DXGK_NODEMETADATA_FLAGS structure (d3dkmdt.h)

The DXGK_NODEMETADATA_FLAGS structure describes the capabilities of an engine on a GPU node.

Syntax

typedef struct _DXGK_NODEMETADATA_FLAGS {
  union {
    struct {
      UINT ContextSchedulingSupported : 1;
      UINT RingBufferFenceRelease : 1;
      UINT SupportTrackedWorkload : 1;
      UINT UserModeSubmission : 1;
#if ...
      UINT Reserved : 12;
      UINT MaxInFlightHwQueueBuffers : 16;
#else
      UINT Reserved : 31;
#endif
    };
    UINT32 Value;
  };
} DXGK_NODEMETADATA_FLAGS;

Members

ContextSchedulingSupported

The engine supports the context-based scheduling model.

RingBufferFenceRelease

The engine supports ring buffer fence release. Available starting with Windows 10, version 1809.

SupportTrackedWorkload

The engine supports tracked workloads. Available starting with Windows 10, version 1809.

UserModeSubmission

The engine supports user-mode submission. Available starting with Windows 10, version 1809.

Reserved

Reserved.

MaxInFlightHwQueueBuffers

The maximum number of command buffers submitted by the hardware scheduler to the kernel-mode driver. A value of zero indicates no limit. Available starting with Windows 10, version 1809.

Value

An alternative way to access the structure members.

Requirements

Requirement	Value
Minimum supported client	Windows 10 version 1703
