       | Unfortunately I bought a bunch of Radxa Zero 3W's, which use the
       | RK3566. An older design though, from around when RK3588 was also
       | arriving. Mainline support is not that bad. But I don't think
       | there's much focus on improving it. Mostly I just want video
       | encoding; my original use case was using it as an HDMI ->
       | wireless transmitter.
       | 
       | As we head into this computing crunch, alas, these lesser chips
       | are going to be quite important. There's some really nice
       | Allwinner A733 chips too, but I don't think support is nearly on
       | par with what Collabora has cooked up for Rockchip. That's a
       | _huge_ advantage, and it 's _fantastic._
       | 
       | There was a really scary time a year ago when it felt like
       | Rockchip was going to disappear from open source. There's still a
       | question of availability of SBC systems, but where we are is so
       | much better than it looked like things were going to be, 15
       | months ago. Great follow up post here, on the post 5 days ago
       | about the great progress with video decoding going to mainline. I
       | wonder how Allwinner is doing with their A733 & maybe upcoming
       | A737. https://mastodon.social/@geerlingguy/113698847221483936

       | There's a very good support matrix, showing which kernel version
       | lands support for what Rockchip thing, that is just delightful to
       | see: https://gitlab.collabora.com/hardware-
