Currently the bigjoiner state copy logic is kind of a byzantine mess. Clean it up to operate in the following manner during a full modeset: 1) master uapi -> hw state copy 2) master hw -> slave hw state copy And during a non-modeset update we do: 1) master uapi -> hw state light copy 2) master hw -> slave hw state light copy I think that is now easier to reason about since we never do any kind of master uapi -> slave hw state copy short circuit that could happen previously. Obviously this does now depend on the master uapi->hw copy always happening before the master hw -> slave hw copy, but that is guaranteed by the fact that we always add both crtcs to the state early, the crtcs are registered in pipe order (so the compute_config loop happens in pipe order), and the hardware requires the master pipe has to be lower than the slave pipe as well. And for good measure we shall add a check+WARN for this before doing the bigjoiner crtc assignment. v2: Fix uapi.ctm vs. hw.ctm copy-paste fail Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220204072049.1610-1-ville.syrjala@linux.intel.com Reviewed-by: Manasi Navare <manasi.d.navare@intel.com>
