[PATCH 0/2] selftests/lib.mk: LLVM=1, CC=clang, and warnings

by John Hubbard

The kselftests may be built in a couple different ways: make LLVM=1 make CC=clang In order to handle both cases, set LLVM=1 if CC=clang. That way,the rest of lib.mk, and any Makefiles that include lib.mk, can base decisions solely on whether or not LLVM is set. Then, build upon that to disable a pair of clang warnings that are already silenced on gcc. Doing it this way is much better than the piecemeal approach that I started with in [1] and [2]. Thanks to Nathan Chancellor for the patch reviews that led to this approach.

[PATCH v4 00/16] selftests/resctrl: resctrl_val() related cleanups & improvements

by Ilpo Järvinen

Hi all, This series does a number of cleanups into resctrl_val() and generalizes it by removing test name specific handling from the function. One of the changes improves MBA/MBM measurement by narrowing down the period the resctrl FS derived memory bandwidth numbers are measured over. My feel is it didn't cause noticeable difference into the numbers because they're generally good anyway except for the small number of outliers. To see the impact on outliers, I'd need to setup a test to run large number of replications and do a statistical analysis, which I've not spent my time on. Even without the statistical analysis, the new way to measure seems obviously better and makes sense even if I cannot see a major improvement with the setup I'm using. v4: - Merged close fix into IMC READ+WRITE rework patch - Add loop to reset imc_counters_config fds to -1 to be able know which need closing - Introduce perf_close_imc_mem_bw() to close fds - Open resctrl mem bw file (twice) beforehand to avoid opening it during the test - Remove MBM .mongrp setup - Remove mongrp from CMT test v3: - Rename init functions to <testname>_init() - Replace for loops with READ+WRITE statements for clarity - Don't drop Return: entry from perf_open_imc_mem_bw() func comment - New patch: Fix closing of IMC fds in case of error - New patch: Make "bandwidth" consistent in comments & prints - New patch: Simplify mem bandwidth file code - Remove wrong comment - Changed grp_name check to return -1 on fail (internal sanity check) v2: - Resolved conflicts with kselftest/next - Spaces -> tabs correction Ilpo Järvinen (16): selftests/resctrl: Fix closing IMC fds on error and open-code R+W instead of loops selftests/resctrl: Calculate resctrl FS derived mem bw over sleep(1) only selftests/resctrl: Make "bandwidth" consistent in comments & prints selftests/resctrl: Consolidate get_domain_id() into resctrl_val() selftests/resctrl: Use correct type for pids selftests/resctrl: Cleanup bm_pid and ppid usage & limit scope selftests/resctrl: Rename measure_vals() to measure_mem_bw_vals() & document selftests/resctrl: Simplify mem bandwidth file code for MBA & MBM tests selftests/resctrl: Add ->measure() callback to resctrl_val_param selftests/resctrl: Add ->init() callback into resctrl_val_param selftests/resctrl: Simplify bandwidth report type handling selftests/resctrl: Make some strings passed to resctrlfs functions const selftests/resctrl: Convert ctrlgrp & mongrp to pointers selftests/resctrl: Remove mongrp from MBA test selftests/resctrl: Remove mongrp from CMT test selftests/resctrl: Remove test name comparing from write_bm_pid_to_resctrl() tools/testing/selftests/resctrl/cache.c | 6 +- tools/testing/selftests/resctrl/cat_test.c | 5 +- tools/testing/selftests/resctrl/cmt_test.c | 22 +- tools/testing/selftests/resctrl/mba_test.c | 26 +- tools/testing/selftests/resctrl/mbm_test.c | 26 +- tools/testing/selftests/resctrl/resctrl.h | 49 ++- tools/testing/selftests/resctrl/resctrl_val.c | 362 ++++++++---------- tools/testing/selftests/resctrl/resctrlfs.c | 64 ++-- 8 files changed, 287 insertions(+), 273 deletions(-) -- 2.39.2

[PATCH v2 0/3] selftests/futex: clang-inspired fixes

by John Hubbard

Hi, Here's a few fixes that are part of my effort to get all selftests building cleanly under clang. Plus one that I noticed by inspection. Changes since the first version: 1) Rebased onto Linux 6.10-rc1 2) Added Reviewed-by's. ...and it turns out that all three patches are still required, on -rc1, in order to get a clean clang build. Enjoy! thanks, John Hubbard John Hubbard (3): selftests/futex: don't redefine .PHONY targets (all, clean) selftests/futex: don't pass a const char* to asprintf(3) selftests/futex: pass _GNU_SOURCE without a value to the compiler tools/testing/selftests/futex/Makefile | 2 -- tools/testing/selftests/futex/functional/Makefile | 2 +- tools/testing/selftests/futex/functional/futex_requeue_pi.c | 2 +- 3 files changed, 2 insertions(+), 4 deletions(-) base-commit: e0cce98fe279b64f4a7d81b7f5c3a23d80b92fbc -- 2.45.1

[PATCH 0/4] selftests/resctrl: Enable MBM and MBA tests on AMD

by Babu Moger

The MBM (Memory Bandwidth Monitoring) and MBA (Memory Bandwidth Allocation) features are not enabled for AMD systems. The reason was lack of perf counters to compare the resctrl test results. Starting with the commit 25e56847821f ("perf/x86/amd/uncore: Add memory controller support"), AMD now supports the UMC (Unified Memory Controller) perf events. These events can be used to compare the test results. This series adds the support to detect the UMC events and enable MBM/MBA tests for AMD systems. Babu Moger (4): selftests/resctrl: Rename variable imcs and num_of_imcs() to generic names selftests/resctrl: Pass sysfs controller name of the vendor selftests/resctrl: Add support for MBM and MBA tests on AMD selftests/resctrl: Skip the tests if iMC/UMC counters are unavailable tools/testing/selftests/resctrl/resctrl.h | 1 + .../testing/selftests/resctrl/resctrl_tests.c | 16 ++- tools/testing/selftests/resctrl/resctrl_val.c | 105 ++++++++++++++---- 3 files changed, 96 insertions(+), 26 deletions(-) -- 2.34.1
