1.1.6.2. PCIe Module Device Driver Functions

  • Contains PCIe discovery, device enumeration, and feature discovery.
  • Creates sysfs directories for the parent device, FPGA Management Engine (FME), and Port.
  • Creates the platform driver instances, causing the Linux kernel to load their respective platform module drivers.
