- * 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
- *
- *  Revision history
- *    10.11.1998   0.1   Initial release (without any hardware)
- *    22.03.1999   0.2   cinfo.blocks should be reset after GETxPTR ioctl.
- *                       reported by Johan Maes <joma@telindus.be>
- *                       return EAGAIN instead of EBUSY when O_NONBLOCK
- *                       read/write cannot be executed
- *    07.04.1999   0.3   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>
- *    15.06.1999   0.4   Fix bad allocation bug.
- *                       Thanks to Deti Fliegl <fliegl@in.tum.de>
- *    28.06.1999   0.5   Add pci_set_master
- *    12.08.1999   0.6   Fix MIDI UART crashing the driver
- *                       Changed mixer semantics from OSS documented
- *                       behaviour to OSS "code behaviour".
- *                       Recording might actually work now.
- *                       The real DDMA controller address register is at PCI config
- *                       0x60, while the register at 0x18 is used as a placeholder
- *                       register for BIOS address allocation. This register
- *                       is supposed to be copied into 0x60, according
- *                       to the Solo1 datasheet. When I do that, I can access
- *                       the DDMA registers except the mask bit, which
- *                       is stuck at 1. When I copy the contents of 0x18 +0x10
- *                       to the DDMA base register, everything seems to work.
- *                       The fun part is that the Windows Solo1 driver doesn't
- *                       seem to do these tricks.
- *                       Bugs remaining: plops and clicks when starting/stopping playback
- *    31.08.1999   0.7   add spin_lock_init
- *                       replaced current->state = x with set_current_state(x)
- *    03.09.1999   0.8   change read semantics for MIDI to match
- *                       OSS more closely; remove possible wakeup race
- *    07.10.1999   0.9   Fix initialization; complain if sequencer writes time out
- *                       Revised resource grabbing for the FM synthesizer
- *    28.10.1999   0.10  More waitqueue races fixed
- *    09.12.1999   0.11  Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M)
- *                       Disabling recording on Alpha
- *    12.01.2000   0.12  Prevent some ioctl's from returning bad count values on underrun/overrun;
- *                       Tim Janik's BSE (Bedevilled Sound Engine) found this
- *                       Integrated (aka redid 8-)) APM support patch by Zach Brown
- *    07.02.2000   0.13  Use pci_alloc_consistent and pci_register_driver
- *    19.02.2000   0.14  Use pci_dma_supported to determine if recording should be disabled
- *    13.03.2000   0.15  Reintroduce initialization of a couple of PCI config space registers
- *    21.11.2000   0.16  Initialize dma buffers in poll, otherwise poll may return a bogus mask
- *    12.12.2000   0.17  More dma buffer initializations, patch from
- *                       Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- *    31.01.2001   0.18  Register/Unregister gameport, original patch from
- *                       Nathaniel Daw <daw@cs.cmu.edu>
- *                       Fix SETTRIGGER non OSS API conformity
- *    10.03.2001         provide abs function, prevent picking up a bogus kernel macro
- *                       for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
- *    15.05.2001         pci_enable_device moved, return values in probe cleaned
- *                       up. Marcus Meissner <mm@caldera.de>
- *    22.05.2001   0.19  more cleanups, changed PM to PCI 2.4 style, got rid
- *                       of global list of devices, using pci device data.
- *                       Marcus Meissner <mm@caldera.de>
- *    03.01.2003   0.20  open_mode fixes from Georg Acher <acher@in.tum.de>
