Sysbox: lsisr

Usage: lsisr [OPTION]...

List Interrupt Service Routines (ISRs). Only administrators (those who run in super tasks) can perform this operation.

This tool is useful to determine which IRQ numbers are used, or which numbers are unused.

Options:

-i
Organize the output by ISRs. In other words, group by IRQ numbers. This is the default mode.
-n
Resolve task name if possible.
-N
Do not resolve task names. Enabled by default.
-t
Organize the output by tasks. Useful to determine which tasks created ISRs and which IRQ numbers are used by those ISRs.

Examples (Important! Only super tasks can perform these):
