Help me understand this better.
From what I have read online, since arm just licenses their ISA and each vendor’s CPU design can differ vastly from one another unlike x86 which is standard and only between amd and Intel. So the Linux support is hit or miss for arm CPUs and is dependent on vendor.
How is RISC-V better at this?. Now since it is open source, there may not be even some standard ISA like arm-v8. Isn’t it even fragmented and harder to support all different type CPUs?
i’ve had the same thought lately. the common arm design approach around the bootloader seems to turn old Android phones and tablets into e-waste sooner than necessary, in theory they could all run Linux and be useful for another ten years. but it’s hard enough to port mainline Linux to Android devices, and almost impossible to get all the included hardware working properly
