Title: buffer producer/consumer sync
hi ,
While debugging my alsa driver , some observations...
The flow goes like this
- cat test.raw /dev/pcm
- Middle layer fills up the buffer (size = period_size). Why does middle layer only fills up period_size ??
- ...(open / init etc)

Yes, on ARM platform you might have problem with MMU / cache coherency,
because appl_ptr and hw_ptr are mmaped to user space. I observed this
behaviour on SA11xx platform, too.

hi,
Just for your information we are using OSS PCM emulation. And let
me also first understand the problem :). Which I am not able to figure out
yet :(.

hi,
I was referring to a ARM implementation in the ALSA tree for our
ALSA driver development on OMAP 1610 (ARM 926)
sound\arm\sa11xx-uda1341.c. Just wanted to know if sa11xx-uda1341.c is also
affected by this problem.

And by that time, games will be even more demanding than before, and
still want to use those cycles for itself rather than software sound
processing, so just sitting idle waiting for the ultimate
infinite-megahertz cpu, that can do everything in no time, gains nobody
anything... at least our

I would really be amazed to have full Linux support for that device and
I've some programming capabilities as well.
But I'm not sure about, wether the NDA agrees in the basic alsa
principles. What are the developers of alsa are thinking about that
agreement?
Hi Hartmut.
