RISC-V Proxy Kernel and Boot Loader
=====================================
About
---------
The RISC-V Proxy Kernel, `pk`, is a lightweight application execution
environment that can host statically-linked RISC-V ELF binaries. It is
designed to support tethered RISC-V implementations with limited I/O
capability and and thus handles I/O-related system calls by proxying them to
a host computer.
This package also contains the Berkeley Boot Loader, `bbl`, which is a
supervisor execution environment for tethered RISC-V systems. It is
designed to host the RISC-V Linux port.
Build Steps
---------------
We assume that the RISCV environment variable is set to the RISC-V tools
install path, and that the riscv-gnu-toolchain package is installed.
$ mkdir build
$ cd build
$ ../configure --prefix=$RISCV/riscv64-unknown-elf --host=riscv64-unknown-elf
$ make
$ make install
Alternatively, the GNU/Linux toolchain may be used to build this package,
by setting `--host=riscv64-unknown-linux-gnu`.
