- *
- * Special thanks to David C. Niemi
- *
- *
- * 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
- * 06.05.1998 0.1 Initial release
- * 10.05.1998 0.2 Fixed many bugs, esp. ADC rate calculation
- * First stab at a simple midi interface (no bells&whistles)
- * 13.05.1998 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
- * set_dac_rate in the FMODE_WRITE case in sv_open
- * Fix hwptr out of bounds (now mpg123 works)
- * 14.05.1998 0.4 Don't allow excessive interrupt rates
- * 08.06.1998 0.5 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.6 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.7 Fix realplayer problems - dac.count issues
- * 10.12.1998 0.8 Fix drain_dac trying to wait on not yet initialized DMA
- * 16.12.1998 0.9 Fix a few f_file & FMODE_ bugs
- * 06.01.1999 0.10 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 05.04.1999 0.13 added code to sv_read and sv_write which should detect
- * lockups of the sound chip and revive it. This is basically
- * an ugly hack, but at least applications using this driver
- * won't hang forever. I don't know why these lockups happen,
- * it might well be the motherboard chipset (an early 486 PCI
- * board with ALI chipset), since every busmastering 100MB
- * ethernet card I've tried (Realtek 8139 and Macronix tulip clone)
- * exhibit similar behaviour (they work for a couple of packets
- * and then lock up and can be revived by ifconfig down/up).
- * 07.04.1999 0.14 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Note: dmaio hack might still be wrong on archs other than i386
- * 15.06.1999 0.15 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.16 Add pci_set_master
- * 03.08.1999 0.17 adapt to Linus' new __setup/__initcall
- * added kernel command line options "sonicvibes=reverb" and "sonicvibesdmaio=dmaioaddr"
- * 12.08.1999 0.18 module_init/__setup fixes
- * 24.08.1999 0.19 get rid of the dmaio kludge, replace with allocate_resource
- * 31.08.1999 0.20 add spin_lock_init
- * use new resource allocation to allocate DDMA IO space
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.21 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 28.10.1999 0.22 More waitqueue races fixed
- * 01.12.1999 0.23 New argument to allocate_resource
- * 07.12.1999 0.24 More allocate_resource semantics change
- * 08.01.2000 0.25 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * use Martin Mares' pci_assign_resource
- * 07.02.2000 0.26 Use pci_alloc_consistent and pci_register_driver
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.28 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 31.01.2001 0.29 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 18.05.2001 0.30 PCI probing and error values cleaned up by Marcus
- * Meissner <mm@caldera.de>
- * 03.01.2003 0.31 open_mode fixes from Georg Acher <acher@in.tum.de>
