BTW I strongly suggest that you don't use uio_pci_generic. Starting with kernel 4.4 vfio-pci even supports no-iommu mode for systems which lack IOMMU. uio_pci_generic is on the black list for a long time by the kernel community, MSI and MSI-X interrupt support was never added....
Also, uio_pci_generic actually just provides interrupt support for PCI devices, BARs are mapped trough sysfs by simply doing open(), mmap() on /sys/bus/pci/devices/......./resourceX so access to that file is also required inside container. > On 7 Oct 2019, at 18:52, Jon Loeliger via Lists.Fd.Io > <jdl=netgate....@lists.fd.io> wrote: > > On Mon, Oct 7, 2019 at 11:04 AM Benoit Ganne (bganne) <bga...@cisco.com > <mailto:bga...@cisco.com>> wrote: > > In each of the cases above where I said "still doesn't work", when the > > /dev/uio* is present, it is found.
