Subject: [PATCH v2 0/6] iommu/vt-d: Reset DMAR_UNITS_SUPPORTED
Hi folks,
This is a follow-up series of changes proposed by this patch:
https://lore.kernel.org/linux-iommu/20220615183650.32075-1-steve.wahl@hpe.com/
It removes several static arrays of size DMAR_UNITS_SUPPORTED and sets
the DMAR_UNITS_SUPPORTED to 1024.
This series is also available on github:
https://github.com/LuBaolu/intel-iommu/commits/reset-DMAR_UNITS_SUPPORTED-v2
Please help review and suggest.
Best regards,
baolu
Change log:
v2:
- Set the right @max for ida_alloc_range() and return the right error
when ida_alloc_range() returns failure.
- Replace xa_store() with xa_cmpxchg().
- Set domain->nid to NUMA_NO_NODE when domain is detached from an
iommu.
- Avoid adding a new VTD_FLAG_IOMMU_PROBED flag. Remove the duplicate
check directly.
v1:
- https://lore.kernel.org/lkml/20220625125204.2199437-1-baolu.lu@linux.intel.com/
- Initial post.
