Debug support re-using existing blocks

[likewise]

It would be very nice to have GDB debug support over JTAG using the existing work in DM/DMI/OpenOCD. A good example where the RISC-V debug module was added to the Ibex RV32IMC can be found in these last three commits:

https://github.com/majbthrd/ibex/commits/add_debug

Specifically:

majbthrd/ibex@371c4bc

It is very nice to build/upload and visually start debugging (for example VSCode) within 1 second.

Yes it is a nice option to add. It will probably require to add some logic in the processor, I am not familiar with how debugging works with RISC-V, but it is something I may add in the future (once I understand how it works !). Is there a tutorial / explanation somewhere I could start from ?
