This project now in unusable-at-all state. There is no optimization at all and you need apt to 10 Mbps connection between spice client and server to see the smooth enough image. All the frames, generated by weston, even on mouse move are sent to the client side. So, to use it, you firstly need to upgrade it to new weston API and secondly perform much RnD work on optimization. I am pleased that you want to continue this project, I was very interested when I worked on it but I had to stop when I got very busy working in a company. I don't want to give up the project but my ability to contribute now is very limited. To sum up, to make it working you need many time/material resources. Maybe one time I will continue it, maybe sooner if there will be the good reason. But now I'm the technical leader in the startup and working hard. Right now I'm sitting in 4YFN (World Mobile Congress in Barcelona), talking to investors and watching our demo stand. Thank you again and see my answers in the quote, but I'm afraid they are useless for you, because I forgot many things about project and have no much time to remeber. <div class="moz-cite-prefix">On 02/22/2016 05:55 PM, Fabio Fantoni wrote: </div> <blockquote cite="mid:56CB3D9E.2020703@tiscali.it" type="cite"> <meta content="text/html; charset=iso-8859-15" http-equiv="Content-Type"> <div class="moz-cite-prefix">Il 05/10/2015 20:08, Yury Shvedov ha scritto: </div> <blockquote cite="mid:5612BCB8.6080607@lvk.cs.msu.su" type="cite"> <meta content="text/html; charset=iso-8859-15" http-equiv="Content-Type"> 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. </blockquote> 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: <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://github.com/Fantu/compositor-spice/commits/test">https://github.com/Fantu/compositor-spice/commits/test</a> 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? </blockquote> Unfortunately I can't fully understand your question, but if you asking how to make weston to listen for the spice clients, I can't give you complete answer. As I remenber you have to select spice renderer in configuration and it starts the server automatically. <blockquote cite="mid:56CB3D9E.2020703@tiscali.it" type="cite"> 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? </blockquote> I think yes, but not now. All the stuff was hardcoded. <blockquote cite="mid:56CB3D9E.2020703@tiscali.it" type="cite"> 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? </blockquote> I'm sure that rdp renderer is in much better state now then this one. <blockquote cite="mid:56CB3D9E.2020703@tiscali.it" type="cite"> Are spice the things used/needed more "stable" or continuous changes (and version prerequisite increments) will be needed? </blockquote> As I know spice is pretty old and stable protocol, so I don't think there are many changes needed in this way. <blockquote cite="mid:56CB3D9E.2020703@tiscali.it" type="cite"> Thanks for any reply and sorry for my bad english. <blockquote cite="mid:5612BCB8.6080607@lvk.cs.msu.su" type="cite"> Sorry for my english too! =) <pre class="moz-signature" cols="72">Kind regards Yury Shvedov</pre> <div class="moz-cite-prefix">On 10/04/2015 03:12 PM, Fabio Fantoni wrote: </div> <blockquote cite="mid:561117C4.3050705@tiscali.it" type="cite"> <meta http-equiv="content-type" content="text/html; charset=iso-8859-15"> 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: <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://github.com/ein-shved/compositor-spice/">https://github.com/ein-shved/compositor-spice/</a> Is about weston backend, with very basic features and without recent commits. Was posted also in this mailing list long time ago: <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/wayland-devel/2013-April/008902.html">http://lists.freedesktop.org/archives/wayland-devel/2013-April/008902.html</a> 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: <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://github.com/FreeRDP/FreeRDP/tree/master/client/Wayland">https://github.com/FreeRDP/FreeRDP/tree/master/client/Wayland</a> 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. </blockquote> </blockquote> </blockquote> <div class="moz-signature">-- Kind Regards, Yury Shvedov </div> </body> </html>
