Re: [Qemu-devel] cocoa.m using openGL
Hi Peter, That is really great! To send your work: 1) download the cvs repository, see: http://savannah.nongnu.org/cvs/?group=qemu 2) send your diff: # cd /path/to/qemu # cvs diff -u cocoa.m > cocoapatch.diff.txt If you think your patch is clean enough, send it to Fabrice (and the list) so that it can be merged in qemu's repository. It seems that cocoa.m is under heavy work, which is good :) Pierre. Le 22 mai 05 à 15:00, Peter Stewart a écrit : Hello to all, esp. Pierre d'Herbemont, I have changed cocoa.m (0.7.0) to use openGL with very fast texturing. I removed the use of QuickDraw. The DisplayState data is now DMA'd to the graphics card instead of copied by the CPU. This uses apple's texture range extensions. The change means that the transfer of "display memory" incurs no CPU overhead. I also put in a bit more mouse stuff, and made some other fixes. I can't work out how to get the Window to get focus once it loses it, which is really a pain. I Shark'd it to make sure there wasn't any overhead from the texturing. I tested with Knoppix and FreeDOS. I am not sure if this is of interest to people, I just had a lazy weekend. I would like to give the code to the qemu project, but don't really know how to. thanks, peter. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
Re: [Qemu-devel] cocoa.m using openGL
Hello Peter and Pierre I have woven the patch into my patch and run some basic but in other times often used benchmarks with doom: i unpacked freedos and installed doom from http://www.kberg.ch/cocoaqemu/files/freedosdoom.img.zip then i started doom with doom -timedemo demo3 (reboot between the runs) realticks with QD 2542 2544 2543 2543 2545 Average: 2543.4 => 29.3662 fps realticks with openGL 2476 2466 2447 2451 2454 Average: 2458.8 => 30.3865 fps To get fps from these Number you have to 35*2134/realticks => openGL is 3.5% faster on my system plus - it solves some issues i had with hiding/showing the toolbar (damaging the qd_view) - it could accelerate the generation of livethumbnails i am using Testbuild and diff are on http://www.kberg.ch/cocoaqemu At this point I'm asking, whether my patch should/can be included into the CVS, what changes I should make, or how to continue...

Especially, if somebody writes a openGL driver/wrapper for the GuestOS. I'm working on cocoa.m for some time now, especially UI Things. But I did not get around submitting the stuff yet. You find my diff on www.kberg.ch/cocoaqemu. It consists of a lot of changes (including mouse and keyboard support :) ) Last update: this weekend.

Re: [Qemu-devel] cocoa.m using openGL
Peter, You can use the "diff" command (I think it's available on OS X) to create patches, and then you can post those patches here. Please add comments wherever possible to indicate what you done (something small and simple). BTW: have you tried to perform any benchmarking to see if there's any speed gain from your work compared to the standard QEMU?

[Qemu-devel] cocoa.m using openGL
Hello to all, esp. Pierre d'Herbemont, I have changed cocoa.m (0.7.0) to use openGL with very fast texturing. I removed the use of QuickDraw. The DisplayState data is now DMA'd to the graphics card instead of copied by the CPU. This uses apple's texture range extensions. The change means that the transfer of "display memory" incurs no CPU overhead. I also put in a bit more mouse stuff, and made some other fixes. I can't work out how to get the Window to get focus once it loses it, which is really a pain. I Shark'd it to make sure there wasn't any overhead from the texturing. I tested with Knoppix and FreeDOS. I am not sure if this is of interest to people, I just had a lazy weekend. I would like to give the code to the qemu project, but don't really know how to. thanks, peter. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
