OSS: cleanup or throw away

OSS: cleanup or throw away

[Jos Hulzink]

Hi,

While fixing some "deprecated" issues in the OSS drivers, I wondered whether 
this makes sense, as entire OSS is marked deprecated. Will OSS make it until 
2.7, or will it be dropped soon ? (In other words, should I take care of the 
OSS drivers or not bother about them)

Best regards,

Jos Hulzink

In my not so humble opinion, throwing OSS away will be a big mistake,
as long as there are people willing to maintain it. Keep it there and
let the users (or distributions) choose what to use. I've seen
multiple bug reports of cards that work with OSS and don't work with
ALSA (and vice versa), so keeping both seems the proper thing to
do. Personally, I maintain one OSS driver, and fix bugs in others
occasionally. 

Cheers, 
Muli

Looking at the amount of warnings in the OSS drivers (depricated 
check_region), the OSS drivers seem -with all respect for your hard work- not 
so well maintained anymore. I'm willing to fix them all, but not if entire 
OSS is ditched away Real Soon Now (tm).

Here's a log of a 'make allyesconfig', followed by 'make
sound/oss/', with gcc-3.3.2. This is really not too bad, almost
everything is trivial check_region -> request_region conversions. The
great majority of drivers compile just fine, and at least some of them
(those I have the hardware for) definitely work, too ;-)  

I intend to go through these warnings and fix them, now that I'm aware
of them. If you or anyone else want to collaborate on it,
great. Andrew Morton is taking OSS patches - I sent one on Saturday
night that's in 2.6.5-rc2-mm1 right now.

Cheers, 
Muli

Wouldn't it be better to get the ALSA drivers working in such cases?

It's really not a good idea to have two codebases for the same purpose.

It would; but until they do, ditching OSS is a regression.

It is if neither one is witholding effort from the other, and neither
one does a perfect job for all cases.

Clearly.

Ditching OSS at the beginning of 2.7 will give several years to identify 
and fix such regressions.

Seriously, ALSA has some issues at the moment which OSS doesn't have.
The main one is that OSS does not require mmap() access, whereas ALSA
native does at present - and there are architectures where the ALSA
method of mmap() both the ring buffer and the control data does not
work.

These issues aren't simple to resolve - as can be seen from the
recent lkml threads on the subject.  I've been seriously considering
submitting the existing OSS drivers I have here for ARM hardware
instead of trying to convert them to ALSA drivers first, and
considering whether I should be writing new OSS drivers in
preference to ALSA drivers.

That's not to say I don't want to see ALSA progress though - which is
why I'm working to try to get these issues resolved.

Or better: since both of OSS and ALSA are sound systems, let OSS maintainers
start hacking ALSA, so missing parts in ALSA which presents in OSS can be
implemented. Having one sound system would be better, especially in the
official kernel tree. It's another story, if you have multiple one outside
the "official" kernel source. imho.

Maybe we should start ditching OSS drivers of cards that are known to work
"reasonably well" in ALSA. If someone starts screaming "I need OSS for the
ALSA driver contains a bug", that bug might even be located and dealt with
much sooner. The ALSA OSS emulation is good enough for user land
applications to survive I think, so it's just a matter of driver bugs.

This way we end with a list of OSS drivers that are not ported yet or that
never will be ported.

OTOH, I don't know how the big bosses here think about ditching OSS
from a stable kernel tree... Can imagine they think it is not done.

Good idea, then maybe someone will fix the bug that makes ALSA unusable
for me. (Or maybe it's a feature? O_o)

I don't describe it here, I've sent a few mails about it, no response, so
I don't wait for any response this time either, so why bother.

It would be better to report bugs into our bug-tracking system or ask in
the alsa-user mailing list, if you have installation trouble.

Did you ever look into bugzilla.kernel.org?  There are about 45 bugs
open, might be nice to work on them (or tell people to report the bugs
elsewhere).  And yes, if I use vanilla 2.6, I report bugs here or in
bugzilla, not somewhere else.

Ok, I'll try to report about it later today, and no, it's not installation
problem. It's usage problem, using same two apps that work with OSS.

I discussed this with someone from the team already, don't remember who,
he gave me a few hints that helped me a bit, but not enough.

Thanks.

Please do, or give me a link, so I can collect the issues. Maybe the ALSA core 
team doesn't feel like looking at them now, but 2.6 will be here for a long 
time, no need to hurry.

OSS will stay in 2.6 (2.6 is a stable kernel series) but it will most
likely be removed in 2.7.

I wouldn't spend time to fix deprecated warnings in OSS code, such 
cleanups are wasted time for code that will most likely be removed in 
2.7.

Personally, as an user, I'd like to have the OSS drivers which don't have
a ALSA equivalent for my old hardware. There're several
sound cards with both ALSA and OSS drivers where ALSA works
much better 99% of the time. Those could be safely removed
(even in the 2.6 timeframe, I'd argue) but I'd like to keep the ones
without an alsa equivalent for my old hardware (specially now that we
have a -tiny tree ;) however I can understand that if they don't
have a maintainer they'll get removed...

 Also, I think is not good for the kernel to have code that does not
compile and/or compile with several warnings.

 So, if someone have time to work on it, is not bad.

Ok, it's clear OSS is here to stay for a while, and I will start working on 
it, if only for nice compile statistics.

These tiny patches might be a good way for me to get used to the beautiful 
world of kernel coding I think :)

Fair, but as I am not yet ready for the big work, this might be a nice 
exercise to find my way trough the kernel, to commit patches, etc. So I might 
spend a few weekends to it, albeit mostly to get nicer compile statistics :)

The real issue with removing OSS from a stable kernel is that a kernel 
update should not break existing system software (at least compliant 
software). As of early 2.6 it seemed that you had to update to the ALSA 
mixer and {something I don't remember} if you used the OSS emulation. I 
just used OSS and it worked. Based on only two systems, so it may not apply.

Stable and install new sound software don't seem to mix well. I suggest 
that the current course is a good one, keep both systems in the stable 
kernel.
