SubjectGCOV doesn't seem to work on ARM with kernel 2.6.35-rc6
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.
