[Nouveau] Questions on GPU syncpoint handling from inside the GPU

[Fernando Sahmkow]

Hi guys how are you doing? I have some questions on how the GPU handles
syncpoints from the commandlist.

I do know the register 0xB2 is the one written in the Maxwell3D Engine. As
far as I know bits 0:15 are the syncpoint id, bit 16 is unknown for me, bit
20 is increment? What other bits are set and what should be done on
increment?

Thanks in advance.
