Hi Ramon, we have been internally talking about splitting DMA handling out of driver. It is also about taking out axi dma out of axi emac driver. I have already asked Ashok to take a look at it but I expect it is not that straightforward process as it could be. That's why I asked Ashok to send this initial version to get at least one configuration going and start to look at u-boot dma framework to be able to get axi dma out of axi emac and mcdma out of mrmac driver. Then we should be able to use mcdma with axi email and axi dma with mrmac. Would be wonderful if you can test this configuraiton on your HW with mcdma wired and definitely would be great to cooperate on dma separation via u-boot dma framework.
Thanks, Michal
Hi Michal, I have a working driver supporting MRMAC 25Gb/100Gb using the AXI emac driver. I would love to see the DMA taken out of the driver, or supporting both options inside the driver. I will gladly help you test on our HW (VCK5000) with our specific configuration.
Thanks, Ramon
