[linux-audio-dev] RE:HELP:porting linux audio driver to RTLinux(rtlinux core driver)

[nobin matthew]

Dear friends,

               The Real problem is, i need dma to fill
codec controller FIFO in every 600us(8 samples still
in codec FIFO and codec controller is half full, at
that time it will generate interrupts), this will
generate a sin wave which is used to controll another
device. If codec controller did not get data in this
period it sents last available sample again and again,
thus producing a straight line.  In Normal linux (2.4
kernel) interrupts and process scheduling may cause
problem. This is the reason for porting linux audio
driver to RTlinux and it is not possible to access
normal linux driver from RTLinux threads.
