Subject: [Qemu-devel] [PATCH v4 0/6] Rework vhost memory region updates
Date: Wed, 13 Dec 2017 18:08:01 +0000 [thread overview]
Message-ID: <20171213180807.7066-1-dgilbert@redhat.com> (raw)
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
Hi,
This patch set reworks the way the vhost code handles changes in
physical address space layout that came from a discussion with Igor.
Its intention is to simplify a lot of the update code,
and to make it easier for the postcopy+shared code to
do the hugepage alignments that are needed.
Instead of inserting/removing each section during the add/del
callbacks of the listener, we start afresh and build a list
from the add and nop callbacks, then at the end compare the list
we've built with the exisiting list.
v4
Rework based on comments from Paolo; now using add/nop rather
than doing another flatview walk.
Dave
