History
bunnie 900d829bf4 a lot of bug fixes in the core kernel swapper 
probably should have done this in smaller commit chunks but it
was hard to say if this was going in the right direction until now.

at the moment, system can boot and evict quite a bit of memory before
hitting a panic. The current state is that we panic on returning
from an interrupt handler that hit a swapped page.

This is a pretty decent point to check point everything. hopefully
this next arc will be a bit cleaner.

Xous Kernel

This contains the core kernel for Xous. It requires a stage 1 loader in order to start up, as it assumes the system is already running in Supervisor mode.

Building

To build the kernel, you will need a riscv32 target for Rust. Possible targets include riscv32i-unknown-none-elf, riscv32imac-unknown-none-elf, or riscv32imac-unknown-xous-elf.

  1. Decide what target you want. For simple, embedded systems this could be riscv32i-unknown-none-elf, and for more complex systems with compressed instructions you could use riscv32imac-unknown-none-elf.
  2. Get Rust. Go to https://rustup.rs/ and follow its instructions.
  3. Install the proper toolchain: rustup target add ${target_arch}
  4. Build the kernel: cargo build --release --target ${target_arch}

Using

To use the kernel, you must package it up into an arguments binary with xous-tools.

Testing

TBD
