Subject: [RFC PATCH 11/12] kvm/vmx/nested: Support CR4.KL in nested
Date: Mon, 25 Jan 2021 17:06:19 +0800 [thread overview]
Message-ID: <1611565580-47718-12-git-send-email-robert.hu@linux.intel.com> (raw)
In-Reply-To: <1611565580-47718-1-git-send-email-robert.hu@linux.intel.com>
Add CR4.KL in nested.msr.cr4_fixed1 when guest CPUID supports KeyLocker. So
that it can pass check when preparing vmcs02.
