GPU Memory Residency in WDDM 2.0<br />
Directly exposes c<strong>on</strong>trol over physical residency<br />
– Memory referenced by the GPU must be made “resident”<br />
No dedicated video memory <strong>on</strong> <strong>Intel</strong> processors<br />
– “Resident” resources are allocated out of DRAM<br />
OS uses up to 45% of DRAM for graphics applicati<strong>on</strong>s<br />
– Ex. 1.8GB <strong>on</strong> a 4GB system, 3.6GB <strong>on</strong> an 8GB system, …<br />
– Global limit across the system, not per-process<br />
– Rest is reserved for regular CPU/OS use<br />
