Hi!

I don't understand exactly the documentation, but I think
you can confirm or correct this for me...

Ordering Tables are entries in the "GPU-queue",
Commands like "Move/Clear/Load/Store-Image" are also such entries.
(a maximum of 64 entries (=linked lists) in the queue)

OT:
I start to build an OT using different GsSort... commands,
with GsDrawOT I "tell" the GPU to start drawing the list.

"Image"-Commands:
When giving such a command, would the effect be similar to the
use of GsDrawOT? (-> tell the GPU to start)


Conclusion: (assumption: the GPU is "unemployed")
-> I make a GsDrawOT, -> GPU starts DMA-Transfer and drawing...
-> I make a MoveImage, -> ...GPU is still drawing the OT...
-> I make a StoreImage, -> ... GPU finished OT, starts now with MoveImage...
-> DrawSync(0) -> the CPU is waiting for the GPU to finish drawing...
-> ...GPU finished drawing, -> CPU continues processing...

Are my thoughts right?


Thanx for your help, greetz
