Re: [Xen-devel] [PATCH FOR-4.5] xen: arm64: Handle memory banks which are not 1GB aligned

Hi Roy, I too observe the same issue. I have enabled uefi_debug (XEN) DOM0: bootconsole [uart0] enabled (XEN) DOM0: Memory limited to 512MB (XEN) DOM0: efi: Getting parameters from FDT: (XEN) DOM0: efi: System Table: 0x000000007fb79f18 (XEN) DOM0: efi: MemMap Address: 0x000000007a88c018 (XEN) DOM0: efi: MemMap Size: 0x000004e0 (XEN) DOM0: efi: MemMap Desc.

Xen has not mapped this table to Dom0?
