Subject: [PATCH v5 08/12] iommu/vt-d: Pass pasid table to context mapping
Date: Wed, 28 Nov 2018 11:54:45 +0800 [thread overview]
Message-ID: <20181128035449.10226-9-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20181128035449.10226-1-baolu.lu@linux.intel.com>
So that the pasid related info, such as the pasid table and the
maximum of pasid could be used during setting up scalable mode
context.
