The Physical Function (PF) Baseband Device (BBDEV) Configuration Application (pf_bb_config) provides a means to configure a baseband device at the host level. The program accesses the configuration space and sets various parameters through memory-mapped I/O (MMIO) reads and writes.

The parameters are parsed from a given configuration file (with .cfg extensions) that is specific to a particular baseband device, although they follow same format.

Building the PF BBDEV Config Application

Build the program by typing the make command. The result is that the pf_bb_config binary file is produced.

Usage

The application requires the name of the BBDEV device to configure. Other arguments are optional. The application executes as follows:

./pf_bb_config DEVICE_NAME [-h] [-a] [-c CFG_FILE] [-p PCI_ID] [-v VFIO_TOKEN]
  • DEVICE_NAME: Specifies the device to configure; for example: 'FPGA_5GNR' or 'ACC100'
  • -a: Configures all PCI devices matching the given DEVICE_NAME
  • -h: Prints help
  • -c CFG_FILE: Specifies configuration file to use
  • -p PCI_ID: Specifies PCI ID of device to configure
  • -v VFIO_TOKEN : `VFIO_TOKEN is UUID formatted VFIO VF token required when bound with vfio-pci
