WebMemory buffer allocation is driver-dependent and described in drm-memory (7). You need to create a buffer big enough for your selected mode. Now you can create a framebuffer object that uses your memory-buffer as scanout buffer. You can do this with drmModeAddFB (3) and drmModeAddFB2 (3). As a last step, you want to program your … WebThe DRM layer provides several services to graphics drivers, many of them driven by the application interfaces it provides through libdrm, the library that wraps most of the DRM ioctls. These include vblank event handling, memory management, output management, framebuffer management, command
