| |
Hello,
I'm trying to use code coverage measurements with mainline Linux kernel 2.6.35-rc6 on ARM platform (specifically on Samsung's S5PC110 board).
I've enabled following in my .config:
CONFIG_GCOV_KERNEL=y CONFIG_DEBUG_FS=y
After successful boot I see no gcov-related files other than /sys/kernel/debug/gcov/reset.
From my knowledge (and from my previous experience with out-of-tree gcov patchset) whole directory structure shall be created along with .gcda files and various symlinks.
I haven't used mainline gcov support yet, so maybe there are additional steps needed to get it going? Lecture of Documentation/gcov.txt didn't help much.
Hints?
Thanks in advance.
