I looked at DRM/KMS briefly earlier in the year and this is what made me abandon it in the end. Can you recommend any sources of information?

The atomic API and "test only commit" both sound really useful.

My main source was reading other source and sometimes asking questions in the Pi forum. The already linked kmscube shows how some of mentioned techniques work. It was then mainly following up on API calls names and parameters (DRM_MODE_ATOMIC_TEST_ONLY) to find other snippets of code that use them. Felt a bit more like code archeology :-)
