Hi Xavier, Just wrapped up efforts to experiment with hard TEMAC support in 2.4 kernel ( previev kit from Montavista ). DENX 2.4 distro should not be different.
Here are my experience with ML403 board: Configure kernel for only eth driver offered for ML300 / ML403 ( soft EMAC - 10/100Mb on-chip eth ). After updating kernel tree with the BSP using xilinx patch script for ML403, hard TEMAC driver will end up in /drivers/net/xilinx_gige ( supported soft MAC driver ends up in /drivers/net/xilinx_enet ). >From here 2 options: a) rename xilinx_gige folder to xilinx_enet and build kernel b) modify config.in script for kernel network configuration and makefile for building net driver by addidng new GIGE option >From my undersanding part of driver code for gige ( adapter.c ) is PHY specific and supports Marvel's PHY on ML403 board. Never looked more what it does ( phy interface should be common to all PHYs ? ) but if you use different PHY maybe you'll have to do some coding here ?! ( look for the comments in the driver ) Oh yes, my tree was missing gmii.h file ( found it throuh google - don't remember from where - first google hit :) ! Did some test measurement and comparison with soft EMAC against hard TEMAC + PLB TEMAC and defualt SG DMA mode (3): Amazing performance increase: close to 100% on tcp ( netperf and netio shows over 11000KB/s for max packet size of 32K on 100Mb link ) Hope this helps !
