A linux kernel driver for PCIe - FPGA communication.

The driver is currently written for a Arria II GX dev. board using a hard IP PCI core and a QSys memory map. A block RAM is used as a ring buffer to copy data to the PC.

1. Load the sof bitfile into the FPGA either via the USB-Blaster or the web interface that boots from the reference design in flash. If the bit file loads correctly the debugging LED's will flash out a counting pattern to let you know it's alive.
2. Perform a software-reboot of the computer so the PCI bus picks up the new configuration. Keep an eye on the LED's to make sure the board didn't lose power.

1. Clone/download the repository into some convenient location.
2. Open a shell prompt and move into the repo. directory: cd /path/to/repo
3. Move into the driver folder and compile the driver: cd src/driver; make
4. Run the load_driver script as root: sudo load_driver.sh
5. Move back into the test directory. Compile the test program with: g++ -std=c++11 test.cpp -o test.out and then run the executable for some simple read/write tests.
