Subject: [PATCH v8 094/103] KVM: TDX: Implement callbacks for MSR operations for TDX
Date: Sun, 7 Aug 2022 15:02:19 -0700 [thread overview]
Message-ID: <820c1fb0684b95fa45db15512ecdb4ee22743647.1659854791.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1659854790.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
Implements set_msr/get_msr/has_emulated_msr methods for TDX to handle
hypercall from guest TD for paravirtualized rdmsr and wrmsr. The TDX
module virtualizes MSRs. For some MSRs, it injects #VE to the guest TD
upon RDMSR or WRMSR. The exact list of such MSRs are defined in the spec.
Upon #VE, the guest TD may execute hypercalls,
TDG.VP.VMCALL<INSTRUCTION.RDMSR> and TDG.VP.VMCALL<INSTRUCTION.WRMSR>,
which are defined in GHCI (Guest-Host Communication Interface) so that the
host VMM (e.g. KVM) can virtualizes the MSRs.
