no mention of AV1? Surprised since most websites including YT uses it heavily.

Maybe that part of the driver isn't finished yet?

It actually introduces new things into the UAPI because no one else did fully-stateful AV1 decode before.

Or licensed.

Isn't the whole point of AV1 that it's royalty free, as opposed to H264/265/etc?

For the codec, sure. But there can always be more restrictions on the IP block, driver code, etc.

Yeah, and the main problem with HEVC/H265 is the patent encumbrance. Very odd, but hopefully it's just coming a bit later.

It started like that. But now there are at least 2 different patent pools that want rent.

Have they successfully gotten any?

AV1 is designed to be license free, so unless they outsourced their driver development to another company I don't think there's anything to license.
