Topic

Display subsystem on FPGA: from hardware to software

Introduction

Goals:

1. To help readers have the most basic understanding of the implementation of display on FPGA and display driver on Linux kernel.
2. To help readers gain basic knowledge about Linux kernel.

Brief:

1. Display technologies on Linux: FBDEV, DRM/KMS, V4L2.
2. Why do we choose DRM/KMS (Direct Render Manager/Kernel Mode Setting)? Because of its stability and variable of features.
3. 5 components of DRM/KMS: Framebuffer, CRTC, Plane, Encoder, Connector.
4. Hardware implementation on FPGA and software development.
5. What is X11? It is a protocol allowing applications to create objects such as windows and use basic drawing primitives.
6. Future plans:
   • Hardware development of GPU IP Core and Linux kernel driver development for it (12 months).
   • Integrate H264 or H265 IP core and develop Linux kernel driver for it (4 months).
   • Ubuntu rootfs porting to replace the Petalinux rootfs (on going).
