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: Oleksandr writes ("Re: [ANNOUNCE] Xen 4.15 release schedule and feature tracking"): > I work on virtio-mmio on Arm which involves x86's IOREQ/DM features. > Currently I am working on making the said features common, implementing > missing bits, code cleanup an hardening, etc. > I don't think the virtio-mmio is a 4.15 material, but it would be great > have at least "common" IOREQ/DM in 4.15. .. > > P: your current estimate of the probability it making 4.15, as a %age > > Difficult to say, it depends ... > RFC was posted Aug 3, 2020, The last posted version is V3.

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. Regards, Ian.
