Subject: [PATCH 01/14] iommu: Add DOMAIN_ATTR_ENABLE_TTBR1
Date: Wed, 21 Feb 2018 15:59:11 -0700 [thread overview]
Message-ID: <20180221225924.30737-2-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20180221225924.30737-1-jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
Add a new domain attribute to enable the TTBR1 pagetable for drivers
and devices that support it. This will enabled using a TTBR1 (otherwise
known as a "global" or "system" pagetable for devices that support a split
pagetable scheme for switching pagetables quickly and safely.
