* selftests/ftrace: Add kprobe-event with symbol argument testMasami Hiramatsu2018-10-241-0/+1
| | | | | | | | | Add a testcase for kprobe-event with @symbol argument. Since @symbol needs to refer the kernel data symbol (linux_proc_banner), it requires CONFIG_KALLSYMS_ALL. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
* selftests/ftrace: Improve kprobe on module testcase to load/unload moduleMasami Hiramatsu2018-10-241-0/+4
| | | | | | | | | | Improve kprobe events on module testcase to check module load/unload with disabled/enabled events. This also change the target module to trace_printk.ko, so it depends on CONFIG_SAMPLE_TRACE_PRINTK=m.

| | | | | | | | | | | | | Here we add unit tests for the preemptoff and irqsoff tracer by using a kernel module introduced previously to trigger long preempt or irq disabled sections in the kernel.

* selftests: create test-specific kconfig fragmentsBamvor Jian Zhang2016-02-251-0/+1
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 <bamvor.zhangjian@linaro.org> Reviewed-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
