ofs-2024.2-1 is Released!

[badanur]

We are pleased to announce the ofs-2024.2-1 release of the Open FPGA Stack to GitHub. This release provides both the software and hardware infrastructure for the following reference FIMs:

1. Agilex^® 7 PCIe Attach reference designs for the following targets:
   • Intel® FPGA SmartNIC N6001-PL/N6000-PL Development Platforms
   • Agilex® 7 FPGA F-Series Development Kit (2x F-Tile)
   • Agilex® 7 FPGA I-Series Development Kit (2xR-Tile, F-Tile).

What's New

• Agilex® 7 PCIe Attach
  • Quartus Version moved to 24.1
  • I-Series Development Kit Reference FIM support for PCIe 1xGen5x16 and PCIe 1xGen4x16
  • OFSS updates to streamline the FIM build flow
  • Default PCIe Subsystem changed from "Intel FPGA IP Subsystem for PCI Express" to AXI Streaming Intel FPGA IP for PCI Express.
  • Default IOPLL clock frequency increased to 500MHz.
  • FIM clock made independent of the PCIe clock
  • PF/VF MUX is now hierarchical. If the width of the buses being multiplexed is too large for a single level, the MUX automatically generates a binary tree.
  • New support for multi-link AFUs in the FIM and OPAE. An AFU connecting to multiple PCIe links (e.g. 2xGen5x8) can be configured to behave as a single device in OPAE.
  • The OFS driver package is now built in the linux-dfl-backport repository, which points to older kernel versions. This change was necessary to mitigate potential issues in relation to core kernel packages that exist on a standard Red Hat 8.10 distribution installation. Installation instructions regarding environment setup and repository links can be found in the Software Installation Guide, and the newest version of the installer (provided in the assets at the bottom of this release page) point to the backport repository for this release.
