The AMD R600 Gallium3D Driver Is Becoming Quite Fit

Also, since VDPAU is being hacked on by a non-AMD programmer on a voluntary basis I'm very curious if it actually ships in a usable state any time soon (if at all). Until then, pretty much all fullscreen youtube video will be choppy and throttle the CPU.

Yeah, it's pretty fit and fast, once you:
*Turn off SwapbuffersWait
*Force off DRI vsync
*Build the driver with -march=native -O3 -flto
*Compile own kernel with full preemption model
Unfortunately, even then, bug 37168 keeps me on Catalyst. Every few days I try the latest git master stuff and latest kernel to see if it fixes the bug, but nope. That makes r600g unusable for me.
I could go back to mesa 7.10.2 where the bug doesn't manifest, but then the performance is horrid, and it doesn't work with the other 3D apps I run.
It's kinda like how wine works: app "foo" runs fine with wine x.y.z, but with wine x.y.z+1, app "bar" runs fine but "foo" is broken. So you either `make install' a different version of wine each time you want to run one of the different apps, or you just give up and say, eh, too many regressions for me, goodbye.

Well I have a HD4330 and I've been using the R600g driver on my laptop for several months now. I keep the power profile on low and the battery life is only ~10 minutes shorter than with catalyst.
GPU temp idles around 55C, system temp around 40C, both of which are -IMHO- damn good.

The power management is handled by kernel, nothing to do with Gallium3D.
Originally posted by LibertyZero View PostThe "low" setting in radeon power management works great but it's still a long way to the blob.
Because, in my case (RV770), 'low' mode freeze my system. I want to know if there is a real difference between 'low' and 'mid'.

C (pushing the system temperature well beyond 40? C, too hot to work on) while Catalyst manages to keep it at a "refreshing" 55? C (with a respective system temperature of about 27? C).
Other than that it's nice to see the driver progressing

It's a shame that the article forgot to name Dave Arlie since he is *the* one working on it continuously.
Of course, independent contributors sometimes commit patches. Especially Henri Verbeet worked quite a lot during this spring, as well as Christian Konig.
Marek implemented all the ogl functions in not just mesa/gallium but in r600g, too.
Unfortunately, Alex seems to only add new chips and fix some bugs, occasionally. However, I think he tends to work more on the kernel and ddx side, hence I'm definitely not saying he's lazy.
It's a real pity that Jerome is not as active this year as he was in the previous one. He's probably working on something else or he'll just come with something big one day.
Big kudos and thanks to all contributors! Your work is very much appreciated!

The AMD R600 Gallium3D Driver Is Becoming Quite Fit
Phoronix: The AMD R600 Gallium3D Driver Is Becoming Quite Fit
One of the features of the soon-to-be-released Mesa 7.11 is a much more mature ATI/AMD Radeon "R600g" Gallium3D driver. This driver has received much work over the past six months and is becoming quite fit...
