I've been looking through them, and I understand what you're saying, but I recently bought a brand new Opal Kelly XEM8310 with PCIe breakout board and I'd like to get...

I've compiled and booted a 5.17.15 kernel today. Both the QDMA and the XDMA drivers compile without warning or error. I do get the same error on both kernels, 5.17.16...

Oh... that's interesting! Thank you for your contribution! Could it be you used different settings in Vivado? These are mine: ([XEM8310 User's Manual - Section 4.1.1 and Section 4.1.2](https://docs.opalkelly.com/xem8310/brk8310-breakout-board/pci-express-reference-design/ ))?...

Ok. I got it to compile on the 5.1.20 kernel (the last kernel with a 'policy' in 'struct genl_ops' in include/net/genetlink.h"), but with the 'DMA/Bridge Subsystem for PCI Express' bitfile...

> FWIW, I've ran the `xdma_mm.sh` on my machine and it finished without issues [test-6.7.0-rc1.txt](https://github.com/Xilinx/dma_ip_drivers/files/13948612/test-6.7.0-rc1.txt) . It is a dev box with `6.7.0-rc1` kernel. Still the same result: [2024011600 -...

I'm starting to get a little worried, because the [Opal Kelly FrontPanel API](https://library.opalkelly.com/library/FrontPanelAPI/annotated.html) is written by a very inexperienced programmer, copy right notice from 2004 and everything closed source, and...

> I guess this hypotheses is fairly easy to check; connect a larger/smaller BRAM and see if the test fails at a different value. I'm as inexperienced with hardware, as...

> My FPGA colleague took a quick peek at your config and commented that these transfers of 8kB might be failing due to the amount of BRAM that is connected...
