Hi, Fabio!
Thank you for your interest to this project! But unfortunately
this project now is in proof-of-concept state and usable only via
loopback network. And as you notice it did not evolve by me for
years. The problem is I changed my scientific theme by accident at
this point and could not continue it as I have wanted. But I feel
this project has big potential and space of improvement. It would
be great if you want and can to handle this project and I will
support you as I could.
Hi, I have only little free time and very low knowledge but
I'm looking if is possible rebase your project on latest weston
version and try it.
To make easier and faster see what are the add/changes of spice
compositor and rebase it I created a new branch with latest
upstream commit you used, all changes except the latest commit
in first commit added and a cherry-pick of the latest:
https://github.com/Fantu/compositor-spice/commits/test
I not saw an howto and from a very fast code look seem that "--enable-spice-compositor
--enable-monitor-renderer" add in configure is
needed and when start listen seems hardcoded on localhost:5912
@Yury Shvedov: Can you send me all
essential notes for use it if they exist?
For what you know rebase on latest weston version will require
many changes/fixes or should be working or easy to adapt?
(documented api/functions weston changelog for compositor or
other module)
Should be possible add other spice options, for example
compression, where listen (ecc...) to pass to spice-server and
make it easy possible use them with small patches for fast lan
tests or require bigger work?
I saw that rdp is already present by years but any time I looked
it seems always that newer freerdp version (in development was
needed), not good stable api probably?
Are spice the things used/needed more "stable" or continuous
changes (and version prerequisite increments) will be needed?
Thanks for any reply and sorry for my bad english.
Sorry for my english too! =)
Kind regards

Hi, trying to have better performance on low cost spice thin
client (for example rpi2) I saw too low performance,
remote-viewer at 100% cpu with only one core used, but also xorg
process with high cpu usage and all other things open unusable
(including a simple terminal).
I tried with wayland using weston (GDK_BACKEND=wayland
remote-viewer), spice performance is still too low
on "high usage" but all other things is fully usable.
I'm trying to improve spice performance with opengles (using vc4
drivers) and compiling cairo for using it but for now I had some
problems.
I tried to search other spice tests with wayland, I found this
old project:
https://github.com/ein-shved/compositor-spice/
Is about weston backend, with very basic features and without
recent commits.
Was posted also in this mailing list long time ago:
http://lists.freedesktop.org/archives/wayland-devel/2013-April/008902.html
Seems interesting a possibility of better performance (including
possible future acceleration with opengl and/or vulkan) and
integratation.
Someone still working on it?
I also see a specific wayland client on freerdp for example:
https://github.com/FreeRDP/FreeRDP/tree/master/client/Wayland
Doing something similar for spice client can be useful or other
importance changes are needed for significative performance
improve?
About qxl driver in linux domU's seems there are problems with
many desktop envinment (gnome, kde, unity ecc... I saw it
reasonable on lxde on my
tests), I saw qxl kms support and something in drm about qxl, it
can works for example for a fast test with weston drm backend
and I should try or addition thing is needed?
Sorry is these are stupid questions but I don't have knowledge
about.
Thanks for any reply and sorry for my bad english.
