The problem is that something seems to be broken in the iommu/core branch. Regardless of whether I have my DMA API conversion on top or with the base iommu/core branch I can not use ConnectX-4 VFs.Have you already tried to bisect the issue in the iommu/core branch? The result might sched some light on the issue. Regards, Joerg
Hi Joerg, Working on it, somehow I must have messed up earlier. It now looks like it might in fact be caused by my DMA API conversion rebase and the "s390/pci: Use dma-iommu layer" commit. Maybe there is some interaction with Jason's patches that I haven't thought about. So sorry for any wrong blame. Thanks, Niklas
