Hi List,
One of my main interests is in using linuxppc for DSP/Audio related tasks.
I am on the ALSA & audio-dev lists and there has been a lot of discussion
about achieving low-latency audio I/O.
Could anyone enlighten me as to the state of this topic wrt the linuxppc
kernels? It seems to be almost exclusively x86-related.
Specifically:
How does one profile the kernel?
Is there anyone (else) on the list who is trying to do the same kind of
thing?
Has anyone tried applying the low-latency patches (Ingo's) to *any* ppc
kernel?
does the ppc 2.4 kernel suffer from the (reported) VM issue that causes it
to exhibit *more* latency than 2.2.x kernels (this is the ststus of x86)?
I'm sure I'll have more questions soon...
TIA,
Iain.
