Memory copy using Intel QuickData Technology on Intel Xeon D-1746ter

heleboy — Tue, 01 Apr 2025 12:44:03 GMT

Dear,
For a custom board with Intel Xeon D-1746ter, I am developing a DMA based application making transaction to/from FPGA board memory on Windows 10/11. After some investigation, I found DMA capability of Intel Quickdata Technology. Now, I am looking for ways to use it to make memory copy from memory to memory. I checked the EDS documentation and found the registries of Crystal Beach successfully.
When I make further investigation, I ran into following link;
https://www.drvhub.net/devices/chipsets/intel/chipset-quickdata-technology-device-3430
I understood that there is already a Windows driver. I would like to understand how to use this driver in my application.
Could you please share/provide documents or samples on how to use the driver in my application?
Could you please recommend on how to proceed?
Best Regards,
LK

Dear Carlos,
Thank you for sharing links. I have also noticed the links. I think the links are related to Linux. Mine is in Windows. At first, it is better for me to find some ready solutions in Windows. I noticed the Windows driver below.
I think it is developed by Intel.

Can you please share documents on how to use it in my application? İoctl commands and parameters?Other Windows drivers? How to use it?
Best regards

Dear Carlos,
Thank you for clarification. I see. I'll check spdk link. I saw some sample codes. I hope I can integrate it with my Windows driver.
If I run into a problem or need help, where can I contact?
