Reading register values on FVP

Sanu5

Hello,

While executing programs on FVP (MORELLO PLATFORM MODEL target architecture is morello-purecap) with CHERIBSD OS I like to trace the register values. Any information on how to get it please.

    Ok, well my technique will only work for FVP, but your workload probably works there too. For example, you could use `run-fvp-morello-purecap` to do that, adding the extra configurations noted in my links to make tracing work.

    If you really need to use QEMU for some reason, you probably need to ask the CTSRD-CHERI team. They have a mailing list, and a public Slack channel, for example.

    If your test is small, it may be easier to simply run it under GDB (or some other debugger). You could write a GDB script to print registers periodically (or even before every instruction), for example. This approach would also work on Morello hardware.
