Hi,
Here is the 3rd version of the series for improving ftracetest testcase using gcov/lcov. In this version I just fixed some reported issues and dropped some tests which is not needed. I also dropped a testcase for blktrace from this version. It will be discussed separated thread.
Previous version is here;
https://lkml.org/lkml/2018/8/16/393
GCOV_PROFILE_FTRACE has already been merged through tracing tree.
Ftracetest framework improvements:
- Add --stop-fail for detecting failure soon.
- Add --console for interactively debugging a testcase by shell.
- Add testcase-number prefix to logfile for finding log easier.
- Improve general init function
- Add SPDX license identifiers
- Call general init function after all testcases.
- Remove init/cleanup code from all testcase (since general init function will fixed it up)
Testcase fixes:
- Fix to check $comm availability.
- Make checkbashisms clean
Testcase improvements:
- Use loopback address instead of localhost
- Improve kprobe on module testcase to load/unload module
- Improve kprobe testcase to check log data
- Improve kretprobe testcase to check log data
- Test kprobe-event argument with various bitsize
- Check set_event_pid result
Adding testcases:
- Add kprobe event with $comm argument testcase
- Add kprobe profile testcase
- Add kprobe-event with symbol argument testcase
- Add trace_printk sample module testcase
- Add ringbuffer size changing testcase
- Add function profiling statistics testcase
- Add max stack tracer testcase
- Add function filter on module testcase
- Add trace_pipe testcase
- Add stacktrace ftrace filter command testcase
- Add wakeup tracer testcase
- Add wakeup_rt tracer testcase
- Add ftrace cpumask testcase
TBD: Following testcase improvements are remaining.
- Checking of various supported types (like u8, u64 etc.) testcases
Tested on x86-64 qemu.
