One interesting use-case that's been on my mind for some time is if it would be possible to provide a CRTC via DRM that isn't part of the SoC or DRM "device" but which can display a framebuffer prepared by the DRM framework. In other words I would like to use the Tegra hardware to render content into a framebuffer (using potentially the 3D engine or HW accelerated video decoding blocks) but display that framebuffer with a CRTC registered by a different driver (perhaps provided by a PCIe or USB device). I think such a setup would be possible if the CRTC registration can be decoupled from the DRM driver. Perhaps sdrm even supports that already? Thierry
