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-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 abe22c0dd0c554ed01dd6bb9ec849797585e91aa # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xE56C77C5 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=n # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_BOOK3E_64=n # Added to kconfig CONFIG_PPC_BOOK3S_64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:6253:warning: override: reassigning to symbol CPU_BIG_ENDIAN .config:6256:warning: override: reassigning to symbol PPC_BOOK3E_64 .config:6258:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:6259:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:6260:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:6261:warning: override: reassigning to symbol LD_HEAD_STUB_CATCH .config:6263:warning: override: reassigning to symbol UBSAN # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/eeh.c:1571:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] 1571 | static int proc_eeh_show(struct seq_file *m, void *v) | ^~~~~~~~~~~~~ /kisskb/src/kernel/audit_fsnotify.c: In function 'audit_alloc_mark': /kisskb/src/kernel/audit_fsnotify.c:87:10: note: randstruct: casting between randomized structure pointer types (ssa): 'struct audit_fsnotify_mark' and 'struct dentry' 87 | return (void *)dentry; /* returning an error */ | ^~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: drivers/net/wireless/intel/iwlwifi/pcie/drv.o:(.toc+0x0): undefined reference to `iwl_so_trans_cfg' make[1]: *** [/kisskb/src/Makefile:1195: vmlinux] Error 1 make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 # Build took: 0:08:17.281480
