C Specification

To create pipeline cache objects, call:

// Provided by VK_VERSION_1_0
VkResult vkCreatePipelineCache(
    VkDevice                                    device,
    const VkPipelineCacheCreateInfo*            pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkPipelineCache*                            pPipelineCache);


  • device is the logical device that creates the pipeline cache object.

  • pCreateInfo is a pointer to a VkPipelineCacheCreateInfo structure containing initial parameters for the pipeline cache object.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pPipelineCache is a pointer to a VkPipelineCache handle in which the resulting pipeline cache object is returned.



Applications can track and manage the total host memory size of a pipeline cache object using the pAllocator. Applications can limit the amount of data retrieved from a pipeline cache object in vkGetPipelineCacheData. Implementations should not internally limit the total number of entries added to a pipeline cache object or the total host memory consumed.

Once created, a pipeline cache can be passed to the vkCreateGraphicsPipelines vkCreateRayTracingPipelinesKHR, vkCreateRayTracingPipelinesNV, and vkCreateComputePipelines commands. If the pipeline cache passed into these commands is not VK_NULL_HANDLE, the implementation will query it for possible reuse opportunities and update it with new content. The use of the pipeline cache object in these commands is internally synchronized, and the same pipeline cache object can be used in multiple threads simultaneously.

If flags of pCreateInfo includes VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT, all commands that modify the returned pipeline cache object must be externally synchronized.


Implementations should make every effort to limit any critical sections to the actual accesses to the cache, which is expected to be significantly shorter than the duration of the vkCreate*Pipelines commands.

Valid Usage (Implicit)
  • VUID-vkCreatePipelineCache-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreatePipelineCache-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkPipelineCacheCreateInfo structure

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

  • VUID-vkCreatePipelineCache-pPipelineCache-parameter
    pPipelineCache must be a valid pointer to a VkPipelineCache handle

Return Codes
On success, this command returns

On failure, this command returns
