[Ques]:xen_ident_map_ISA ant it's mfns...
Hi, I am bit confused about the do_update_va_mapping call that dom0 makes in xen_ident_map_ISA() to map ffff8800000a0000 to mfn a0. The mfn belongs to DOMID_IO. Before the mfn is mapped, the l1 entry is not empty: 0000000139d08500: 00100001380a0027 After the mapping: 0000000139d08500: 00100000000a0467 as expected. However, the mfn 1380a0 still seems to belong to dom0. Shouldn''t that have been returned back to the xen heap? thanks, Mukesh
