Parameters:

dev_id The raw device ID of specified Intel FPGA device.
prop The data pointer of FPGA property buffer.

Returns:

  • (0) if successful.
  • (-ENODEV) if dev_id is invalid.
  • (-EBUSY) if FPGA is rebooting.

force Abort the update process by writing register if set non-zero.

Returns:

  • (0) if successful.
  • (-ENODEV) if dev_id is invalid.
  • (-EINVAL) if bad parameter.
  • (-EAGAIN) if failed with force.

int rte_pmd_ifpga_reboot_try (uint16_t dev_id)

Check current Intel FPGA status and change it to reboot status if it is idle

Parameters:

dev_id The raw device ID of specified Intel FPGA device.

Returns:

  • (0) if FPGA is ready to reboot.
  • (-ENODEV) if dev_id is invalid.
  • (-ENOMEM) if share data is not initialized.
