Not a matter of instruction set, though. Current RISC-V designs are built from scratch by companies pretty much doing their first chip and/or design studios out of the microcontroller space, if say AMD would spend a year slapping a RISC-V insn decoder onto their existing designs that shit would fly.
I guess of the big performance vendors Quallcomm will be first, they have a bone to pick regarding ARM licensing.
They started the whole thing. They invented and implemented a whole programming language to implement the thing. Then they integrated Stylo (Servo’s CSS engine) and a couple smaller bits into Firefox which made it a hell a lot faster. Then they set Rust free and shelved Servo because from the perspective of Firefox going forwards with rewriting more in Rust would’ve been a lot of investment for diminishing returns. Stylo was the big one, enabling before unseen parallelism in rendering.
Servo, even with FSFE funding, still has ways to go. Ladybird, I wonder why they even bother. If they want a C++ browser engine that hasn’t been touched by big money then there’s KHTML, Webkit/Chromium’s direct ancestor. There’s a reason KDE dropped development: It wasn’t worth the effort. Qt wasn’t willing to pick it up either.
