030 When DEAD status is first reported the content of the faulted dbdma block is
1031 copied into the emergency buffer and we note that the buffer is in use.
1032 we then bump the start physical address by the amount that was successfully
1033 output before it died.
1034 On any subsequent DEAD result we just do the bump-ups (we know that we are
1035 already using the emergency dbdma_cmd).
1036 CHECK: this just tries to "do it". It is possible that we should abandon
1037 xfers when the number of residual bytes gets below a certain value - I can
1038 see that this might cause a loop-forever if too small a transfer causes
1039 DEAD status. However this is a TODO for now - we'll see what gets reported.
1040 When we get a successful transfer result with the emergency buffer we just
1041 pretend that it completed using the original dmdma_cmd and carry on. The
1042 'next_cmd' field will already point back to the original loop of blocks.
