Open FPGA Stack (OFS) is an open-source solution that provides a hardware and software framework for building your shell design and subsequently your workload.
OFS provides reference shell designs targeting different Intel® FPGA devices with upstreamed drivers and management software tools.
To find out how easy it is to use OFS for your custom applications, please go to https://ofs.github.io/.
To find information on the latest releases, go to the Discussions Tab in the OFS GitHub repository.
Accessing OFS ingredients to use within the development framework is easy. The github.com/OFS site provides all the hardware and software repositories in one location.
| Development Focus | Repository Folder | Description |
|---|---|---|
| Hardware | ofs-agx7-pcie-attach | Provides RTL, unit tests, and build scripts to create an example Intel® Agilex® 7 FIM and is leveraged as a starting point for a custom PCIe Attach design. The reference FIM can be built on multiple board targets: -Intel® FPGA SmartNIC N6001-PL Platform -Intel Agilex 7 FPGA F-Series Development Kit (2x F-Tile) -Intel Agilex 7 FPGA I-Series Development Kit (2 X R-Tile, F-Tile) |
| Hardware | ofs-f2000x-pl | Provides RTL, unit tests, and build scripts to create an example Intel® Agilex® 7 FIM and is leveraged as a starting point for a custom SoC Attach design. The reference FIM targets an Intel® FPGA IPU F2000X-PL Platform. |
| Hardware | ofs-d5005 | Provides RTL, unit tests, and build scripts to create an example Intel® Stratix 10® FIM and is leveraged as a starting point for a custom PCIe Attach design. The reference FIM targets an Intel® FPGA PAC D5005 development board. |
| Hardware | oneapi-asp | Contains the files to generate the support package that works with the reference shells and allows you to use OneAPI. This is an optional repository for developers interested in OneAPI |
| Hardware | ofs-fim-common | Provides RTL components that are shared among all new platforms that are introduced in OFS. This folder is a subumodule in each platform repository folder. |
| Hardware | examples-afu | Provides simple Accelerator Functional Unit (AFU) examples you can use as a template for starting your own workload design. |
| Hardware | ofs-platform-afu-bbb | Contains the hardware code to build a standard interface between the FIM and your workload. |
| Software | linux-dfl | This repository is a mirror of the linux.org Git site and contains the most up-to-date drivers that are being developed and upstreamed for OFS platforms. |
| Software | meta-ofs | This repository provides the Linux® DFL kernel and the OPAE SDK for the Yocto® Project. |
| Software | opae-sdk | Contains the ingredients to build the OFS Open Programmable Acceleration Engine (OPAE) Software Development Kit which provides APIs and userspace tools for OFS FPGA management. |
| Software | opae-sim | This repository is used to build the AFU Hardware/Software Co-Simulation Environment workload developers can use to ensure their AFU can work with the OFS software stack. |
| Software | linux-dfl-backport | A place for finding and leveraging out-of-tree backported drivers for older OS versions . |
| Software | opae-legacy | Supports OFS platforms built on the legacy version of OPAE software. Not used in current OFS designs |
| Documentation | ofs.github.io | Contains the hardware and software collateral that surfaces on the OFS website: https://ofs.github.io |
