[Qemu-devel] Any topics for today's MTTCG sync-up call?

["Alex Bennée" <alex.bennee@linaro.org>]

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,
