I want to run 3D application which is developed by EGL/OpenGLES through weston-launch, it failed because the graphics driver is not right.


I have some questions for help.


1.Is DRM  must for weston(compositor),how to setup DRM?


2.Does GPU kernel drvier consist of kernel/driver/gpu/Vivante(Vivante.ko??) and of kernel/driver/gpu/drm/Vivante(DRM_Vivante.ko)?


3.Does user side drvier consist of EGL/OpenGLES? architecture is Application⇒EGL/OpenGLES/⇒libDRM⇒DRM_Vivante.ko⇒Vivante.ko⇒VIV-GPU?
