I've been following this thread for a short while - thanks for the really great information! I've been tasked with getting the VPU working on a rk3399-based board with a custom distro. For user space I think I understand what's required and where to get it. For the kernel I'm a little confused on what's required.
It seems 5.8 is the place to start. That seems somewhat stable at this point, at least for some codecs. Do I need both the hantro and rkvdec drivers or is the hantro sufficient? We need h264, mp4 and mjpeg decoding and mjpeg encoding at a minimum. I may be required to backport to 5.4 but I can't tell if that would be harder than forward porting our tweaks of 5.4 instead.
I've started following the linux-media mailing list for updates. I just need some help on where the best place to start is.
Any pointers would be greatly appreciated. Thanks!
