Subject: [PATCH v8 065/103] KVM: TDX: vcpu_run: save/restore host state(host kernel gs)
Date: Sun, 7 Aug 2022 15:01:50 -0700 [thread overview]
Message-ID: <f0708d549ded36e8b6bfc13e8fd34fb09244b7bd.1659854790.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1659854790.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
On entering/exiting TDX vcpu, Preserved or clobbered CPU state is different
from VMX case. Add TDX hooks to save/restore host/guest CPU state.
Save/restore kernel GS base MSR.
