Xilinx
QDMA AIO Read
using the qdma driver, when I try to read asynchronously, my system causes a freeze then restarts.
the restart is happening from a result of the line below: rv = xcdev->fp_aiorw(xcdev->xcb->xpdev->dev_hndl, qhndl, caio->req_count, caio->reqv);
My overall goal is to read asynchronously, while also performing zero copy DMA. I turn off no_memcpy, however i believe this is only for performance testing and actually doesnt do anything besides that?
i ran into this a while back too. i never had the patience to debug it. I just don't use the AIO path.
