Video Memory Management and GPU Scheduling

The video memory manager (VidMm) is a system-supplied component within the DirectX Graphics Kernel (Dxgkrnl) that is responsible for managing a GPU's memory. VidMm handles tasks related to the allocation, deallocation, and overall management of graphics memory resources used by both kernel-mode display drivers (KMDs) and user-mode drivers (UMDs). It works alongside the system-supplied GPU scheduler (VidSch) to manage memory resources efficiently.

VidMm is implemented in the following OS files:

dxgkrnl.sys
dxgmms1.sys
dxgmms2.sys

These files are only available as part of an OS install, and aren't available as a separate download. These files are only designed to work together with the other OS files that accompany them. Graphics driver developers must not mix versions of these files.
