Is the situation better with Mali? This seems something that might actually improve with Nvidia. I was under the impression that ARM GPUs are currently heavily locked down anyway (in terms of open source drivers). Nvidia would presumably still be locked down, but maybe we'd have more uniform cross platform interfaces like CUDA.

Tegra open source support is great and actually supported by NVIDIA. Probably the best ARM GPU option for open source drivers.

Mali support is done by outside groups (not ARM). Midgard and Bifrost models are well supported (anything that starts with a T or G, respectively). Support for older models is a little worse, but better than some other GPUs.

Adreno support is done by outside groups (not Qualcomm) and is lagging behind new GPUs that come out considerably.

PowerVR GPUs (Imagination) have terrible open source support.

Tegra the chipset is supported by Nvidia, but even then they are not a paragon of cooperation with the Linux community. They have their own non-mainlined driver, while the mainlined one (tegra) is done by someone else.

They did contribute somewhat to the "tegra" driver at least.
