+config GCOV_KERNEL

+	depends on DEBUG_FS
+	select CONSTRUCTORS if !UML
+	default n
+	---help---
+	This option enables gcov-based code profiling (e.g. for code coverage
+	measurements).
+
+	If unsure, say N.
+
+	Additionally specify CONFIG_GCOV_PROFILE_ALL=y to get profiling data
+	for the entire kernel. To enable profiling for specific files or
+	directories, add a line similar to the following to the respective
+	Makefile:
+
+	For a single file (e.g. main.o):
+	        GCOV_PROFILE_main.o := y
+
+	For all files in one directory:
+	        GCOV_PROFILE := y
+
+	To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
+	is specified, use:
+
+	        GCOV_PROFILE_main.o := n
+	and:
+	        GCOV_PROFILE := n
+
+	Note that the debugfs filesystem has to be mounted to access
+	profiling data.

+	---help---
+	This options activates profiling for the entire kernel.
+
+	If unsure, say N.
+
+	Note that a kernel compiled with profiling flags will be significantly
+	larger and run slower. Also be sure to exclude files from profiling
+	which are not linked to the kernel image to prevent linker errors.

+	---help---
+	The gcov format is usually determined by the GCC version, but there are
+	exceptions where format changes are integrated in lower-version GCCs.
+	In such a case use this option to adjust the format used in the kernel
+	accordingly.
+
+	If unsure, choose "Autodetect".
