Dear All: I am Ginny Chen from Mediatek company.I start to work with DRM for a while and now I am evaluating our display architecture for our new SoC. I would like to adopt DRM to develop our display driver. However, in our new SoC, the input source of display engine could be memory or direct-linked with other hardwares (ex:camera sensor) which means the input source of each plane should be able to configure during plane updating. As my understanding,with currently DRM framework, the input source of plane could only be framebuffer that implies we still need to allocate framebuffer for planes which are direct-linked with other hardware engines if I want to control planes without modifying DRM framework. It will waste memory and doesn't make sense for user to notice/manage the framebuffers for direct-linked DRM planes. Do you have any ideas for such use case? Any suggestion will be very appreciated.
