Subject: [PATCH v6 0/5] iommu aux-domain APIs extensions
Date: Fri, 30 Oct 2020 12:58:04 +0800 [thread overview]
Message-ID: <20201030045809.957927-1-baolu.lu@linux.intel.com> (raw)
Hi Joerg and Alex,
A description of purpose for this series could be found here.
https://lore.kernel.org/linux-iommu/20200901033422.22249-1-baolu.lu@linux.intel.com/
The previous version was posted here.
https://lore.kernel.org/linux-iommu/20200922061042.31633-1-baolu.lu@linux.intel.com/
This version is evolved according to Joerg's comments posted here.
https://lore.kernel.org/linux-iommu/20200924095532.GK27174@8bytes.org/
This basic idea is that IOMMU registers an iommu_ops for subdevice
bus (for example, the vfio/mdev bus), so that the upper layer device
passthrough framework could use the standard iommu-core code to setup
the IOMMU logistics.
This series was tested by Dave Jiang <dave.jiang@intel.com> with his
idxd driver posted here. Very appreciated!

Please help to review and comment.
Best regards,
baolu
