PS3 GPU DRM Driver

Introduction

• We really need a proper GPU DRM driver for PS3.
• The problem is that Linux kernel DRM framework is very complex and not well documented.

Linux Kernel DRM Framework

KMS

• CRTC -> Encoder -> Connector

TTM

• Manages memory: video memory, GART memory and system memory.
• Nouveau DRM driver e.g. manages video memory globally per device. We cannot do it because each context has its own video memory.
