Hi Guangrong,
How about also add SGX to Skylake?
Thanks,

From: Eduardo Habkost <ehabkost@xxxxxxxxxx>
Introduce Skylake-Client cpu mode which inherits the features from
Broadwell and supports some additional features that are: MPX,
XSAVEC, XSAVES and XGETBV1
Note:
1. 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. We will post out the patch introducing Skylake-Server mode once it
has been verified on a Skylake Sever machine
[ Xiao: largely based on Eduardo's work, introduce Skylake-Client and
Skylake-Server cpu modes separately. ]
