This small series of patches adds support for the 3D engine found on NVIDIA Tegra SoCs. It builds on top of Terje's and Arto's host1x and gr2d patches. A couple of things still need to be done before this can be merged, though.
Patch 1 is the central piece of the series. It adds support for using the gr3d engine via the same DRM IOCTLs that gr2d uses. A very basic set of programs to test this can be found here[0].
Patch 2 adds support for the XBGR8888 format, which seems to be what most gr3d programs use. It also adds the RGB565 as a format supported by planes. This latter part could be moved to a separate patch, but I didn't think that was necessary.
Patch 3 finally allows buffer objects to be marked as tiled so that the display controller can scan them out appropriately.
