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> # Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2100 # < /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 50d2a40f2caac5bb31627ee20039e74332bd0d8a # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_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/mpc8541cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:31.338977
