NAME
       perf-check - check if features are present in perf

SYNOPSIS
       perf check []
       perf check {feature } []

DESCRIPTION
       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.

SUBCOMMANDS
       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
