PetaLinux 2015.2 - Open Source macb Ethernet Device Driver has Lower Performance Than emacps Driver

描述

I am comparing the performance of the open source macb Ethernet device driver to the older emacps Ethernet driver for my application.

In testing, the macb driver has lower performance. Which driver should I use?

解决方案

Xilinx has migrated to supporting and using the macb driver and designers should migrate their designs to this driver for the best long range support.

In the initial Xilinx migration to the macb driver, the scatter-gather (SG) engine was not enabled resulting in lower performance.

This has been resolved in PetaLinux 2015.2.1.
