perf-test - Man Page

perf test [<options>] [{list <test-name-fragment>|[<test-name-fragments>|<test-numbers>]}]

This command does assorted sanity tests, initially through linked routines but also will look for a directory with more tests in the form of scripts.

To get a list of available tests use perf test list, specifying a test name fragment will show all tests that have it.

To run just specific tests, inform test name fragments or the numbers obtained from perf test list.

-s,  --skip

Tests to skip (comma separated numeric list).

-v,  --verbose

Be more verbose.

-S,  --sequential

Run tests one after the other, this is the default mode.

-p,  --parallel

Run tests in parallel, speeds up the whole process but is not safe with the current infrastructure, where some tests that compete for some resources, for instance, perf probe tests that add/remove probes or clean all probes, etc.

-F,  --dont-fork

Do not fork child for each test, run all tests within single process, this sets sequential mode.

--dso

Specify a DSO for the "Symbols" test.

-w,  --workload=

Run a built-in workload, to list them use --list-workloads, current ones include: noploop, thloop, leafloop, sqrtloop, brstack, datasym and landlock.

Used with the shell script regression tests.

Some accept an extra parameter:

seconds: leafloop, noploop, sqrtloop, thloop
nrloops: brstack

The datasym and landlock workloads don't accept any.

--list-workloads

List the available workloads to use with -w/--workload.
