XDMA driver metapackage

This repository adds udev rules and dkms support to the Xilinx XDMA driver.

Usage

Preparation

git submodule init && git submodule update
mkdir build && cd build && cmake ..

Install driver

sudo make install

Create Debian package

make package

Troubleshooting

Can't build on Ubuntu 22.04 / Kernel 5.19

There is a unmerged PR on the Xilinx driver following a breaking change in the DMA API. Until Xilinx merges this, the fix has to be applied manually.

cd dma_ip_drivers
git remote add fix git@github.com:vkomenda/dma_ip_drivers.git
git pull fix
git checkout fix/dma-compat-fix-linux-5.19

Debugging

Build the module with debugging enabled

Invoke cmake with -DXDMA_DEBUG='1'.

So the preparation step from above becomes:

git submodule init && git submodule update
mkdir build && cd build && cmake -DXDMA_DEBUG='1' ..
