The dpaa-im from nxp-qoriq

dpaa-im's Introduction

Dpaa-im:
  Dpaa-im is an Ethernet driver using Dpaa Fman to implement in independent mode.

Dependence:
  1. All the DPAA drivers should be disabled in kernel configuration file, the list as below:

	CONFIG_FSL_SDK_DPA
	CONFIG_FSL_SDK_FMAN
	CONFIG_FSL_SDK_DPAA_ETH
	CONFIG_FSL_DPAA
	CONFIG_FSL_FMAN
	CONFIG_FSL_DPAA_ETH

  2. Linux should be built before building dpaa-im
  3. Dpaa-im is based on linux-4.9 and linux-4.14 of LSDK release

Building:
  To build dpaa-im as a module

	cd dpaa-im
	make build KERNEL_DIR=<path-to-linux> ARCH=arm64 CROSS_COMPILE=<arm64-toolchain>
	e.g. make build KERNEL_DIR=~/linux ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

  after building, you will see module file "dpaa_eth_im.ko"
  In addition, use "make clean KERNEL_DIR=<path-to-linux> ARCH=arm64 CROSS_COMPILE=<arm64-toolchain>" to clean
 
Using:
  1. Fman firmware should be loaded in uboot.
  2. Boot up linux.
  3. In linux, run command "insmod dpaa_eth_im.ko", kernel will print:

	[    0.535089] fman_im: QorIQ FMAN Independent Mode Ethernet Driver loaded
	[    0.541782] DEV: FM1@DTSEC3, DTS Node: fsl,dpaa:ethernet@6

  4. Run command "ifconfig -a", dpaa-im ethernet(FM1@DTSEC3) could be saw, then use it as normal ethernet.
