- *
- * 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>
