Followed the iknstreuction I have patched the gcov patch to the kernel
and recompiled it correctly. The new kernel with gcov patch can boot up
correctly, also the command "modprobe gcov-proc" executed. It seems the
modules can correctly load.
following are errors i encounted, when access kernel data:=20
lcov --capture --output-file kernel.info=20
Copying kernel data to temporary
Capturing coverage data from /tmp/tmpdir607
Found gcov version: 3.4.5
Scanning /tmp/tmpdir607 for .gcda files ...
ERROR: no .gcda files found in /tmp/tmpdir607!
Removing temporary directory /tmp/tmpdir607
who to cope with it?
