Probably although I hadn't looked specifically at doing so. Mapping the data via an unused pci bar is pretty trivial and seemed minimally intrusive to the existing driver.We'll run out of bars if we expend them like that.BAR1 is used for MSI-X already (if MSI-X is enabled), you can just add your data there. I would report the offset within the BAR somewhere in io space or in configuration space, so that we can relocate tables later if we like without changing guests.
I'd really like to avoid such entanglements. -- error compiling committee.c: too many arguments to function
