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 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_defconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:804: Warning: invalid register expression INFO: Uncompressed kernel (size 0x58c140) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x58c140) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x58c140) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x57ba90) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x58c140) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 03:28:06 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2796063 Bytes = 2730.53 KiB = 2.67 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 03:28:07 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2827235 Bytes = 2760.97 KiB = 2.70 MiB Load Address: 00600000 Entry Point: 006017dc Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 03:28:07 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2827576 Bytes = 2761.30 KiB = 2.70 MiB Load Address: 00600000 Entry Point: 00601a18 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc5 # Build took: 0:00:55.923179
