Subject: [PATCH v11 00/19] Initial support for multi-process Qemu
Date: Thu, 15 Oct 2020 14:04:53 -0400 [thread overview]
Message-ID: <cover.1602784930.git.jag.raman@oracle.com> (raw)
Hello,
This is the v11 of the patchset. Thank you very much for the
review of the v10 of the series. We are glad to hear the
patchset is getting in a better shape.
We made changes to the following patches in this series.
[PATCH v10 06/19] multi-process: define MPQemuMsg format and transmission functions
[PATCH v10 08/19] multi-process: Associate fd of a PCIDevice with its object
[PATCH v10 10/19] multi-process: introduce proxy object
To touch upon the history of this project, we posted the
Proof Of Concept patches before the BoF session in 2018.
Subsequently, we posted 9 versions on the qemu-devel mailist.
You can find them by following the links below ([1] - [9]).
Following people contributed to the design and
implementation of this project:
Jagannathan Raman <jag.raman@oracle.com>
Elena Ufimtseva <elena.ufimtseva@oracle.com>
John G Johnson <john.g.johnson@oracle.com>
Stefan Hajnoczi <stefanha@redhat.com>
Konrad Wilk <konrad.wilk@oracle.com>
Kanth Ghatraju <kanth.ghatraju@oracle.com>
We would like to thank QEMU community for your feedback in the
design and implementation of this project.
