Subject: [RFC PATCH v6 064/104] KVM: TDX: Add helper assembly function to TDX vcpu
Date: Thu, 5 May 2022 11:14:58 -0700 [thread overview]
Message-ID: <f40b7827026d65963fea84d4af78cb1cbca85149.1651774250.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1651774250.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
TDX defines an API to run TDX vcpu with its own ABI. Define an assembly
helper function to run TDX vcpu to hide the special ABI so that C code can
call it with function call ABI.
