Hi, It's been a while since the last sync-up call. Have we got any topics to discuss today?
Sergey and I (with a little Paolo) have spent some of last week delving into the locking hierarchy w.r.t to tb_lock vs mmap_lock to see if there is any simplification to be had. I'm not sure if this is a topic conducive to a phone call instead of the mailing list but if others want to discuss it we can add it as an agenda item. We also have a new member of the team. Pranith has joined as a GSoC student. He'll be looking at memory ordering with his first pass at the problem looking to solve the store-after-load issues which do show up on ARM-on-x86 (see my testcase). Alvise, is there any help you need with the LL/SC stuff? The MTTCG aware version has been taking some time so would it be worth sharing the issues you have hit with the group? Emilio, is there anything you want to add? I've been following the QHT stuff which is a really positive addition which my v3 base patches is based upon (making the hot-path non lock contended). Do you have anything in the works above that? Cheers, -- Alex Bennée
