hi, nevo
thanks for your reply.
but i will implement this on the TI omap chipset. it use the powervr 3D
accelator.
so my idear is to implement one EGL surface pool which is used to render the
buffer before it render to the
framebuffer for visbility.
because it use egl to create one surface , this surface can use opengles
accelation .after the processing,
the result can be copy to the fbdev screen surface.
is it possible or is it one way to implment such gfx driver?
