Mesa 9.0 Officially Released, Supports OpenGL 3.1

[curaga]

I believe the hw still has it, even in hd7k: http://www.amd.com/us/products/deskt...on-7770.aspx#2

You're right though, that the radeon driver doesn't use it for >= r500.

If there's really an old-school overlay there, then why doesn't the driver expose it? I know it doesn't work in a composited environment, but still, open source drivers usually strive to support everything the hardware is capable of.

The intel driver still has overlay support, I can use it on my netbook. No, or negligible difference in CPU usage though. But I'll have to compare image quality, maybe the overlay uses better scaling than bilinear. Not that it matters much on a tiny netbook screen (8.9'', oh how I wish such netbooks were still being made, I would kill for a 8.9'' ValleyView netbook...)

First time I hear someone saying that

OpenGL renderer string: Gallium 0.4 on AMD RV770
OpenGL version string: 2.1 Mesa 9.0
OpenGL shading language version string: 1.30

Hmm, no still OpenGL 3.0?

[droste]

for opengl 3.0 you need a kernel >= 3.6

Ah, thanks.
I'm still on 3.5.

Radeon FOSS. XV output is at 0.5% cpu, GL output is 35%. Hardly negligible, and the difference was much greater on older cards (this is a HD4k).

I just have intel integrated graphics (ivybridge) and opengl output's cpu usage isn't noticeably higher than xv (both low), it depends on the driver.
