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

[heleboy]

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 Vikas,

System details are rather simple. An Fpga is connected to Xeon D-1746ter via PCIe port. Fpga can be observed on Xeon D, that means, PCIe connected successfully. Fpga has a block of memory. Windows 10/11 is running on Xeon D. We are developing a kernel driver which drives Fpga memory. 4 and 8 bytes data currently can be successfully read/write from/to Fpga.

Now, there is need to have higher perfermonce. Xeon D has Intel Quickdata Technology. I found a Crystal Beach DMA driving driver. But I don't have any details how to use it in my driver. Please if you have information, can you provide any document or guidance how to use it? Or can you guide me how to use CBDMA?

CBDMA
