Niemi, Jan Pfeifer * * * Module command line parameters: * none so far * * * Supported devices: * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible * /dev/midi simple MIDI UART interface, no ioctl * * The card has both an FM and a Wavetable synth, but I have to figure * out first how to drive them... * * Revision history * 06.05.98 0.1 Initial release * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation * First stab at a simple midi interface (no bells&whistles) * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of * set_dac_rate in the FMODE_WRITE case in cm_open * Fix hwptr out of bounds (now mpg123 works) * 14.05.98 0.4 Don't allow excessive interrupt rates * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice * 03.08.98 0.6 Do not include modversions.h * Now mixer behaviour can basically be selected between * "OSS documented" and "OSS actual" behaviour * 31.08.98 0.7 Fix realplayer problems - dac.count issues * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs * 06.01.99 0.10 remove the silly SA_INTERRUPT flag. * hopefully killed the egcs section type conflict * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl. * reported by Johan Maes <joma@telindus.be> * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK * read/write cannot be executed * 18.08.99 1.5 Only deallocate DMA buffer when unloading. * 02.09.99 1.6 Enable SPDIF LOOP * Change the mixer read back * 21.09.99 2.33 Use RCS version as driver version. * Add support for modem, S/PDIF loop and 4 channels. * (8738 only) * Fix bug cause x11amp cannot play. * * Fixes: * Arnaldo Carvalho de Melo <acme@conectiva.com.br> * 18/05/2001 - .bss nitpicks, fix a bug in set_dac_channels where it * was calling prog_dmabuf with s->lock held, call missing * unlock_kernel in cm_midi_release * 08/10/2001 - use set_current_state in some more places * * Carlos Eduardo Gorges <carlos@techlinux.com.br> * Fri May 25 2001 * - SMP support ( spin[un]lock* revision ) * - speaker mixer support * Mon Aug 13 2001 * - optimizations and cleanups * 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de> * */ /*****************************************************************************/ #include <linux/version.h> #include <linux/config.h> #include <linux/module.h>
