   *reads RISCV SBI spec*
   
   Hmm, is there nothing in the style of like ctrl+alt+o+f to get a supervision console? (Or other things similar to SysRq-magic)

     @yyp Well something like a serial console is somewhat part of SBI / risc-v platform, allows to pass earlycon=sbi to the kernel.

     @lanodan From my understanding, most RISC-V specifications (including SBI) don't expect any kind of input devices or special shortcuts.

     So any kind of SysRQ-magic is just using the default input driver from the kernel. This is what Linux does at least.

     It's possible that a device has an interrupt source for this use-case - check the device tree. Though I'm not very familiar with RV hardware, no idea if there exists a board with such a feature.
