History
Sean Cross ea3a473c9f reworking memory allocation 
The kernel should run in a `no_std` environment, which means it must
currently run without `alloc`. We have our own allocation methods when
running on baremetal hardware.

Begin the work to break out the allocation method so that it will work
on both desktop and baremetal environments.

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
