History

Sean Cross 21a8ddd458 kernel: services: don't remap memory on intra-process lends This brings intra-process lending in-line with intra-process sending, where memory is not remapped the pointer is simply reused. We may change this at a later point in order to further enforce the concept of lent-memory-is-inaccessible, so do not rely in this behavior.

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.

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.
Get Rust. Go to https://rustup.rs/ and follow its instructions.
Install the proper toolchain: rustup target add ${target_arch}
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
