[PATCHv11 0/3] Intel FPGA Video and Image Processing Suite




From: Ong, Hean Loong <hean.loong.ong@xxxxxxxxx>

The FPGA FrameBuffer Soft IP could be seen  as the GPU and the DRM driver 
patch here is allocating memory for information to be streamed from the 
ARM/Linux to the display port. 

Basically the driver just wraps the information such as the pixels 
to be drawn by the FPGA FrameBuffer 2.

The piece of hardware in discussion is the SoC FPGA where Linux runs on 
the ARM chip and the FGPA is driven by its NIOS soft core with its own 
proprietary firmware.

For example the application from the ARM Linux would have to write 
information on the /dev/fb0 with the information stored in the 
SDRAM to be fetched by the FPGA framebuffer IP and displayed 
on the Display Port Monitor.
