*
* 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>
