If this would happen before I have spend two weeks converting the original Xilinx "driver" to something with at least a theoretical chance to be included into the kernel, it would be even better... ;-) > Will appreciate your review of that patch set and hopefully MGB4 driver > can be rebased on top it? As I already replied to Lizhi Hou, this new XDMA driver is at the moment unusable for most XDMA-based HW as it does not handle the user IRQs logic and as it also takes up the user IRQs register memory space, it even actively hinders other drivers to at least handle the IRQs themselves.
