Subject: [PATCH v2 0/6] Add support for ACPI VIOT
Date: Fri, 23 Apr 2021 13:38:31 +0200 [thread overview]
Message-ID: <20210423113836.3974972-1-jean-philippe@linaro.org> (raw)
Add a driver for the ACPI VIOT table, which provides topology
information for para-virtual platforms. Enable virtio-iommu on
non-devicetree platforms, including x86.
Since v1 [1]:
* The VIOT header definitions have been picked for v5.13
* Share more code with IORT. Patches 1 and 2 extract the common code
from IORT.
* Simplify the VIOT driver. Use the existing fwnode infrastructure
instead of adding hooks to the IOMMU driver.
You can find a QEMU implementation at [2], with extra support for
testing all VIOT nodes including MMIO-based endpoints and IOMMU. This
series, based on linux-next, is at [3]
