How can I allocate non-cacheable region for ring buffer?
I have an issue, where my DMA is not fetching right data from
Memory. I suspect that caching might be issue here.
I am using the below api to allocate memory:
retval = snd_pcm_lib_preallocate_pages_for_all(pcm,
Where, RING_MIN_BUFFER = RING_MAX_BUFFER = (8*1024)
