OpenPiton is a research platform from Princeton University [1]. "OpenPiton is the world's first open source, general purpose, multithreaded manycore processor. It is a tiled manycore framework scalable from one to 1/2 billion cores." Add OpenSBI support for OpenPiton. As it is based on ariane core, it reuses the platform code from arine project.

OpenPiton FPGA SoC Platform
|
|
========================
|
|
OpenPiton is the world's first open source, general purpose, multithreaded
|
|
manycore processor. It is a tiled manycore framework scalable from one to
|
|
1/2 billion cores. Currently, OpenPiton supports the 64bit Ariane RISC-V
|
|
processor from ETH Zurich. To this end, Ariane has been equipped with a
|
|
different L1 cache subsystem that follows a write-through protocol and that has
|
|
support for cache invalidations and atomics.
|
|
|
|
To build platform specific library and firmwares, provide the
|
|
*PLATFORM=fpga/openpiton* parameter to the top level `make` command.
|
|
|
|
Platform Options
|
|
----------------
|
|
|
|
The *OpenPiton* platform does not have any platform-specific options.
|
|
|
|
Building Ariane FPGA Platform
|
|
-----------------------------
|
|
|
|
**Linux Kernel Payload**
|
|
|
|
```
|
|
make PLATFORM=fpga/openpiton FW_PAYLOAD_PATH=<linux_build_directory>/arch/riscv/boot/Image
|
|
```
|
|
|
|
Booting Ariane FPGA Platform
|
|
----------------------------
|
|
|
|
**Linux Kernel Payload**
|
|
|
|
As Linux kernel image is embedded in the OpenSBI firmware binary, Ariane will
|
|
directly boot into Linux directly after powered on.
