Subject: [PATCH 0/7] iommu/s390: support additional table regions
Date: Mon, 9 Dec 2024 14:25:42 -0500 [thread overview]
Message-ID: <20241209192549.107226-1-mjrosato@linux.ibm.com> (raw)
The series extends the maximum table size allowed by s390-iommu by
increasing the number of table regions supported. It also adds logic to
construct the table use the minimum number of regions based upon aperture
calculation.
Matthew Rosato (7):
iommu/s390: add initial fields to track table size
s390/pci: set appropriate IOTA region type
iommu/s390: add basic routines for region 1st and 2nd tables
iommu/s390: support cleanup of additional table regions
iommu/s390: support iova_to_phys for additional table regions
iommu/s390: support map/unmap for additional table regions
iommu/s390: allow larger region tables
