DXGK_GPUPCAPS structure (d3dkmddi.h)

A kernel-mode display driver uses the DXGK_GPUPCAPS structure to identify its GPU capabilities.

Syntax

typedef struct _DXGK_GPUPCAPS {
  union {
    struct {
      UINT VirtualMachineHibernation : 1;
      UINT HotDriverUpdate : 1;
      UINT LiveMigration : 1;
      UINT ScatterMapReserve : 1;
#if ...
      UINT Reserved : 28;
#else
      UINT Reserved : 30;
#endif
    };
    UINT Value;
  } Caps;
} DXGK_GPUPCAPS;

Members

Caps

Caps.VirtualMachineHibernation

The driver sets the cap if guest hibernation is supported for GPU-P devices. The support for guest hibernation is optional and not required for driver certification. A VM, which has hibernation enabled and a GPU-P adapter added, will fail to start, if the driver does not support guest hibernation.

Caps.HotDriverUpdate

The driver sets the cap if hot driver update is supported for GPU-P devices.

Caps.LiveMigration

Caps.ScatterMapReserve

Caps.Reserved

Reserved.

Caps.Value

The UINT collection of bitfields for the different GPU-P capabilities.

Remarks

The KMD must fill out these caps in response to a DXGKQAITYPE_GPUPCAPS QueryAdapterInfo request. The OS queries for these during device initialization after it calls DxgkDdiStartDevice and only if the adapter supports GPU partitioning.
