[Qemu-devel] [PATCH qemu v3 00/13] memory: Reduce memory use |
Date: |
Mon, 18 Sep 2017 20:16:56 +1000 |
This was inspired by https://bugzilla.redhat.com/show_bug.cgi?id=1481593
Previous versions:
v1: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg01559.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg04069.html
This patchset tries to reduce amount of memory used by FlatViews
and tries share as many FVs between address spaces as possible.
Changelog:
v3:
* addressed comments from v2, mainly simplified the code
v2:
* total rework
This is based on sha1
4f2058ded4 Peter Maydell "Merge remote-tracking branch
'remotes/rth/tags/pull-tcg-20170917' into staging".
Please comment. Thanks.
