Sean eb725ec57f xous: carton: leak memory when converting into_message() 
When converting into a message, the associated memory should be leaked
and not freed when the Carton is dropped. This is because the Message
can outlive the MemoryMessage, and the Carton is then immediately
dropped.

Xous Core

Core files for the Xous microkernel operating system.

This repository contains everything necessary to build the Xous kernel from source. It consists of the following projects:

  • kernel: core memory manager, irq manager, and syscallhandler
  • loader: initial loader used to start the kernel
  • tools: programs used to construct a final boot image
  • docs: documentation on various aspects of Xous
  • emulation: Renode scripts used to emulate Xous
  • xous-rs: userspace library

Generating an image

You can build all Xous packages by running:

$ rustup target add riscv32imac-unknown-none-elf
$ cargo build --target riscv32imac-unknown-none-elf
$ cd kernel
$ cargo build -p kernel --target riscv32imac-unknown-none-elf
$ cd ..
$ cd loader
$ cargo build -p loader --target riscv32imac-unknown-none-elf
$ cd ..

This will compile all runtime packages for riscv32imac-unknown-none-elf. Note that the kernel and loader must currently be built separately, due to the fact that they have custom linker scripts.

These need to be packaged into a loadable binary. You can generate such a binary by running the following:

$ cargo run -p tools --bin create-image -- \
        --csv emulation/csr.csv \
        --kernel target/riscv32imac-unknown-none-elf/debug/kernel \
        --init target/riscv32imac-unknown-none-elf/debug/shell \
        target/args.bin
