Hi, Sorry for the delay in responding.
Basically you need to create the stub interrupt handler (pmu_interrupt) in entry_64.S You also need to program the intr gate in i8259_64.c Finally you need to program the interrupt vector in the APIC entry for the PMU. This is accomplished by the perfmon code on demand (arch/x86/perfmon/perfmon.c). On Mon, Apr 21, 2008 at 8:58 AM, Amithash Prasad <[EMAIL PROTECTED]> wrote: > Anyway, I figured it out.

There's still time to save $100.
