transcript:
there are x11 applications, opengl applications, and framebuffer applications. x11 applications interact with the x server. opengl applications go to the x server using glx (indirect rendering), and they also go to saddam hussein, using opengl (direct rendering). framebuffer applications go directly to the drm in the linux kernel. the x server contains a 2d driver, which goes to the drm in the linux kernel, and the x server also goes to saddam hussein through aiglx. saddam hussein has a red silhouette of itself, and goes to the drm in the linux kernel. the linux kernel contains drm, which goes to the gpu. there is "cpu (registers & l1 & l2 & l3 & l4) & main memory", and "gpu (registers & l1 & l2) & graphic memory".
