- *
- * Supported devices:
- * /dev/dsp: Standard /dev/dsp device, OSS-compatible
- * /dev/dsp1: Routes to rear speakers only
- * /dev/mixer: Standard /dev/mixer device, OSS-compatible
- * /dev/midi: Raw MIDI UART device, mostly OSS-compatible
- * /dev/sequencer: Sequencer Interface (requires sound.o)
- *
- * Revision history:
- * 0.1 beta Initial release
- * 0.2 Lowered initial mixer vol. Improved on stuttering wave playback. Added MIDI UART support.
- * 0.3 Fixed mixer routing bug, added APS, joystick support.
- * 0.4 Added rear-channel, SPDIF support.
- * 0.5 Source cleanup, SMP fixes, multiopen support, 64 bit arch fixes,
- * moved bh's to tasklets, moved to the new PCI driver initialization style.
- * 0.6 Make use of pci_alloc_consistent, improve compatibility layer for 2.2 kernels,
- * code reorganization and cleanup.
- * 0.7 Support for the Emu-APS. Bug fixes for voice cache setup, mmaped sound + poll().
- * Support for setting external TRAM size.
- * 0.8 Make use of the kernel ac97 interface. Support for a dsp patch manager.
- * 0.9 Re-enables rear speakers volume controls
- * 0.10 Initializes rear speaker volume.
- * Dynamic patch storage allocation.
- * New private ioctls to change control gpr values.
- * Enable volume control interrupts.
- * By default enable dsp routes to digital out.
- * 0.11 Fixed fx / 4 problem.
- * 0.12 Implemented mmaped for recording.
- * Fixed bug: not unreserving mmaped buffer pages.
- * IRQ handler cleanup.
- * 0.13 Fixed problem with dsp1
- * Simplified dsp patch writing (inside the driver)
- * Fixed several bugs found by the Stanford tools
- * 0.14 New control gpr to oss mixer mapping feature (Chris Purnell)
- * Added AC3 Passthrough Support (Juha Yrjola)
- * Added Support for 5.1 cards (digital out and the third analog out)
- * 0.15 Added Sequencer Support (Daniel Mack)
- * Support for multichannel pcm playback (Eduard Hasenleithner)
- * 0.16 Mixer improvements, added old treble/bass support (Daniel Bertrand)
- * Small code format cleanup.
- * Deadlock bug fix for emu10k1_volxxx_irqhandler().
- * 0.17 Fix for mixer SOUND_MIXER_INFO ioctl.
- * Fix for HIGHMEM machines (emu10k1 can only do 31 bit bus master)
- * midi poll initial implementation.
- * Small mixer fixes/cleanups.
- * Improved support for 5.1 cards.
- * 0.18 Fix for possible leak in pci_alloc_consistent()
- * Cleaned up poll() functions (audio and midi). Don't start input.
- * Restrict DMA pages used to 512Mib range.
- * New AC97_BOOST mixer ioctl.
