Documentation/gpu/amdgpu: Add programming model for DCN

2024-10-24T22:07:05Z

One of the challenges to contributing to the display code is the complexity of the DC component. This commit adds a documentation page that discusses the programming model used by DCN and an overview of how the display code is organized.

Documentation/gpu: Add an explanation about the DCN pipeline

2022-09-01T19:09:39Z

In the DCN code, we constantly talk about hardware pipeline, pipeline, or even just pipes, which is a concept that is not obvious to everyone. For this reason, this commit expands the DCN overview explanation by adding a new section that describes what a pipeline is from the DCN perspective. Changes since V1: - Rewrite the first paragraph that describes AMD hardware pipeline.
