From 382409b4c43e5b44ae4a869ff793d3cf01d12004 Mon Sep 17 00:00:00 2001 From: Jim Mattson Date: Wed, 27 Mar 2019 13:15:37 -0700 Subject: kvm: x86: Include CPUID leaf 0x8000001e in kvm's supported CPUID Kvm now supports extended CPUID functions through 0x8000001f. CPUID leaf 0x8000001e is AMD's Processor Topology Information leaf. This contains similar information to CPUID leaf 0xb (Intel's Extended Topology Enumeration leaf), and should be included in the output of KVM_GET_SUPPORTED_CPUID, even though userspace is likely to override some of this information based upon the configuration of the particular VM.
