[PATCH 0/2] Don't insert DDT cache in Bare mode

Posted by Jay Chang 2 days, 12 hours ago

When IOMMU is in Bare mode, DDT (Device Directory Table) lookup is not
performed. This series fixes two issues:

1. Avoid inserting unnecessary DDT cache entries in Bare mode
2. Properly free Bare mode contexts to prevent memory leaks
