To query the number of passes required to query a performance query pool on a physical device, call:
// Provided by VK_KHR_performance_query void vkGetPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR( VkPhysicalDevice physicalDevice, const VkQueryPoolPerformanceCreateInfoKHR* pPerformanceQueryCreateInfo, uint32_t* pNumPasses);
physicalDeviceis the handle to the physical device whose queue family performance query counter properties will be queried.
pPerformanceQueryCreateInfois a pointer to a
VkQueryPoolPerformanceCreateInfoKHRof the performance query that is to be created.
pNumPassesis a pointer to an integer related to the number of passes required to query the performance query pool, as described below.
queueFamilyIndex must be a
queue family of
The number of passes required to capture the counters specified in the
pCounters is returned in
