I was wondering if the PCI passthrough support was added in a later version. It would be great to know the latest status of the PCI passthrough support for the Xen PVM mode. Please let me know if you have any updates on this. Thanks, Mehrab ^ permalink raw reply [flat|nested] 5+ messages in thread

Please let me know if you have any updates on this. I think you meant PVH mode in the sentence above instead of PVM? Sadly status is still the same, there's no support for PVH and PCI passthrough on domUs yet. Arm folks are working on using vPCI for domUs, which could easily be picked up by x86 once ready. There's also the option to import xenpt [0] from Paul Durrant and use it with PVH, but it will likely require some work. Roger.

Do you have any timeline in mind on when support for x86 will be available? A rough estimate would help me with planning something.

Do you have any timeline in mind on when support for x86 will be available? A rough estimate would help me with planning something. I'm adding the relevant people working on this, Oleksandr for the vPCI Arm work and Paul for xenpt. The xenpt stuff shouldn't be complicated (Paul can correct me), as it would mostly involve importing xenpt into the xen.git repository and then wiring it up for the toolstack to use it, at least to get an initial version working.

This is indeed WIP and the thing is being developed by many parties: ARM, EPAM, Xilinx... And unfortunately I cannot give you even a rough estimate when this is going to happen as there are so many topics to cover for ARM yet. Of course, we try to make the code fit x86 as well, so we share the code between the architectures...
