VkQueryPoolCreateInfo(3)

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;

Members

sType is the type of this structure.
pNext is NULL or a pointer to a structure extending this structure.
flags is reserved for future use.
queryType is a VkQueryType value specifying the type of queries managed by the pool.
queryCount is the number of queries managed by the pool.
pipelineStatistics is a bitmask of VkQueryPipelineStatisticFlagBits specifying which counters will be returned in queries on the new pool, as described below in https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#queries-pipestats.

Description

pipelineStatistics is ignored if queryType is not VK_QUERY_TYPE_PIPELINE_STATISTICS.

Valid Usage

VUID-VkQueryPoolCreateInfo-queryType-00791
If the pipelineStatisticsQuery feature is not enabled, queryType must not be VK_QUERY_TYPE_PIPELINE_STATISTICS
VUID-VkQueryPoolCreateInfo-meshShaderQueries-07068
If the meshShaderQueries feature is not enabled, queryType must not be VK_QUERY_TYPE_MESH_PRIMITIVES_GENERATED_EXT
VUID-VkQueryPoolCreateInfo-meshShaderQueries-07069
If the meshShaderQueries feature is not enabled, and queryType is VK_QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must not contain VK_QUERY_PIPELINE_STATISTIC_TASK_SHADER_INVOCATIONS_BIT_EXT or VK_QUERY_PIPELINE_STATISTIC_MESH_SHADER_INVOCATIONS_BIT_EXT
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
VUID-VkQueryPoolCreateInfo-queryType-07133
If queryType is VK_QUERY_TYPE_VIDEO_ENCODE_FEEDBACK_KHR, then the pNext chain must include a VkVideoProfileInfoKHR structure with videoCodecOperation specifying an encode operation
VUID-VkQueryPoolCreateInfo-queryType-07906
If queryType is VK_QUERY_TYPE_VIDEO_ENCODE_FEEDBACK_KHR, then the pNext chain must include a VkQueryPoolVideoEncodeFeedbackCreateInfoKHR structure
VUID-VkQueryPoolCreateInfo-queryType-07907
If queryType is VK_QUERY_TYPE_VIDEO_ENCODE_FEEDBACK_KHR, and the pNext chain includes a VkVideoProfileInfoKHR structure and a VkQueryPoolVideoEncodeFeedbackCreateInfoKHR structure, then VkQueryPoolVideoEncodeFeedbackCreateInfoKHR::encodeFeedbackFlags must not contain any bits that are not set in VkVideoEncodeCapabilitiesKHR::supportedEncodeFeedbackFlags, as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR for the video profile described by VkVideoProfileInfoKHR and its pNext chain

Valid Usage (Implicit)

VUID-VkQueryPoolCreateInfo-sType-sType
sType must be VK_STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO
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, VkQueryPoolVideoEncodeFeedbackCreateInfoKHR, VkVideoDecodeH264ProfileInfoKHR, VkVideoDecodeH265ProfileInfoKHR, VkVideoDecodeUsageInfoKHR, VkVideoEncodeH264ProfileInfoEXT, VkVideoEncodeH265ProfileInfoEXT, VkVideoEncodeUsageInfoKHR, or VkVideoProfileInfoKHR
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
