Re: [Dri-devel] A few mach64 tests
First, thanks for your answers, both of you. And now, for some updates: Le Mon, 27 May 2002 20:10:23 -0400 (EDT) Leif Delgass [EMAIL PROTECTED] a écrit: Thanks for the report!

Nothing strange appears in the logs.Ctrl-C in the xterm closes the program (not cliking on the cross). The problem seems to be related with catching the mouse. I'll check with the new version tomorrow (I have the previous version for now). As for celestia, the yellow 'swapping' indicator appears just before celestia hangs. So it does seem it's trying to load new textures (of Earth). As for tuxracer, does it say anything about what it's looking for in the GLX visual that isn't supported? Too bad the problem isn't with version 0.6 (where we could look at the code) but the 1.1 commercial version. There's no debug (or help option), so there's only the lines: %%% tuxracer warning: Failed to set video mode Couldn't find matching GLX visual *** tuxracer error: Couldn't initialize video: Couldn't find matching GLX visual (Success) Also, I never get to see blue bars (ie AGP) with the PERFORMANCE_BOXES option: is it normal (agpgart module is loaded), ie local means already loaded in the card memory? -- Bernard Cafarelli aka Voyageur ICQ:66024647 Thanks for your answers, both of you.

[Dri-devel] A few mach64 tests
Well, here's my small contribution to the mach64 dev (sorry but I'm FAR away beyond you in programming, especially compared to people like Jose,Leif or Linus :)).

Re: [Dri-devel] A few mach64 tests
Thanks for the report! Concerning textures: the AGP texturing code is kind of a proof-of-concept and isn't very efficient yet. We need to work on reducing the amount of texture swapping that is happening. You can try AGP 2x, use Option AgpMode 2 in the Device section of XF86Config. Also, I have some code to increase the max texture size exported, but usually an app would refuse to run or use smaller textures if that's the problem. I should resurrect that bit of code. Something you can try to get a feel for what's happening with textures: export this environment var: LIBGL_PERFORMANCE_BOXES=1 You'll get some colored boxes and bars in the upper left corner of the GL window: From left to right: - A red box means glFinish was called to wait for rendering to complete. - A short bar showing approx. ratio of AGP/local textures used for a frame (AGP - blue, local - purple) - based on number of textures bound to the texture units, not size. - A yellow box means texture(s) were swapped during the frame - Then a split bar for texture uploads, AGP and local (same colors as above), based on size of the uploads. - On another row, a pink-ish bar for number of DMA buffers used. Note that many buffers are sent partially filled, so this is only an approximation of the size of data. I'm guessing that in most of the places where you see slowdowns, you'll see lots of texture swapping (yellow box) and/or the texture upload bars will be long (large texture uploads). Sound problems could be related to this and/or high CPU usage in wait loops?
