Nvidia Tegra K1 (T124/T132)

GPU
Uses Nouveau for GPU acceleration although at the moment it's broken on upstream Mesa.

Tegra T132
A variant of the K1 with dual 64 bit 2.5GHz Denver cores exists called the T132, however this was only ever used in the Nexus 9 and low volume prototypes. Aside from the CPU cores and some clock tree changes it seems to be identical to the T124.
