This certainly fixes the problem I originally reported: all the basic BARs for devices with SR-IOV enabled are mapped. When testing this, I noticed that a BAR which we fail to allocate space for may be left configured with an address range that overlaps that of other BARs. However, that does not appear to be a regression. Ben. -- Ben Hutchings, Senior Software Engineer, Solarflare Not speaking for my employer; that's the marketing department's job.
