Linux and RISC-V by 2030
(lemmy.ml)
I'm planning to switch to RISC-V by 2030, and since this is new to me (I’m an old AMD64 (and i386) veteran), I wanted to ask what your thoughts and predictions are regarding performance, stability, and usability as a creator of all kinds of content, whether it’s music, movies, 3D, or watching cat videos on YouTube. I’m also planning to buy a new, fresh computer, maybe a laptop from around 2027/2028. Is that a good idea, or am I biting off more than I can chew? To sum up, I’m asking for your opinions, advice, warnings, and thoughts. Feel free to write not only answers to my questions but anything you consider important in the context of the RISC-V and Linux marriage in the near future
RISC-V is designed to be an extensible instruction set, where the base is very minimal and reduced but a plethora of extensions exist. The ISA can be small for academic and microcontroller uses, large (more than a hundred extensions) for server uses, or anything in between.
Despite the name, a powerful RISC-V server can arguably not be considered "RISC", though that term doesn't have a single agreed-upon meaning and some design characteristics strongly associated with RISC still apply such as limiting memory access to dedicated load/store instructions only rather than allowing computation instructions to operate on memory.
Also, not everything is CPU instructions. Acceleration for media codecs, for example, normally means off-loading those tasks to the GPU rather than the CPU. Even if the CPU and GPU are both part of the same SoC, that doesn't touch the CPU instruction set.
