Hi, I am sending priority frame from my server with exclusive dependency flag set. However, I cannot see any priority frame in chrome://net-internals debug log. Also, I can not see any dependency stream update chrome side. Does chrome support/receives priority frame from server?

Hi,
I'm building the project with make in Linux Mint 14 cinnamon running with
nvidia drivers.
I have been able to find many of the dependencies. However, I'm a bit
stock.
In statecopytest , I get some undefined errors :

Hello folks, Just wanted to share that I've created a repository on GitHub (based on Jose Fonseca's import of the Chromium CVS repository) containing Chromium, and have added a CMake-based cross platform build system. [1] With this system, I've successfully built Chromium on Linux (64-bit RHEL 5 and Ubuntu Lucid) as well as Windows 7 with Visual Studio 2008. Cygwin or MSYS are no longer required on Windows: CMake generates a visual studio project if desired. it supports out-of-source builds (that do not generate/modify files inside the source tree) and installation of executables, libraries, headers, and mothership with make install for reasonable compatibility with earlier instructions. I've successfully run this build on the RHEL5 machine, while I've had issues on Ubuntu Lucid (matching those seen by [2]: "Render SPU: Display :0.0 doesn't have the necessary visual: RGB, Doublebuffer, Z") and Windows (segfault in crserver when locking a networking mutex after starting crappfaker). As I couldn't finish the build on these systems using the makefiles, I can't compare with the results from the earlier system. In any case, hopefully if there is any interest still in working with Chromium, this may be a useful contribution. Enjoy!

Hi, We're running a Chromium installation with 4 rendering machines, all on Windows 7. The demos and our own applications do start up fine, but we have the problem that rendering nodes freeze randomly after a while (on average around 5min). It is not always the same node and it happens on all the machines. If a node freezes we get the following warning in each frame: Problems at: wglSwapBuffers failed: return value of 0! So it seems that once there is a problem with wglSwapBuffers, it stays bad. The call that causes this warning is in renderspu_wgl.c: return_value = render_spu.ws.wglSwapBuffers( w->visual->device_context ); We tried a couple of different things in attempt to fix it, like using SwapBuffers() directly, but so far nothing helped. Also we tried to get more information about the error using GetLastError(). No help there either, it returns "The operation completed successfully." in both cases. Has anyone had this issue before?

Hello All, I am trying to understand what it would take to remote OpenGL calls from an android guest running inside VirtualBox to the host. From what I have seen, VirtualBox uses Chromium for 3d acceleration. However, the guest tools for Linux will not work as is on Android because of missing the X windows subsystem etc. If I wanted to remote android opengl calls to the host (running on Windows) I think I will need to patch opengl and egl calls in android and have them remoted to virtualbox. Has anyone worked on something like this before? Is there anything I should watch out for? I have no prior experience with 3d graphics so I might be wildly off here. Please bear with me :-) Thanks Suman |

Hi, Since it took me ages to find the solution to this problem, I thought I'd post it here to hopefully prevent others with the same problem from wasting time. Strictly speaking it's a Windows Server/cygwin problem, but that was less than obvious to me, trying to build chrome for the first time, and I wish the solution had been posted on this list (or any other chromium-related site for that matter). System: Windows Server 2008 Standard SP2, 32bit Problem: The following error occurred when building chrome: [main] bash 8980 _cygtls::handle_exceptions: Exception: STATUS_ACCESS_VIOLATION [main] bash 8980 open_stackdumpfile: Dumping stack trace to bash.exe.stackdump Project : error PRJ0002 : Error result 35584 returned from 'C:\Windows\SysWow64\cmd.exe'. Also, execution of chrome\src\third_party\cygwin\bin\bash.exe produced the following error message: 29 [main] bash 16312 _cygtls::handle_exceptions: Exception: STATUS_ACCESS_VIOLATION 5736 [main] bash 16312 open_stackdumpfile: Dumping stack trace to bash.exe.stackdump 29 [main] bash 16312 _cygtls::handle_exceptions: Exception: STATUS_ACCESS_VIOLATION 5736 [main] bash 16312 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack) Cause: If Terminal Services is installed and Data Execution Prevention (DEP) is turned on for all programs, execution of some cygwin applications, including bash.exe, fails. See the post http://cygwin.com/ml/cygwin/2008-10/msg00429.html and other posts in the same thread. Solution: Switch the DEP setting to "Turn on DEP for essential Windows programs and services only". To learn how, see: http://support.microsoft.com/kb/875352#5 See the post http://cygwin.com/ml/cygwin/2008-10/msg00459.html Hope this is helpful to someone. Cecilia |

Hello. I'm trying to get results of peformance tests for Chromium project. I use "master.chromium" as a master and "chrome-linux-perf" slave. I use Fedora 12 (32 bit) OS and I successfully build chromium and chromium.r61483.tgz archive as a base code. Its updated by gclient to the recent code successfully.

I am working on a parallel rendering project based on chromium. Our goal is to build a real time and multi-project system which can work well on various projected background. Briefly speaking, we load the source image and transmit it from one client where the app faker runs and process the image on several servers. Now we have implemented several algorithms within the SPU. However, to improve the performance, we have tried many ways and finally we transplant the algorithm from CPU to GPU and the result is promising. Actually, we can get more than 50 fps on a single PC with Geforce 8800 now. However, when we start to combine PCs using the local network, the fps drop down dramatically. It fell to nearly 24 fps when combine only two servers and one client. I'm sure it's due to the network performance and I tend to reconstruct the relative module of chromium. I found that the tilesort spu synchronizely swaps the buffer and every times not until all the servers have returned the application will be blocked. I wanna make the network image transfering and the image processing asynchronizely. Nevertheless, this is still a tough work for me. The only thing I know is that I can make a change upon the tilesort spu but I'm still not sure. Could anyone provide me some advice or if you have already make any contribution to this issue, would you mind sharing some resource with me. Thanks a lot. Michael |

I posted on the Chromium-users list but in retrospect I think this would be the better list. I'm trying to work on a project using Windows 7 and I'm having difficulty getting an app running. crserver reports "Connection refused." Using the same project code I have no trouble running on XP. I've done th obvious things, like turn on the firewall, but am getting nowhere. Any help would be greatly appreciated. I have ported the Chromium build to VS 2008 so that the project will build and run (on XP, see above) without cygwin, in case anyone is interested. It builds much, much faster under VS and the debugging/profiling tools are a cinch to use. -- Steve Kelley 106 Oklahoma Ave. Oak Ridge, TN 37830 865 482 7131 |

Hey all, the website, news groups and mailing lists seem very quiet. So i was wondering what the development status of chromium is. Is there still development going on or is the project put on ice? - Erwin |

Ive been working on figuring out how chromium is structured in order to implement OpenGL 2.1 functionality (initially starting with pBuffers) but Im having some trouble understanding how it all fits together. End of the day, where are openGL functions implemented? What Ive been doing so far is taking the 1.5 spec and looking up where I find the use of one extension in particular (ARB_vertex_buffer_object) in chromium 1.9, but Id much appreciate it if someone could lend me a hand and explain how chromium is setup and structured. Many thanks. -Andres -------------------------------------------- Andrés Molina Ing. De Sistemas y Computación Universidad de Los Andes Grupo Imagine |

I am running six crservers and a crappfaker on a single multi-core machine under WinXP. From time to time, the rendering windows hang. The longest run I've had is about 45 minutes. The typical time up is about 10 minutes with variation among the four different applications that I run. I read through the Chromimum dev archives and located a series of 2006 posts by Michael Durig where he includes a patch for non-blocking sockets instead of blocking. Here's the archive. http://sourceforge.net/mailarchive/forum.php?thread_name=45360EC9.4040108%40bfh.ch&forum_name=chromium-dev This patch (with some slight modifications and #ifdef bracketing) seems to do the trick at least for XP. I have now been running an app through Chromium for 18+ hours with no hangs yet. Couple quick questions: (1) Does anyone have thoughts or words of warning as to whether a non-blocking approach will cause other problems? (2) Anyone else seeing the hang behavior on WinXP?

Hello all, After working on a high resolution tiled display using Chromium and DMX, I have come across several issues (documented in the users mailing list archives) which lead me to believe I require OpenGL 2.x support. As part of my graduation project, I have decided to take on the task of implementing the necessary extensions over the course of the next few months. As far as I know, there is still no OpenGL 2.0 support to date, with little work done on it so far. Ive started going over the documentation as well as mailing list archives for pertinent information, but I would greatly appreciate any suggestions or pointers on the matter. Many thanks, -Andres -------------------------------------------- Andrés Molina Systems and Computer Engineering Universidad de Los Andes IMAGINE Group |

Chromium Dev-- Why does the CRServer have configuration parameters for 'view_matrix' and 'projection_matrix'? Alternatively, why not have two SPUs? One SPU premultiplies the view matrix, and a second one forces replacement of the projection matrix? Then attacth these SPUs to the CRServer of interest. Thanks in advance, --Dave -- David L.

Chromium folks--
I've modified renderspu_wgl.c to allow support for the 'borderless' option
in the Render SPU.
I've added the following code:
Changed line 384 from:
>> window_style = ( render_spu.fullscreen ? WS_POPUP : WS_CAPTION ); to:
>> window_style = ( render_spu.fullscreen || render_spu.borderless ?
WS_POPUP : WS_CAPTION );
and added the following code at line 428 or there abouts:
>> else if( render_spu.borderless )
>> {
>> window_style &= ~WS_OVERLAPPEDWINDOW;
>> window->x = render_spu.defaultX;
>> window->y = render_spu.defaultY;
>> window_plus_caption_width = window->width;
>> window_plus_caption_height = window->height;
>> crDebug( "Render SPU: Window borderless enabled.");
>> }
It seems to work with my system.
--Dave

I am over writing the projection matrix as the following python code
(snippet) below illustrates.
My motivation is that I want to have some more control over the projection
matrix for a tiled display. Currently, with the first code, the projection
matrix seems to be set and rigid, despite what happens to the projection
matrix in the application. However, I need to configure the projection
matrix specific to my wall display, but I also need some flexibility for it
to adjust on the fly via the application.
===begin snippet
renderspu = SPU( 'render' )
node = CRNetworkNode( "server%d" % id, "dynamic" )
node.Conf('optimize_bucket', 0)
node.AddTile( 0, 0, view.col, view.row )
p = CRMatrix()
p.Frustum( x_left, x_right, y_bottom, y_top, z_near, z_far )
node.Conf('projection_matrix', p.ToList())
node.AddSPU( renderspu )
cr.AddNode( node )
=== end snippet
My question is what if I created a "viewspu" that did the samething.
Basically, this new spu would intercept OpenGL calls that modified the
projection matrix (i.e. glOrtho, glFrustum, glScale, glRotate, etc.) and
force the projection matrix to remain as the one specified. The new python
code would look something like the following:
===begin snippet
viewspu = SPU('view')
renderspu = SPU( 'render' )
node = CRNetworkNode( "server%d" % id, "dynamic" )
node.Conf('optimize_bucket', 0)
node.AddTile( 0, 0, view.col, view.row )
p = CRMatrix()
p.Frustum( x_left, x_right, y_bottom, y_top, z_near, z_far )
viewspu.Conf('projection_matrix', p.ToList())
node.AddSPU( viewspu)
node.AddSPU( renderspu )
cr.AddNode( node )
=== end snippet

Hi all, I have an application which is using one single VBO for several objects. Its rendering loop looks like: (don't have the source of the app, got that from the print SPU) BindBufferARB( GL_ARRAY_BUFFER, 1 ) BindBufferARB( GL_ELEMENT_ARRAY_BUFFER, 2 ) VertexPointer( 3, GL_FLOAT, 32, 00000000 ) DrawElements... ... VertexPointer( 3, GL_FLOAT, 32, 00000FA0 ) DrawElements... ... VertexPointer( 3, GL_FLOAT, 32, 000113C0 ) DrawElements... but on th crserver, the print SPU gives something like: BindBufferARB( GL_ARRAY_BUFFER, 1 ) BindBufferARB( GL_ELEMENT_ARRAY_BUFFER, 2 ) VertexPointer( 3, GL_FLOAT, 32, 00000000 ) DrawElements... ... DrawElements... ... DrawElements... And the visual result is wrong. I looked a bit in chromium sources, and it came down to the crStateClientDiff function in state_client.c. The two CRClientState pointers "to" and "from" where the same, so the tests on change of size, type etc never passed. I just commented these tests and now the app works nicely, but maybe it breaks something else somewhere! Regards, Thomas |
