From 090cd45b21cd0d26297315d4bd9b83d9dcad10e1 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 14 Jun 2022 20:07:05 +0000 Subject: KVM: selftests: Clean up requirements for XFD-aware XSAVE features Provide informative error messages for the various checks related to requesting access to XSAVE features that are buried behind XSAVE Feature Disabling (XFD). Opportunistically rename the helper to have "require" in the name so that it's somewhat obvious that the helper may skip the test.
