[PATCH v8 0/8] SMMU handling for PCIe Passthrough on ARM
Posted by Mykyta Poturai 12 months ago
This series introduces SMMU handling for PCIe passthrough on ARM. These patches
should be able to be upstreamed independently from the vPCI series [1]. See [2]
for notes about test cases.

[2] https://lists.xenproject.org/archives/html/xen-devel/2023-06/msg01135.html

v7-v8:
* no changes

v6->v7:
* drop ("xen/arm: don't pass iommu properties to hwdom for iommu-map")

v5->v6:
* don't revert ("xen/arm: Add cmdline boot option "pci-passthrough = <boolean>"")
* add ("xen/arm: enable dom0 to use PCI devices with pci-passthrough=no")

v4->v5:
* drop ("xen/arm: Improve readability of check for registered devices")
* drop ("xen/arm: Move is_protected flag to struct device")
* add ("xen/arm: don't pass iommu properties to hwdom for iommu-map")
* add ("xen/arm: Fix mapping for PCI bridge mmio region")
* revert ("xen/arm: Add cmdline boot option "pci-passthrough = <boolean>"")
* add ("xen/arm: Map ITS doorbell register to IOMMU page tables.")
* fix test case #1 with PCI device in dom0

v3->v4:
* split a change from ("xen/arm: Move is_protected flag to struct device") into
  a new separate patch
* see individual patches for further details

v2->v3:
* drop "pci/arm: Use iommu_add_dt_pci_device()"
* drop "RFC: pci/arm: don't do iommu call for phantom functions"
* move invocation of sideband ID mapping function to add_device()
  platform_ops/iommu_ops hook

And why exactly was this posted then as a new version?

That is supposed to mean there are no changes in the series's structure, 
only in the individual patches. Sorry for possible confusion, I will try 
to write something clearer next time.
