Subject: [RFC PATCH v6 042/104] KVM: VMX: Introduce test mode related to EPT violation VE
Date: Thu, 5 May 2022 11:14:36 -0700 [thread overview]
Message-ID: <055cf7f4120e5dece70552fab1576ace8bb047ee.1651774250.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1651774250.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
To support TDX, KVM is enhanced to operate with #VE. For TDX, KVM programs
to inject #VE conditionally and set #VE suppress bit in EPT entry. For VMX
case, #VE isn't used. If #VE happens for VMX, it's a bug. To be
defensive (test that VMX case isn't broken), introduce option
ept_violation_ve_test and when it's set, set error.
