Hardware Interrupts
PAPI_HW_INT
branches:u
x86 and x86_64
On x86 the hardware interrupt count also is added to the
retired instruction
and many of the other counts as well.
Pentium Pro, II, III
HW_INT_RX
(0xc8,0x00)
Core2
HW_INT_RCV
r5000c8
Atom
HW_INT_RCV
r5000c8 - note, that this doesn't work at all. r5001c8 counts, but counts a value two times as high, less two when hyperthreading is disabled (need to check enabled case).
Nehalem
HW_INT:RCV
r50011d -- support for this was dropped as of June 2010 Intel Vol3b? It seems to work...
SandyBridge
HW_INTERRUPTS:RECEIVED

AMD
