Hi Linus,

Please pull these IOMMU updates for v6.11.

I've been looking after the IOMMU tree in Joerg's absence [1] for the
past few weeks and I was expecting him back at the start of this week to
send the pull. However, I've not heard from him at all and figured that
I may as well send this now rather than wait until the second week of
the merge window.

A few minor fixes have started showing up too, so I may end up sending
you a follow-up next week anyway.

A summary of all the changes is included in the tag.

Cheers,

Will

Merge branch 'iommu/iommufd/paging-domain-alloc' into iommu/next (2024-07-12 16:57:47 +0100)

----------------------------------------------------------------
IOMMU Updates for Linux v6.11

- Core:
* Support for the "ats-supported" device-tree property.

* Removal of the 'ops' field from 'struct iommu_fwspec'.

* Introduction of iommu_paging_domain_alloc() and partial conversion
of existing users.

* Introduce 'struct iommu_attach_handle' and provide corresponding
IOMMU interfaces which will be used by the IOMMUFD subsystem.

* Remove stale documentation.

* Add missing MODULE_DESCRIPTION() macro.

* Misc cleanups.

- Allwinner Sun50i:
* Ensure bypass mode is disabled on H616 SoCs.

* Ensure page-tables are allocated below 4GiB for the 32-bit
page-table walker.

* Add new device-tree compatible strings.

- AMD Vi:
* Use try_cmpxchg64() instead of cmpxchg64() when updating pte.

- Arm SMMUv2:
* Print much more useful information on context faults.

* Fix Qualcomm TBU probing when CONFIG_ARM_SMMU_QCOM_DEBUG=n.

* Add new Qualcomm device-tree bindings.

- Arm SMMUv3:
* Support for hardware update of access/dirty bits and reporting via
IOMMUFD.

* More driver rework from Jason, this time updating the PASID/SVA support
to prepare for full IOMMUFD support.

* Add missing MODULE_DESCRIPTION() macro.

* Minor fixes and cleanups.

- NVIDIA Tegra:

* Fix for benign fwspec initialisation issue exposed by rework on the
core branch.

- Intel VT-d:

* Use try_cmpxchg64() instead of cmpxchg64() when updating pte.

* Use READ_ONCE() to read volatile descriptor status.

* Remove support for handling Execute-Requested requests.

* Avoid calling iommu_domain_alloc().

* Minor fixes and refactoring.

- Qualcomm MSM:

* Updates to the device-tree bindings.
