=======================
|
||
|
|
|
||
|
|
Name
|
||
|
|
----
|
||
|
|
vkCmdWriteTimestamp - Write a device timestamp into a query object.
|
||
|
|
|
||
|
|
C Specification
|
||
|
|
---------------
|
||
|
|
|
||
|
|
include::../protos/vkCmdWriteTimestamp.txt[]
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
|
||
|
|
pname:commandBuffer::
|
||
|
|
The command buffer into which the command will be placed.
|
||
|
|
|
||
|
|
pname:pipelineStage::
|
||
|
|
The stage of the pipeline at which the timestamp will be written.
|
||
|
|
|
||
|
|
pname:queryPool::
|
||
|
|
A handle to the query pool object containing the query.
|
||
|
|
|
||
|
|
pname:entry::
|
||
|
|
The entry in the query pool at which to write the query.
|
||
|
|
|
||
|
|
Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
fname:vkCmdWriteTimestamp places a command into the command buffer specified
|
||
|
|
by pname:commandBuffer which, when executed, will cause the GPU to write its
|
||
|
|
internal timestamp into the query pool specified by pname:queryPool at the
|
||
|
|
entry specified in pname:entry. The timestamp is written when the command
|
||
|
|
passes the pipeline stage specified by pname:pipelineStage. The pipeline
|
||
|
|
stage is a single member of the elink:VkPipelineStageFlagBits enumeration,
|
||
|
|
the definition of which is:
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
If an implementation is not capable of writing a timestamp value at the
|
||
|
|
pipeline point specified, it may at its option write the timestamp at
|
||
|
|
any point appearing later in the logical pipeline. However, it must do
|
||
|
|
this consistently for similar pipeline configurations.
