I've seen that too, I'm (very) cautiously optimistic. Ideally, ARM would be doing a bunch of the development work and actually ensure that the driver support is ready to be upstreamed on day 1 (like what AMD pretty much does AFAIU). However, the Mali-G610 (used in the RK3588) is still not supported despite being released in 2021. ARM's "work with Collabora" started before the release of the Mali-G610, so the fact that we're so far from upstream support even after this many years of development seems like a bad sign. I don't understand why future Mali architectures wouldn't also take 4+ years unless ARM really really steps it up.
