Re: [PATCH V4 00/24] IOREQ feature (+ virtio-mmio) on Arm

Hi, thanks for giving this update.

Since you were the only person who took the time to send such an
update I feel I can spend some time on trying to help with any
obstacles you may face.  Hence this enquiry:

So, I'm replying to V4 here.  Did you resolve your issues ?
What are the major outstanding risks to this series and do you need
any help from the Xen Project (eg from me as Release Manager) ?

NB I have not been following this series in detail - I'm just looking
at your mail and your 00/ posting and so on.  So if there is some
blocker or risk I am probably unaware of it.

I notice that there's one libxl RFC patch in there.  Since that's in
my bailiwick I will try to review it soon.
