i used the xenomai kernel side interrupt handler in this mode:

err = rt_intr_create( &rtFujInt, INTFUJITSUNAME, IRQFUJITSU, isrIntFujitsu ,
NULL, 0 );
if ( err != 0 )
   printk( "Impossible to create interrupt handler: %d\n", err );
   return 1;


I saw with the oscilloscope that there is a significant latency ( max ~110us
on ARM ep9315 ) before executing the first instruction of the handler
I listen that eventually i can use WIRED interrupt that is more fast.

How can i use it ?

Thanks for all
