My plan is to somehow expose the panel fitter input and output sizes explicitly at some point. The output size could be expose by adding borders to the display mode structure (or some border properties if we don't want to change the user visible mode struct). And the input size could also be done via properties. > > Best regards > Akash > > -----Original Message----- > From: Chris Wilson [mailto:chris@xxxxxxxxxxxxxxxxxx] > Sent: Wednesday, February 19, 2014 1:58 PM > To: Goel, Akash > Cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx > Subject: Re: Request for feedback : New Panel-fitter property for connectors > > On Wed, Feb 19, 2014 at 06:13:53AM +0000, Goel, Akash wrote: > > > > Hello, > > > > We are planning to expose a new panel fitter property for the connectors. > > We have some use cases like a full screen video playback, where we can flip the frame buffer of any size irrespective of the pipe timings and enable the panel fitter to do scaling instead of using the GPU. > > Other use case is the Clone mode, where we can use the composed output of the LFP on the external display, with panel fitter enabled, to avoid GPU composition. > > > > Please provide inputs/comments on the same. > > > > Best regards > > Akash > > > > -----Original Message----- > > From: Goel, Akash > > Sent: Tuesday, February 18, 2014 4:12 PM > > To: intel-gfx@xxxxxxxxxxxxxxxxxxxxx > > Cc: Goel, Akash; G, Pallavi > > Subject: [PATCH] drm/i915: Added a new Panel-fitter property for connectors > > > > From: Akash Goel <akash.goel@xxxxxxxxx> > > > > Added a Panel-fitter enable/disable property support for the connectors. > > You are missing why you cannot reuse the connector property "scaling". > -Chris > > -- > Chris Wilson, Intel Open Source Technology Centre > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Ville Syrjälä Intel OTC _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
