Here are the final opens I see: * I expect we'll just merge this whole thing through the Intel tree, even though patch #3 adds the properties, structures, and helpers to the DRM core, so we need to get an okay from airlied. Dave, do you have any concerns about this? * I know the ChromeOS guys have been reviewing this series independently on their end and putting together the userspace (open source) which will be using this. We should get someone to formally Ack this on their behalf; I think Rob Bradford has been working with them; adding him to the Cc list to see if he can provide the Ack. * I'm not sure if I ever saw a CI report for your final iteration. I may have just missed the email, or it may have never come out due to the temporary FDO downtime or the CI outage last week.

Emil had a good argument that if we make something atomic-only to start with, it's trivial to change in the future if we decide we actually want to make use of it with a non-atomic userspace; on the other hand, if we make it unrestricted on day one, that's a change we can't reverse down the line since it becomes part of the ABI. However nobody seemed to really care very strongly either way during the discussion on the color management series, so I'm just putting this here as a final warning in case anyone really wants to see it changed before merging.</pre> </blockquote> I don't mind switching to atomic only. </blockquote> Actually, talking with Rob, it might be a bit tricky for ChromeOS. Most of the userspace modifications have been reviewed with the assumption that we didn't need atomic. Switching the userspace as atomic aware might have unintended consequences. <blockquote cite="mid:56DEACAC.8080608@intel.com" type="cite"> <blockquote cite="mid:20160308024641.GB5450@intel.com" type="cite"> <pre wrap=""> Thanks!
