Hi All,
I am stuck with a problem
I am writing a sound driver which works as soc device and use memory
mapping to communicate with alsa.
What i want to know that when i am using alsa's sine wave playback
application when it writes something to mapped memory then how it
signals to driver(kernel) that mapped memory has been written and it
should be flushed.
Thanks & Regards,
Dinesh Dua.
