Here's the first one, NVDEC. The kernel driver is a simple Falcon boot driver based on the VIC driver. Some code sharing should be considered there in the future. The userspace driver to accompany this is a bit more complicated - I have expanded vaapi-tegra-driver[2] to support MPEG2 decoding. It should be noted that the implementation is still very clunky and has poor performance, but it's a start. This series is based on top of the "Host1x/TegraDRM UAPI" series. For testing, appropriate firmware should be obtained from a Linux for Tegra distribution for now; the GPU should also be enabled in the device tree. Series was tested on Tegra186. Thanks!
