  • Thread-topic: [Xen-devel][PATCH 0/2] Enhance MTRR/PAT virtualization for EPT & VT-d enabled both

The enhancement includes 2 patches.

The first one is to use the GUEST_PAT and HOST_PAT VMCS area. The one is a resending patch before.

The second one is to set the effective EPT memory type according to the VT-d snoop control capability.

There are also some cleans up included.

 

Thanks

Xiaohui
