Kernel Dispatch Callback. This is a callback that is invoked before the kernel is enqueued into the HSA queue. What counters to collect for a kernel are set via passing back a profile config (config) in this callback. These counters will be collected and emplaced in the buffer with rocprofiler_buffer_id_t used when setting up this callback. | |

Counting record callback. This is a callback is invoked when the kernel execution is complete and contains the counter profile data requested in rocprofiler_dispatch_counting_service_callback_t. Only used with rocprofiler_configure_callback_dispatch_counting_service. | |

Configure buffered dispatch profile Counting Service. Collects the counters in dispatch packets and stores them in a buffer with buffer_id . The buffer may contain packets from more than one dispatch (denoted by correlation id). Will trigger the callback based on the parameters setup in buffer_id_t. | |

Function Documentation
◆ rocprofiler_configure_buffered_dispatch_counting_service()
rocprofiler_status_t rocprofiler_configure_buffered_dispatch_counting_service | ( | rocprofiler_context_id_t | context_id, |
rocprofiler_buffer_id_t | buffer_id, | ||
rocprofiler_dispatch_counting_service_callback_t | callback, | ||
void * | callback_data_args | ||
) |
Configure buffered dispatch profile Counting Service. Collects the counters in dispatch packets and stores them in a buffer with buffer_id
. The buffer may contain packets from more than one dispatch (denoted by correlation id). Will trigger the callback based on the parameters setup in buffer_id_t.
NOTE: Interface is up for comment as to whether restrictions on agent should be made here (limiting the CB based on agent) or if the restriction should be performed by the tool in rocprofiler_dispatch_counting_service_callback_t (i.e. tool code checking the agent param to see if they want to profile it).

- Parameters
-
[in] context_id context id [in] buffer_id id of the buffer to use for the counting service [in] callback callback to perform when dispatch is enqueued [in] callback_data_args callback data
- Returns
- rocprofiler_status_t
