Which in # the case of PPC64 means the bypass mask and not a mask from an IOMMU table # which is shorter and slower to use due to map/unmap operations (especially # expensive on "pseries"). # # However the existing implementation ignores the possibility of bypassing # and returns the IOMMU table mask on the pseries platform which makes some # drivers (mpt3sas is one example) choose 32bit DMA even though bypass is # supported. The powernv platform sort of handles it by having a bigger # default window with a mask >=40 but it only works as drivers choose # 63/64bit if the required mask is >32 which is rather pointless. # # This reintroduces the bypass capability check to let drivers make # a better choice of the DMA mask. # # Fixes: f1565c24b596 ("powerpc: use the generic dma_ops_bypass mode") # Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> # Reviewed-by: Christoph Hellwig <hch@lst.de> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210930034454.95794-1-aik@ozlabs.ru # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 23c216b335d1fbd716076e8263b54a714ea3cf0e # < make -s -j 32 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- defconfig # < make -s -j 32 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 32 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 32 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/aarch64-linux/bin/aarch64-linux- /kisskb/src/scripts/dtc/include-prefixes/arm/bcm2711-rpi-4-b.dts:220.10-231.4: Warning (pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format error, expected "0,0" /kisskb/src/scripts/dtc/include-prefixes/arm/bcm2711-rpi-4-b.dts:220.10-231.4: Warning (pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format error, expected "0,0" /kisskb/src/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi:464.3-52: Warning (pci_device_reg): /pcie@f8000000/pcie@0,0:reg: PCI reg address is not configuration space /kisskb/src/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi:464.3-52: Warning (pci_device_reg): /pcie@f8000000/pcie@0,0:reg: PCI reg address is not configuration space /kisskb/src/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi:464.3-52: Warning (pci_device_reg): /pcie@f8000000/pcie@0,0:reg: PCI reg address is not configuration space /kisskb/src/arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi:464.3-52: Warning (pci_device_reg): /pcie@f8000000/pcie@0,0:reg: PCI reg address is not configuration space /kisskb/src/arch/arm64/kvm/hyp/nvhe/Makefile:58: FORCE prerequisite is missing Completed OK # rm -rf /kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc11 # Build took: 0:04:32.653366
