[PATCH 6.5 250/285] selftests/ftrace: Fix dependencies for some of the synthetic event tests

by Greg Kroah-Hartman

6.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Naveen N Rao <naveen(a)kernel.org> [ Upstream commit 145036f88d693d7ef3aa8537a4b1aa22f8764647 ] Commit b81a3a100cca1b ("tracing/histogram: Add simple tests for stacktrace usage of synthetic events") changed the output text in tracefs README, but missed updating some of the dependencies specified in selftests. This causes some of the tests to exit as unsupported. Fix this by changing the grep pattern. Since we want these tests to work on older kernels, match only against the common last part of the pattern.

[PATCH RFC 0/3] selftests/nolibc: avoid spurious kernel relinks

by Thomas Weißschuh

Currently the nolibc testsuite embeds the test executable into a kernel image with CONFIG_INITRAMFS_SOURCE. This forces a full kernel relink everytime the test executable is updated. This relinking step dominates the test cycle. It is slower than building and running the test in qemu together. With a bit of Makefile-shuffling the relinking can be avoided.

[GIT PULL] Kselftest second fixes update for Linux 6.6-rc2

by Shuah Khan

Hi Linus, Please pull the following second Kselftest fixes update for Linux 6.6-rc2. This kselftest fixes update for Linux 6.6-rc2 consists of important fixes to user_events test and ftrace test. user_events test has been enabled for default run in Linux 6.6-rc1. The following fixes are for bugs found since then: - adds checks for dependencies and skips the test. user_events test requires root access, and tracefs and user_events enabled. It leaves tracefs mounted and a fix is in progress for that missing piece. - creates user_events test-specific Kconfig fragments. ftrace test fixes: - unmounts tracefs for recovering environment. Fix identified during the above mentioned user_events dependencies fix. - adds softlink to latest log directory improving usage. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit 0bb80ecc33a8fb5a682236443c1e740d5c917d1d: Linux 6.6-rc1 (2023-09-10 16:28:41 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux-kselftest-fixes-6.6-rc2 for you to fetch changes up to 7e021da80f48582171029714f8a487347f29dddb: selftests: tracing: Fix to unmount tracefs for recovering environment (2023-09-12 09:34:20 -0600) ---------------------------------------------------------------- linux-kselftest-fixes-6.6-rc2 This kselftest fixes update for Linux 6.6-rc2 consists of important fixes to user_events test and ftrace test. user_events test has been enabled for default run in Linux 6.6-rc1.

[PATCH 0/9] mm/damon: implement DAMOS apply intervals

by SeongJae Park

Changes from RFC (https://lore.kernel.org/damon/20230910034048.59191-1-sj@kernel.org/) - Add kselftest for damos_apply_interval_us sysfs file - Rebase on latest mm-unstable DAMON-based operation schemes are applied for every aggregation interval. That is mainly because schemes are using nr_accesses, which be complete to be used for every aggregation interval. This makes some DAMOS use cases be tricky. Quota setting under long aggregation interval is one such example. Suppose the aggregation interval is ten seconds, and there is a scheme having CPU quota 100ms per 1s. The scheme will actually uses 100ms per ten seconds, since it cannobe be applied before next aggregation interval. The feature is working as intended, but the results might not that intuitive for some users. This could be fixed by updating the quota to 1s per 10s. But, in the case, the CPU usage of DAMOS could look like spikes, and actually make a bad effect to other CPU-sensitive workloads. Also, with such huge aggregation interval, users may want schemes to be applied more frequently. DAMON provides nr_accesses_bp, which is updated for each sampling interval in a way that reasonable to be used. By using that instead of nr_accesses, DAMOS can have its own time interval and mitigate abovely mentioned issues. This patchset makes DAMOS schemes to use nr_accesses_bp instead of nr_accesses, and have their own timing intervals. Also update DAMOS tried regions sysfs files and DAMOS before_apply tracepoint to use the new data as their source. Note that the interval is zero by default, and it is interpreted to use the aggregation interval instead. This avoids making user-visible behavioral changes. Patches Seuqeunce ----------------- The first patch (patch 1/9) makes DAMOS uses nr_accesses_bp instead of nr_accesses, and following two patches (patches 2/9 and 3/9) updates DAMON sysfs interface for DAMOS tried regions and the DAMOS before_apply tracespoint to use nr_accesses_bp instead of nr_accesses, respectively. The following two patches (patches 4/9 and 5/9) implements the scheme-specific apply interval for DAMON kernel API users and update the design document for the new feature. Finally, the following four patches (patches 6/9, 7/9, 8/9 and 9/9) add support of the feature in DAMON sysfs interface, add a simple selftest test case, and document the new file on the usage and the ABI documents, repsectively.
