From 52297436199dde85be557ee6bc779f5b96082f74 Mon Sep 17 00:00:00 2001 From: Aaron Lewis Date: Mon, 21 Oct 2019 16:30:27 -0700 Subject: [PATCH] kvm: svm: Update svm_xsaves_supported AMD CPUs now support XSAVES in a limited fashion (they require IA32_XSS to be zero). AMD has no equivalent of Intel's "Enable XSAVES/XRSTORS" VM-execution control. Instead, XSAVES is always available to the guest when supported on the host.
