| To make it easier task are categorized into different levels: | ||
|
|
||
| Starter: Good tasks to get started with the DRM subsystem. | ||
|
|
||
| Intermediate: Tasks which need some experience with working in the DRM | ||
| subsystem, or some specific GPU/display graphics knowledge. For debugging issue | ||
| it's good to have the relevant hardware (or a virtual driver set up) available | ||
| for testing. | ||
|
|
||
| Advanced: Tricky tasks that need fairly good understanding of the DRM subsystem | ||
| and graphics topics. Generally need the relevant hardware for development and | ||
| testing. | ||
