Subject: [PATCH v8 0/7] Add virtio-iommu driver
Date: Thu, 30 May 2019 18:09:22 +0100	[thread overview]
Message-ID: <20190530170929.19366-1-jean-philippe.brucker@arm.com> (raw)

Implement the virtio-iommu driver, following specification v0.12 [1].
Since last version [2] we've worked on improving the specification,
which resulted in the following changes to the interface:
* Remove the EXEC flag.
* Add feature bit for the MMIO flag.
* Change domain_bits to domain_range.

Given that there were small changes to patch 5/7, I removed the review
and test tags. Please find the code at [3].
