This patch schedules obsolete OSS drivers (with ALSA drivers that support the same hardware) for removal.
Scheduling the via82cxxx driver for removal was ACK'ed by Jeff Garzik.

Isn't this a bit premature? There are quite a few old mobo's with this chipset still in use, like my firewall box.

Gene, if you read the discussion regarding OSS, Adrian plans simply to remove drivers which have solid, known working replacements for all PCI ids in an equivalent ALSA driver.

Sorry, my bad.

The ad1889 ALSA driver was not present before 2.6.14 and therefore not on my original list.

Below is an updated patch that also schedules SOUND_AD1889 for removal.

I think these bug reports can be disregarded. The submitter never responded to requests to retest with the latest ALSA version. #1302 is almost certainly a bug in kphone anyway.

I would prefer if the ICH driver be kept. It works just fine on near all my systems and has a much smaller binary size than the ALSA variant. Moving to ALSA would bloat the kernels considerably.

This patch schedules obsolete OSS drivers (with ALSA drivers that support the same hardware) for removal.
Scheduling the via82cxxx driver for removal was ACK'ed by Jeff Garzik.
I would prefer if the ICH driver be kept. It works just fine on near all my systems and has a much smaller binary size than the ALSA variant. Moving to ALSA would bloat the kernels considerably.

The general decision for the OSS -> ALSA move was long ago.

If you have a real issue with the ALSA driver please submit a proper bug report to the ALSA bug tracking system and tell me the bug number.

If you compare the complete size of ALSA+driver vs OSS+driver then OSS wins easily on the bloat department.

If this is your problem then you should have vetoed the inclusion of ALSA into the kernel.

OK, what is your plan to make ALSA non-bloated?

E.g. it's clear that unused code or unused EXPORT_SYMBOL's in the kernel are bloat, so I am working on eliminating such bloat.

If you consider ALSA too bloated you should help on solving this issue instead of insisting on keeping OSS.

The biggest part is the PCM middle layer. It's bold. It's one of my TODO list to diet this one, especially for small systems.

The amount of ac97 codec support code may be easily reduced, too, by selecting codec chips to support. It's not a generic solution for distributions but good for private built kernels.

And thank you very much for that!

What's most notable to me is a substantial cross-arch reduction in .data space consumed. This non-FUSE-2.6.13 versus FUSE-2.6.14 UltraSPARC comparison shows this effect clearly:

On a similarly-configured Athlon the difference in .data is a little less pronounced, but still there.

UltraSPARC 2.6.13.4 versus 2.6.14 at boot:

Memory: 511576k available (2280k kernel code, 936k data, 128k init) [fffff80000000000,0000000037ebc000]
Memory: 511848k available (2288k kernel code, 672k data, 112k init) [fffff80000000000,0000000037ebc000]

(that's 264K, the same as the .data size difference above)

Athlon 2.6.13.4 versus 2.6.14 at book:

Memory: 774828k/786432k available (2794k kernel code, 11156k reserved, 1022k data, 148k init, 0k highmem)
Memory: 774996k/786432k available (2833k kernel code, 10988k reserved, 808k data, 152k init, 0k highmem)

(that's 214K different in .data although kernel code has grown a little here, probably thanks to FUSE).

Most OSes cannot claim to shrink across upgrades. Linux, at least the kernel, can. :)

The emu10k1 ALSA driver is considerably smaller than the OSS driver and has more features, like most ALSA drivers. If the ICH driver is really smaller I suspect it's missing some functionality.
