Subject: [PATCH v8 05/13] arm/mem_access: Introduce GV2M_EXEC permission
Date: Wed, 9 Aug 2017 10:20:30 +0200 [thread overview]
Message-ID: <20170809082038.3236-6-proskurin@sec.in.tum.de> (raw)
In-Reply-To: <20170809082038.3236-1-proskurin@sec.in.tum.de>
We extend the current implementation by an additional permission,
GV2M_EXEC, which will be used to describe execute permissions of PTE's
as part of our guest translation table walk implementation.
