It is from “bhrb_filter_map_test" which uses some of the branch sample types that is not supported in Ubuntu 16.04 So we hit this: bhrb_filter_map_test.c:38:2: error: 'PERF_SAMPLE_BRANCH_NO_FLAGS' undeclared here (not in a function) 1329 PERF_SAMPLE_BRANCH_NO_FLAGS, 1330 ^ 1331 bhrb_filter_map_test.c:39:2: error: 'PERF_SAMPLE_BRANCH_NO_CYCLES' undeclared here (not in a function) 1332 PERF_SAMPLE_BRANCH_NO_CYCLES, 1333 ^ 1334 bhrb_filter_map_test.c:40:2: error: 'PERF_SAMPLE_BRANCH_TYPE_SAVE' undeclared here (not in a function) 1335 PERF_SAMPLE_BRANCH_TYPE_SAVE, 1336 ^ We will send a V2 with fix and run against ci.

2.31.1
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
