This may not be a desirable since # "perf" API is the primary interface to program PMU and # collect counter data in the system. But that said, we # cant remove these sysfs files since we dont whether # anyone/anything is using them. # # So the patch adds a new CONFIG option 'CONFIG_PMU_SYSFS' # (user selectable) to be used in sysfs file creation for # PMU SPRs. New option by default is disabled, but can be # enabled if user needs it. # # Tested this patch behaviour in powernv and pseries machines. # Patch is also tested for pmac32_defconfig. # # Signed-off-by: Kajol Jain # Tested-by: Nageswara R Sastry # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200214080606.26872-2-kjain@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 7f08c318df48fbcfc16a1cfbfad6818542510d57 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc885_ads_defconfig # Added to kconfig CONFIG_HUGETLBFS=y # yes \n | make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 04:08:09 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1961673 Bytes = 1915.70 KiB = 1.87 MiB Load Address: 00400000 Entry Point: 00400204 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc885_ads_defconfig+HUGETLB_powerpc-gcc5 # Build took: 0:00:56.976287
