32 * Module command line parameters:
33 * none so far
34 *
35 *
36 * Supported devices:
37 * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
38 * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
39 * /dev/midi simple MIDI UART interface, no ioctl
40 *
41 * The card has both an FM and a Wavetable synth, but I have to figure
42 * out first how to drive them...
43 *
44 * Revision history
45 * 06.05.98 0.1 Initial release
46 * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation
47 * First stab at a simple midi interface (no bells&whistles)
48 * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
49 * set_dac_rate in the FMODE_WRITE case in cm_open
50 * Fix hwptr out of bounds (now mpg123 works)
51 * 14.05.98 0.4 Don't allow excessive interrupt rates
52 * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice
53 * 03.08.98 0.6 Do not include modversions.h
54 * Now mixer behaviour can basically be selected between
55 * "OSS documented" and "OSS actual" behaviour
56 * 31.08.98 0.7 Fix realplayer problems - dac.count issues
57 * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA
58 * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs
59 * 06.01.99 0.10 remove the silly SA_INTERRUPT flag.
60 * hopefully killed the egcs section type conflict
61 * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
62 * reported by Johan Maes <joma@telindus.be>
63 * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
64 * read/write cannot be executed
65 * 18.08.99 1.5 Only deallocate DMA buffer when unloading.
66 * 02.09.99 1.6 Enable SPDIF LOOP
67 * Change the mixer read back
68 * 21.09.99 2.33 Use RCS version as driver version.
69 * Add support for modem, S/PDIF loop and 4 channels.
70 * (8738 only)
71 * Fix bug cause x11amp cannot play.
