How does hardware video acceleration work on ARM? I would like to install Fedora on a Raspberry Pi, but first I would like to make sure I can take advantage of hardware video acceleration. Most likely ARM GPUs don't support VAAPI and I don't think there are tools equivalent to vainfo and intel_gpu_top. I'm looking for someone who can provide me with information on this topic 🙂 Thanks

When you say "how", you're actually for the description of HOW it works, but rather if it works, right?

Well it depends on the chip, which you don't mention.

I probably didn't express myself well. I meant to ask how it's possible to verify the functioning of hardware video acceleration on ARM SoCs. It seems that the tools used for Intel, AMD and NVIDIA GPUs are not suitable for this. Regarding the model, I would be specifically interested in the SoC of the new Raspberry Pi 500+ (I have no idea what model it is).

RPi have perfect support because they actually upstream their own drivers for all their hardware.

Thank you for all!

And I would also like to understand what the environment variable is that identifies the correct driver (assuming one is necessary).

It's not an environment variable, it's the kernel detecting and loading the proper modules that hand off acceleration to userspace driver packages like Mesa.
