Date: Thu, 27 Apr 2017 17:28:23 +0200 From: Joerg Roedel <joro@...tes.org> To: Sebastian Ott <sebott@...ux.vnet.ibm.com>, Gerald Schaefer <gerald.schaefer@...ibm.com> Cc: iommu@...ts.linux-foundation.org, linux-kernel@...r.kernel.org, Joerg Roedel <joro@...tes.org> Subject: [RFC PATCH 0/2] iommu/s390: Fix iommu-groups and add sysfs support Hey, here are two patches for the s390 PCI and IOMMU code. It is based on the assumption that every pci_dev that points to the same zpci_dev shares a single dma-table (and thus a single address space). If this assupmtion is true (as it looks to me from reading the code) then the iommu-group setup code in the s390 iommu driver needs to be updated. These patches do this and also add support for the iommu_device_register interface to the s390 iommu driver. Any comments and testing appreciated.
