Subject: [PATCH v5 0/5] Add support for ACPI VIOT
Date: Fri, 18 Jun 2021 17:20:55 +0200 [thread overview]
Message-ID: <20210618152059.1194210-1-jean-philippe@linaro.org> (raw)
Add a driver for the ACPI VIOT table, which provides topology
information for para-virtual IOMMUs. Enable virtio-iommu on
non-devicetree platforms, including x86.
Since v4 [1]:
* Fixes (comments, wrong argument, unused variable)
* Removed patch 5 that wrongly moved set_dma_ops(dev, NULL) into dma-iommu.
The simplification of limit parameters for x86 callers is now in patch 4.
* Release ACPI table after parsing
* Added review and tested tags, thanks for all the feedback!
You can find a QEMU implementation at [2], with extra support for
testing all VIOT nodes including MMIO-based endpoints and IOMMU.
This series is at [3].
