[Crash-utility] Re: [PATCH v4] arm64: Add vmemmap support

Hi Christopher, Just to add to this, vmemmap_list (basically a list of page structs) may be missing/empty on some architectures, such as PowerPC. There was a commit in Linux to simplify the mapping by using page table instead of vmemmap_list, in case of Radix MMU on PowerPC: 368a0590d954: (powerpc/book3s64/vmemmap: switch radix to use a different vmemmap handling function) Accordingly, a improvement was done in crash to handle this: a9291fc1bf61 ("ppc64: do page traversal if vmemmap_list not populated") We might need to handle such case if it's generalized.
