Subject: thoughts stac/clac and get user for vhost
Date: Tue, 25 Dec 2018 11:41:13 -0500 [thread overview]
Message-ID: <20181225113301-mutt-send-email-mst@kernel.org> (raw)
Hi!
I was just wondering: packed ring batches things naturally.
E.g.
user_access_begin
check descriptor valid
smp_rmb
copy descriptor
user_access_end
So packed layout should show the gain with this approach.
That could be motivation enough to finally enable vhost packed ring
support.
Thoughts?
