  28  *
  29  *  Supported devices:
  30  *  /dev/dsp    standard /dev/dsp device, (mostly) OSS compatible
  31  *  /dev/mixer  standard /dev/mixer device, (mostly) OSS compatible
  32  *  /dev/midi   simple MIDI UART interface, no ioctl
  33  *
  34  *  The card has both an FM and a Wavetable synth, but I have to figure
  35  *  out first how to drive them...
  36  *
  37  *  Revision history
  38  *    06.05.1998   0.1   Initial release
  39  *    10.05.1998   0.2   Fixed many bugs, esp. ADC rate calculation
  40  *                       First stab at a simple midi interface (no bells&whistles)
  41  *    13.05.1998   0.3   Fix stupid cut&paste error: set_adc_rate was called instead of
  42  *                       set_dac_rate in the FMODE_WRITE case in sv_open
  43  *                       Fix hwptr out of bounds (now mpg123 works)
  44  *    14.05.1998   0.4   Don't allow excessive interrupt rates
  45  *    08.06.1998   0.5   First release using Alan Cox' soundcore instead of miscdevice
  46  *    03.08.1998   0.6   Do not include modversions.h
  47  *                       Now mixer behaviour can basically be selected between
  48  *                       "OSS documented" and "OSS actual" behaviour
  49  *    31.08.1998   0.7   Fix realplayer problems - dac.count issues
  50  *    10.12.1998   0.8   Fix drain_dac trying to wait on not yet initialized DMA
  51  *    16.12.1998   0.9   Fix a few f_file & FMODE_ bugs
  52  *    06.01.1999   0.10  remove the silly SA_INTERRUPT flag.
  53  *                       hopefully killed the egcs section type conflict
  54  *    12.03.1999   0.11  cinfo.blocks should be reset after GETxPTR ioctl.
  55  *                       reported by Johan Maes <joma@telindus.be>
  56  *    22.03.1999   0.12  return EAGAIN instead of EBUSY when O_NONBLOCK
  57  *                       read/write cannot be executed
  58  *    05.04.1999   0.13  added code to sv_read and sv_write which should detect
  59  *                       lockups of the sound chip and revive it. This is basically
  60  *                       an ugly hack, but at least applications using this driver
  61  *                       won't hang forever. I don't know why these lockups happen,
  62  *                       it might well be the motherboard chipset (an early 486 PCI
  63  *                       board with ALI chipset), since every busmastering 100MB
  64  *                       ethernet card I've tried (Realtek 8139 and Macronix tulip clone)
  65  *                       exhibit similar behaviour (they work for a couple of packets
  66  *                       and then lock up and can be revived by ifconfig down/up).
  67  *    07.04.1999   0.14  implemented the following ioctl's: SOUND_PCM_READ_RATE,
  68  *                       SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
  69  *                       Alpha fixes reported by Peter Jones <pjones@redhat.com>
  70  *                       Note: dmaio hack might still be wrong on archs other than i386
  71  *    15.06.1999   0.15  Fix bad allocation bug.
  72  *                       Thanks to Deti Fliegl <fliegl@in.tum.de>
  73  *    28.06.1999   0.16  Add pci_set_master
  74  *    03.08.1999   0.17  adapt to Linus' new __setup/__initcall
  75  *                       added kernel command line options "sonicvibes=reverb" and "sonicvibesdmaio=dmaioaddr"
  76  *    12.08.1999   0.18  module_init/__setup fixes
  77  *    24.08.1999   0.19  get rid of the dmaio kludge, replace with allocate_resource
  78  *    31.08.1999   0.20  add spin_lock_init
  79  *                       use new resource allocation to allocate DDMA IO space
  80  *                       replaced current->state = x with set_current_state(x)
  81  *    03.09.1999   0.21  change read semantics for MIDI to match
  82  *                       OSS more closely; remove possible wakeup race
  83  *    28.10.1999   0.22  More waitqueue races fixed
  84  *    01.12.1999   0.23  New argument to allocate_resource
  85  *    07.12.1999   0.24  More allocate_resource semantics change
  86  *    08.01.2000   0.25  Prevent some ioctl's from returning bad count values on underrun/overrun;
  87  *                       Tim Janik's BSE (Bedevilled Sound Engine) found this
  88  *                       use Martin Mares' pci_assign_resource
  89  *    07.02.2000   0.26  Use pci_alloc_consistent and pci_register_driver
  90  *    21.11.2000   0.27  Initialize dma buffers in poll, otherwise poll may return a bogus mask
  91  *    12.12.2000   0.28  More dma buffer initializations, patch from
  92  *                       Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
  93  *    31.01.2001   0.29  Register/Unregister gameport
  94  *                       Fix SETTRIGGER non OSS API conformity
  95  *    18.05.2001   0.30  PCI probing and error values cleaned up by Marcus
  96  *                       Meissner <mm@caldera.de>
