A future patch will reenable it at a later # stage once a workaround has been developed. # # Fixes: 012ae244845f ("powerpc/perf: Trace imc PMU functions") # Cc: stable@vger.kernel.org # v5.2+ # Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> # Tested-by: Hariharan T.S. <hari@linux.ibm.com> # [mpe: Add pr_info_once() so dmesg shows the PMU has been disabled] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191118034452.9939-1-maddy@linux.vnet.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 249fad734a25889a4f23ed014d43634af6798063 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/kmeter1_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x589514) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.4.0-g249fad734a25 Created: Fri Dec 6 03:14:26 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2826496 Bytes = 2760.25 KiB = 2.70 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc-gcc5 # Build took: 0:00:48.409371
