Subject: [PATCH v18 087/121] KVM: TDX: Add a place holder to handle TDX VM exit
Date: Mon, 22 Jan 2024 15:54:03 -0800 [thread overview]
Message-ID: <b4350d9d652551eb8f7d93d29ffe9e2a0120ef99.1705965635.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1705965634.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.
