+ 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.

+ default n
+ ---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.
