Subject: [PATCH 0/4] iommu/amd: re-mapping fixes
Date: Fri, 13 Sep 2019 16:42:27 +0200 [thread overview]
Message-ID: <20190913144231.21382-1-adulea@amazon.de> (raw)
This patch series tries to address a few issues encountered when
replacing existing mappings:
.> pages leak in free_pagetable()
.> allow downgrading default page-sizes in alloc_pte()
.> tear-down all the replicated PTEs of a large mapping when downgrading
to smaller mappings
Andrei Dulea (4):
iommu/amd: Fix pages leak in free_pagetable()
iommu/amd: Fix downgrading default page-sizes in alloc_pte()
iommu/amd: Introduce first_pte_l7() helper
iommu/amd: Unmap all L7 PTEs when downgrading page-sizes
