XSAVE/XRSTOR manages the existing and future processor extended states on x86 architecture. The XSAVE/XRSTOR infrastructure is defined in Intel SDMs: http://www.intel.com/products/processor/manuals/ The patch uses the classical CR0.TS based algorithm to manage the states on context switch. At present, we know 3 bits in the XFEATURE_ENABLED_MASK: FPU, SSE and YMM. YMM is defined in Intel AVX Programming Reference: http://software.intel.com/sites/avx/ One more patch to support hvm guest's save/restore by defining a pair of new HVM_REGISTER_SAVE_RESTORE save/load handlers will be posted later. Thanks, -- Dexuan Attachment:
