selftests: ftrace: Add check for function-fork before running pid filter test

2017-04-18T16:46:11+00:00

Have the func-filter-pid test check for the function-fork option before
testing it. It can still test the pid filtering, but will stop before
testing the function-fork option for children inheriting the pids.
This allows the test to be added before the function-fork feature, but after
a bug fix that triggers one of the bugs the test can cause.

selftests: ftrace: Add a testcase for function PID filter

2017-04-18T16:02:36+00:00

Like event pid filtering test, add function pid filtering test with the
new "function-fork" option.  It also tests it on an instance directory
so that it can verify the bug related pid filtering on instances.

selftests: enable O and KBUILD_OUTPUT

2017-01-05T20:42:22+00:00

Enable O and KBUILD_OUTPUT for kselftest. User could compile kselftest
to another directory by passing O or KBUILD_OUTPUT. And O is high
priority than KBUILD_OUTPUT.

selftests: add EXTRA_CLEAN for clean target

2017-01-05T20:42:17+00:00

Some testcases need the clean extra data after running. This patch
introduce the "EXTRA_CLEAN" variable to address this requirement.

After KBUILD_OUTPUT is enabled in later patch, it will be easy to
decide to if we need do the cleanup in the KBUILD_OUTPUT path(if the
testcase ran immediately after compiled).

selftests: remove useless TEST_DIRS

2017-01-05T20:41:56+00:00

The TEST_DIRS was introduced in Commit e8c1d7cdf137 ("selftests: copy
TEST_DIRS to INSTALL_PATH") for coping a whole directory in ftrace.

After rsync(with -a) is introduced by Commit 900d65ee11aa ("selftests:
change install command to rsync"). Rsync could handle the directory
without the definition of TEST_DIRS.

This patch simply replace TEST_DIRS with TEST_FILES in ftrace and remove
the TEST_DIRS in tools/testing/selftest/lib.mk

selftests: ftrace: Shift down default message verbosity

2016-12-13T16:28:10+00:00

Shift down default message verbosity, where it does not show
error results in stdout by default. Since that behavior
is the same as giving the --quiet option, this patch removes
--quiet and makes --verbose increasing verbosity.

In other words, this changes verbosity options as below.
ftracetest -q -> ftracetest
ftracetest    -> ftracetest -v
ftracetest -v -> ftracetest -v -v (or -vv)

selftests: ftrace: Add a testcase for types of kprobe event

2016-11-22T21:08:49+00:00

Add a testcase for types of kprobe event. This checks
kprobe event can accept and correctly expressed the
arguments typed as s32, u32, x32 and bitfield.

Here is the test result.
