Agenda items?

Cota" , Paolo Bonzini Hi, It's been awhile since we synced-up with quite weeks and Easter out of the way are we good for a call today? Some items I can think would be worth covering: - State of MTTCG enabled LL/SC I think Alvise was looking at some run-loop changes for the MTTCG enabled part of his LL/SC patch set. I haven't heard anything for a while. - Linaro's current efforts Sergey is currently working with us in up-streaming MTTCG related patches. We've taken stuff from Paolo and Fred's trees and push several series to the list for review: - various TCG clean-ups - atomic jump patching - base enabling patches - Memory ordering work I put this up as a suggested project for GSoC and we had several applicants. We are currently awaiting Google's decision on slot allocations so hopefully we'll have an extra pair of hands on this chunk. - Emilio's work Emilio posted a series last year with some alternative approaches to solving some of the MTTCG problems. He's back and working on this again and has posted his qht series as a precursor to his next revision of the MTTCG tree. - TCG maintainers view It would be useful if we had a view from the TCG maintainers of how we are doing and if the approaches have a chance of getting merged. - Timescales Internally at Linaro we've been discussing potential timescales. We are currently aiming to have all major pieces of MTTCG posted on list and being iterated through reviews before this years KVM Forum. This will leave us KVM forum to resolve any remaining barriers to eventual up-streaming. Anything else worthy of discussion? If you need the number to call ping me off list. -- Alex Bennée
