 hi all of you ,
I am wndering if someone has already done test for interrupt latency on
linx 2.6.23 mpc5200b.
I am working on writing a driver which is get SPi involved on design, and I
know that the  spi interrupt will occurs at every 2 us ( speed 4 MHz
interupt occurs when It recieves on bytes) so  I am worring about interrupt
latency.
 I dont know if someone has any suggestions or a litle advice.
cheers
