Address From Ip Address Link: Job Aborted Failure In Uio Create
Also check dmesg for PCI resource allocation issues:
For those writing custom UIO code, always handle missing IP addresses gracefully – return a clear error message and fallback to PCI ID-based addressing where possible. This will save hours of debugging for future users of your system.
INTERFACE=$(ip -o link | grep "00:11:22:33:44:55" | awk -F': ' 'print $2') IP_ADDR=$(ip -4 addr show $INTERFACE | grep -oP '(?<=inet\s)\d+(\.\d+)3') Then pass $IP_ADDR and $INTERFACE to your application. In embedded systems, the UIO device may not have been created in /dev due to missing udev rules.
echo 'KERNEL=="uio*", SUBSYSTEM=="uio", MODE="0660", GROUP="plugdev"' > /etc/udev/rules.d/50-uio.rules udevadm control --reload-rules udevadm trigger If the error persists, trace the UIO kernel path:
#SBATCH --memlock=unlimited # In SLURM If you control the source code, look for uio_create_address . A typical implementation might look like:
lspci -vvs 02:00.0 | grep "Kernel driver" # Use actual PCI id If it shows a kernel driver (e.g., ixgbe ), unbind it and bind to UIO:
