Incase of # event codes using PMC5 and PMC6 ( 500fa and 600f4 respectively ), not # all constraints are applicable, say the threshold or sample bits. But # current code includes pmc5 and pmc6 in some group constraints (like # IC_DC Qualifier bits) which is actually not applicable and hence # results in those events not getting counted when scheduled along with # group of other events. Patch fixes this by excluding PMC5/6 from # constraints which are not relevant for it. # # Fixes: 7ffd948 ("powerpc/perf: factor out power8 pmu functions") # Signed-off-by: Athira Rajeev # Reviewed-by: Madhavan Srinivasan # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/1600672204-1610-1-git-send-email-atrajeev@linux.vnet.ibm.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 2e60265c1feb6848c77dbea22d38bbe262ec49db # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig # Added to kconfig CONFIG_CRASH_DUMP=y # Added to kconfig CONFIG_FA_DUMP=y # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4039:warning: override: reassigning to symbol CRASH_DUMP .config:4040:warning: override: reassigning to symbol FA_DUMP # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc4.9 # Build took: 0:03:52.028991
