Subject: [PATCH 1/2] iommu: add IOMMU_PRIV flag for access-protected mappings
Date: Wed, 17 Sep 2014 13:16:08 -0700 [thread overview]
Message-ID: <1410984969-2340-2-git-send-email-mitchelh@codeaurora.org> (raw)
In-Reply-To: <1410984969-2340-1-git-send-email-mitchelh-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
Some IOMMUs support access-protected mappings. Add a mapping flag to
indicate that the mapping should be created with access protection
configured.
