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.
