HELP:porting linux PXA audio driver to RTLinux(RTLinux core driver)

[nobin matthew <nobin_matthew@yahoo.com>]

Dear Friends,

              I am trying to port Linux PXA audio
driver to RTLinux. I am using pxa-ac7.c and
pxa-audio.c
 and eliminated sound_core.c, and i will register two
device /dev/mixer and /dev/dsp to RTLinux kernel.

           The real need is, i wants to generate a sin
wave using audio codec. With in 600us DMA controller
should fill the codec FIFO, if that is not met
distortion will happen. I think normal linux
interrupts and Process scheduling may cause some
problems.

In porting it seems difficult to port kernel
scheduling , dynamic memory allocation(for DMA) and
synchronization.

Please help me
