The RISC-V instruction set architecture (ISA) has been gaining popularity due to its customizability.
In an interview on the YouTube channel ‘Mastery Learning’, Linux creator Linus Torvalds noted the hard differences between hardware and software developers: “There’s a fairly big gulf between the Verilog and even the kernel, much less higher up the stack where you are working in what [is] so far away from the hardware that you really have no idea how the hardware works”
Despite RISC-V’s popularity, it’s not at the performance level of current x86 and ARM CPUs. Torvalds hopes that new architectures like RISC-V will be accepted, even if mistakes are made.
