No, i am afraid it is not a Skylake Client feature. On 04/29/2016 11:11 AM, Huang, Kai wrote:
Hi Guangrong, How about also add SGX to Skylake?

As XSAVES is disabled in upstream linux kernel by commit e88221c50 (x86/fpu: Disable XSAVES* support for now), QEMU will complain about "warning: host doesn't support requested feature: CPUID.0DH:EAX.xsaves [bit 3]" 2.
