[alsa-devel] clarification on mmap

[Harsha, Priya]

Hi,

I have a question on mmap. If I give my .info to be _MMAP and _MMAP_VALID. Will ALSA framework internally take care of mmap-ing the kernel buffer that has been pre-allocated in the .probe call? Do I need to do anything special to mmap a kernel buffer into user space? Just accessing the runtime->dma_area would allow me to access user data right?

Thanks,
Harsha
