Say, keep it on Thursdays > (USA) (kinda short notice), bi-weekly, we can do: I've asked several people in Europe to help on parts of this series, and combined with China/Aus someone is going to end up left out. I know people are anxious about their projects. In the short term I will volunteer to send patches (ie bug fixes!) to Linus in the CC area Dan was responsible for. Please email me if something needs some attention and we can figure it out. To fully move forward we need to establish a new TSM maintainer team. In my past experience a consensus has emerged off list, I suggest we try that here as well. Several people should be recruited. I will also volunteer to help train and launch a new team. I can say that several people from NVIDIA are working on the ideas in this patch series. Ankit is setting up a team to focus on upstream patches for all of CC inside NVIDIA. I've asked Jiri Pirko to work on the PCI evidence uAPI based on his deep netlink experience, and Leon Romanovsky to work on the binding problem/adversarial/trust level driver core idea. They will share their approaches for solving these problems as seperate proposals. > Scenario A: > Seattle (PDT, UTC-7) 07:00 – 08:00 Day 1 > Atlantic Time (ADT, UTC-3) 11:00 – 12:00 Day 1 > Berlin (CEST, UTC+2) 16:00 – 17:00 Day 1 > India (IST, UTC+5:30) 19:30 – 20:30 Day 1 > China (CST, UTC+8) 22:00 – 23:00 Day 1 > Sydney (AEST, UTC+10) 00:00 – 01:00 Day 2 (I can do it once in 2 weeks) This is the only time Europe could reasonably participate in, obviously it is not OK for China and Aus. > Please, comment.

LPC is not that far away, I think we should have a goal of having a consensus for or at LPC Regards, Jason
