-> QueryResultFlags

flags is a bitmask of QueryResultFlagBits specifying how and when results are returned.

-> io Result

vkGetQueryPoolResults - Copy results of queries in a query pool to a host memory region

Description

The range of queries read is defined by [firstQuery, firstQuery + queryCount - 1]. For pipeline statistics queries, each query index in the pool contains one integer value for each bit that is enabled in QueryPoolCreateInfo::pipelineStatistics when the pool is created.

If no bits are set in flags, and all requested queries are in the available state, results are written as an array of 32-bit unsigned integer values. The behavior when not all queries are available, is described below.

If QUERY_RESULT_64_BIT is not set and the result overflows a 32-bit value, the value may either wrap or saturate. Similarly, if QUERY_RESULT_64_BIT is set and the result overflows a 64-bit value, the value may either wrap or saturate.

If QUERY_RESULT_WAIT_BIT is set, Vulkan will wait for each query to be in the available state before retrieving the numerical results for that query. In this case, getQueryPoolResults is guaranteed to succeed and return SUCCESS if the queries become available in a finite time (i.e. if they have been issued and not reset). If queries will never finish (e.g. due to being reset but not issued), then getQueryPoolResults may not return in finite time.

If QUERY_RESULT_WAIT_BIT and QUERY_RESULT_PARTIAL_BIT are both not set then no result values are written to pData for queries that are in the unavailable state at the time of the call, and getQueryPoolResults returns NOT_READY. However, availability state is still written to pData for those queries if QUERY_RESULT_WITH_AVAILABILITY_BIT is set.

Note

Applications must take care to ensure that use of the QUERY_RESULT_WAIT_BIT bit has the desired effect.

For example, if a query has been used previously and a command buffer records the commands cmdResetQueryPool, cmdBeginQuery, and cmdEndQuery for that query, then the query will remain in the available state until resetQueryPool is called or the cmdResetQueryPool command executes on a queue. Applications can use fences or events to ensure that a query has already been reset before checking for its results or availability status. Otherwise, a stale value could be returned from a previous use of the query.

The above also applies when QUERY_RESULT_WAIT_BIT is used in combination with QUERY_RESULT_WITH_AVAILABILITY_BIT. In this case, the returned availability status may reflect the result of a previous use of the query unless resetQueryPool is called or the cmdResetQueryPool command has been executed since the last use of the query.

Note

Applications can double-buffer query pool usage, with a pool per frame, and reset queries at the end of the frame in which they are read.

If QUERY_RESULT_PARTIAL_BIT is set, QUERY_RESULT_WAIT_BIT is not set, and the query’s status is unavailable, an intermediate result value between zero and the final result value is written to pData for that query.

If QUERY_RESULT_WITH_AVAILABILITY_BIT is set, the final integer value written for each query is non-zero if the query’s status was available or zero if the status was unavailable. When QUERY_RESULT_WITH_AVAILABILITY_BIT is used, implementations must guarantee that if they return a non-zero availability value then the numerical results must be valid, assuming the results are not reset by a subsequent command.

Note

Satisfying this guarantee may require careful ordering by the application, e.g. to read the availability status before reading the results.

Valid Usage

• firstQuery must be less than the number of queries in queryPool

• If QUERY_RESULT_64_BIT is not set in flags, then pData and stride must be multiples of 4
• If QUERY_RESULT_64_BIT is not set in flags and the queryType used to create queryPool was not QUERY_TYPE_PERFORMANCE_QUERY_KHR, then pData and stride must be multiples of 4
• If QUERY_RESULT_64_BIT is set in flags then pData and stride must be multiples of 8
• If the queryType used to create queryPool was QUERY_TYPE_PERFORMANCE_QUERY_KHR, then pData and stride must be multiples of the size of PerformanceCounterResultKHR
• If the queryType used to create queryPool was QUERY_TYPE_PERFORMANCE_QUERY_KHR, then stride must be large enough to contain QueryPoolPerformanceCreateInfoKHR::counterIndexCount used to create queryPool times the size of PerformanceCounterResultKHR.
• The sum of firstQuery and queryCount must be less than or equal to the number of queries in queryPool
• dataSize must be large enough to contain the result of each query, as described here
• If the queryType used to create queryPool was QUERY_TYPE_TIMESTAMP, flags must not contain QUERY_RESULT_PARTIAL_BIT
• If the queryType used to create queryPool was QUERY_TYPE_PERFORMANCE_QUERY_KHR, flags must not contain QUERY_RESULT_WITH_AVAILABILITY_BIT, QUERY_RESULT_PARTIAL_BIT or QUERY_RESULT_64_BIT
• If the queryType used to create queryPool was QUERY_TYPE_PERFORMANCE_QUERY_KHR, the queryPool must have been recorded once for each pass as retrieved via a call to getPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR

Valid Usage (Implicit)

• device must be a valid Device handle

• queryPool must be a valid QueryPool handle
• pData must be a valid pointer to an array of dataSize bytes
• flags must be a valid combination of QueryResultFlagBits values
• dataSize must be greater than 0

newtype QueryPipelineStatisticFlagBits

VkQueryPipelineStatisticFlagBits - Bitmask specifying queried pipeline statistics

Description

These values are intended to measure relative statistics on one implementation. Various device architectures will count these values differently. Any or all counters may be affected by the issues described in Query Operation.

Note

For example, tile-based rendering devices may need to replay the scene multiple times, affecting some of the counts.

If a pipeline has rasterizerDiscardEnable enabled, implementations may discard primitives after the final vertex processing stage. As a result, if rasterizerDiscardEnable is enabled, the clipping input and output primitives counters may not be incremented.

When a pipeline statistics query finishes, the result for that query is marked as available. The application can copy the result to a buffer (via cmdCopyQueryPoolResults), or request it be put into host memory (via getQueryPoolResults).

QUERY_PIPELINE_STATISTIC_CLIPPING_PRIMITIVES_BIT specifies that queries managed by the pool will count the number of primitives output by the Primitive Clipping stage of the pipeline. The counter’s value is incremented each time a primitive passes the primitive clipping stage. The actual number of primitives output by the primitive clipping stage for a particular input primitive is implementation-dependent but must satisfy the following conditions:

The counter’s value is incremented every time the compute shader is invoked. Implementations may skip the execution of certain compute shader invocations or execute additional compute shader invocations for implementation-dependent reasons as long as the results of rendering otherwise remain unchanged.
