DPDK – EAL Input/output error
Last week I'm trying to reproduce a bug happened in our customer environment, so we create a minimal example for this: https://github.com/glasnostic/nff_go_test
During this, I found an annoying problem and want to record it.
I got an error:
EAL: Error enabling interrupts for fd 10 (Input/output error)
After some research, I found a patch for this(it didn't be merged into DPDK since it's a VMWare problem).
If you try to bind NIC that using
e1000 you might have the same issue.
To solve this disables the checking by:
sed -i "s/pci_intx_mask_supported(dev)/pci_intx_mask_supported(dev)||1/g" \ $(DPDK_PROJECT)/kernel/linux/igb_uio/igb_uio.c
This would make
pci_intx_mask_supported check do not work anymore.
then recompile, after compiling done, reload the kernel module:
rmmod igb_uio insmod $(DPDK_PROJECT)/build/kmod/igb_uio
DPDK_PROJECT is the project root directory of DPDK, related to
Then this problem should be fixed.
