Hi all,
here is a v2 of the NVDEC support series. Changes have been done to accommodate review comments on v1, and the NVDEC1 instance on Tegra194 is now supported. The series has been tested on Tegra186 on top of my/Thierry's TegraDRM v8 series (though should work on top of v7 as well).
NVDEC hardware documentation can be found at https://github.com/NVIDIA/open-gpu-doc/tree/master/classes/video
and example userspace can be found at https://github.com/cyndis/vaapi-tegra-driver
Thanks, Mikko
