We emulate a few SSE instructions, like MOVQ. Just enough for emulation of things like optimised memcpy() and memset() when applied to emulated device mmio areas. We don't plan to fully emulate all SSE instructions. Xen doesn't really need it and it would greatly increase the size and complexity of the emulator. If there is a genuine good reason, however, I might reconsider. -- Keir On 03/02/2010 18:50, "sanjay kushwaha" <sanjay.kushwaha@xxxxxxxxx> wrote: > I am using Xen-3.4.2rc1 and I notice that it doesnt have support for emulating > IA-32 SSE instructions. > > Can someone please tell me if SSE instruction emulation is planned in a future > version or is already supported in some version of Xen? > > Thanks, > Sanjay _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
