This breaks for offline # CPUs because they don't get the IPI to flush their TLB. This can lead # to stale translations. # # Fix this by clearing the CPU from mm_cpumasks, then flushing all TLBs # before going offline. # # These offlined CPU bits stuck in the cpumask also prevents the cpumask # from being trimmed back to local mode, which means continual broadcast # IPIs or TLBIEs are needed for TLB flushing. This patch prevents that # situation too. # # A cast of many were involved in working this out, but in particular # Milton, Aneesh, Paul made key discoveries. # # Fixes: 0cef77c7798a7 ("powerpc/64s/radix: flush remote CPUs out of single-threaded mm_cpumask") # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Debugged-by: Milton Miller <miltonm@us.ibm.com> # Debugged-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Debugged-by: Paul Mackerras <paulus@samba.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20201126102530.691335-5-npiggin@gmail.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 01b0f0eae0812e80efeee4ee17687e5386335e08 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig CONFIG_SMP=y # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4120:warning: override: reassigning to symbol SMP # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/platforms/powermac/smp.c: In function 'smp_core99_cpu_disable': /kisskb/src/arch/powerpc/platforms/powermac/smp.c:914:2: error: implicit declaration of function 'cleanup_cpu_mmu_context' [-Werror=implicit-function-declaration] cleanup_cpu_mmu_context(); ^ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:283: arch/powerpc/platforms/powermac/smp.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:500: arch/powerpc/platforms/powermac] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:500: arch/powerpc/platforms] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1799: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:185: __sub-make] Error 2 Command 'make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_pmac32_defconfig+SMP_powerpc-gcc5 # Build took: 0:00:52.471073
