Random order between crtc vs. plane vs. connector vs. priv is tickling
my ocd nerve a bit.
Otherwise looks sensible to me.

These loops are independent from each other.
And even without this patch the order is different between
drm_atomic_helper_duplicate_state() and
drm_atomic_helper_commit_duplicated_state(). :)

Hi Benoit,

This looks good to me. I was actually wondering if private object state
was properly handled by the suspend/resume helpers no later than
yesterday. Seems you read my mind :-)

Why do you need this? We're doing a full atomic_check, and your
atomic_check should be pulling in any private state objects and
recomputing their states. This smells like papering over a driver bug.
The duplicate helpers should only need to duplicate the uapi-relevant
states, i.e. connector/crtc/planes.

I have not seen any atomic_check called during the suspend duplicate
helper. And you are correct normally the private_object state in my case
would get pulled in during a plane atomic_check but that does not happen
here in this step.
Why wouldn't we save all the "state" artifacts so that the whole atomic
state is consistent?

Yeah duplicating in suspend won't call atomic_check. Restoring the
duplicated state on resume will (or there's going to be lots of broken
drivers).

It's not needed, and might possible paper over driver bugs ...

... because of this reason. If your driver can't recompute the private
state from just the duplicated uapi-relevant states it's broken. Because
essentially the exact same thing might happen through the atomic ioctl
from userspace.
Hence my question: Why do you need this?
