The early return inside __intel_fbc_update does not completely check all the parameters that affect the FBC register values. For example, we currently lack looking at crtc->adjusted_y (for the fence Y offset) and all the parameters that affect the CFB size (for i8xx). Instead of just adding the missing parameters to the check and hoping that any changes to the fbc_activate functions also come with a matching change to the __intel_fbc_update check, introduce a new structure where we store these parameters and use the structure at the fbc_activate function. Of course, it's still possible to access everything from dev_priv in those functions, but IMHO the new code will be harder to break. v2: Rebase.
