Hi, all,
XENMEM_machphys_mfn_list command is used to acquire the mapping between the pseudo-physical to machine. And the hypercall will fill in the struct xen_machphys_mfn_list. I do not understand "This table is an array of pseudo-physical frame numbers of the start of 2MB extents, corresponding to 2MB rangs in the pseudo-physical address space". "This table" means the array pointed by xen_machphys_mfn_list.extent_start. I am reading the code about this struct, still in confusion. :-) Who can help me? -- Best Regards, -- Lin.Yu _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
