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-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 d0cf9b561ca97d5245bb9e0c4774b7fadd897d67 # < make -s -j 10 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 10 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@1,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@2,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@3,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/arm64/boot/dts/qcom/apq8096-db820c.dtb: Warning (pci_bridge): /soc/agnoc@0/qcom,pcie@610000: node name is not "pci" or "pcie" arch/arm64/boot/dts/qcom/apq8096-db820c.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/arm64/boot/dts/qcom/msm8996-mtp.dtb: Warning (pci_bridge): /soc/agnoc@0/qcom,pcie@610000: node name is not "pci" or "pcie" arch/arm64/boot/dts/qcom/msm8996-mtp.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' Completed OK # rm -rf /kisskb/build/powerpc-fixes_arm64-defconfig_arm64 # Build took: 0:04:15.948650
