Hmm, it's a problem indeed, device initialization fails in case an io bar is present even if the bar is not required to drive the device. Suggestions how to deal with this best? ovmf has it's own IncompatiblePciDevice Protocol implementation, so I could handle it there because only OvmfPkg/Microvm needs this. Or should the MdeModulePkg version be updated too? thanks, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
