Subject: [PATCH v3 00/13] iommu: Add PASID support to Arm SMMUv3
Date: Mon,  9 Dec 2019 19:05:01 +0100	[thread overview]
Message-ID: <20191209180514.272727-1-jean-philippe@linaro.org> (raw)

Add support for Substream ID and PASIDs to the SMMUv3 driver.
Changes since v2 [1]:

* Split preparatory work into patches 5, 6, 8 and 9.

* Added patch 1. Not strictly relevant, but since we're moving the DMA
  allocations and adding a new one, we might as well clean the flags
  first.

* Fixed a double free reported by Jonathan, and other small
  issues.

* Added patch 12. Upstream commit c6e9aefbf9db ("PCI/ATS: Remove unused
  PRI and PASID stubs") removed the unused PASID stubs. Since the SMMU
  driver can be built without PCI, the stubs are now needed.
