There was a problem hiding this comment.
The LOG.error message is not exactly correct because the binding "will" fail. How about "Binding to vfio-pci will fail because IOMMU is disabled."
Does the Log.error call and the raise SystemExit result in two messages being printed? We only need error message and a non-zero exit.

Can we improve the commit message to something like the following? opae.io: Fix error handling when binding the vfio-pci driver fails The 'opae.io init' command can fail to bind the vfio-pci driver when the IOMMU is disabled, leaving the system seemingly unable to bind another driver. The fix is to check if the IOMMU is enabled before even attempting to bind the vfio-pci driver. |
