selftests/powerpc: Fix argument order to timer_sub()

2025-02-21T12:48:53+00:00

[ Upstream commit 2bf66e66d2e6feece6175ec09ec590a0a8563bdd ] Commit c814bf958926 ("powerpc/selftests: Use timersub() for gettimeofday()"), got the order of arguments to timersub() wrong, leading to a negative time delta being reported, eg: test: gettimeofday tags: git_version:v6.12-rc5-409-gdddf291c3030 time = -3.297781 success: gettimeofday The correct order is minuend, subtrahend, which in this case is end, start. Which gives: test: gettimeofday tags: git_version:v6.12-rc5-409-gdddf291c3030-dirty time = 3.300650 success: gettimeofday Fixes: c814bf958926 ("powerpc/selftests: Use timersub() for gettimeofday()") Signed-off-by: Michael Ellerman Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20241218114347.428108-1-mpe@ellerman.id.au Signed-off-by: Sasha Levin

selftests/powerpc: Fix error handling in FPU/VMX preemption tests

2024-01-25T23:27:19+00:00

[ Upstream commit 9dbd5927408c4a0707de73ae9dd9306b184e8fee ] The FPU & VMX preemption tests do not check for errors returned by the low-level asm routines, preempt_fpu() / preempt_vsx() respectively. That means any register corruption detected by the asm routines does not result in a test failure. Fix it by returning the return value of the asm routines from the pthread child routines.

selftests/powerpc: Fix emit_tests to work with run_kselftest.sh

2023-10-06T12:56:49+00:00

[ Upstream commit 58b33e78a31782ffe25d404d5eba9a45fe636e27 ] In order to use run_kselftest.sh the list of tests must be emitted to populate kselftest-list.txt. The powerpc Makefile is written to use EMIT_TESTS. But support for EMIT_TESTS was dropped in commit d4e59a536f50 ("selftests: Use runner.sh for emit targets"). Although prior to that commit a548de0fe8e1 ("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had already broken run_kselftest.sh for powerpc due to the executable check using the wrong path. It can be fixed by replacing the EMIT_TESTS definitions with actual emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh able to run powerpc tests: $ cd linux $ export ARCH=powerpc $ export CROSS_COMPILE=powerpc64le-linux-gnu- $ make headers $ make -j -C tools/testing/selftests install $ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt 182 Fixes: d4e59a536f50 ("selftests: Use runner.sh for emit targets") Signed-off-by: Michael Ellerman Link: https://msgid.link/20230921072623.828772-1-mpe@ellerman.id.au Signed-off-by: Sasha Levin

selftests/powerpc: Pass make context to children

2023-10-06T12:56:49+00:00

[ Upstream commit 4ecd0868c5138238dec8a1549bb6ff8e5b48208b ] Make supports passing the 'jobserver' (parallel make support) to child invocations of make when either 1. The target command uses $(MAKE) directly 2. The command starts with '+' This context is not passed through expansions that result in $(MAKE), so the macros used in several places fail to pass on the jobserver context. Warnings are also raised by the child mentioning this. Prepend macros lines that invoke $(MAKE) with '+' to allow passing the jobserver context to these children.

selftests/powerpc: Use CLEAN macro to fix make warning

2023-10-06T12:56:49+00:00

[ Upstream commit 69608683a65be5322ef44091eaeb9890472b2eea ] The CLEAN macro was added in 337f1e36 to prevent the Makefile:50: warning: overriding recipe for target 'clean' ../../lib.mk:124: warning: ignoring old recipe for target 'clean' style warnings.

selftests/powerpc/pmu: Fix sample field check in the mmcra_thresh_marked_sample_test

2023-05-11T14:03:31+00:00

[ Upstream commit 8a32341cf04ba05974931b4664683c2c9fb84e56 ] The testcase verifies the setting of different fields in Monitor Mode Control Register A (MMCRA). In the current code, EV_CODE_EXTRACT macro is used to extract the "sample" field, which then needs to be further processed to fetch rand_samp_elig and rand_samp_mode bits. But the current code is not passing valid sample field to EV_CODE_EXTRACT macro. Patch addresses this by fixing the input for EV_CODE_EXTRACT.

selftests/powerpc: Update bhrb filter sampling test for multiple branch filters

2022-09-28T09:22:13+00:00

For PERF_SAMPLE_BRANCH_STACK sample type, different branch_sample_type, ie branch filters are supported. The testcase "bhrb_filter_map_test" tests the valid and invalid filter maps in different powerpc platforms. Update this testcase to include scenario to cover multiple branch filters at sametime. Since powerpc doesn't support multiple filters at sametime, expect failure during perf_event_open.
