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,  -vv,  -vvv,  --verbose

With a single -v, verbose level 1, only failing test output is displayed. With -vv and higher all test output is shown.

-S,  --sequential

Run all tests one after the other. By default "exclusive" tests are run sequentially, but other tests are run in parallel to speed execution.

-r,  --runs-per-test

Run each test the given number of times, by default once. This option can be useful to determine if a test is flaky.

-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.
