Seven Changes We've Been Waiting On That You Will Not Find In Linux 5.7

I know that Linus doesn't want any form of in-kernel dbus until the current performance problems have all been addressed in userland,

Is that really what's holding it up? I missed that, if so.

AFAIK yes, that's currently the main problem.

(...) which could be entirely a userspace affair.

I agree with You, but better performance is possible with hardware encoding & decoding capabilities (Tiger Lake will get AV1 decoding - Hardware lvl). Without hardware solution, "soft" acceleration overloads cpu/gpu processors ..
Do you agree with me?

I'm just about asking questions, such as what relevant hardware assist is known to exist and how much drivers actually have to do with harnessing it. I'm not trying to take a position on anything I don't know.

As for AV1, more support -- and especially by fixed-function units -- is definitely better.

Relax, while I express my hopes. You asked good questions and I answered as much as I know. I'm not expert, but I think some drivers/instructions (AMD/INTEL/AnotherOne) may be in the kernel.
