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 d0cf9b561ca97d5245bb9e0c4774b7fadd897d67 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mpc8555cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) arch/powerpc/boot/mpc8541cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) arch/powerpc/boot/mpc8548cds_32b.dtb: Warning (pci_bridge): /pcie@e000a000/pcie@0: missing bus-range for PCI bridge arch/powerpc/boot/mpc8548cds_32b.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4cdeb8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 11:24:47 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2509070 Bytes = 2450.26 kB = 2.39 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 11:24:48 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2534244 Bytes = 2474.85 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 11:24:48 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2533028 Bytes = 2473.66 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.17.0-rc2-gd0cf9b5 Created: Tue Apr 24 11:24:48 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2533024 Bytes = 2473.66 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 # Build took: 0:00:35.814905
