Hi, I've finally managed to get HDMI working on Tegra20. Unfortunately the xf86-video-modesetting driver doesn't work on top of it yet, but I think that's a different error somewhere else and I'm still trying to figure out what exactly is going wrong. However, a framebuffer console can be run on top of it, as does a small test program that I've written for testing. The branch that contains all of this is the tegra/next branch on my personal Linux kernel tree on gitorious[0]. Some other things are included as well, such as the latest PCIe driver, an experimental draft of a NAND driver (loosely based on the U-Boot driver by Jim Lin and Simon Glass) as well as various fixes and hacks. Some of it is probably also junk that I'll throw away at some point. The branch isn't very clean, but it should work well enough for anybody who wants to give it a try. My plan was to get LVDS and HDMI to work on Tegra20 with CMA for GEM object allocations before submitting for mainline inclusion. Since all of these are now working I will clean up the branch, provide a branch with only the DRM bits into a separate branch and submit the patches for review, with the hope of getting them included in 3.8. A lot of the HDMI work has been contributed by NVIDIA's Mark Zhang, who is also busy (and apparently very close to) getting Tegra30 support working. If he can make it work, Tegra30 support can be included as well. All of that said, I invite everyone with access to Tegra hardware to give the DRM driver a spin and report back if you encounter any problems. Feel free to also drop a note on success.
