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") #
