I generally like the idea of centralizing this in libdrm_radeon. > The second question especialy impact the layering/abstraction of gallium > btw winsys as it make libdrm/radeon_surface API a part of the winsys. That's unfortunate, but then again the Radeon Gallium drivers have never been very clean in this regard. I guess the first one to want to use them on a non-DRM platform gets to clean that up. :) > To test you need to set ColorTiling2D to true in your xorg.conf, plan > is to get mesa 8.0 and newer with proper support for 2D tiling and > in 1 year, to move ColorTiling2D default value from false to true. > (assumption is that by then we could assume that someone with a working > ddx would also have a supported mesa) Sounds good. Note that the Mesa and X driver changes need to either continue building and working with older libdrm_radeon, or bump the libdrm_radeon version requirement in configure.ac. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
