Re: SBI Debug Console Extension Proposal (Draft v1)
Currently this function is just a nop(). It is not needed in this revision of the extension.
The function might be called repeatedly by different threads with different values. How do you want to

Re: SBI Debug Console Extension Proposal (Draft v1)
You can easily create multiple pre-populated strings using ".asciiz" in
assembly sources. Just set the base address of pre-populated strings
once on boot hart and print from anywhere using usual 4-5

1) Use lock to serialize access to shared memory and always
