arm32: kselftest: zram: Unable to handle kernel NULL pointer dereference at virtual address 00000144

by Naresh Kamboju

While running kselftest zram test case on x15 device and qemu-arm on stable-rc 6.0.7-rc1 the following kernel crash noticed the image was built with gcc-10. This is not regression because it has been happening on mainline and next.

[PATCH V5 0/5] Add tbench/gitsource new test cases for amd-pstate-ut

by Meng Li

Hi all: First, rename amd-pstate-ut.sh to basic.sh as a basic test, mainly for AMD P-State kernel drivers. The purpose of this modification is to facilitate the subsequent addition of gitsource, tbench and other tests. Second, split basic.sh into run.sh and basic.sh. The modification makes basic.sh more pure, just for test basic kernel functions. The file of run.sh mainly contains functions such as test entry, parameter check, prerequisite and log clearing etc. Third, add tbench.sh trigger the tbench testing and monitor the cpu. Fourth, add gitsource.sh trigger the gitsource testing and monitor the cpu information. Finally, modify rst document to introduce test steps and results etc. See patch series in below git repo: V1:https://lore.kernel.org/lkml/20220706073622.672135-1-li.meng@amd.com/ V2:https://lore.kernel.org/lkml/20220804054414.1510764-1-li.meng@amd.com/ V3:https://lore.kernel.org/lkml/20220914061105.1982477-1-li.meng@amd.com/ V4:https://lore.kernel.org/lkml/20221024013356.1639489-1-li.meng@amd.com/ Changes from V1->V2: - selftests: amd-pstate: basic - - delete main.sh and merge funtions into run.sh - selftests: amd-pstate: tbench - - modify ppw to performance per watt for tbench. - - add comments for performance per watt for tbench. - - add comparative test on acpi-cpufreq for tbench. - - calculate drop between amd-pstate and acpi-cpufreq etc. - - plot images about perfrmance,energy and ppw for tbench. - selftests: amd-pstate: gitsource - - modify ppw to performance per watt for gitsource. - - add comments for performance per watt for gitsource. - - add comparative test on acpi-cpufreq for gitsource. - - calculate drop between amd-pstate and acpi-cpufreq etc. - - plot images about perfrmance,energy and ppw for gitsource. - Documentation: amd-pstate: - - modify rst doc, introduce comparative test etc. Changes from V2->V3: - selftests: amd-pstate: - - reduce print logs for governor. - - add a check to see if tbench and the perf tools are already installed. - - install tbench package from apt or yum. - - correct spelling errors from comprison to comparison.

[PATCH 0/8] efficiently expose damos action tried regions information

by SeongJae Park

Changes from RFC (https://lore.kernel.org/damon/20221019001317.104270-1-sj@kernel.org/): - Split out cleanup/refactoring parts[1] [1] https://lore.kernel.org/damon/20221026225943.100429-1-sj@kernel.org/ ----------------------------------------------------------------------- DAMON users can retrieve the monitoring results via 'after_aggregation' callbacks if the user is using the kernel API, or 'damon_aggregated' tracepoint if the user is in the user space. Those are useful if full monitoring results are necessary. However, if the user has interest in only a snapshot of the results for some regions having specific access pattern, the interfaces could be inefficient. For example, some users only want to know which memory regions are not accessed for more than a specific time at the moment. Also, some DAMOS users would want to know exactly to what memory regions the schemes' actions tried to be applied, for a debugging or a tuning. As DAMOS has its internal mechanism for quota and regions prioritization, the users would need to simulate DAMOS' mechanism against the monitoring results. That's unnecessarily complex. This patchset implements DAMON kernel API callbacks and sysfs directory for efficient exposure of the information for the use cases. The new callback will be called for each region when a DAMOS action is gonna tried to be applied to it. The sysfs directory will be called 'tried_regions' and placed under each scheme sysfs directory. Users can write a special keyworkd, 'update_schemes_regions', to the 'state' file of a kdamond sysfs directory. Then, DAMON sysfs interface will fill the directory with the information of regions that corresponding scheme action was tried to be applied for next one aggregation interval. Patches Sequence ---------------- The first one (patch 1) implements the callback for the kernel space users. Following two patches (patches 2 and 3) implements sysfs directories for the information and its sub directories. Two patches (patches 4 and 5) for implementing the special keywords for filling the data to and cleaning up the directories follow. Patch 6 adds a selftest for the new sysfs directory. Finally, two patches (patches 7 and 8) document the new feature in the administrator guide and the ABI document. Assembled Tree -------------- This patchset is based on the latest mm-unstable tree[1]. Assembled tree is also available at the damon/next tree[2].

[PATCH RFC] drm/i915: allow running mock selftests via Kunit

by Mauro Carvalho Chehab

The mock selftests don't require any hardware to run. They can easily run via kunit with qemu or bare metal. Add support for it. With this change, mock selftest can now run in qemu with: $ ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kunitconfig=drivers/gpu/drm/i915/selftests [16:50:24] Configuring KUnit Kernel ...
