Subject: [PATCH 0/3] Add support for ACPI VIOT
Date: Tue, 16 Mar 2021 20:16:50 +0100 [thread overview]
Message-ID: <20210316191652.3401335-1-jean-philippe@linaro.org> (raw)
Add a driver for the ACPI VIOT table, which enables virtio-iommu on
non-devicetree platforms, including x86. This series depends on the
ACPICA changes of patch 1, which will be included in next release [1]
and pulled into Linux.
The Virtual I/O Translation table (VIOT) describes the topology of
para-virtual I/O translation devices and the endpoints they manage.
It was recently approved for inclusion into the ACPI standard [2].
A provisional version of the specification can be found at [3].
After discussing non-devicetree support for virtio-iommu at length
[4][5][6] we concluded that it should use this new ACPI table. And for
platforms that don't implement either devicetree or ACPI, a structure
that uses roughly the same format [6] can be built into the device.
