Hi @sktpin,
We are looking for a XDMA driver for ARM CPU but the Xilinx one seems to be somewhat “buggy”.
The IRQ mode is not an option for us.
We are posting messages on Xilinx forum : https://forums.xilinx.com/t5/PCI-Express/XDMA-driver-issue/td-p/902373
If Xilinx cannot help us, we will modify the drivers (if we are good enough) or maybe consider xillybus.
