WaitForCompletio
n
Not used This is used to suspend the PERMEDIA core until all outstanding
reads and writes in framebuffer memory units have completed. This is
intended to prevent a new primitive from starting to be rasterized
before the previous primitive is
completely
finished. It would be used,
for example, to separate texture downloads from the surrounding
primitives. The same functionality can be achieved using the Sync
command and waiting for it in the Host Out FIFO. However, using
WaitForCompletion doesn’t involve the host and can be inserted into a
DMA buffer.
