The compilers # provided by the major distros (Fedora, Ubuntu) default to 128-bits and # are not affected by the build failure. # # There is a compiler flag to force 128-bit long double, which may be the # correct long term fix, but as an interim fix only allow building the DCN # driver if long double is 128-bits by default. # # The bisection in commit d11219ad53dc must have gone off the rails at # some point, the build failure occurs all the way back to the original # commit that enabled DCN support on powerpc, at least with some # toolchains. # # Depends-on: d11219ad53dc ("amdgpu: disable powerpc support for the newer display engine") # Fixes: 16a9dea110a6 ("amdgpu: Enable initial DCN support on POWER") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Acked-by: Alex Deucher <alexander.deucher@amd.com> # Reviewed-by: Dan HorĂ¡k <dan@danny.cz> # Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2100 # Link: https://lore.kernel.org/r/20220725123918.1903255-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 c653c591789b3acfa4bf6ae45d5af4f330e50a91 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc86xx_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/fsl/mvme7100.dts:135.22-137.4: Warning (pci_bridge): /pcie@f1008000: missing ranges for PCI bridge (or not a bridge) also defined at /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8641si-post.dtsi:92.7-117.3 /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8641si-post.dtsi:102.9-116.4: Warning (pci_bridge): /pcie@f1008000/pcie@0: missing ranges for PCI bridge (or not a bridge) /kisskb/src/arch/powerpc/boot/dts/fsl/mvme7100.dts:139.22-141.4: Warning (pci_bridge): /pcie@f1009000: missing ranges for PCI bridge (or not a bridge) also defined at /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8641si-post.dtsi:119.7-144.3 /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8641si-post.dtsi:129.9-143.4: Warning (pci_bridge): /pcie@f1009000/pcie@0: missing ranges for PCI bridge (or not a bridge) arch/powerpc/boot/dts/fsl/mvme7100.dtb: Warning (unit_address_format): Failed prerequisite 'pci_bridge' arch/powerpc/boot/dts/fsl/mvme7100.dtb: Warning (pci_device_reg): Failed prerequisite 'pci_bridge' arch/powerpc/boot/dts/fsl/mvme7100.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' /kisskb/src/arch/powerpc/boot/dts/fsl/mvme7100.dts:30.11-32.6: Warning (i2c_bus_reg): /soc@f1000000/i2c@3000/rtc@68: missing or empty reg property Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-gcc5 # Build took: 0:01:12.804692
