Subject: s390 PCI dma ops
Date: Fri, 11 Sep 2020 09:27:34 +0200 [thread overview]
Message-ID: <20200911072734.GA23043@lst.de> (raw)
Hi S/390 PCI and IOMMU maintainers,
We've recently tried to convert all implementations of the IOMMU API to
use drivers/iommu/dma-iommu.c instead of their local IOMMU ops. I've
looked at S/390 and while some comments mention things about the iommu
API the implementation looks quite separate. Do arch/s390/pci/pci_dma.c
and drivers/iommu/s390-iommu.c driver the same hardware? If so would a
switch to drivers/iommu/dma-iommu.c be feasibel?
