Hi All: I have some confused for the GEM buffer object. There must be one GEM buffer object for the framebuffer to be displayed on screen, right ? And for every window, there is also one GEM buffer object, right ? If so, my question is:
Is the GEM buffer object for the window (not direct rendering, just for 2D X client window) just pointed to some part of the displayed framebuffer, and any drawing operation is happened on the framebuffer ? Or another new memory is allocated for window and then at some time the buffer object for window is copied to the displayed framebuffer ? Thank you in advance. Best Regards, Jacky
