Since x86 also supports VMEMMAP the same approach should work on x86. In fact most platforms use VMMEMMAP: cl@eng07sys-r113:~/linux$ grep VMEMMAP_ENABLE arch/*/Kconfig* arch/arm64/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE arch/loongarch/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE arch/powerpc/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE arch/riscv/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE if 64BIT arch/s390/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE arch/sparc/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE arch/x86/Kconfig: select SPARSEMEM_VMEMMAP_ENABLE if X86_64 Can the crash code be generalized so that it works on all platforms? -- Crash-utility mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxxxxxx https://${domain_name}/admin/lists/devel.lists.crash-utility.osci.io/ Contribution Guidelines: https://github.com/crash-utility/crash/wiki
