- ARM SMMUv2:
- Device-tree binding updates for Qualcomm Eliza, Maili, Shikra and
IPQ9650 SoCs.
- Add support for Qualcomm SM8450.
- Numerous fixes for lifetime and ordering issues found by Sashiko in
the Qualcomm driver.
- ARM SMMUv3:
- Fix interrupt type in device-tree binding example for NVIDIA CMDQV.
- Numerous fixes for issues identified by Sashiko in the NVIDIA CMDQV
driver.
- Work around TLB erratum T264-SMMU-3 on Tegra264 by repeating the
invalidation sequence.
- Add support for HAFT (hardware access flag in table entries) when
using SVA.
- Probe for 52-bit addressing with a page size smaller than 64k ('DS')
but don't do anything with it for now.
- Minor driver improvements (remove sort_nonatomic(), use
readl_relaxed_poll_timeout_atomic(), fix IOPF teardown ordering).
- Intel VT-d:
- Consolidation of complex enablement logic into a clean, priority-based
state machine.
- Support for the DMA_REMAP_OPT_OUT flag from the VT-d v5.2
specification.
- An update to cache_tag_flush_devtlb_psi() to use full-range constants
instead of modifying shared variables for CACHE_TAG_NESTING_DEVTLB.
- A fix for the UCTP context-table slot when copying root entries.
- Fixes for several pre-existing issues reported by Sashiko.
- General code cleanup and refinement.
- AMD IOMMU:
- Add SNP page-mode-0 support, enabling passthrough, v2 DMA page
tables and host SVA on supporting systems.
- Fix invalid PPR handling, COMPLETE_PPR responses and guest-mode
reporting.
- Improve Southbridge IOAPIC validation and remove the dependency on
hard-coded device IDs.
- Fix PCI-device lifetime, debugfs and diagnostic issues.
- IOMMU core and IOMMUFD:
- Restore serialization of the shared MSI-page list.
- Fix SVA-handle publication and several IOMMUFD reference and error
path leaks.
- Return the expected zero result for invalid generic page-table
translations.
- Allocate per-CPU IOVA magazines lazily to reduce memory use on
large systems.
- PCI ATS:
- Make VF support checks account for the associated PF and validate
that VF and PF Smallest Translation Unit settings agree.
- Platform drivers:
- Fix Qualcomm runtime-PM, probe unwind, fault reporting and page
table initialization races.
- Rework Rockchip state handling and fix clock, probe and stale-fault
handling.
- Fix smaller issues in the MSM and MediaTek drivers.
- Device-tree bindings:
- Add new Qualcomm SMMU compatibles, convert the OMAP IOMMU binding
to YAML, and fix the Tegra264 CMDQV interrupt example.
- Various smaller cleanups, documentation fixes and a Rust IOMMU
safety/readability improvement.
