Hi Hinko,
mgb4 driver which uses XDMA in mainline kernel. Please see:

Thanks,

Hi,
here at ESS we are using https://github.com/Xilinx/dma_ip_drivers/tree/master/XDMA/linux-kernel kernel driver today with the micro TCA based data acquisition cards such as https://innovation.desy.de/technologies/microtca/boards/damc_fmc2zup/index_eng.html and https://www.struck.de/sis8300.html. The diver seems to be functioning just fine and it provides all the necessary software interfaces we desire.
Looking at the https://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine.git/ I noticed that there is a lot of effort in getting the XDMA dmaengine accepted into mainline kernel. As far as I understand one would need to develop an additional driver that utilizes the XDMA dmaengine driver.
Is there a reference implementation of a driver that uses XDMA dmaengine that is similar to the on in dma_ip_drivers github repo?
Thank you in advance!
