Create Ready Session A one call to create a ready profiling or tracing session, so that the session will be ready to collect counters with a one call to rocprofiler_start_session.
::rocprofiler_session_set_filter can be used to set optional filters like specific GPUs/Kernel Names/Counter Names and more. The Creation of the session is responsible for the creation of the buffer saving the records generated while the session is active. Session can be started using rocprofiler_start_session and can be stopped using rocprofiler_terminate_session
- Parameters
-
[in] counters counter filter data, it is required from the user to create the filter with ::ROCPROFILER_FILTER_PROFILER_COUNTER_NAMES and to provide an array of counter names needed and their count [in] replay_mode The Replay strategy that should be used if replay is needed [in] filter_kind Filter kind associated with these filters [in] data Pointer to the filter data [in] data_count Filter data array count [in] buffer_size Size of the memory pool that will be used to save the data from profiling or/and tracing, if the buffer was allocated before it will be reallocated with the new size in addition to the old size [in] buffer_callback Asynchronous callback using Memory buffers saving the data and then it will be flushed if the user called rocprofiler_flush_data or if the buffer is full or if the application finished execution [out] session_id Pointer to the created session id, the session is alive up till rocprofiler_destroy_session being called, however, the session id can be used while the session is active which can be activated using rocprofiler_start_session and deactivated using rocprofiler_terminate_session but rocprofiler_flush_data can use session_id even if it is deactivated for flushing the saved records [in] property Filter Property (Optional) [in] callback Synchronous callback for API traces (Optional)
- Return values
-
ROCPROFILER_STATUS_SUCCESS The function has been executed successfully. ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,if rocprofiler_initialize wasn't called before or if rocprofiler_finalize is called ::ROCPROFILER_STATUS_ERROR_SESSION_MODE_FILTER_MISMATCH The session doesn't have the required mode for that filter type ROCPROFILER_STATUS_ERROR_FILTER_DATA_CORRUPTED Data can't be read or corrupted ROCPROFILER_STATUS_ERROR_INCORRECT_SIZE If the size is less than one potential record size
◆ rocprofiler_create_session()

| rocprofiler_session_id_t * | session_id | ||
| ) |
Create Session A ROCProfiler Session is having enough information about what needs to be collected or traced and it allows the user to start/stop profiling/tracing whenever required.
Session will hold multiple mode, that can be added using ::rocprofiler_add_session_mode, it is required to add at least one session mode, if it is tracing or profiling and using ::rocprofiler_session_set_filter can set specific data that is required for the profiler or the tracer such as the counters for profiling or the APIs for tracing before calling rocprofiler_start_session, also ::rocprofiler_session_set_filter can be used to set optional filters like specific GPUs/Kernel Names/API Names and more. Session can be started using rocprofiler_start_session and can be stopped using rocprofiler_terminate_session
- Parameters
-
[in] replay_mode The Replay strategy that should be used if replay is needed [out] session_id Pointer to the created session id, the session is alive up till rocprofiler_destroy_session being called, however, the session id can be used while the session is active which can be activated using rocprofiler_start_session and deactivated using rocprofiler_terminate_session but rocprofiler_flush_data can use session_id even if it is deactivated for flushing the saved records
- Return values
-
ROCPROFILER_STATUS_SUCCESS The function has been executed successfully. ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,if rocprofiler_initialize wasn't called before or if rocprofiler_finalize is called
◆ rocprofiler_destroy_session()
| ROCPROFILER_API rocprofiler_status_t rocprofiler_destroy_session | ( | rocprofiler_session_id_t | session_id | ) |
Destroy Session Destroy session created by rocprofiler_create_session, please refer to the samples for how to use.
This marks the end of session and its own id life and none of the session related functions will be available after this call.
- Parameters
-
[in] session_id The created session id
- Return values
-
ROCPROFILER_STATUS_SUCCESS The function has been executed successfully ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,if rocprofiler_initialize wasn't called before or if rocprofiler_finalize is called ROCPROFILER_STATUS_ERROR_SESSION_NOT_FOUND may return if the session is not found
◆ rocprofiler_start_session()
| ROCPROFILER_API rocprofiler_status_t rocprofiler_start_session | ( | rocprofiler_session_id_t | session_id | ) |
Activate Session Activating session created by rocprofiler_create_session, please refer to the samples for how to use.
- Parameters
-
[in] session_id Session ID representing the created session
- Return values
-
ROCPROFILER_STATUS_SUCCESS The function has been executed successfully ROCPROFILER_STATUS_ERROR_NOT_INITIALIZED,if rocprofiler_initialize wasn't called before or if rocprofiler_finalize is called ROCPROFILER_STATUS_ERROR_SESSION_NOT_FOUND may return if the session is not found ::ROCPROFILER_STATUS_ERROR_SESSION_MODE_NOT_ADDED if there is no session_mode added ::ROCPROFILER_STATUS_ERROR_MISSING_SESSION_CALLBACK if any session_mode is missing callback set ROCPROFILER_STATUS_ERROR_HAS_ACTIVE_SESSION if there is already active session
◆ rocprofiler_terminate_session()
| ROCPROFILER_API rocprofiler_status_t rocprofiler_terminate_session | ( | rocprofiler_session_id_t | session_id | ) |
Deactivate Session Deactivate session created by rocprofiler_create_session, please refer to the samples for how to use.
- Parameters
-
[in] session_id Session ID for the session that will be terminated
- Return values
-
ROCPROFILER_STATUS_SUCCESS The function has been executed successfully ROCPROFILER_STATUS_ERROR_SESSION_NOT_FOUND may return if the session is not found ROCPROFILER_STATUS_ERROR_SESSION_NOT_ACTIVE if the session is not active
