Subject: [PATCH V3 00/35] Add group constraints and event code test as part of selftest
Date: Fri, 10 Jun 2022 19:10:38 +0530 [thread overview]
Message-ID: <20220610134113.62991-1-atrajeev@linux.vnet.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=301270
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 13 of the patchset add selftest for mmcr1 pmcxsel/unit/cache fields,
which was initially dropeed from sampling test patchset (patch number: 16)

Changelog:
v2 -> v3:
Changed name for generic compat PMU to ISAv3
in Patch2. This is based on recent patch sent by Joel
Stanley to change name for generic_compat_pmu to ISAv3.
http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=304131
v1 -> v2:
Patch 12: Fixed bhrb_filter_map testcase to address build failure in
distro like Ubuntu 16.04. This testcase uses perf branch sample
types from include/uapi/linux/perf_event.h and three of the sample
types are not defined in Ubuntu 16.04. Hence changed the logic to
loop over values from PERF_SAMPLE_BRANCH_USER_SHIFT to
PERF_SAMPLE_BRANCH_MAX_SHIFT as suggested by Michael Ellerman.
Patch 2: The sampling_tests/misc.c used pmu_name for generic compat pmu
as generic_compat_pmu. But latest version of patch to expose caps
in powerpc will use power_pmu->name. So change the pmu name in
misc code as GENERIC_COMPAT ( which is what pmu->name uses in driver
code).
