Detailed Description

These functions are used to configure and query the device's compute parition setting.

Function Documentation

◆ amdsmi_get_gpu_compute_partition()

amdsmi_status_t amdsmi_get_gpu_compute_partition	(	amdsmi_processor_handle	processor_handle,
		char *	compute_partition,
		uint32_t	len
	)

Retrieves the current compute partitioning for a desired device.

Platform:

gpu_bm_linux

Given a processor handle processor_handle and a string compute_partition , and uint32 len , this function will attempt to obtain the device's current compute partition setting string. Upon successful retreival, the obtained device's compute partition settings string shall be stored in the passed compute_partition char string variable.

Parameters

[in]	processor_handle	Device which to query
[in,out]	compute_partition	a pointer to a char string variable, which the device's current compute partition will be written to.
[in]	len	the length of the caller provided buffer compute_partition , suggested length is 4 or greater.

Return values

AMDSMI_STATUS_SUCCESS	call was successful
AMDSMI_STATUS_INVAL	the provided arguments are not valid
AMDSMI_STATUS_UNEXPECTED_DATA	data provided to function is not valid
AMDSMI_STATUS_NOT_SUPPORTED	installed software or hardware does not support this function
AMDSMI_STATUS_INSUFFICIENT_SIZE	is returned if len bytes is not large enough to hold the entire compute partition value. In this case, only len bytes will be written.

◆ amdsmi_set_gpu_compute_partition()

amdsmi_status_t amdsmi_set_gpu_compute_partition	(	amdsmi_processor_handle	processor_handle,
		amdsmi_compute_partition_type_t	compute_partition
	)

Modifies a selected device's compute partition setting.

Platform:

gpu_bm_linux

Given a processor handle processor_handle, a type of compute partition compute_partition, this function will attempt to update the selected device's compute partition setting.

Parameters

[in]	processor_handle	Device which to query
[in]	compute_partition	using enum amdsmi_compute_partition_type_t, define what the selected device's compute partition setting should be updated to.

Return values

AMDSMI_STATUS_SUCCESS	call was successful
::AMDSMI_STATUS_PERMISSION	function requires root access
AMDSMI_STATUS_INVAL	the provided arguments are not valid
AMDSMI_STATUS_SETTING_UNAVAILABLE	the provided setting is unavailable for current device
AMDSMI_STATUS_NOT_SUPPORTED	installed software or hardware does not support this function
