2016-02-25selftests: create test-specific kconfig fragmentsBamvor Jian Zhang1-0/+2
Create the config file in each directory of testcase which need more kernel configuration than the default defconfig. User could use these configs with merge_config.sh script: Enable config for specific testcase: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/xxx/config Enable configs for all testcases: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/*/config Signed-off-by: Bamvor Jian Zhang <[email protected]> Reviewed-by: Shuah Khan <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
2015-04-01selftests: change cpu on-off-test.sh name to be uniqueShuah Khan2-2/+2
cpu and memory hotplug scripts use the same name. Change cpu on-off-test.sh to cpu-on-off-test.sh. Signed-off-by: Shuah Khan <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]>
2015-03-13selftests: Introduce minimal shared logic for running testsMichael Ellerman2-2/+3
This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

2014-07-11tools: selftests - create a separate hotplug target for full range testShuah Khan2-2/+53
On some systems, hot-plug tests could hang forever waiting for cpu and memory to be ready to be offlined. A special hot-plug target is created to run full range of hot-plug tests. In default mode, hot-plug tests run in safe mode with a limited scope. In limited mode, cpu-hotplug test is run on a single cpu as opposed to all hotplug capable cpus, and memory hotplug test is run on 2% of hotplug capable memory instead of 10%. In addition to the above change, cpu-hotplug is chnged to change processor affinity to cpu 0 so it doesn't impact itself while the test runs.

2014-07-11tools: cpu-hotplug fix unexpected operator errorShuah Khan1-1/+1
on-off-test is a bash script and invoked from /bin/sh This results in the following error: ./on-off-test.sh: 9: [: !=: unexpected operator Changed Makefile to use bash instead. Signed-off-by: Shuah Khan <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2012-07-30fault-injection: add selftests for cpu and memory hotplugAkinobu Mita2-0/+227
This adds two selftests * tools/testing/selftests/cpu-hotplug/on-off-test.sh is testing script for CPU hotplug 1. Online all hot-pluggable CPUs 2. Offline all hot-pluggable CPUs 3. Online all hot-pluggable CPUs again 4. Exit if cpu-notifier-error-inject.ko is not available 5. Offline all hot-pluggable CPUs in preparation for testing 6. Test CPU hot-add error handling by injecting notifier errors 7. Online all hot-pluggable CPUs in preparation for testing 8. Test CPU hot-remove error handling by injecting notifier errors * tools/testing/selftests/memory-hotplug/on-off-test.sh is doing the similar thing for memory hotplug. 1. Online all hot-pluggable memory 2. Offline 10% of hot-pluggable memory 3. Online all hot-pluggable memory again 4. Exit if memory-notifier-error-inject.ko is not available 5. Offline 10% of hot-pluggable memory in preparation for testing 6. Test memory hot-add error handling by injecting notifier errors 7. Online all hot-pluggable memory in preparation for testing 8.
