Description

How do I configure the Xilinx HWICAP device driver for my Linux kernel?

Solution

The HWICAP Linux device driver is only valid for MicroBlaze-based designs. 

For ARM-based designs, please use the "Xilinx Device Configuration" driver located under Device Drivers -> Character Devices.

The HWICAP device driver is located under Device Drivers -> Character Devices -> Xilinx HWICAP Support

The HWICAP is treated as a standard Linux char device. 

The driver source code can be found on the public Xilinx Git repository at : https://github.com/Xilinx/linux-xlnx/tree/master/drivers/char/xilinx_hwicap
