This is the Micro OS (uOS) for testing operating system features of

OpenRISC 1000 architecture. Specifically non reentrant, preemptive

multitasking microkernel. Purpose of this code is not to be a true

operating system but merely a testbench for testing the architecture,

or1ksim and software development tools (GCC, Binutils, ...).

This test OS has all necessary exception handlers to handle exceptions. There

are two tasks: one task generates data and passes that data via IPC to the

second task. Second task outputs the data via or1ksim syscall to the simulator.

Currently only OR32 is supported (exception handlers are written in

assembly). Tools required to compile sources are the latest

or32-coff-gcc, or32-coff-as and or32-coff-ld. Also make sure you undefine

VIRTUAL_MACHINE_ONLY when compiling or1ksim.
