Can someone assist me in analyzing the data in this output from my
$ cat /proc/interrupts CPU0 CPU1 0: 22 0 IR-IO-APIC 2-edge timer 1: 2 0 IR-IO-APIC 1-edge i8042 8: 1 0 IR-IO-APIC 8-edge rtc0 9: 0 0 IR-IO-APIC 9-fasteoi acpi 12: 4 0 IR-IO-APIC 12-edge i8042 120: 0 0 DMAR-MSI 0-edge dmar0 122: 0 0 IR-PCI-MSI 327680-edge xhci_hcd 123: 25164 5760490 IR-PCI-MSI 1048576-edge enp2s0 124: 17 5424414 IR-PCI-MSI 524288-edge amdgpu
What I have compiled so far...
- Column 1: IRQ number
- Column 2&3: # of interrupts per CPU (variable # of columns depends on how many CPUs your system has)
- Column 4: Type of interrupt
- Column 5: ???
- Column 6: Name of device
I'm interested in finding out what data the 5th column contains, i.e.
524288-edge, and if someone can break down what the number represents. From researching online I only see the interrupt type column followed by the name of the device, this column data is always missing. Is it simply more information about the interrupt type?
