[alsa-devel] Timer interface

Hi,

I am extending my ALSA driver in order to support software mixing. Driver currently supports both MMAP and RW access modes. However, I am still not able to use dmix since it requires timer interface to be implemented. My hardware does not generate interrupts at the period boundary but issues timer interrupts at a fixed timer rate.

Could you please point me to the document or sample driver that can help me to fully understand timer interface concept (especially for High frequency timer interrupts)?

Thanks, Nenad
