| kees | anyone around to talk me through bleeding-edge intel? I've got stuff from the xorg-edgers PPA installed, but when I forced on UXA, 3d performance dropped by about 60%. | 03:45 |
|---|---|---|
| tjaalton | kees: still around? check the log if DRI is enabled | 07:09 |
| tjaalton | hmm, mfb has been disabled and xf1bpp purged from the server sources.. maybe time to let x-x-v-sunbw2 go :) | 07:41 |
| kees | tjaalton: yup, dri2 is enabled | 16:51 |
| tjaalton | kees: hum, ok. maybe it needs a newer mesa or something | 16:56 |
| tjaalton | there is a "2008-q4" branch available, dunno when it's going to be merged to master. maybe that could help | 16:57 |
| kees | tjaalton: yeah, I'm reading http://intellinuxgraphics.org/download.html at the moment | 17:03 |
| kees | tjaalton: sounds like the ppa libdri2 is a few days behind | 17:03 |
| tjaalton | kees: heh, could be | 17:08 |
| tormod | I think stuff that came in libdrm after c86d431f is mostly kernel-mode-setting stuff | 17:24 |
| tjaalton | kees: which app are you using for testing? | 17:25 |
| kees | tjaalton: I'm using tremulous | 17:25 |
| kees | tormod: any ideas what I should change/tweak? | 17:25 |
| kees | right now the only non-default thing I have set in xorg.conf is to use UXA | 17:25 |
| tormod | kees: I have very little hands-on on intel. sitting on one now over Christmas but haven't tested all the edgy stuff. | 17:26 |
| tormod | are there any complaints in the log? | 17:27 |
| kees | tormod: okay, cool. I'm happy to be a tester for you :) | 17:27 |
| kees | not that I've found | 17:27 |
| tormod | well I actually have -intel git master and libdrm from ppa installed, so I am almost on the edge :) | 17:28 |
| kees | tormod: though, it seems to load the i915 driver, not i965. | 17:28 |
| kees | tormod: where is the git master ppa? I saw stuff from about 9 days ago on xorg-edgers | 17:29 |
| tormod | kees: there's none. I can push it to xorg-edgers. | 17:29 |
| kees | cool, yeah | 17:29 |
| kees | (WW) intel(0): ESR is 0x00000001, instruction error | 17:31 |
| kees | (WW) intel(0): Existing errors found in hardware state. | 17:31 |
| kees | that's the only error I can find | 17:31 |
| crevette | kees, does tremulous works well for you performance-wise ? because for me is slow as hell somtimes, fps decreases to 3 | 17:44 |
| tormod | kees, it's building in the ppa now. | 17:47 |
| kees | crevette: with EXA, and all the fancy stuff turned down, I usually stay above 6fps | 17:47 |
| kees | tormod: cool | 17:47 |
| kees | crevette: normally it's around 15-30, with simple rooms at 90 | 17:47 |
| kees | crevette: with UXA, it's about 2fps | 17:47 |
| crevette | kees, for me I didn't touch anything in xorg so I believe I have no xorg.conf | 17:48 |
| crevette | so I wondered if I didn't miss something in my conf (not in a required group, ...) | 17:48 |
| kees | crevette: with normal (exa/dri) I just turn all the fancy stuff off in tremulous | 17:49 |
| crevette | kees, for 3D performance, I just need to be in video group, right ? | 17:49 |
| tormod | crevette: yes | 17:50 |
| crevette | okay | 17:50 |
| tormod | glxinfo should confirm it's ok | 17:50 |
| crevette | yeah, I use dri | 17:50 |
| tormod | oh I forgot, nothing builds in Jaunty now, because of a conflicting drm headers in linux-libc-dev ... | 17:52 |
| tjaalton | again? | 17:54 |
| tjaalton | I thought the kernel header should not be installed until libdrm is fixed | 17:55 |
| tormod | last time I added a Replaces: linux-libc-dev (<= 2.6.28-3.4) to libdrm, but now a new kernel is out with the same issue. | 17:56 |
| tjaalton | oh right, it was fixed with a Replaces in libdrm | 17:57 |
| tormod | I'll drop the versioning in the ppa. and there will be a new libdrm from master git for kees :) | 17:57 |
| tormod | last time I tried k-m-s in the ppa I discovered many people were using it :) I hope current libdrm is more backwards compatible. | 17:59 |
| tormod | kees, with updated libdrm and -intel, glxgears went up from 800 to 930, but enabling UXA gives 390 - because then I get DRI2 I guess. | 20:33 |
| kees | tormod: upstream told me that glxgear isn't a good measure of performance, but yeah, 3d still is way slow. dang. | 21:51 |
| tormod | kees: I know, it's just so handy :) | 21:52 |
| tormod | is it faster with EXA for you? | 21:52 |
| kees | exa is faster than uxa, but I didn't compare old driver to new driver with exa. nothing jumped out at me. I get about 2400 fps with glxgears on exa, and about 900 on uxa | 21:53 |
