The Nouveau userspace (and kernel driver for that matter) don't support CUDA at this point in time. I think some work had been done on that as part of the A44 project, but I don't know exactly what the status is. Alex, do you happen to know? In order to run the proprietary userspace you'd need a copy of the nvgpu driver (and possibly other dependencies) from downstream. Porting that to an upstream kernel is, as far as I understand, non-trivial. So the bottom line is that you're between a rock and a hard place. Perhaps one alternative is to connect a discrete GPU via PCIe and use the proprietary driver for 32-bit ARM. I think people have had some success using that. That's of course not a very nice solution since it doesn't make use of the Tegra GPU and requires a lot of extra power. > As a second question, is there any roadmap for the wifi support on the TX1 > devkit? I have not looked at wifi at all. I think it's connected via SDIO, so it might be possible to get it to work with very little effort. Thierry
