This prevents samples piling up around interrupt # enable (hard enable or interrupt replay via soft enable) in PMUs / modes # where the PR sample indication is not in synch with SIAR. # # This results in better sampling of interrupt entry and exit in particular. # # Signed-off-by: Nicholas Piggin # Tested-by: Athira Rajeev # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20210720141504.420110-1-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 03182211c6e6458ef67ee66ed4c71c8ff7791a2d # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/walnut_defconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_walnut_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_40x_walnut_defconfig_powerpc-gcc5 # Build took: 0:00:48.014657
