WDDM 2.0 - o čom to vlastne je?
Chalani, chvíľku hľadám ale akosi neviem nájsť užitočné informácie - poznáte túto technológiu?

Nevies najst? A ako si hladal? Asi dost dobre ne.
WDDM v2 supports two distinct models for GPU virtual addressing, GpuMmu and IoMmu. A driver must opt-in to support either or both of the models. A single GPU node can support both modes simultaneously.
GpuMmu model
In the GpuMmu model, the video memory manager manages the GPU memory management unit and underlying page tables, and exposes services to the user mode driver that allow it to manage GPU virtual address mapping to allocations.
IoMmu model
In the IoMmu model, the CPU and GPU share a common address space and page tables.
Proste driver si moze povedat ci bude pouzivat onboard VRAM alebo zdielanu RAM (kde VRAM sluzi ako buffer).
