D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAGS enumeration (d3d12sdklayers.h)

Specifies how GPU-Based Validation handles patched pipeline states during ID3D12Device::CreateGraphicsPipelineState and ID3D12Device::CreateComputePipelineState.

Syntax

typedef enum D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAGS {
  D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_NONE = 0,
  D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_TRACKING_ONLY_SHADERS = 0x1,
  D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_UNGUARDED_VALIDATION_SHADERS = 0x2,
  D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_GUARDED_VALIDATION_SHADERS = 0x4,
  D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAGS_VALID_MASK = 0x7
} ;

Constants

D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_NONE Value: 0 This is the default value. Indicates no patching of pipeline states should be done during PSO creation. Instead PSO’s are patched on first use in a command list. This can help to reduce the up-front cost of PSO creation but may instead slow down command list recording until a steady-state is reached.
D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_TRACKING_ONLY_SHADERS Value: 0x1 Indicates that state-tracking GPU-Based Validation PSO’s should be created along with the original PSO at create time.
D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_UNGUARDED_VALIDATION_SHADERS Value: 0x2 Indicates that unguarded GPU-Based Validation PSO’s should be created along with the original PSO at create time.
D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAG_FRONT_LOAD_CREATE_GUARDED_VALIDATION_SHADERS Value: 0x4 Indicates that guarded GPU-Based Validation PSO’s should be created along with the original PSO at create time.
D3D12_GPU_BASED_VALIDATION_PIPELINE_STATE_CREATE_FLAGS_VALID_MASK Value: 0x7 Internal use only.

Remarks

This enum is used by the D3D12_DEBUG_DEVICE_GPU_BASED_VALIDATION_SETTINGS structure.

Generally speaking most application developers are likely to leave this parameter unchanged. However, if the overhead of deferring patched PSO creation is suspected to be too much of a performance problem, then developers should consider changing this setting.
