[PATCH 0/5] selftests/resctrl: Some improvements of resctrl selftest
From: Shaopeng Tan
Date: Tue Sep 13 2022 - 21:56:10 EST
Hello,
The aim of this patch series is to improve the resctrl selftest.
The first three patches clear redundant code.
The last two patches are bug fixes. Without the two fixes,
some unnecessary processing will be executed and test results
will be confusing. There is no behavior change in test themselves.
[patch 1] Because the default schemata is 100% , in MBM test
it is not necessary to reset schemata by write_schemata().
[patch 2] Delete CMT-related processing in write_schemata() which is
not called by CMT.
[patch 3] Before exiting each test CMT/CAT/MBM/MBA, clear test result
files function cat/cmt/mbm/mba_test_cleanup() are called twice.
Delete once.
[patch 4] If there is an exception occurs after creating a child
process with fork() in the CAT test, kill the child process
before terminating the parent process.
[patch 5] When a child process is created by fork(), the buffer of the
parent process is also copied. Flush the buffer before executing fork().
This patch series is based on Linux v6.0-rc5
