AMD SMI: GPU Monitoring

Functions
amdsmi_status_t	amdsmi_get_gpu_activity (amdsmi_device_handle device_handle, amdsmi_engine_usage_t *info)
	Returns the current usage of the GPU engines (GFX, MM and MEM). Each usage is reported as a percentage from 0-100%. More...

amdsmi_status_t	amdsmi_get_power_measure (amdsmi_device_handle device_handle, amdsmi_power_measure_t *info)
	Returns the current power and voltage of the GPU. The voltage is in units of mV and the power in units of W. More...

amdsmi_status_t	amdsmi_get_clock_measure (amdsmi_device_handle device_handle, amdsmi_clk_type_t clk_type, amdsmi_clk_measure_t *info)
	Returns the measurements of the clocks in the GPU for the GFX and multimedia engines and Memory. This call reports the averages over 1s in MHz. More...

amdsmi_status_t	amdsmi_get_vram_usage (amdsmi_device_handle device_handle, amdsmi_vram_info_t *info)
	Returns the VRAM usage (both total and used memory) in MegaBytes. More...

amdsmi_status_t amdsmi_get_gpu_activity	(	amdsmi_device_handle	device_handle,
		amdsmi_engine_usage_t *	info
	)

Returns the current usage of the GPU engines (GFX, MM and MEM). Each usage is reported as a percentage from 0-100%.

Parameters

[in]	device_handle	Device which to query
[out]	info	Reference to the gpu engine usage structure. Must be allocated by user.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

amdsmi_status_t amdsmi_get_power_measure	(	amdsmi_device_handle	device_handle,
		amdsmi_power_measure_t *	info
	)

Returns the current power and voltage of the GPU. The voltage is in units of mV and the power in units of W.

Parameters

[in]	device_handle	Device which to query
[out]	info	Reference to the gpu power structure. Must be allocated by user.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

amdsmi_status_t amdsmi_get_clock_measure	(	amdsmi_device_handle	device_handle,
		amdsmi_clk_type_t	clk_type,
		amdsmi_clk_measure_t *	info
	)

Returns the measurements of the clocks in the GPU for the GFX and multimedia engines and Memory. This call reports the averages over 1s in MHz.

Parameters

[in]	device_handle	Device which to query
[in]	clk_type	Enum representing the clock type to query.
[out]	info	Reference to the gpu clock structure. Must be allocated by user.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

amdsmi_status_t amdsmi_get_vram_usage	(	amdsmi_device_handle	device_handle,
		amdsmi_vram_info_t *	info
	)

Returns the VRAM usage (both total and used memory) in MegaBytes.

Parameters

[in]	device_handle	Device which to query
[out]	info	Reference to vram information. Must be allocated by user.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail
