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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < git log --format=%s --max-count=1 d0cf9b561ca97d5245bb9e0c4774b7fadd897d67 # < make -s -j 10 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 10 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- FIT description: Linux 4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 10:04:13 2018 Image 0 (kernel@0) Description: Linux 4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 10:04:13 2018 Type: Kernel Image Compression: gzip compressed Data Size: 4457010 Bytes = 4352.55 kB = 4.25 MB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x808905c0 Hash algo: sha1 Hash value: e8f5701ed68decd9bd80e4dac02da6ef43eef47a Image 1 (fdt@boston) Description: img,boston Device Tree Created: Tue Apr 24 10:04:13 2018 Type: Flat Device Tree Compression: uncompressed Data Size: 3668 Bytes = 3.58 kB = 0.00 MB Architecture: MIPS Hash algo: sha1 Hash value: 569c37cc891ce1e1f3a193cb41cc691a5d2debb5 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Tue Apr 24 10:04:13 2018 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 kB = 0.00 MB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Completed OK # rm -rf /kisskb/build/powerpc-fixes_mips-defconfig_mipsel # Build took: 0:02:07.111962
