Subject: [PATCH v7 083/102] KVM: TDX: Add a place holder to handle TDX VM exit
Date: Mon, 27 Jun 2022 14:54:15 -0700 [thread overview]
Message-ID: <67130af96c1c92b37cc048401c3a1a5192070a96.1656366338.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1656366337.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
Wire up handle_exit and handle_exit_irqoff methods and add a place holder
to handle VM exit. Add helper functions to get exit info, exit
qualification, etc.
