[Xen-devel] [PATCH 1/5] [POST-4.0]: HVM NUMA guest: generate SRAT table
The attached patch extends the hvm_info_table to include NUMA topology information. The hvmloader will read these entries and will generate an appropriate ACPI SRAT table. For now the information is zeroed in libxc, so that the SRAT generation will be skipped until activated in a later patch. (At least) Linux seems to be quite picky about the SRAT table, "odd" memory borders will crash it early. I am not sure whether sanity checks should be introduced here in the hvmloader or in libxc.
