C Specification

To create compute pipelines, call:

// Provided by VK_VERSION_1_0
VkResult vkCreateComputePipelines(
    VkDevice                                    device,
    VkPipelineCache                             pipelineCache,
    uint32_t                                    createInfoCount,
    const VkComputePipelineCreateInfo*          pCreateInfos,
    const VkAllocationCallbacks*                pAllocator,
    VkPipeline*                                 pPipelines);

Parameters

  • device is the logical device that creates the compute 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.

  • createInfoCount is the length of the pCreateInfos and pPipelines arrays.

  • pCreateInfos is a pointer to an array of VkComputePipelineCreateInfo 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 compute pipeline objects are returned.

Description

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

Valid Usage

  • VUID-vkCreateComputePipelines-flags-00695
    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-vkCreateComputePipelines-flags-00696
    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-vkCreateComputePipelines-pipelineCache-02873
    If pipelineCache was created with VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT, host access to pipelineCache must be externally synchronized

Valid Usage (Implicit)

  • VUID-vkCreateComputePipelines-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreateComputePipelines-pipelineCache-parameter
    If pipelineCache is not VK_NULL_HANDLE, pipelineCache must be a valid VkPipelineCache handle

  • VUID-vkCreateComputePipelines-pCreateInfos-parameter
    pCreateInfos must be a valid pointer to an array of createInfoCount valid VkComputePipelineCreateInfo structures

  • VUID-vkCreateComputePipelines-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkCreateComputePipelines-pPipelines-parameter
    pPipelines must be a valid pointer to an array of createInfoCount VkPipeline handles

  • VUID-vkCreateComputePipelines-createInfoCount-arraylength
    createInfoCount must be greater than 0

  • VUID-vkCreateComputePipelines-pipelineCache-parent
    If pipelineCache is a valid handle, it must have been created, allocated, or retrieved from device

Return Codes
On success, this command returns

  • VK_SUCCESS

  • VK_PIPELINE_COMPILE_REQUIRED_EXT

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_INVALID_SHADER_NV
