So any userspace apps that only support fbdev (3D GFX) can still function fine by utilizing /dev/fb0 instead of making direct DRM calls. But, the system still supports full DRM. What prevents other apps from using DRM directly? Or am I misunderstanding it? -- Denys On Fri, May 01, 2015 at 11:38:10AM -0400, Cooper Jr., Franklin wrote: > All platforms are using DRM. > > However, am335x and am437x are using what is called FBDEV emulation.
