[Qemu-devel] [PATCH v3 1/2] i386: Add Intel Processor Trace feature support

2018-01-31 Thread Luwei Kang
From: Chao Peng Expose Intel Processor Trace feature to guest. To make Intel PT live migration safe and get same CPUID information with same CPU model on diffrent host. CPUID[14] is constant in this patch. Intel PT use EPT is first supported in IceLake, the CPUID[14] get on this machine as defau
