Detailed Description

Operations related to AMD GPU workgroups.

Macro Definition Documentation

◆ AMD_DBGAPI_WORKGROUP_NONE

#define AMD_DBGAPI_WORKGROUP_NONE AMD_DBGAPI_HANDLE_LITERAL (amd_dbgapi_workgroup_id_t, 0)

The NULL workgroup handle.

Enumeration Type Documentation

◆ amd_dbgapi_workgroup_info_t

enum amd_dbgapi_workgroup_info_t

Workgroup queries that are supported by amd_dbgapi_workgroup_get_info.

Each query specifies the type of data returned in the value argument to amd_dbgapi_workgroup_get_info.

Enumerator
AMD_DBGAPI_WORKGROUP_INFO_DISPATCH	Return the dispatch to which this workgroup belongs. The type of this attribute is amd_dbgapi_dispatch_id_t. If the dispatch associated with a workgroup is not available then amd_dbgapi_workgroup_get_info returns the AMD_DBGAPI_STATUS_ERROR_NOT_AVAILABLE error. See the Known Limitations and Restrictions section.
AMD_DBGAPI_WORKGROUP_INFO_QUEUE	Return the queue to which this workgroup belongs. The type of this attribute is amd_dbgapi_queue_id_t.
AMD_DBGAPI_WORKGROUP_INFO_AGENT	Return the agent to which this workgroup belongs. The type of this attribute is amd_dbgapi_agent_id_t.
AMD_DBGAPI_WORKGROUP_INFO_PROCESS	Return the process to which this workgroup belongs. The type of this attribute is amd_dbgapi_process_id_t.
AMD_DBGAPI_WORKGROUP_INFO_ARCHITECTURE	Return the architecture of this workgroup. The type of this attribute is amd_dbgapi_architecture_id_t.
AMD_DBGAPI_WORKGROUP_INFO_WORKGROUP_COORD	The workgroup workgroup coordinate in the dispatch grid dimensions. The type of this attribute is `uint32_t`[3] with elements 1, 2, and 3 corresponding to the X, Y, and Z coordinates respectively. If the dispatch associated with a workgroup is not available then amd_dbgapi_workgroup_get_info returns AMD_DBGAPI_STATUS_ERROR_NOT_AVAILABLE. See the Known Limitations and Restrictions section.

Function Documentation

◆ amd_dbgapi_process_workgroup_list()

amd_dbgapi_status_t AMD_DBGAPI amd_dbgapi_process_workgroup_list	(	amd_dbgapi_process_id_t	process_id,
		size_t *	workgroup_count,
		amd_dbgapi_workgroup_id_t **	workgroups,
		amd_dbgapi_changed_t *	changed
	)

Return the list of existing workgroups.

The order of the workgroup handles in the list is unspecified and can vary between calls.

Parameters

[in]	process_id	If AMD_DBGAPI_PROCESS_NONE then the workgroup list for all processes is requested. Otherwise, the workgroup list of process `process_id` is requested.
[out]	workgroup_count	The number of workgroups executing in the process.
[out]	workgroups	If `changed` is not NULL and the workgroup list of all of the processes requested have not changed since the last call(s) to amd_dbgapi_process_workgroup_list for each of them, then return NULL. Otherwise, return a pointer to an array of amd_dbgapi_workgroup_id_t with `workgroup_count` elements. It is allocated by the amd_dbgapi_callbacks_s::allocate_memory callback and is owned by the client.
[in,out]	changed	If NULL then left unaltered. If non-NULL, set to AMD_DBGAPI_CHANGED_NO if the list of workgroups for each requested process is the same as when amd_dbgapi_process_workgroup_list was last called for them. Otherwise, set to AMD_DBGAPI_CHANGED_YES.

Return values

AMD_DBGAPI_STATUS_SUCCESS	The function has been executed successfully and the result is stored in `changed`, `workgroup_count`, and `workgroups`.
AMD_DBGAPI_STATUS_FATAL	A fatal error occurred. The library is left uninitialized; and `changed`, `workgroup_count`, and `workgroups` are unaltered.
AMD_DBGAPI_STATUS_ERROR_NOT_INITIALIZED	The library is not initialized. The library is left uninitialized; and `workgroup_count`, `workgroups`, and `changed` are unaltered.
AMD_DBGAPI_STATUS_ERROR_INVALID_PROCESS_ID	`process_id` is invalid. `workgroup_count`, `workgroups`, and `unchanged` are unaltered.
AMD_DBGAPI_STATUS_ERROR_INVALID_ARGUMENT	`workgroup_count` or `workgroups` are NULL, or `changed` is invalid. `workgroup_count`, `workgroups`, and `changed` are unaltered.
AMD_DBGAPI_STATUS_ERROR_CLIENT_CALLBACK	This will be reported if the amd_dbgapi_callbacks_s::allocate_memory callback used to allocate `workgroups` returns NULL. `workgroup_count`, `workgroups`, and `changed` are unaltered.

◆ amd_dbgapi_workgroup_get_info()

amd_dbgapi_status_t AMD_DBGAPI amd_dbgapi_workgroup_get_info	(	amd_dbgapi_workgroup_id_t	workgroup_id,
		amd_dbgapi_workgroup_info_t	query,
		size_t	value_size,
		void *	value
	)

Query information about a workgroup.

amd_dbgapi_workgroup_info_t specifies the queries supported and the type returned using the value argument.
