ARM will replace x86 and RISC V will move into ARM's old slot.

RISC V is what you’re looking for

[–] sabreW4K3@lazysoci.al 3 points 4 months ago

It's not even the first time 😭

... when it is actually usable one day.

The big problem of RISC-V is the fragmentation of the market, and it is not even a big market to start with.

RISC-V has already been ruined by a zillion proprietary vendor extensions.

[–] sabreW4K3@lazysoci.al 1 points 4 months ago (1 children)

Can the extensions not be replaced?

[–] refalo@programming.dev 2 points 4 months ago (1 children)

no it's part of the physical hardware design

[–] sabreW4K3@lazysoci.al 0 points 4 months ago (1 children)

What I mean is, given the open source nature of RISC V, if someone puts out a chip with a proprietary extension, isn't it likely that there will be a rip off that does the same but in an alternative manner? Like how there's tonnes of Raspberry Pi like boards available.

The RISC-V is an extensible ISA, so yes. All those vendor extensions are optional, when fabricating the processor, which can be replaced by other extensions over time.

Both Intel and AMD have had vendor extensions in the designs that they no longer use, even ones that have been "retracted" (i.e whatever in the heck Intel is doing with their AVX extensions).

But yeah, currently, there are a lot of proprietary extensions, which could still be declared as open hardware as well. So yeah.

I'm honestly surprised that RISC V wasn't licensed so that it was only open architecture.
