Hello,
The aim of this patch series is to improve the resctrl selftest.
Without these fixes, some unnecessary processing will be executed
and test results will be confusing.
There is no behavior change in test themselves.
[patch 1] Make write_schemata() run to set up shemata with 100% allocation
on first run in MBM test.
[patch 2] The MBA test result message is always output as "ok",
make output message to be "not ok" if MBA check result is failed.
[patch 3] When a child process is created by fork(), the buffer of the
parent process is also copied. Flush the buffer before
executing fork().
[patch 4] Add a signal handler to cleanup properly before exiting the
parent process if there is an error occurs after creating
a child process with fork() in the CAT test, and unregister
signal handler when each test finished.
[patch 5] Before exiting each test CMT/CAT/MBM/MBA, clear test result
files function cat/cmt/mbm/mba_test_cleanup() are called
twice. Delete once.
This patch series is based on Linux v6.2-rc6.
Difference from v5:
[patch 4]
- If an error occurs in signal_handler_register() return -1,
and if an error occurs in signal_handler_unregister() does
not return any value.
- If signal_handler_register() fails, stop the running
parents&child process.
- Ignore the result of signal_handler_unregister()
so as not to overwrite earlier value of ret.
- Fix change log.
