+	help
+	  perf (sometimes "Perf Events" or perf tools, originally
+	  "Performance Counters for Linux") - is a performance
+	  analyzing tool in Linux, available from kernel version
+	  2.6.31. User-space controlling utility, called 'perf' has
+	  git-like interface with subcommands. It is capable of
+	  statistical profiling of entire system (both kernel and user
+	  code), single CPU or severals threads.
+
+	  This package builds and install the userspace 'perf'
+	  command. It is up to the user to ensure that the kernel
+	  configuration has all suitable options enable to allow a
+	  proper operation of 'perf'.

+comment "perf only available if Linux kernel is enabled, and requires largefile support"
+	depends on !BR2_LINUX_KERNEL || !BR2_LARGEFILE
