From 50bc913d526beb9937f1eb0159ec63c43234f961 Mon Sep 17 00:00:00 2001 From: David Matlack Date: Wed, 19 May 2021 21:13:45 +0000 Subject: [PATCH] KVM: selftests: Ignore CPUID.0DH.1H in get_cpuid_test Similar to CPUID.0DH.0H this entry depends on the vCPU's XCR0 register and IA32_XSS MSR. Since this test does not control for either before assigning the vCPU's CPUID, these entries will not necessarily match the supported CPUID exposed by KVM. This fixes get_cpuid_test on Cascade Lake CPUs.
