Good thread from an Arm power on rival RISC-V instruction set. RISC-V can be forked, which is great until it isn't. Not yet clear whether RISC-V bigs like @SiFive will create de facto RISC-V standard. Fragmentation is OK for embedded one-off chips, but terrible for ecosystems.https://twitter.com/jonmasters/status/1174744697941700608 …
Open ISAs promote a variety of solutions to the problem at hand; closed ISAs drive fragmentation unless all users upgrade simultaneously...
Meanwhile at IBM and RedHat "let's join the RISC-V foundation! And Open Source all the things! Linux Foundation I choose you!"
