supervisor: Add an example on the HSM extension2024-12-05T15:02:51ZMiquel Sabaté Solàmikisabate@gmail.com2024-12-05T14:34:33Zurn:sha1:76169cd214e4830a523c8c2ee7bbddc04b4253df
The HSM extension from SBI v2.0 allows a supervisor to manage the state
of harts on the system. Moreover, it also guarantees that only one hart
makes it into the booting stages of the supervisor, and it's up to the
supervisor to wake up the rest through the HSM extension.
I have added an example which showcases this extension in different
ways, and it finally shuts down the machine.

Remove old test code2024-12-05T15:02:51ZMiquel Sabaté Solàmikisabate@gmail.com2024-12-04T20:42:37Zurn:sha1:f463d544793ff83efd8b95d0bce5ec80fd8170f3
There is some code that I had there after messing with some of the
topics on Uros' blog (https://popovicu.com/), but that became irrelevant
after working on some other projects (e.g. fbos) or on other examples.
This commit also brings about a major overhaul on the structure of the
project. Hopefully it's now at a more ready state.

linux: Add a program to test the hwprobe syscall2024-12-05T15:02:50ZMiquel Sabaté Solàmikisabate@gmail.com2024-11-20T15:40:31Zurn:sha1:bab3fdfd61b3488e1879bc3e53ac17f41d2e8b67
RISC-V on Linux has a hwprobe system call which allows you to discover
what is supported by the running kernel.

This comes in the form of a simple kernel module which iterates over
CPUs and prints the contents of some device tree nodes.

It will be something more than just messing around with RISC-V stuff.
