Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * 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.
+ * 0.19a Added Support for Audigy Cards
+ * Real fix for kernel with highmem support (cast dma_handle to u32).
+ * Fix recording buffering parameters calculation.
+ * Use unsigned long for variables in bit ops.
+ * 0.20a Fixed recording startup
+ * Fixed timer rate setting (it's a 16-bit register)
+ * 0.21 Converted code to use pci_name() instead of accessing slot_name
+ * directly (Eugene Teo)

+ To over come this, samples are copied into the tram and a special dsp patch copies
+ the samples out and generates interrupts when a block has finnished playing.
+

+
+ Creative fixed the sample rate convert problem in emu10k1 rev 7 and higher
+ (including the emu10k2 (audigy)). This allows us to use the regular, and much simpler
+ playback method.
+
+
+ In both methods, dsp code is used to mux audio and passthrough. This ensures that the spdif
+ doesn't receive audio and pasthrough data at the same time. The spdif flag SPCS_NOTAUDIODATA
