/** \section rocprofiler_plugin_api ROCMTools Plugin API
|
|
*
|
|
* The ROCMTools Plugin API is used by the ROCMTools Tool to output all
|
|
* profiling information. Different implementations of the ROCMTools Plugin
|
|
* API can be developed that output the data in different formats. The
|
|
* ROCMTools Tool can be configured to load a specific library that supports
|
|
* the user desired format.
|
|
*
|
|
* The API is not thread safe. It is the responsibility of the ROCMTools Tool
|
|
* to ensure the operations are synchronized and not called concurrently. There
|
|
* is no requirement for the ROCMTools Tool to report trace data in any
|
|
* specific order. If the format supported by plugin requires specific
|
|
* ordering, it is the responsibility of the plugin implementation to perform
|
|
* any necessary sorting.
