So, do we split msm_priv->dp too? It's indexed using MSM_DP_CONTROLLER_n entries. Do we want to teach drm/msm/dp code that there are priv->dp[] and priv->edp arrays? > Why do we want to keep building something on top of this confusing > terminology knowing that it can be corrected when its fairly in the > development stage rather than realizing later it will break. > > We have only been discussing that eDP and DP are treated equally in the > DPU code and hence why do we need to distinguish. > > As per current code yes, but I cannot and probably noone else can > guarantee that in future there can be cases were we want to distinguish > the two for something. Me too. For now I see INTF_DP as a useful abstraction for 'the interface that's handled by drm/msm/dp and shares common timing requirements'. At this moment I estimate that splitting it properly into INTF_DP and INTF_EDP can bring more troubles than possible future cases. If at some point we were to distinguish DP and eDP usecases of INTF_DP, I would suggest adding is_embedded property rather than splitting away INTF_EDP. It's good to think about future cases and expansions. But it's too easy to create a monstruosos constructs supporting all possible features that no one can understand, grok and maintain. Been there, created several of them, refactored others. Let me throw in yet-another-possible-if: if at some point the hardware supported iDP using the same DP block, would you split INTF_iDP? > Thats the overally consensus within our team. > > So if this going to work smoothly by just fixing two entries in the hw > catalog I would rather do that now rather than realizing this down the > line again just to save usage of one more enum. > > > With all that in mind I'd suggest to: > > - use INTF_DP for both DP and new eDP interfaces > > - remove INTF_EDP usage from the dpu1 driver > > - add a note that INTF_EDP corresponds to older eDP blocks (found on 8x74/8x84) > > > >> > >>>>> +};
