This is a thread about Qualcomm looking into RISC-V. Seeing how "great" their ARM-based designs are, they will manage to make a real mess out of SBI soon enough and there will be weeping and gnashing of teeth.

I'll stock up on my popcorn supplies, this will be fun to watch from a distance.

Nevermind about making a non-compliant SBI implementation.

Why make an implementation in the first place? There's no reason to use anything else than opensbi.

Because Qualcomm _really_ dislikes letting others take a look at their (usually very boring) secret sauce. Even partners working on projects shoveling revenue counted with a sizable number of digits their way.

That's also why QCSBI (or whatever they'll call it) won't be replaced by the kernel even though the architecture theoretically allows for it: That would be ceding control.
