Radeon Gallium on ubuntu

[Zhick]

Yeah I just tried yesterday. The game menu seems to be pretty flawless as far as I can tell, but as you say it still crashes when you try to start a game.
What do you mean by "Does it still work(even with broken graphics)?"? AFAIK HoN never worked with r300g. But it's been reported to work on the r600 classic-mesa driver.

I thought I remembered someone posting a really messed up in game screenshot. Maybe it was with another driver/graphic.

Radeon R300g benchmarks coming next week finally at Phoronix.

Great, thank you Micheal.

It seems that the latest few git revisions improved gallium driver significantly. I know glxgears isn't a great way to test, but at least it is good to compare classic and gallium driver.

Here's a quick test (note that it has been done remotely via ssh, no local users were logged on):

Software is:
- latest mesa git
- xorg-server 1.7.99.901
- xf86-video-ati 6.12.192 with the vsync off patch (http://www.phoronix.com/forums/showp...8&postcount=19)

I'll report back when I test how does a 3D game (= Counter Strike) perform under the gallium.

FWIW I got a report that r300g is on par with r300c in terms of performance and even outperforms classic in more complex scenes, thanks to Dave's todays commits plus a lot of work done in the past to make this happen.

Wow.

Isn't r300 classic already more or less feature-complete (with the powersaving bits rolling into the kernel as we speak)?

If r300g is almost feature-complete too, this would only leave optimisations, right?

The goal is now to make some more games work instead of crashing or self-killing the process due to hitting an unsupported feature or unaligned vertex buffer access.

Sounds like a plan :b

I've been noticing the same thing as mentioned a few posts up with glxgears. The FPS has been slowly creeping up. Just now i tried it and the FPS is almost the same as the regular r300 driver.

Some bad news though is that HoN used to work fine in the menus but now it segfaults just as the menu is about to load.
