RM will propagate the update to all channels using the provided VA space.
All channels must be idle when this call is made.
If the pageDirectory is in system memory then a CPU physical address must be
provided. RM will establish and manage the DMA mapping for the
pageDirectory.
Arguments:
vaSpace[IN} - VASpace Object
physAddress[IN] - Physical address of new page directory
physAddress[IN] - Physical address of new page directory. If
!bVidMemAperture this is a CPU physical address.
numEntries[IN] - Number of entries including previous PDE which will be copied
bVidMemAperture[IN] - If set pageDirectory will reside in VidMem aperture else sysmem
pasid[IN] - PASID (Process Address Space IDentifier) of the process
corresponding to the VA space. Ignored unless the VA space
object has ATS enabled.
dmaAddress[OUT] - DMA mapping created for physAddress.
