The value of this event has changed # over time: # # - Power7 uses 0x400f0 # - Power8 and Power9 use both 0x400f0 and 0x3e054 # - Power10 uses only 0x3e054 # # Rather than relying on raw values, configure perf to count L1D read # misses in the most explicit way available. # # This fixes the selftests to work on systems without 0x400f0 as # PM_LD_MISS_L1, and should change no behaviour for systems that the tests # already worked on. # # The only potential downside is that referring to a specific perf event # requires PMU support implemented in the kernel for that platform. # # Signed-off-by: Russell Currey # Acked-by: Daniel Axtens # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20210223070227.2916871-1-ruscur@russell.cc # < /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 abe22c0dd0c554ed01dd6bb9ec849797585e91aa # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e49d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7d43c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:10 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3565282 Bytes = 3481.72 KiB = 3.40 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593766 Bytes = 3509.54 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593533 Bytes = 3509.31 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593984 Bytes = 3509.75 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593828 Bytes = 3509.60 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593704 Bytes = 3509.48 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.11.0-gabe22c0dd0c5 Created: Fri Feb 26 02:41:11 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3593812 Bytes = 3509.58 KiB = 3.43 MiB Load Address: 00800000 Entry Point: 00800294 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc5 # Build took: 0:00:56.917652
