I'd like to either have this resolved, or at least understood it before we accept the series. If you drop your pci-testdev implementation (patch 11/12) into x86/vmexit.c, in order to replace the implementation there, does pci-testdev still work? I.e. have you checked if x86 works both with its current implementation and yours? > > Most interesting - writing to IO BAR on ARM does not seem working as > a written value does not read back.

I'm glad to see it coming together!
