Host Server Environments
  • PCIe – Gen 4×16
  • Disk: Free Space up to 50GB
  • Memory: 128GB
  • BIOS: Enable IOMMU, Huge pages, PCI Reallocation, Disable PCI-ASM.
  • Supported OS: Ubuntu 22.04, RedHat 8
  • Supported Libraries & Applications: OPAE SDK, HE-Exerciser, LinuxPTP, DPDK
OFS Software
  • HE-Exerciser
      • The host interacts with the FPGA using the Linux DFL (Device Feature List) and OPAE (Open Programmable Accelerator Engine) libraries https://ofs.github.io/ofs-2024.2-1/sw/fpga_api/prog_guide/FPGA-lib-1.png
      • HE applications communicate with the HSSI, Loopback, Traffic Generator, and Memory modules within the AFU region of the FPGA.
      • The application also extends its functionality to transmit workloads over QSFP ports at various speeds.
  • DPDK-IFPGA
      • The DPDK based IFPGA libraries help to interact with Management modules.
      • The IFPGA Rawdev Driver utilizes Intel FPGA Software Stack OPAE (Open Programmable Acceleration Engine) for FPGA management.
      • Management Modules include FPGA status check, FPGA reset or reboot, PR reset, Read/Write PCI configuration space, bind or unbind FPGA with kernel drivers.
  • Linux PTP
      • The kernel exposes ToD IP as a PTP Hardware Clock to the Linux PTP stack, allowing the system clock to synchronize with the ToD information
      • The phc2sys utility to access ToD information and synchronize the system clock.

Application Stack Accelerator Function (ASAF)

  • VirtIO-net emulated PCIe devices
  • Management Tool for network datapath configuration
  • Status or statistics retrieval from Ethernet
  • Packet Processor to forward packets
  • BMC to monitor and control board components

Open FPGA Stack (OFS)

  • A Framework for custom workloads
  • Manage and access programmable accelerators using OPAE Tool
  • AFU accelerates functions on an OPAE hardware platform
  • Dynamically reconfigure FPGA parts using Partial Reconfiguration
  • BMC controls, monitors, and manages board access
