Thanks Alan and Vladimir!These are very effective clues to help me understand
the whole architecture, but I will need some experiments! :D
I may continue with this thread later to ask questions about the main problem
discussed here (i.e., turning off the screen), if I find my approach feasible!
I think that the kernel structure storing
the display state is `struct drm_crtc_state`, particularly, its `enabled` and
`active` fields.
There exists a `linux_pm` mailing list which seems to be related to my
question. But it seems to be for development purposes, and not for learning!
Where do you think I can ask the
gpu/power-management related questions at the kernel level?
There is no harm in asking - most developers had to learn at some stage.
But I would expect people on linux_pm would be focused on issues other
than GPU power management.
