Descriptor Heap Configurability Summary

The following table summarizes information about Shader and non-Shader visible heap support.

	Shader Visible Descriptor Heap	Non Shader Visible Descriptor Heap
Heap Types Supported	CBV_SRV_UAV, Sampler	All
CPU Page Properties Supported	NOT_AVAILABLE, WRITE_COMBINE	WRITE_BACK
Residency Management By App	Yes, app responsible	Not applicable (not GPU visible).
Descriptor Edit Support	Copy destination only, via command list update and/or CPU copy if CPU visible.	CPU read and write only. No direct GPU access. Can be used for immediate CPU copying (as a source and destination). Can be used as an update source on a command list – this will copy the descriptors into command list storage during command list record. On execution, the stored copy will get copied to the destination, which must be a shader visible heap.
