NAME

lsirq - utility to display kernel interrupt information

SYNOPSIS

OPTIONS

Specify which output columns to print. Use --help to get a list of all supported columns. The default list of columns may be extended if list is specified in the format +list .

-s , --sort column

Specify sort criteria by column name. See --help output to get column names.

-J , --json

Use JSON output format.

-P , --pairs

Produce output in the form of key="value" pairs. All potentially unsafe characters are hex-escaped (\x<code>).

Show softirqs information.

-t , --threshold min

Only show IRQs with counters above the specified threshold. Human readable values are supported (e.g. 1.2K).
