Subject: [PATCH v2 0/8] iommu: Add PASID support to Arm SMMUv3
Date: Fri,  8 Nov 2019 16:25:00 +0100	[thread overview]
Message-ID: <20191108152508.4039168-1-jean-philippe@linaro.org> (raw)

This is version 2 of the series I sent a while ago [1], adding PASID
support to the Arm SMMUv3 driver.

Changes since v1:
* Dropped the patch adding auxiliary domain support. It's an easy way to
  test PASID, by populating PASID contexts using iommu_map/unmap(), but
  I don't know if it will ever have real users. 

  Since v1 I changed my testing gear, and am using the zip accelerator
  [2] instead of a software model. It only uses SVA and testing
  auxiliary domains would require additional changes that would never go
  upstream. SVA requires another 20 patches (including I/O page faults)
  that I will send later, but at least I know that this will get used.

* ioasid patch has been carried by Jacob and should be merged for v5.5 [3]

* Split patch "Add support for Substream IDs" into patches 4 and 5.

* Added IORT support (patch 3) and addressed other comments.
