Posted by Lu Baolu 3 years, 9 months ago

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.

Please help review and suggest.

Best regards,
baolu

Lu Baolu (6):
  iommu/vt-d: Remove unused domain_get_iommu()
  iommu/vt-d: Use IDA interface to manage iommu sequence id
  iommu/vt-d: Refactor iommu information of each domain
  iommu/vt-d: Add VTD_FLAG_IOMMU_PROBED flag
  iommu/vt-d: Remove global g_iommus array
  iommu/vt-d: Make DMAR_UNITS_SUPPORTED default 1024
