Hi Sir
The suggestion is you can use this AN 829: PCI Express Avalon -MM DMA Reference Design to test on your system.
Below is the document and design link:
https://www.intel.com/content/www/us/en/design-example/714948/arria-10-pcie-gen3-x8-dma.html
The design includes a high-performance DMA with an Avalon-MM interface that connects to the PCI Express Hard IP core. It transfers data either between on- chip memory and system memory or external memory and system memory. The reference design includes Linux software drivers that set up the DMA transfer. You can also use the software driver to measure and display the performance achieved for the transfers.
