|
*
|
|
* 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>
|
