All that is needed, is to compile a certain kernel module against the headers of the running Linux kernel.
Linux Kernel Driver DataBase: CONFIG_ALTERA_PCIE_CHDMA: Altera PCI Express Chaining DMA driver
As the name Xillybus sounds as if it is targeted for Xilinx only. Hello, I have been reading your article about how to transfer data from a FPGA board to a computer and I might be pretty interested by your researches. A clock cleaner is most probably necessary.
Qltera By eli on May 30th, So basically, I just ran a program that reads or writes to a file descriptor as fast as possible typically a few GBsand divided the amount of data with the time elapsed. All this holds for a 1x connection as offered by Spartan-6T. Xillybus usage example click to enlarge.
Are there any DMA Linux kernel driver example with PCIe for FPGA? – Stack Overflow
It arrives as packets which you need to handle one by one with a state machine you develop. Written By eli on March 22nd, Does anyone any idea where I can found some source?
What packet size and transfer size did you use for throughput calculations? No registration is required.
I appreciated very much. Plus copying a file or two.

The Linux Device Drivers 3rd Edition is a good resource for this. Xillybus gives you the data directly through a device file interface. Written By eli on May 26th, On the PC side, yes, you need to develop or adopt some kind of driver. There is no exact meaning to packet size and transfer size when working with Xillybus, because the system presents a stream interface.
Moreover, are you the one who coded the driver on Linux? As for the throughput:
