How to add an interrupt handler to bbl #190

Open ImagineMiracle-wxn opened 4 years ago

ImagineMiracle-wxn commented 4 years ago

I want to be able to respond to the PLIC interrupt signal in bbl, how to do it?

BBL already delegates S-mode PLIC interrupts to the S-mode software, so it should just be a matter of enabling that interrupt in S-mode.

Or did you want to handle M-mode PLIC interrupts?
