For it to look right we need mesa to call into the kernel to tell the
kernel what is the bo tiling format. We should do that for scanout

Anyway, since I do need this,

Thanks a lot! I reproduced the same results here and I think I have
figured out what the problem is. The frame buffer is always created in

Could you please check

code base.

Unfortunately no. In fact the Gallium EGL/R600 doesn't support flip on
vsync at all - eglSwapInterval is

No, I am not uploading it for every frame. It is a static texture. I am
getting only 35 FPS on a HD6460, which is path

The hack I am using to disable texture tiling is also extremely simple
(see below). It speeds up the FPS measurably, up to the extreme
case of doubling it on HD6460.
What am I missing?

Hi,
I have been running tests with Mesa 9.0 and Rdeon R600 (Radeon HD 6460) and I
accidentally noticed that a small hack I did to disable texture tiling,
actually *doubles* the frame rate. With different chips (e.g. 6750) the
difference is less pronounced, but in all cases texture tiling decreas

I am new to this list, so I apologize if the format or the subject is
inappropriate. If so, I would appreciate any advice directing me to the
appropriate place to post.
I found a configuration/build time problem with the Gallium EGL state tracker.
It fails in Mesa-9.0 where it used to work
