dear everybody, i had previous thread going on about the cpu load average. and had some discussion regarding it. i have a newer thing to discuss on so i started this thread. as i mentioned earlier i had put some code in the bridge.c that performed compression which took a long time and hence i got a high number of interface interrupts (irq22: xl interrupts). so i thought of rescheduling the compression tasks without blocking the bridge function. i found this function swi_add() which i could use to add software interrupt handlers that could be run at a later time without causing high interface interrupts. the man page discussed the swi_add() and swi_sched() functions. what i don't understand is, how do i register my handler function ?? if i use the swi_add() for that purpose what do i use for the void *arg argument. and how can i dispatch control to the software interrupt handler ?? the swi_sched() uses only the cookie and the flags arguments. there is no way i can pass arguments to my handler function .. i guess most of you are familiar with this and can help me out ...... thanks, kamal __________________________________________________ Do You Yahoo!?
