ATI R600/700 OSS 3D Driver Reaches Gears Milestone

[agd5f]

it still only runs with --loose-binding (it still says that GLX_EXT_texture_from_pixmap is missing)

tfp only works in indirect contexts with dri1, so make sure the xserver has loaded the latest version of the 3d driver (r600_dri.so).

My guess is that interrupt support won't get enabled until the rest of the stack is working the way we want,

That sounds reasonable. Why adding more complexity as needed.

although we might start coding it sooner. I'm not expecting interrupts to add much in the way of performance (although I think they are used for sync-to-vblank) but they make debugging more complicated.

Hm, is the polling so less, that it doesn't matter?

thanks for the clarification !

it seems to be loaded:

here an screenshot for what I mean:

openarena works now

have to run it with LIBGL_ALWAYS_INDIRECT=1 to make it use hardware acceleration, otherwise it uses software rasterization (same with quake3)

a lot of glitches, but its playable at 1680x1050.

when round finishes X crashes

quake3 can run too, but soon after round start X crashes

That just leaves the intermittent geometry corruption, which I expect is going to be a real pain to troubleshoot but easy to fix once the problem is understood, plus some regressions over the last couple of weeks (eg etracer).

Yeah, that's bizarre. In my case, I seem to get geometry corruption fairly reliably with the Mesa geartrain demo, despite it being very similar internally to the gears demo which doesn't suffer from the problem. Haven't tested this on the latest version, though.

[bridgman]

When I tested today I found corruption on both engine and geartrain much reduced. The gears also spin on the cube faces with gearbox, which is a nice change

Polling vs. interrupts probably affects CPU utilization more than it affects the speed of the graphics operations.

[PuckPoltergeist]

Yes and so it's affecting overall performance. Haven't said this clear enough, my fault.

[bridgman]

If it's performance you want pull the latest drm code...

[highlandsun]

592fps for me now. Damn...

edit: geartrain has a lot of corruption when other things are happening - scrolling, mouse motion, whatever...
