On a Linux system, you can find out how many interrupts have occurred on
each interrupt vector/CPU with “cat /proc/interrupts”. Is there any
equivalent on free or checked Windows?
$ cat /proc/interrupts
CPU0
0: 24614727 XT-PIC timer
1: 42801 XT-PIC keyboard
2: 0 XT-PIC cascade
4: 66658 XT-PIC serial
8: 1 XT-PIC rtc
9: 0 XT-PIC usb-uhci
10: 0 XT-PIC Intel ICH2
11: 14839239 XT-PIC usb-uhci, eth0
12: 522279 XT-PIC PS/2 Mouse
14: 809014 XT-PIC ide0
15: 24 XT-PIC ide1
NMI: 0
ERR: 0
kdex2x86 ‘idt’ command doesn’t provide any statistics.
PerfMon gives only total (sum of all interrupts) interrupt rate per CPU.
