Hi Ville, Quick question here on the use case and the trigger for the LRR case which is within VRR range. Could this perhaps be used if we had a virtual mode say 40Hz that now falls in the VRR range (30 -120Hz) that is exposed through the connector mode list and then if we do a modest to 40Hz

2023-09-15 Thread Ville Syrjala
From: Ville Syrjälä Implement low refresh rate (LRR) where we change the vblank length by hand as requested, but otherwise keep the timing generator running in non-VRR mode (ie. fixed refresh rate). The panel itself must support VRR for this to work, and only TGL+ has the double buffred
