Hi,

Mmm, but doesn't libpciaccess allow to map the BAR?Then pci-arbiter
could create a read-only memory proxy of the mapping?

Yes, the arbiter exposes the BAR regions as files called "region0", "region1", etc. And they can be mapped through a proxy, that's already working. But this is about the "rom" files which expose the content of the expansion ROM for each device.
