perf check [<options>]
perf check {feature <feature_list>} [<options>]

With no subcommands given, perf check command just prints the command usage on the standard output.

If the subcommand feature is used, then status of feature is printed on the standard output (unless -q is also passed), ie. whether it is compiled-in/built-in or not. Also, perf check feature returns with exit status 0 if the feature is built-in, otherwise returns with exit status 1.

feature

Print whether feature(s) is compiled-in or not, and also returns with an exit status of 0, if passed feature(s) are compiled-in, else 1.

It expects a feature list as an argument. There can be a single feature
name/macro, or multiple features can also be passed as a comma-separated
list, in which case the exit status will be 0 only if all of the passed
features are compiled-in.

The feature names/macros are case-insensitive.

Example Usage:
        perf check feature libtraceevent
        perf check feature HAVE_LIBTRACEEVENT
        perf check feature libtraceevent,bpf
