Hi,
I think am trying to get DRI OpenGL ES 2 working on a Tegra 3 device. Specifically, I want to be able to render GLES to the screen without having to use X. I want to use up the whole screen, in other word, I do not need any form of windows or a desktop environment. I have done a lot of reading and have found that this process is supposedly called DRI. I have read that a lot of work has been done on creating an open-source driver for the pre-K1 Tegras like the 3. As far as I understand a DRM driver is crucial for this and the latest Linux kernel seems to include this driver. I have managed to build the kernel with it and it seems to be running just fine on my board. Furthermore I have managed to compile libDRM with 'experimental' Tegra support. My problem now is that it does not appear as if though Mesa has a driver for the Tegra, am I correct? I have found the https://github.com/grate-driver/mesa fork that supposedly does but it is rather old and does not seem to be maintained anymore. I have not tried compiling it yet but from the commits it does not look as if though it ever really worked properly. My question now is what do I now, give up? Also, what is the purpose of all the DRI components except Mesa being ported to the Tegra, does that help in any way?

Adding Erik and Thierry, who probably know a lot more about this.
AFAIK Tegra2/3 used an ISA more akin to the NV30/NV40 family, but probably not similar enough to just reuse nouveau's nvfx_vert/frag stuff wholesale.
Are you interested in helping along, or were you just trying to figure out if it was in a usable state right now?
