LE builds mainline kernels with lima/panfrost or uses the mali kernel driver (depending on which VIM board is the target). It’s not a particularly complicated recipe, although G12 hardware requires you to track the bleeding edge of mainliine kernel development and things are not fully complete - lots of work in progress which is either exciting or depressing depending on your perspective.
If we talk about VIM1 then they do have a working VPU, I assume it is for kernel 4.9, so my next question would be is there vpu driver available for 4.9? also I found something they build which says license = ‘nonfree’.
Thanks for always supporting me learn more about the current status of the drivers.
