A Big Comparison Of The AMD Catalyst, Mesa & Gallium3D Drive

The binary drivers are also multi-threaded, which helps to hide CPU overhead *if* you have at least 2 cores.

Multithreading mostly helps when drawing is the bottleneck, however, but some of the initial profiling efforts suggest that state changes may be a bigger time sink than drawing right now. Not sure if that has been confirmed though.

Perhaps a stupid question, but why aren't the FOSS drivers multi-threaded yet? It feels like a shame to me, sitting on an Core i7.

It would make sense to run a window manager which switches compositing off for full-screen apps.

It's 2011, after all. If compiz can't cut it, use something more sane.

+1

I'm not using Compiz for two simple reasons:
1) It's to big a hit on performance
2) I still haven't seen a good (enough) use for it

Just curious, just how many gigs would cloning linus' git bring?

Well if you don't care too much about the history, you could just use `git clone -depth 0` to get the most recent head and only that; shouldn't be appreciably bigger than the unpacked kernel.

i think ubuntu has mainline drm next build here http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/

[agd5f]

is the branch in drm-next? or is git the only way?

That's a ddx (xf86-video-ati) branch, not the kernel:

http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/log/?h=kms-pflip

[agd5f]

pageflipping requires the kms-pflip branch of the ddx and is on by default.

Use closed source then?

[RealNC]

yeah thats really an answer!
are they in linux-next?does xorg-edgers use drm-next?
thats proper community support u would never get from a closed source dev!
thanks

With closed source I can at least update the GPU driver without needing to update the whole freakin' kernel to an experimental, pre-beta version

[pingufunkybeat]

They in the kernel. Does xorg-edgers provide kernels?
