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-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 1e072bee33d09c62a975faab919a5be92d9538ab # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_52xx_lite5200b_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 52xx/lite5200b_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_52xx_lite5200b_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x4dd480) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4dd480) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4ccd68) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.17.0-rc1-g1e072be Created: Sat Apr 21 00:27:25 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2449348 Bytes = 2391.94 kB = 2.34 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc1-g1e072be Created: Sat Apr 21 00:27:25 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2472904 Bytes = 2414.95 kB = 2.36 MB Load Address: 00500000 Entry Point: 00500228 Image Name: Linux-4.17.0-rc1-g1e072be Created: Sat Apr 21 00:27:25 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2473086 Bytes = 2415.12 kB = 2.36 MB Load Address: 00500000 Entry Point: 00500228 Completed OK # rm -rf /kisskb/build/powerpc-fixes_52xx_lite5200b_defconfig_powerpc-5.3 # Build took: 0:00:21.190707
