public class KHRPerformanceQuery
extends java.lang.Object
VK_KHR_performance_query extension adds a mechanism to allow querying of performance counters for use in applications and by profiling tools.
Each queue family may expose counters that can be enabled on a queue of that family. We extend VkQueryType to add a new query type for performance queries, and chain a structure on VkQueryPoolCreateInfo to specify the performance queries to enable.
The following example shows how to find what performance counters a queue family supports, setup a query pool to record these performance counters, how to add the query pool to the command buffer to record information, and how to get the results from the query pool.
// A previously created physical device
VkPhysicalDevice physicalDevice;
// One of the queue families our device supports
uint32_t queueFamilyIndex;
uint32_t counterCount;
// Get the count of counters supported

// Try to enable the first 8 counters
uint32_t enabledCounters[8];
const uint32_t enabledCounterCount = min(counterCount, 8));

enabledCounters[i] = i;

To enumerate the performance query counters available on a queue family of a physical device, call:
VkResult vkEnumeratePhysicalDeviceQueueFamilyPerformanceQueryCountersKHR(
VkPhysicalDevice physicalDevice,
uint32_t queueFamilyIndex,
uint32_t* pCounterCount,
VkPerformanceCounterKHR* pCounters,
VkPerformanceCounterDescriptionKHR* pCounterDescriptions);If pCounters is NULL and pCounterDescriptions is NULL, then the number of counters available is returned in pCounterCount. Otherwise, pCounterCount must point to a variable set by the user to the number of elements in the pCounters, pCounterDescriptions, or both arrays and on return the variable is overwritten with the number of structures actually written out. If pCounterCount is less than the number of counters available, at most pCounterCount structures will be written and INCOMPLETE will be returned instead of SUCCESS.

To record and submit a command buffer that contains a performance query pool the profiling lock must be held. The profiling lock must be acquired prior to any call to BeginCommandBuffer that will be using a performance query pool. The profiling lock must be held while any command buffer that contains a performance query pool is in the recording, executable, or pending state. To acquire the profiling lock, call:
VkResult vkAcquireProfilingLockKHR(
VkDevice device,
const VkAcquireProfilingLockInfoKHR* pInfo);Implementations may allow multiple actors to hold the profiling lock concurrently.
