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_85xx_tqm8541_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/tqm8541_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8541_defconfig_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_85xx_tqm8541_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8541_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x563664) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x552f68) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.9.0-rc2-g2e60265c1feb Created: Fri Sep 25 03:33:59 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2764003 Bytes = 2699.22 KiB = 2.64 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.9.0-rc2-g2e60265c1feb Created: Fri Sep 25 03:33:59 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2795000 Bytes = 2729.49 KiB = 2.67 MiB Load Address: 00600000 Entry Point: 00600314 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_tqm8541_defconfig_powerpc-gcc4.9 # Build took: 0:00:57.135408
