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!

https://lore.kernel.org/lkml/160021250454.67751.3119489448651243709.stgit@djiang5-desk3.ch.intel.com/

Please help to review and comment.

Best regards,
baolu
