And # hence fails to assign offsets and shifts correctly (such as in L4 to # PGDIR offset calculation in makedumpfile). # # For getting the MMU, makedumpfile uses `cur_cpu_spec.mmu_features`. # # Add `cur_cpu_spec` symbol and offset of `mmu_features` in the `cpu_spec` # struct, to VMCOREINFO, so that makedumpfile can assign the offsets # correctly, without needing a VMLINUX. # # Also, even along with `cur_cpu_spec->mmu_features` makedumpfile has to # depend on the 'MMU_FTR_TYPE_RADIX' flag in mmu_features, implying kernel # developers need to be cautious of changes to 'MMU_FTR_*' defines. # # A more stable approach was suggested in the below thread by contributors: # https://lore.kernel.org/linuxppc-dev/20230920105706.853626-1-adityag@linux.ibm.com/ # # The suggestion was to add whether 'RADIX_MMU' is enabled in vmcoreinfo # # This patch also implements the suggestion, by adding 'RADIX_MMU' in # vmcoreinfo, which makedumpfile can use to get whether the crashed system # had RADIX MMU (in which case 'NUMBER(RADIX_MMU)=1') or not (in which # case 'NUMBER(RADIX_MMU)=0') # # Fixes: 368a0590d954 ("powerpc/book3s64/vmemmap: switch radix to use a different vmemmap handling function") # Reported-by: Sachin Sant <sachinp@linux.ibm.com> # Signed-off-by: Aditya Gupta <adityag@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/20231023072612.50874-1-adityag@linux.ibm.com # < /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 36e826b568e412f61d68fedc02a67b4d8b7583cc # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc86xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc86xx_defconfig Using /kisskb/src/arch/powerpc/configs/mpc86xx_base.config as base Merging /kisskb/src/arch/powerpc/configs/86xx-hw.config Merging /kisskb/src/arch/powerpc/configs/fsl-emb-nonhw.config # # merged configuration written to .config (needs make) # # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc86xx_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-next_mpc86xx_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-next_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-next_mpc86xx_defconfig_powerpc-gcc5 # Build took: 0:01:12.502970
