Introduction

...

  The Broadcom VideoCore 4 (present in the Raspberry Pi) contains a OpenGL ES 2.0-compatible 3D engine called V3D, and a highly configurable display output pipeline that supports HDMI, DSI, DPI, and Composite TV output. The 3D engine also has an interface for submitting arbitrary compute shader-style jobs using the same shader processor as is used for vertex and fragment shaders in GLES 2.0. Closed source graphics stack runs on VC4 GPU and talks to V3D and display component. Vc4 uses mesa instead of userland for graphics. Mesa is an open source software implementation of OpenGl, Vulkan and other graphics API specification. Mesa translates these specifications to vendor specific graphics hardware drivers.

Environment Setup

• Set-up Considerations

<Briefly describe and graphically depict as appropriate the equipment, communications, and network configuration of the system in a way that a non-technical user can understand>

...

<Describe how system flow is happening mentioning checkpoints which can be verified during flow to ensure system is working as expected>

• Exiting the System

<Mention the validation artifacts that are essential to ensure the functionality is working as expected. Also any limitation while closing the validation process>

Executing System

Describe the specific system function or feature in detail and depict graphically by including screen prints and descriptive narrative as appropriate. Ensure each screen print is captioned and has an associated tag providing appropriate alternative text
