Subject: HELP:porting linux PXA audio driver to RTLinux(RTLinux core driver)
Date: Fri, 8 Apr 2005 21:03:27 -0700 (PDT) [thread overview]
Message-ID: <20050409040327.93029.qmail@web53902.mail.yahoo.com> (raw)
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
Nobin Mathew
