Subject: [RFC PATCH v2 43/69] KVM: x86/mmu: Allow non-zero init value for shadow PTE
Date: Fri,  2 Jul 2021 15:04:49 -0700	[thread overview]
Message-ID: <2a12f8867229459dba2da233bf7762cb1ac2722c.1625186503.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1625186503.git.isaku.yamahata@intel.com>

From: Sean Christopherson <sean.j.christopherson@intel.com>

TDX will run with EPT violation #VEs enabled, which means KVM needs to
set the "suppress #VE" bit in unused PTEs to avoid unintentionally
reflecting not-present EPT violations into the guest.
