Subject: [PATCH v11 04/12] iommu: Add a domain attribute to get/set a pagetable configuration
Date: Mon, 3 Aug 2020 13:35:39 -0600 [thread overview]
Message-ID: <20200803193547.305660-5-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200803193547.305660-1-jcrouse@codeaurora.org>
Add domain attribute DOMAIN_ATTR_PGTABLE_CFG. This will be used by
arm-smmu to share the current pagetable configuration with the
leaf driver and to allow the leaf driver to set up a new pagetable
configuration under certain circumstances.
