Faster respond from poll

[Martin Ertsås]

Hi.

We're using the 3.3 kernel from the TI landing team. The problem we are
facing is with real time audio. We are, through gst-poll, calling poll
every 10th ms to get audio samples. Problem is that it doesn't respond
fast enough, and we only manage to get the samples every 15-30th ms.

We have turned off the 32khz and tickless kernel flags in the kernel,
which seems to have helped some. Problem is that it's not stable at all,
some times it's fast enough, and gives a nice long tone, other times it
have long delays like before.

Do you have any suggestions as to other kernel configs that might help
with this?

Any help would be greatly appreciated.
