Hi, i am a student of telecommunication engineering and i need some help for
my thesis...
i am using the ep9302 for adquire stream data (MPEG2 Transport Stream) with
a DMA approach.
This issue can be resolved by using the M2M channel and the handshaking
signals for syncronize the peripheral and the dma controller.
i have already done the driver (even if it still doesn't work perfectly...)
for the 2.6.13-gao66 kernel to control the dma; the next step is to
demultiplex the signal that there is in the dma buffer (the driver that i
have already done reads the packets from satellite and put them in the dma
buffer). Did anyone already solve this kind of problem (a demux in kernel
mode)? If someone did that i'd really appreciate the source code and, if
interested (at your own risk! ;-)....), i could give my driver...
Thanks for any help!
