vkCreateExecutionGraphPipelinesAMDX(3)

C Specification

To create execution graph pipelines, call:

// Provided by VK_AMDX_shader_enqueue
VkResult vkCreateExecutionGraphPipelinesAMDX(
    VkDevice                                    device,
    VkPipelineCache                             pipelineCache,
    uint32_t                                    createInfoCount,
    const VkExecutionGraphPipelineCreateInfoAMDX* pCreateInfos,
    const VkAllocationCallbacks*                pAllocator,
    VkPipeline*                                 pPipelines);

Parameters

device is the logical device that creates the execution graph pipelines.
pipelineCache is either VK_NULL_HANDLE, indicating that pipeline caching is disabled; or the handle of a valid pipeline cache object, in which case use of that cache is enabled for the duration of the command. The implementation must not access this object outside of the duration of this command.
createInfoCount is the length of the pCreateInfos and pPipelines arrays.
pCreateInfos is a pointer to an array of VkExecutionGraphPipelineCreateInfoAMDX structures.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.
pPipelines is a pointer to an array of VkPipeline handles in which the resulting execution graph pipeline objects are returned.

Description

Pipelines are created and returned as described for Multiple Pipeline Creation.

Valid Usage

VUID-vkCreateExecutionGraphPipelinesAMDX-shaderEnqueue-09124
The shaderEnqueue feature must be enabled
VUID-vkCreateExecutionGraphPipelinesAMDX-flags-09125
If the flags member of any element of pCreateInfos contains the VK_PIPELINE_CREATE_DERIVATIVE_BIT flag, and the basePipelineIndex member of that same element is not -1, basePipelineIndex must be less than the index into pCreateInfos that corresponds to that element
VUID-vkCreateExecutionGraphPipelinesAMDX-flags-09126
If the flags member of any element of pCreateInfos contains the VK_PIPELINE_CREATE_DERIVATIVE_BIT flag, the base pipeline must have been created with the VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT flag set
VUID-vkCreateExecutionGraphPipelinesAMDX-pipelineCache-09127
If pipelineCache was created with VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT, host access to pipelineCache must be externally synchronized

VUID-vkCreateExecutionGraphPipelinesAMDX-pNext-09616
If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, pipelineCache must be VK_NULL_HANDLE
VUID-vkCreateExecutionGraphPipelinesAMDX-pNext-09617
If a VkPipelineCreateFlags2CreateInfoKHR structure with the VK_PIPELINE_CREATE_2_CAPTURE_DATA_BIT_KHR flag set is included in the pNext chain of any element of pCreateInfos, pipelineCache must be VK_NULL_HANDLE
VUID-vkCreateExecutionGraphPipelinesAMDX-binaryCount-09620
If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT must not be set in the flags of that element
VUID-vkCreateExecutionGraphPipelinesAMDX-binaryCount-09621
If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATION_FEEDBACK_BASE_PIPELINE_ACCELERATION_BIT must not be set in the flags of that element
VUID-vkCreateExecutionGraphPipelinesAMDX-binaryCount-09622
If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT_EXT must not be set in the flags of that element
VUID-vkCreateExecutionGraphPipelinesAMDX-pCreateInfos-11414
If any element of pCreateInfos sets VK_PIPELINE_CREATE_2_DESCRIPTOR_HEAP_BIT_EXT and includes embedded sampler mappings, there must be less than (maxSamplerAllocationCount - (minSamplerHeapReservedRangeWithEmbedded / samplerDescriptorSize)) VkSampler objects currently created on the device
VUID-vkCreateExecutionGraphPipelinesAMDX-pCreateInfos-11429
If any element of pCreateInfos sets VK_PIPELINE_CREATE_2_DESCRIPTOR_HEAP_BIT_EXT and includes embedded sampler mappings, this command must not cause the total number of unique embedded samplers in pipelines and shaders on this device to exceed maxDescriptorHeapEmbeddedSamplers

Valid Usage (Implicit)

VUID-vkCreateExecutionGraphPipelinesAMDX-device-parameter
device must be a valid VkDevice handle
VUID-vkCreateExecutionGraphPipelinesAMDX-pipelineCache-parameter
If pipelineCache is not VK_NULL_HANDLE, pipelineCache must be a valid VkPipelineCache handle
VUID-vkCreateExecutionGraphPipelinesAMDX-pCreateInfos-parameter
pCreateInfos must be a valid pointer to an array of createInfoCount valid VkExecutionGraphPipelineCreateInfoAMDX structures
VUID-vkCreateExecutionGraphPipelinesAMDX-pAllocator-parameter
If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure
VUID-vkCreateExecutionGraphPipelinesAMDX-pPipelines-parameter
pPipelines must be a valid pointer to an array of createInfoCount VkPipeline handles
VUID-vkCreateExecutionGraphPipelinesAMDX-createInfoCount-arraylength
createInfoCount must be greater than 0
VUID-vkCreateExecutionGraphPipelinesAMDX-pipelineCache-parent
If pipelineCache is a valid handle, it must have been created, allocated, or retrieved from device

On success, this command returns

On failure, this command returns
