No, it doesn't expose just one function. There are many functions that can
be exposed by the display driver. The DrvEnableDriver function fills in a
table of pointers to these functions, allowing the upper level APIs to call
them. DrvEnableDriver is the only one called directly, but the rest are
still called through the function pointers.

Hi Dean,

I have one more doubt.When I am testing Direct Draw test.I am getting
this Failed message saying that "Failed to retrieve DirectDraw ApiSet
address (ordinal 2.)" and "Unable to initialize GWES hook object".Can
u tell me whether is it because of any hardware dependencies ?
I am sending the log of this test.

Hi Dean this one is for you.

Can you please tell me how an application is talking to the display
driver.

You know that Display driver is not a stream interface driver so it
does not have any exposed functions like INIT,DENIT,OPEN ,CLOSE.
rather it exposes only one function i.e DrvEnableDriver.

It is pretty complex to under stand how the upper layer(MDD for this
GPE classes) is talking to the lower layer (i.e Hardware).

Can you help me understand this?

Thanks in advance.

Thanks for your reply Dean,

What I meant for DrvEnableDriver was that Like INIT,DEINIT display
driver exposes only one function which in turns return a pointer to an
array of some 27 function pointers.
Now when an application calls a display driver to draw say a POLYGON
with certain parameters how this will be called by upper layer and
ultimately how it is going to be drawn through hardware(communication
b/w DISPC,Framebuffer,LCD) ?
