Oof. I just skimmed the Changelogs. It looks like the i810 OSS drivers got
quite a rototilling in 2.6.7 and 2.6.8. It also kind of sounds like they
needed it though.

2.6.7:
<[EMAIL PROTECTED]>
[PATCH] I2C: ICH6/6300ESB i2c support
This patch adds DID support for ICH6 and 6300ESB to i2c-i801.c(SMBus).
In order to add this support I needed to patch pci_ids.h with the SMBus
DID's. To keep things orginized I renumbered the ICH6 and ESB entries
in pci_ids.h. I then patched the piix IDE and i810 audio drivers to
reflect the updated #define's. I also removed an error from irq.c;
there was a reference to a 6300ESB DID that does not exist.

[sound/oss i810] pci id cleanups
The driver defined its own PCI id constants. Kill the majority,
which were redundant, and move the rest to include/linux/pci_ids.h.
Also, move open-coded tests for "new ICH" audio chips to a single
helper function. These tests were being patched with each new
ICH motherboard from Intel, resulting in each new PCI id being added
to several places in the driver.
Note that, even though this should be a harmless patch, there
exists the remote possibility that I mis-matched some of the
PCI ids, as I only tested ICH5.

[sound/oss i810] fix wait queue race in drain_dac
This particular one fixes a textbook race condition in drain_dac
that causes it to timeout when it shouldn't.
<[EMAIL PROTECTED]>
[sound/oss i810] fix race
This patch fixes the value of swptr in case of an underrun/overrun.
Overruns/underruns probably won't occur at all when the driver is
fixed properly, but this doesn't hurt.
<[EMAIL PROTECTED]>
[sound/oss] remove bogus CIV_TO_LVI
This patch removes a pair of bogus LVI assignments. The explanation in
the comment is wrong because the value of PCIB tells the hardware that
the DMA buffer can be processed even if LVI == CIV.
Setting LVI to CIV + 1 causes overruns when with short writes
(something that vmware is very fond of).
<[EMAIL PROTECTED]>
[sound/oss i810] clean up with macros
This patch adds a number macros to clean up the code.
<[EMAIL PROTECTED]>
[sound/oss i810] fix partial DMA transfers
This patch fixes a longstanding bug in this driver where partial
fragments
are fed to the hardware. Worse yet, those fragments are then extended
while the hardware is doing DMA transfers causing all sorts of problems.
<[EMAIL PROTECTED]>
[sound/oss i810] fix playback SETTRIGGER
This patch fixes SETTRIGGER with playback so that the LVI is always
set and the DAC is always started.
<[EMAIL PROTECTED]>
[sound/oss i810] fix OSS fragments
This patch makes userfragsize do what it's meant to do: do not start
DAC/ADC until a full fragment is available.
<[EMAIL PROTECTED]>
[sound/oss i810] remove divides on playback
This patch removes a couple of divides on the playback path.
<[EMAIL PROTECTED]>
[sound/oss i810] fix drain_dac loop when signals_allowed==0
This patch fixes another bug in the drain_dac wait loop when it is
called with signals_allowed == 0.
<[EMAIL PROTECTED]>
[sound/oss i810] fix reads/writes % 4 != 0
This patch removes another bogus chunk of code that breaks when
the application does a partial write.
In particular, a read/write of x bytes where x % 4 != 0 will loop
forever.
<[EMAIL PROTECTED]>
[sound/oss i810] fix deadlock in drain_dac
This patch fixes a typo in a previous change that causes the driver
to deadlock under SMP.
2.6.8:
<[EMAIL PROTECTED]>
[sound/oss i810] add MMIO DSP support
Enclosed is a patch for the i810_audio OSS driver to support using
memory-mapped I/O for those chipsets that support it.
o Added a family of macros -- I810_IOREADx() and I810_IOWRITEx() --
that
key off the existing card->use_mmio flag to select between using
readx/writex
or inx/outx for I/O operations.
o Converted existing inx/outx invocations to use
I810_IOREADx/I810_IOWRITEx instead.
o Changed GET_CIV(), GET_LVI, and CIV_TO_LVI() not only to use
I810_IOREADx/I810_IOWRITEx but also to take "card" (i.e. struct
i810_card)
paramter.
o Removed check for "Pure MMIO interfaces" in i810_probe() -- replaced
w/
(relocated) check for no I/O resources available.
<[EMAIL PROTECTED]>
[sound/oss i810] misc small changes
Attached is a second patch to account for (most of) Herbert Xu's
comments.
I have left-out the part about changing state->card to a
local variable where it is used a lot. Unfortunately, that usage is
somewhat pervasive and I would prefer to make those changes in a
separate
patch -- after I have had a chance to do some testing.
If you'd prefer one patch to account for the original plus these
changes, let me know and I'll be happy to provide it.
