Message-ID: <200207200155.20632.mah@tzi.de> (raw)

Hello,

I need the information about the time consumed when an interrupt occurs. 
Especially interesting is the time it takes from where the interrupt is 
generated (the device) until such time as the interrupt is reported to the 
cpu. 
Second,  I need to know the elapsed time from that point until the isr is 
entered.

On linuxdevices.com there is an article "Linux Scheduler Latency" by Clark 
Williams in which a comment by Ingo Molnar is quoted saying that the elapsed 
time takes 10 microseconds. Is that correct? Is there maybe any other source 
of information, someone could point me to?

BTW, i refer to the intel platform.

Thanks,
Mark
