C Specification

The VkQueryPoolCreateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkQueryPoolCreateInfo {
    VkStructureType                  sType;
    const void*                      pNext;
    VkQueryPoolCreateFlags           flags;
    VkQueryType                      queryType;
    uint32_t                         queryCount;
    VkQueryPipelineStatisticFlags    pipelineStatistics;
} VkQueryPoolCreateInfo;



pipelineStatistics is ignored if queryType is not VK_QUERY_TYPE_PIPELINE_STATISTICS.

Valid Usage
  • VUID-VkQueryPoolCreateInfo-queryType-00791
    If the pipeline statistics queries feature is not enabled, queryType must not be VK_QUERY_TYPE_PIPELINE_STATISTICS

  • VUID-VkQueryPoolCreateInfo-queryType-00792
    If queryType is VK_QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must be a valid combination of VkQueryPipelineStatisticFlagBits values

  • VUID-VkQueryPoolCreateInfo-queryType-03222
    If queryType is VK_QUERY_TYPE_PERFORMANCE_QUERY_KHR, the pNext chain must include a VkQueryPoolPerformanceCreateInfoKHR structure

  • VUID-VkQueryPoolCreateInfo-queryCount-02763
    queryCount must be greater than 0

Valid Usage (Implicit)
  • VUID-VkQueryPoolCreateInfo-sType-sType

  • VUID-VkQueryPoolCreateInfo-pNext-pNext
    Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkQueryPoolPerformanceCreateInfoKHR, VkQueryPoolPerformanceQueryCreateInfoINTEL, or VkVideoProfileKHR

  • VUID-VkQueryPoolCreateInfo-sType-unique
    The sType value of each struct in the pNext chain must be unique

  • VUID-VkQueryPoolCreateInfo-flags-zerobitmask
    flags must be 0

  • VUID-VkQueryPoolCreateInfo-queryType-parameter
    queryType must be a valid VkQueryType value
