Why does it exit? VFIO should build the virtual capability list from scratch (just like classic device assignment does), recreating the layout of the physical device (except for masked out caps). In that case, this conflict should become impossible, no? But if pci_*add*_capability should actually be used like this (I doubt this), some renaming would be required. "Add" sound like "append" to me, not "update". Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
