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

<div>&nbsp;I dont know if someone has any suggestions&nbsp;or a litle advice.</div>
<div>cheers</div>
