SubjectRe: raw memory & PCI bus access

Hi all

Say I have a driver that realizes a "virtual irq" (/dev/irq).
User application waits for interrupts by calling select() for
that device. Obviously such a driver doesn't need much of code.
What a maximum latency between irq occurance and
userapp reaction I should expect?
