This can # result in contention of ATSD registers leading to soft lockups on some # threads, particularly when invalidating a large address range in # pnv_npu2_mn_invalidate_range(). # # At some threshold it becomes more efficient to flush the entire GPU # TLB for the given MM context (PID) than individually flushing each # address in the range. This patch will result in ranges greater than # 2MB being converted from 32+ ATSDs into a single ATSD which will flush # the TLB for the given PID on each GPU. # # Fixes: 1ab66d1fbada ("powerpc/powernv: Introduce address translation services for Nvlink2") # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Alistair Popple <alistair@popple.id.au> # Acked-by: Balbir Singh <bsingharora@gmail.com> # Tested-by: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 1e072bee33d09c62a975faab919a5be92d9538ab # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- pseries_le_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig+NO_NUMA_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 3 section mismatch(es).
