[Xen-devel] about: XENMEM_machphys_mfn_list

[Lin.Yu <yulin724@xxxxxxxxx>]

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?
