Description marco.bore 2020-10-21 14:53:08 CEST

NIC: Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
OS: CentOS Linux release 8.2.2004 (Core)
Kernel: 4.18.0-193.19.1.el8_2.x86_64


The command:
python3 ./dpdk-devbind.py --bind uio_pci_generic 0000:82:00.0 
Error: bind failed for 0000:82:00.0 - Cannot bind to driver uio_pci_generic

dmesg log:
[ 2571.106721] genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 49
[ 2571.106795] uio_pci_generic: probe of 0000:82:00.0 failed with error -22


How can I fix that?

Rather than using uio, can you try using vfio-pci driver? It supports everything that uio-pci-generic does, but provides more security too.

Hi Bruce, thanks for your reply,
unfortunately I have the same issue with the vfio-pci driver

python3 ./dpdk-devbind.py --bind vfio-pci 0000:82:00.0 
Error: bind failed for 0000:82:00.0 - Cannot bind to driver vfio-pci

dmesg log:
[10597.223610] vfio-pci: probe of 0000:82:00.0 failed with error -22

Macro, while using vfio-pci, did you enable IOMMU?
