As I think the implementation is right, the former will need updating. Do you actually need a HVM domain to be able to XENMEM_set_memory_map
Yes. Actually we need to enable two hypercalls here, #1. XENMEM_set_memory_map --> Set #2. XENMEM_memory_map --> Get
on itself? If not, it should probably replace XENMEM_memory_map here.
Just rephrase, xen: enable XENMEM set/get memory_map in hvm This patch enables XENMEM_set_memory_map in hvm and then we can use it to setup the e820 mappings, and finally hvmloader can get these mappings with XENMEM_memory_map.
