Subject: [PATCH 0/2] iommu: request CSR space
Date: Fri, 18 May 2012 17:18:26 -0600 [thread overview]
Message-ID: <20120518231238.31187.44571.stgit@bhelgaas.mtv.corp.google.com> (raw)
This adds a request_mem_region() for the DRHD registers. The AMD
code has similar code in iommu_map_mmio_space().
This helps avoid address conflicts when assigning PCI BARs.
