Structure specifying parameters of a newly created query pool.

Description

pipelineStatistics is ignored if queryType is not QUERY_TYPE_PIPELINE_STATISTICS.

Valid Usage

• If the pipelineStatisticsQuery feature is not enabled, queryType must not be QUERY_TYPE_PIPELINE_STATISTICS
• If the meshShaderQueries feature is not enabled, queryType must not be QUERY_TYPE_MESH_PRIMITIVES_GENERATED_EXT
• If the meshShaderQueries feature is not enabled, and queryType is QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must not contain QUERY_PIPELINE_STATISTIC_TASK_SHADER_INVOCATIONS_BIT_EXT or QUERY_PIPELINE_STATISTIC_MESH_SHADER_INVOCATIONS_BIT_EXT
• If queryType is QUERY_TYPE_PIPELINE_STATISTICS, pipelineStatistics must be a valid combination of VkQueryPipelineStatisticFlagBits values
• If queryType is QUERY_TYPE_PERFORMANCE_QUERY_KHR, the pNext chain must include a VkQueryPoolPerformanceCreateInfoKHR structure
• queryCount must be greater than 0
• If queryType is QUERY_TYPE_VIDEO_ENCODE_FEEDBACK_KHR, then the pNext chain must include a VkVideoProfileInfoKHR structure with videoCodecOperation specifying an encode operation
• If queryType is QUERY_TYPE_VIDEO_ENCODE_FEEDBACK_KHR, then the pNext chain must include a VkQueryPoolVideoEncodeFeedbackCreateInfoKHR structure
• If queryType is 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 GetPhysicalDeviceVideoCapabilitiesKHR for the video profile described by VkVideoProfileInfoKHR and its pNext chain

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO
• 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
• The sType value of each struct in the pNext chain must be unique
• flags must be 0
• queryType must be a valid VkQueryType value
