I am not really sure, all I know is that currently the implementation has a 3rd gen Valhall running slower than a 2nd gen Bifrost on a SoC that got criticism of the GPU being quite slow for spec.
Currently the driver in terms of performance is bad as it runs and works, but results are really bad to the levels we should be expecting .
That is with a 1000 Mhz clock rate that must be at the absolute max this thing can run, and 4 generations of increment of some big claims by Arm but it runs slower than a G52mp4 and that is wow bad.
I used Armbian in the below due to ppa:liujianfeng1994/panfork-mesa
It means Wayland and is a touch faster now than a g52mp4 but prob still quite a way off what I expected and not exactly sure what driver its using does that use libEGL.so.1 or libEGL_mesa.so.0?
I might have a go with ArmNN again but may end up in dependency hell as dunno if they stopped with 20.04
Doesn’t seem all that stable though.
