Tom> What do you think of "Failure to request the MMIO address Tom> space of the MSI-X PBA"? Or what name do you suggest?
Unless I'm misunderstanding the code, nothing is failing, and it's not the PBA being mapped. You're ioremapping the the MSI-X vector table so that the msi core can write vector values, etc. So I would suggest using a name of "MSI-X vector table" in the call to request_mem_region. (Remember that this name will be displayed in /proc/iomem, and I don't think it makes sense to display "MSI-X iomap Failure" to the user when MSI-X is set up and working).
