Linux Ftrace Testcases
|
||
|
|
|
||
|
|
This is a collection of testcases for ftrace tracing feature in the Linux
|
||
|
|
kernel. Since ftrace exports interfaces via the debugfs, we just need
|
||
|
|
shell scripts for testing. Feel free to add new test cases.
|
||
|
|
|
||
|
|
Running the ftrace testcases
|
||
|
|
============================
|
||
|
|
|
||
|
|
At first, you need to be the root user to run this script.
|
||
|
|
To run all testcases:
|
||
|
|
|
||
|
|
$ sudo ./ftracetest
|
||
|
|
|
||
|
|
To run specific testcases:
|
||
|
|
|
||
|
|
# ./ftracetest test.d/basic3.tc
|
||
|
|
|
||
|
|
Or you can also run testcases under given directory:
|
||
|
|
|
||
|
|
# ./ftracetest test.d/kprobe/
|
||
|
|
|
||
|
|
Contributing new testcases
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Copy test.d/template to your testcase (whose filename must have *.tc
|
||
|
|
extension) and rewrite the test description line.
|
||
|
|
|
||
|
|
* The working directory of the script is <debugfs>/tracing/.
|
||
|
|
|
||
|
|
* Take care with side effects as the tests are run with root privilege.
|
||
|
|
|
||
|
|
* The tests should not run for a long period of time (more than 1 min.)
|
||
|
|
These are to be unit tests.
|
||
|
|
|
||
|
|
* You can add a directory for your testcases under test.d/ if needed.
|
||
|
|
|
||
|
|
* The test cases should run on dash (busybox shell) for testing on
|
||
|
|
minimal cross-build environments.
