Hi, Keir,
The following patches refines Xen support for CPU Xsave/Xrestore
support. There are three patches included.
Patch 1/3:
Adding Xsave/Xrestore support for PV guests. Feature is exposed
via CPUID. XSETBV is trapped and emulated by Xen (via GP#).
Patch 2/3:
Expose AVX to guest OSs.
Patch 3/3:
Adding guest save/restore support when Xsave/Xrestore are available.
Adding a pair of hypercalls for PV guest
Adding a new data chunk for HVM guest.
These are version 3 of the patch series.
Shan Haitao
