Description
This extension adds a mechanism to provide feedback to an application about pipeline creation, with the specific goal of allowing a feedback loop between build systems and in-the-field application executions to ensure effective pipeline caches are shipped to customers.

Documentation
data PipelineCreationFeedbackEXT Source #
VkPipelineCreationFeedbackEXT - Feedback about the creation of a pipeline or pipeline stage
Description
If the PIPELINE_CREATION_FEEDBACK_VALID_BIT_EXT is not set in flags,
an implementation must not set any other bits in flags, and the
values of all other PipelineCreationFeedbackEXT data members are
undefined.

data PipelineCreationFeedbackCreateInfoEXT Source #
VkPipelineCreationFeedbackCreateInfoEXT - Request for feedback about the creation of a pipeline
Description
An implementation should write pipeline creation feedback to
pPipelineCreationFeedback and may write pipeline stage creation
feedback to pPipelineStageCreationFeedbacks. An implementation must
set or clear the PIPELINE_CREATION_FEEDBACK_VALID_BIT_EXT in
PipelineCreationFeedbackEXT::flags for pPipelineCreationFeedback
and every element of pPipelineStageCreationFeedbacks.
Note
One common scenario for an implementation to skip per-stage feedback is
when PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT_EXT
is set in pPipelineCreationFeedback.
When chained to
RayTracingPipelineCreateInfoKHR,
RayTracingPipelineCreateInfoNV, or
GraphicsPipelineCreateInfo, the i element of
pPipelineStageCreationFeedbacks corresponds to the i element of
RayTracingPipelineCreateInfoKHR::pStages,
RayTracingPipelineCreateInfoNV::pStages,
or GraphicsPipelineCreateInfo::pStages. When
chained to ComputePipelineCreateInfo, the first
element of pPipelineStageCreationFeedbacks corresponds to
ComputePipelineCreateInfo::stage.
Valid Usage
-
When chained to
GraphicsPipelineCreateInfo,PipelineCreationFeedbackEXT::pipelineStageCreationFeedbackCountmust equalGraphicsPipelineCreateInfo::stageCount
-
When chained to
ComputePipelineCreateInfo,PipelineCreationFeedbackEXT::pipelineStageCreationFeedbackCountmust equal 1 -
When chained to
RayTracingPipelineCreateInfoKHR,PipelineCreationFeedbackEXT::pipelineStageCreationFeedbackCountmust equalRayTracingPipelineCreateInfoKHR::stageCount -
When chained to
RayTracingPipelineCreateInfoNV,PipelineCreationFeedbackEXT::pipelineStageCreationFeedbackCountmust equalRayTracingPipelineCreateInfoNV::stageCount
Valid Usage (Implicit)
-
pPipelineCreationFeedbackmust be a valid pointer to aPipelineCreationFeedbackEXTstructure -
pPipelineStageCreationFeedbacksmust be a valid pointer to an array ofpipelineStageCreationFeedbackCountPipelineCreationFeedbackEXTstructures -
pipelineStageCreationFeedbackCountmust be greater than0

| pattern PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT_EXT :: PipelineCreationFeedbackFlagBitsEXT |
An implementation should set the
Note Implementations are encouraged to provide a meaningful signal to applications using this bit. The intention is to communicate to the application that the pipeline or pipeline stage was created "as fast as it gets" using the pipeline cache provided by the application. If an implementation uses an internal cache, it is discouraged from setting this bit as the feedback would be unactionable. |

An implementation should set the
Note While "significant amount of work" is subjective, implementations are encouraged to provide a meaningful signal to applications using this bit. For example, a 1% reduction in duration may not warrant setting this bit, while a 50% reduction would. |
