Re: [Spice-devel] Spice arm port 2D rendering/requirements
Hi, We have been testing a number of thin clients lately, but I have to say that we haven't met one which did not have an X driver :) These include everything from HP thinclients to raspberry pis, trimslice etc. I think pixman does a pretty good job basic draw operations, but for video playback it could make sense to codec pass-through ( http://spice-space.org/page/Features/CodecPassthrough) to let the graphics driver decode it, instead of the overhead of encoding then decoding MJPEG. /Attila On Sat, Nov 10, 2012 at 9:39 AM, Alon Levy al...@redhat.com wrote: Hello, I have come to know that GNU/Linux Arm ports for various arm platforms out there usually dont have a working X server.

Meanwhile I would also try to disable off-screen surfaces, as was also mentioned in a previous reply, Ah, yes, sorry; I knew 20 was imprecise. But (500 / 80) * 80 ms is still a good bit of delay. Increasing the ack window (and pipe size) by a factor of 10 makes the first apparent problem vanish. Disabling off screen surfaces has the same user visible effect. Note, though, that I have the luxury of focusing on a long term agenda, so I'd rather pursue the 'best' solution (at least for now). What OS your client has? When spice-server identifies WAN, it automatically turn on Nagle's for the display channel (turns off TCP_NODELAY), which should aggregate small tcp messages. However, it has bad interaction with the delayed acks on the client side (especially in Windows clients, where the default delayed ack timeout is 200ms iirc), and overall it can lead to bigger latency between operations. We are planning to get read of this, and aggregate the messages on the application layer instead. I'm currently testing with Debian testing, although our eventual deployment platform will be a heavily modified RHEL 6 system. The pointer to TCP_NODELAY is also a good one; I'll play with that and see what effect it has. Just to clarify, we currently don't condense messages in spice-server, though it is another item in our TODO. Ah, okay, that's helpful (although there is some very limited pruning in red_worker.c, no?) Is that todo on anyone’s immediate radar? I'm certainly not qualified, but it seems like that could have an major impact on what we're trying to achieve (regular Office applications hosted on a pure Linux server across a WAN).

Re: [Spice-devel] Video buffering
Hi John, Did you check the guest cpu usage while playing back youtube? We have noticed that the bad video playback performance with flash was due to it using up all of the guest CPU, and of course it does not improve a lot by giving the VM more cores either... (ok this was on a 12 core AMD, where the cpu speed isn't as high per core as for other cpus) Switching to HTML5 playback on youtube gave about the same video performance as playing it with VLC, and we could play back 720p over a 15mbit DSL line with an acceptable overall performance.

Are there any plans to build some sort of buffering into SPICE when it detects a video stream? I'm sure many are thinking likewise but we are looking at video as not just a technology shift but a huge long term cultural shift almost as large as the printing press so we see any VDI solution which does not address video despite the huge technical hurdles as inadequate. We have already been told by some schools that they could not use our X2Go VDI model because of their need for video. Likewise, adoption has been delayed by some large PR / Communications companies because of a lack of video support. As we look at consumerization of VDI for potential service to lower income users, video is a potential show stopper. Enough of teaching Grandma to suck eggs but this is why we are so enthusiastic about SPICE - at least it has a fighting chance with video.

Also, gtk 3 has backends - did anyone do a backend for android? Since going forward we plan to ditch the spicec client, that would be really preffered. Now that I see what you have planned it sounds good, but better to use spice-gtk. of course that's not to say we won't love to see this working anyway :) spicec is entangled in the hierarchical system in C++! So my plan is this: first split the spicec into two parts,data and UI,transform the data part into libspicec.so;then rewrite the UI part in JAVA. Besides, I should also tinker some problems caused by the Crippled NDK C++ support and the Lamed bionic c lib in android . And now the first step is roughly done,hence the change of the spicec structure: From |--playback thread |--cursor thread spicec:spicec process（application process）--main thread-|--*record thread * |--inputs thread |--display thread To: === |--libspicec.so:application thread--main thread--| | | | |--display thread--| | | |---|--cursor thread---|--| | ||--inputs thread---| spicec:spicec process---| ||--playback thread-| | | | | | | -| | | | | |--spicec:platform thread--| The hierarchical relationship has been unleashed with one thread(record channel) deleted and two new threads (app and platform) created. The first as the data thread,the other as the work thread which is driven by the signals from the first thread as well as its sub threads and requested to do the UI-related work: platform thread：blocked and waiting:--job request---| | | | ^ | | | | | |--|--| | | | | platform thread over--if(job==die)--| send req. blocked and waiting | ^ | | | | | ^ | | | _|_ | | | | app/plbk/cusor thd |---job donedojob()--else--| | |-go on-| __ || |---feed back--| So the next work is to expose the native JNI interface in platform thread to the UI written in Android SDK. I try to use the UI frame of AndroidVNCViewer in code.google.com/p/*android*-*vnc*-viewer/,then the work of platform thread will be replaced by UI but the msg communication to libspicec will be remained. That's the easiest way I can envisage except rewriting all parts in spicec from scratch. It's tough too, for I have poor experiance in Java... Anyway, is there any other guy working on this? Is my way feasible??Any Ideas or help is appreciated. See above for ideas, don't read them as a criticism, I

Write me if you are interested and I'll furnish more details. Please include a self-introduction in your email with your skills and experience. Just FYI, spice has been ported to N900 and to PC-Z1, both arm based platforms. (different variants). The patches are not committed but I would gladly provide them.

I guess you still need X11 to run it, and since (at least the Xomap in the N810) does not do MIT-SHM, I'm guessing it would be rather slow currently. on N900 it was usable, under X11 like you say. I don't know the difference between the machines relating to graphics driver, but I didn't use any opengl. also, same resolution I think (800x480 or something like that). I don't have a n810 to test on. The patch I was referring to is very simple, basically: 1. one line to configure.ac to let cpu check pass 2. empty implementation for atomic ops - haven't given this much testing, but it seemed to work. of course the right way would be to actually have an arm implmenetation, but I don't know enough arm assembler to write one, if you find someone to do this they could do better here :) Attila Did you have any issues with the guest resolution? (since the device display has a non standard res?) Attila ___ Spice-devel mailing list Spice-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/spice-devel

Can you put up patches somewhere? I guess this still uses X11 on osx, right? Yea, it is using X11. Porting to Cocoa would be a rather bigger job. I'll try to clean it up a bit and upload a patch somewhere... So now I'm only facing a few minor issues/things I've noticed: 1. Video playback seem to stop after a few seconds, but if the window is moved around or scrolled the video playback resumes again for a few seconds. I've tried it with VLC, windows media player and flash video players (youtube). Also, sometimes only the center square gets updated but not the rest. It is not very consistent as sometimes the video plays back fine.. Weird. No idea... 2. Bandwidth usage seemed to have increased, with the v0.4 client ive been seeing 1-2MB/s for full screen HD video playback, while with the current one I've been seeing peeks of 8-9MB/s on a 100mbit network Yeah, there has been some changes with e.g. the offscreen surfaces, etc that probably needs tweaking to get back to previous levels. Once we're feature frozen and have all this down we need to sit down and measure and tweak things. 3. We didn't receive (as far as I'm aware) the linux firefox plugin for the client with our RH beta package, and Im not sure where to find it? I've ended up creating a launcher script, associated that with spice:// protocol in firefox and modified the javascript on the management machine to redirect to a spice:// address in case the plugin wasn't found. Not sure if this is the best way of doing it? spice-xpi is not on freedesktop.org atm. I guess we should maybe put it up, although i don't know if its generally useful for non-rhel customers. I had a quick glance at the spice-xpi, but it seems way too complicated for a simple function of launching the spice client with the correct arguments...

One thing I noticed though was that the epoll implementation watched the fds for both read and write (add_to_poll()), but since it is edge triggered, it only fires once per change, but my select() implementation is level triggered, which meant it would never block and use up 100% CPU (for example monitoring a File fd, it always triggers). After playing a bit around with it, i decided to drop watching write for fds all together, and the client seem to work fine. Is there a need to check it or am I safe with monitoring only reads? It isn't save. When you got -EAGAIN from a write() or send() syscall because the output pipe is full you have to watch for the socket becoming writable so you can flush out the bits you havn't sent yet. As far I know there is no bulk data going from client to server, so if you are working on a fast LAN it is quite possible that you never hit the output pipe full case and the client works fine for you. Now on to the audio, I have been implementing audio using CoreAudio Framework for OS X (another idea could be OpenAL which is also cross-platform?), which pulls in a lot of extra headers, including MacTypes.h which unfortunately defines a Rect and Point struct which causes issues with the definitions inside common/draw.h. I can hack around it, but its not very nice, or I could rename the ones in spice, but that would break any compatibility with my patches to the current upstream code. What code base you are working on? In the unstable tree the structs have been renamed to SpiceRect and SpicePoint exactly to avoid name clashes like this. Also the headers have been splitted away into a spice-protocol package. A few days ago Alex landed the marshaller bits in the unstable tree and the spice client can handle both 0.4 and unstable spice protocols now. So you can jump to the unstable code base even if you need the client play nicely with 0.4 spice servers. This will also make it easier to merge your patches upstream. HTH, Gerd Hi Gerd, Thanks for the fast reply! Sounds good! Yes, right now I've been working on version 0.4, but since the unstable tree is now backwards compatible, I will move on to that.

[Spice-devel] spice BSD/OSX client
Hi guys, I have spent the last day or two doing some porting so that spicec would use kqueue on bsd instead of epoll. I have disabled audio for now, but once the current version works as it should, I will do a port to CoreAudio aswell. I now have a working version, however I had to disable the shm stuff in order to get it to work since I have been getting the following error: 1275161751 ERROR spice : x_error_handler: x error on display :0.0 error (code 10) BadAccess (attempt to access private resource denied) major 139 minor 1 request 139 Since the major code (139) is outside the 125? which is the standard codes in X, I guessed that 139 is an Xorg extension, $ xdpyinfo -display :0 -queryExtensions |grep 139 MIT-SHM (opcode: 139, base event: 76, base error: 145) So my wild guess is that it tries to write outside the available buffer?
