*Wupper: PCIe DMA Engine for Xilinx FPGAs :: Software details

Device Driver

There are two drivers available:


The cmem driver allocates a chunk of memory by means of the cmem driver.


The Wupper driver initializes the card(s) and allows access to the registers. It also has functions to initiate DMA transfers.

The drivers 'wupper' and 'cmem' can be verified with 'cat /proc/cmem' and 'cat /proc/wupper'.

There is a set of applications available in wupper tools. This demonstrates the functionality of the driver.
