[Nouveau] [PATCH 0/2] nvc0: support for GK20A (Tegra K1)
The following 2 patches make it possible to run Mesa programs on GK20A (Tegra K1). GK20A is very similar to GK104, but uses a new (backward-compatible) 3D class as well as the same ISA as GK110 (SM35). Taking these differences into account is sufficient to successfully render simple off-screen buffers.

GK20A is mostly compatible with GK104, but features a new 3D
class. Add it to the relevant header and use it when GK20A is
detected.

[Nouveau] [PATCH 2/2] nvc0: use SM35 ISA with GK20A
