Subject: [PATCH v2 0/3] iommu/amd: I/O VA address limits
Date: Wed, 1 Jul 2020 00:46:31 +0200 [thread overview]
Message-ID: <20200630224634.319-1-sebott@amazon.de> (raw)
In-Reply-To: <20200630093039.GC28824@8bytes.org>
The IVRS ACPI table specifies maximum address sizes for I/O virtual
addresses that can be handled by the IOMMUs in the system. Parse that
data from the IVRS header to provide aperture information for DMA
mappings and users of the iommu API.
Changes for V2:
- use limits in iommu_setup_dma_ops()
- rebased to current upstream
Sebastian Ott (3):
iommu/amd: Parse supported address sizes from IVRS
iommu/amd: Restrict aperture for domains to conform with IVRS
iommu/amd: Actually enforce geometry aperture
