Description of problem: In working through a recent UIO BZ in 8.4/8.5, we needed to update ownership of UIO modules for RHEL8. Part of this was identifying which UIO kmods are actively needed. We know that we need CONFIG_UIO #Dependency for below configs CONFIG_UIO_PCI_GENERIC # (Used by DPDK over UIO) # This one is to support PCI bus but not # recommended. Drop-in replacement is vfio with # enable_unsafe_noiommu_mode=1 CONFIG_UIO_HV_GENERIC #This one is to support Hyper-V vmbus We could not identify users of the other CONFIG_UIO options; we should disable those in RHEL9. (They can be re-enabled on demand as needed later.)
