[Xen-devel] [VTD][PATCH] Only setup rmrr identity mappings of the assigned devices
Current implementation setups identity mappings for all the rmrrs whether the assigned device has rmrr or not. It''s wasteful and not necessary, because only USB controllers and UMA integarated graphics devices have rmrr. This patch only setups rmrr identity mappings of the assigned devices. If the assigned devices don''t have rmrr, needn''t to setup rmrr identity mapping for guest. BTW, this patch fixes the VT-d bug (Fail to boot smp Linux guest with VT-d NIC assigned on IA32e platform).
