2017-08-25selftests: lib.mk: change RUN_TESTS to print messages in TAP13 formatShuah Khan1-3/+9
Change common RUN_TESTS to print messages in user friendly TAP13 format. This change add TAP13 header at the start of RUN_TESTS target run, and prints the resulting pass/fail messages with test number information in the TAP 13 format for each test in the run tests list. This change covers test scripts as well as test programs. Test programs have an option to use ksft_ API, however test scripts won't be able to. With this change, test scripts can print TAP13 format output without any changes to individual scripts. Test programs can provide TAP13 format output as needed as some tests already do. Tests that haven't been converted will benefit from this change. Tests that are converted benefit from the test counts for all the tests in each test directory. Running firmware tests: make --silent -C tools/testing/selftests/firmware/ run_tests Before the change: modprobe: ERROR: could not insert 'test_firmware': Operation not permitted ./fw_filesystem.sh: /sys/devices/virtual/misc/test_firmware not present You must have the following enabled in your kernel: CONFIG_TEST_FIRMWARE=y selftests: fw_filesystem.sh [FAIL] modprobe: ERROR: could not insert 'test_firmware': Operation not permitted selftests: fw_fallback.sh [FAIL] After the change: TAP version 13 selftests: fw_filesystem.sh ======================================== modprobe: ERROR: could not insert 'test_firmware': Operation not permitted ./fw_filesystem.sh: /sys/devices/virtual/misc/test_firmware not present You must have the following enabled in your kernel: CONFIG_TEST_FIRMWARE=y not ok 1..1 selftests: fw_filesystem.sh [FAIL] selftests: fw_fallback.sh ======================================== modprobe: ERROR: could not insert 'test_firmware': Operation not permitted not ok 1..2 selftests: fw_fallback.sh [FAIL] Signed-off-by: Shuah Khan <[email protected]>
2017-08-25selftests: change lib.mk RUN_TESTS to take test list as an argumentShuah Khan2-15/+3
Change lib.mk RUN_TESTS to take test list as an argument. This will allow it to be called from individual test makefiles to run additional tests that aren't suitable for a default kselftest run. As an example, timers test includes destructive tests that aren't included in the common run_tests target. Change times/Makefile to use RUN_TESTS call with destructive test list as an argument instead of using its own RUN_TESTS target. Signed-off-by: Shuah Khan <[email protected]>

Output logs only to console if "-" is given to --logdir option. In this case, ftracetest doesn't record any log on the disk, and all logs immediately shown (including all command logs.)

Add 3-level verbosity for showing traced command log on console immediately. Since some test cases can cause kernel pacic if there is a probrem (like regression etc.), we can not know which command caused the problem without traced command log. This verbosity (-vvv) solves that because it shows the log on console immediately. User can get continuous command/error log. Note that this is a kind of kernel debug mode, if you don't see any kernel related issue, you don't need this verbosity.

Add --fail-unsupported option to fail the test result if ftracetest gets UNSUPPORTED result. UNSUPPORTED usually happens when the kernel is old (e.g. stable tree) or some kernel feature is disabled. However, if newer kernel has any bug or regression, it can make test results in UNSUPPORTED too. This option can detect such kernel regression.

2017-07-26selftests: ftrace: Do not failure if there is unsupported testsMasami Hiramatsu1-1/+1
Do not return failure exit code (1) for unsupported testcases, since it is expected for stable kernels. Previously, ftracetest is expected to run only on current release for avoiding regressions. However, nowadays we run it on stable kernels. This means some test cases must return unsupported result. In such case, we should NOT exit ftracetest with error status for unsupported results so that kselftest (upper tests wrapper) shows it passed correctly. Note that we continue to treat unresolved results as failure, if test writers would like to notice user that the test result should be reviewed, they can use exit_unresolved.

2017-07-24selftests: watchdog: get boot reason via WDIOC_GETBOOTSTATUSEugeniu Rosca1-1/+17
Some watchdog drivers implement WDIOF_CARDRESET feature. As example, see commit b6ef36d2c1e3 ("watchdog: qcom: Report reboot reason"). This option allows reporting to userspace the cause of the last boot (POR/watchdog reset), being helpful in e.g. automated test-cases. Add support for WDIOC_GETBOOTSTATUS in the test code, to be able to: - check if watchdog drivers properly implement WDIOF_CARDRESET. - check the last boot status, if WDIOF_CARDRESET is implemented. Make the `-b, --bootstatus` option one-shot. That means, skip the keepalive mechanism if `-b` is provided on the command line, as we are only interested in the boot status information. Tested on Rcar-H3 Salvator-X board: ********************** Cold boot finished salvator-x:/home/root# ./watchdog-test -h Usage: ./watchdog-test [options] -b, --bootstatus Get last boot status (Watchdog/POR) -d, --disable Turn off the watchdog timer -e, --enable Turn on the watchdog timer -h, --help Print the help message -p, --pingrate=P Set ping rate to P seconds (default 1) -t, --timeout=T Set timeout to T seconds Parameters are parsed left-to-right in real-time.

The only noticible changes, tightly related to the addition of getopt (and done for easier maintenance), are: - help message has been reworked and migrated to a dedicated function. - all short/long options and the help message are sorted alphabetically. - all case statements inside the getopt loop are sorted alphabetically.
