[PATCH v5 0/5] Some improvements of resctrl selftest

by Shaopeng Tan

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-rc3. Difference from v4: [patch 4] - Reuse signal handler of other tests(MBM/MBA/CAT). - Unregister signal handler when tests finished. - Fix change log.

[PATCH AUTOSEL 6.1 12/35] kselftest: Fix error message for unconfigured LLVM builds

[PATCH 0/2] selftests/nolibc: small simplification of test development phase

by Willy Tarreau

Hello Paul, while developing and testing the recent changes for errno/environ/auxv, I found that I wasn't relying on the kernel that much and that I was mostly using qemu in userland only with my local kernel. I figured that it was more convenient for this purpose than rebuilding an initramfs and kernel for a quick test, and decided to make this approach easier to use for everyone by adding a "run-user" target to the Makefile to do exactly this. E.g: Native build: $ time make -C tools/testing/selftests/nolibc run-user ... make: Entering directory '/g/public/linux/master/tools/testing/selftests/nolibc' MKDIR sysroot/x86/include make[1]: Entering directory '/g/public/linux/master/tools/include/nolibc' make[2]: Entering directory '/g/public/linux/master' make[2]: Leaving directory '/g/public/linux/master' make[2]: Entering directory '/g/public/linux/master' INSTALL /g/public/linux/master/tools/testing/selftests/nolibc/sysroot/sysroot/include make[2]: Leaving directory '/g/public/linux/master' make[1]: Leaving directory '/g/public/linux/master/tools/include/nolibc' CC nolibc-test 18 chroot_root = -1 EPERM [FAIL] 43 link_dir = -1 EACCES != (-1 EPERM) [FAIL] See all results in /g/public/linux/master/tools/testing/selftests/nolibc/run.out make: Leaving directory '/g/public/linux/master/tools/testing/selftests/nolibc' real 0m0.966s user 0m0.731s sys 0m0.164s Cross build: $ time make -C tools/testing/selftests/nolibc run-user ARCH=s390 CROSS_COMPILE=/f/tc/nolibc/gcc-11.3.0-nolibc/s390-linux/bin/s390-linux- make: Entering directory '/g/public/linux/master/tools/testing/selftests/nolibc' MKDIR sysroot/s390/include make[1]: Entering directory '/g/public/linux/master/tools/include/nolibc' make[2]: Entering directory '/g/public/linux/master' make[2]: Leaving directory '/g/public/linux/master' make[2]: Entering directory '/g/public/linux/master' INSTALL /g/public/linux/master/tools/testing/selftests/nolibc/sysroot/sysroot/include make[2]: Leaving directory '/g/public/linux/master' make[1]: Leaving directory '/g/public/linux/master/tools/include/nolibc' CC nolibc-test 18 chroot_root = -1 EPERM [FAIL] 43 link_dir = -1 EACCES != (-1 EPERM) [FAIL] See all results in /g/public/linux/master/tools/testing/selftests/nolibc/run.out make: Leaving directory '/g/public/linux/master/tools/testing/selftests/nolibc' real 0m1.014s user 0m0.732s sys 0m0.183s In addition, the "x86_64" value for ARCH= is now supported as I got caught too many times with it not working in this subdir while it's used for the rest of the kernel ("x86" is used instead as coming from subarch.include). Generally you don't type it as x86_64 probably is the native build for most users, but when you start to test toolchains it's a different thing. There's no matter of urgency for these patches, they're just a bit of user-friendly stuff. As such, if you're fine with stacking them on top of what you already have for 6.3, that will be great, otherwise they can easily wait. Thank you! Willy [CCing Ammar who could benefit from this] --- Willy Tarreau (2): selftests/nolibc: support "x86_64" for arch name selftests/nolibc: add a "run-user" target to test the program in user land tools/testing/selftests/nolibc/Makefile | 10 ++++++++++ 1 file changed, 10 insertions(+) -- 2.17.5
