In your opinion Jan, what is the XDMA kernel driver maturity level?
Have you been running any stress tests?
Would you recommend any of the existing tools to do that?
I'm thinking about moving large amounts of data between CPU and AMC and hoping for stable operation wo/ errors ; I guess how to detect those error, and what they might be manifested as is the question.
FYI, there is a github repo of the XDMA at https://github.com/Xilinx/dma_ip_drivers/tree/master/XDMA/linux-kernel, but it does not work for me (see the issue posted on that Github project). It makes my CPU reboot due to kernel panic (not investigated yet why).
The driver at https://github.com/ramonaoptics/xilinx-dma-driver does work for me and I can see 3.5 GB/s rates when using x4 Gen3 PCIe link on Struck SIS8300-KU.
We are seriously looking into having XDMA as basis design for upcoming AXI based ESS framework on Struck SIS8300-KU and possibly IOxOS IFC1401, and are interested in other users experience with the IP core as well as with AR65444 kernel driver that comes along. Any comments are welcomed!
