Hi Joerg,
The following changes are queued for v7.3-rc1. This update introduces
new features, quick fixes and several refactorings, including:
- 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.
These patches are based on v7.2-rc6. The full series is also available
on GitHub:
https://github.com/LuBaolu/intel-iommu/commits/iommu/vt-d/next
Please consider pulling this series into the iommu/vt-d branch.
Change log:
v2:
- Sashiko reported a critical issue in the previous PATCH 16/20. Remove
that patch from this series. It requires more investigation time and
will be submitted as a separate patch.
- Add comments to the commit message of PATCH 03/20.
v1: https://lore.kernel.org/linux-iommu/20260804023714.3080506-1-baolu.lu@linux.intel.com/
Best regards,
baolu
