It looks like this is dependent on Ville's patch
[PATCH v2 6/9] drm/i915: Pass the primary plane position to .update_primary_plane()
to actually let us do something sensible with the destination rectangle
at the hardware level. Looks like that patch has a r-b, but hasn't made
it into di-nightly yet.
Right now, can_position is used to check for the scenarios where the
primary plane is not covering the complete crtc. This could be due to
positioning or a smaller fb on primary plane.
With Ville's patch, we would be able to allow positioning to happen.
But I need it here, to create a smaller fb for 90/270 rotation.
I agree that, until Ville's patch is there, we won't be entertaining any
positioning requests on the primary plane and we will not be throwing
any error also.
But for the 90/270 testcase in kms_rotation_crc to go through, we would
need this to create a smaller fb so that we can rotate it.
Assuming Ville's patch lands first, this is
