DXGK_NODEMETADATA_FLAGS structure

Description

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

Members

`ContextSchedulingSupported`

The engine supports the context-based scheduling model.

`RingBufferFenceRelease`

The engine supports ring buffer fence release. Supported 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 work submission. Supported starting with Windows 11, version 24H2.

`SupportBuildTestCommandBuffer`

The engine supports kernel-mode testing. Supported starting with Windows 11, version 24H2.

`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.

`Reserved`

Reserved.

`Value`
