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.
