[Xen-devel] Support for VMEbus in Xen

Good day,Â

I apologize in advance should this be way off topic for this list. ÂI have tried the Xen users group and haven't got anywhere, realising this is somewhat more specialised than I initially thought.Â

I'd like to know if it is possible to expose VMEbus functionality on a Xen guest? ÂI have spent a lot of time digging around the Xen source code and online documentation (as well as Google) but cannot find any specific reference to this. ÂWhile VMEbus appears to be in the Linux kernel it does not seem that the driver is exposed though the PCI side leading me to believe it is not possible to use PCI pass-though. Â

If my analysis so far is correct, is it even possible to provide this kind of functionality and if so would you be able to give me an idea of effort estimates? ÂA very short and outdated thread I found indicated that it may be possible to use memory mapping to expose the VMEbus driver on PCI. ÂThis sounded like a reasonable and fairly clean solution but whether it worked or not wasn't clear.

I would think there are quite a few use cases for this although obviously it's quite specialised and may not have broad appeal. ÂAny feedback or pointers to further reference material would be greatly appreciated.Â
