Subject: [PATCH v4 0/7] Add virtio-iommu driver
Date: Thu, 15 Nov 2018 16:52:27 +0000	[thread overview]
Message-ID: <20181115165234.43990-1-jean-philippe.brucker@arm.com> (raw)

Implement the virtio-iommu driver, following specification v0.8 [1].

Changes since v3 [2]:
* Rebase onto v4.20-rc2. Patch 3 now touches drivers/of/base.c instead
  of drivers/pci/of.c, since the map_rid() function has moved.
* Removed the request timeout, that depended on DEBUG.
* Other small fixes addressing comments on v3.

You can find Linux driver and kvmtool device on my virtio-iommu/v0.8.1
branches [3]. You can also test it with the latest version of Eric's
QEMU device [4].
