Subject: [PATCH 00/35] Add group constraints and event code test as part of selftest
Date: Fri,  6 May 2022 14:15:09 +0530	[thread overview]
Message-ID: <20220506084544.56527-1-kjain@linux.ibm.com> (raw)

Patch series extends the perf interface selftests
to cover scenarios for event code checking,
group constraints, and also thresholding/branch related
interface tests in sampling area.

In this series, patches 1 to 14 adds additional tests under
"powerpc/sampling_tests". These adds support for handling
sample type PERF_SAMPLE_BRANCH_STACK along with interrupt regs.
It adds utility functions and test for thresh_cmp and branch
filters programmed in control register. Some of the tests needs
to be skipped for "Generic Compat PMU" environment. Hence utility
functions are added in "include/utils.c" and "sampling_tests/misc.h"
to detect platform based on "auxv" entries.

Currently in other architectures (like x86), the pmu_name is
exposed via sysfs caps folder ie:
"sys/bus/event_source/devices/<pmu>/caps". But in powerpc,
"caps" is not supported. So, though the approach for detecting
compat mode currently uses auxv, patchset adds an 
utility function considering a possibility of
getting "caps" added for powerpc.

Link to the patch to add support for caps under sysfs in powerpc:
http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=297293

Patches 15 to 35 covers test related to group constraints and event codes.
These new set of changes are added under new folder:
"selftests/powerpc/pmu/event_code_tests"

Patch 15 covers changes required for new folder with Makefile changes.
The other patches add tests for perf interface to check the event
group constraints, valid/invalid event codes, blacklisted events etc.
Also add required utility functions under header file "misc.h"
in sampling_tests folder.

Patch 33 and 34 depend upon thresh_cmp group constraint fix patches
sent in upstream mailing list.

Link to the thresh_cmp fix patchset:
http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=298742

Patch 13 of the patchset add selftest for mmcr1 pmcxsel/unit/cache fields,
which was initially dropeed from sampling test patchset (patch number: 16)
