Subject: [PATCH 2/3] perf test: Introduce --list-workloads to list the available workloads
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Using it:
$ perf test -w noplop
No workload found: noplop
$
$ perf test -w
Error: switch `w' requires a value
Usage: perf test [<options>] [{list <test-name-fragment>|[<test-name-fragments>|<test-numbers>]}]
-w, --workload <work>
workload to run for testing, use '--list-workloads' to list the available ones.
$
$ perf test --list-workloads
noploop
thloop
leafloop
sqrtloop
brstack
datasym
landlock
$
Would be good at some point to have a description in 'struct test_workload'.
