Subject: [RFC PATCH v1 04/15] iommu: Add DOMAIN_ATTR_PTBASE
Date: Fri, 1 Mar 2019 12:38:26 -0700 [thread overview]
Message-ID: <1551469117-3404-5-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1551469117-3404-1-git-send-email-jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
Add an attribute to return the base address of the pagetable. This is used
by auxiliary domains from arm-smmu to return the address of the pagetable
to the leaf driver so that it can set the appropriate pagetable through
it's own means.
