Thread-topic: [Xen-devel] [Patch] Adding back CPUID support for Xsave

Thanks, this looks better. I have some further questions however. You appear to only be exposing XSAVE to PV guests -- Why is that? Also, the patch passes the AVX feature unconditionally through to HVM guests -- firstly, why only visible HVM guests; and secondly, should it not be conditional on XSAVE support in the hypervisor (don't we need XSAVE to be able to save/restore AVX state)? -- Keir On 09/11/2010 02:31, "Haitao Shan" <maillists.shan@xxxxxxxxx> wrote: > Hi, Keir, > > This patch adds back the reverted CPUID support for XSAVE feature.
