Hi All,

Sorry for the wide distribution:

According to LTP page info,
http://ltp.sourceforge.net/coverage/gcov.php
http://ltp.sourceforge.net/coverage/lcov.php

My question is
How to get kernel coverage when I run LTP test?

Since we do not have direct GCOV support on ARM I have enabled ( just
for experiment)

$ git diff  kernel/gcov/Kconfig
diff --git a/kernel/gcov/Kconfig b/kernel/gcov/Kconfig
index d4da55d..fceac85 100644

        This options activates profiling for the entire kernel.

I have enabled below kernel config and built the kernel.
CONFIG_GCOV_KERNEL=y
CONFIG_GCOV_PROFILE_ALL=y
CONFIG_GCOV_FORMAT_AUTODETECT=y

of course I have disabled gcov on below folders and files, because
since it is an experiment i would like to be on safe side
- arch/arm/mm/
- arch/arm/kernel/
- arch/arm/boot/
- arch/arm/boot/compressed/
- arch/arm/boot/bootp/
- arch/arm/boot/dts

Arndale booted with this configuration successfully.
Took more than 65 seconds to finish boot.

gcov related files are found under /sys/ similer to X86 machine.
And  gcov supporting files filename.gcda are having links to kernel source

The above experiment gives coverage of a single file base.c when i run
gcov manually.
Is there any way to get Linux kernel coverage of all files after
running LTP test cases ?

Thanks in advance.

1. Reset coverage data: lcov -z
2. Run LTP (or any other test case)
3. Capture coverage data: lcov -c -o coverage.info
4. Generate HTML output: genhtml coverage.info -o out
5. View HTML output: <browser> out/index.html

More information on lcov can be found on the page behind the second URL
your quoted in your mail.

1. Reset coverage data: lcov -z
2. Run LTP (or any other test case)
3. Capture coverage data: lcov -c -o coverage.info
4. Generate HTML output: genhtml coverage.info -o out
5. View HTML output: <browser> out/index.html

It is working !!!
LTP executed on linux-linaro build on vexpress-tc2 target.
Please find results obtained
http://people.linaro.org/~naresh.kamboju/linux-linaro-coverage-by-ltp/

The plan is to run all linaro test suite and to get coverage date.

Peter Oberparleiter,
Thank you very much for your help.

It is working !!!
LTP executed on linux-linaro build on vexpress-tc2 target.
Please find results obtained
http://people.linaro.org/~naresh.kamboju/linux-linaro-coverage-by-ltp/

The plan is to run all linaro test suite and to get coverage date.

Peter Oberparleiter,
Thank you very much for your help.

Best regards
Naresh Kamboju

I have tested LTP on vexpress-tc2. I did not try all test suites.
We ( In Linaro) Linaro Test Suites is a package that contains test
suites that can be run in LAVA.
