Function Documentation

rsmi_dev_memory_partition_get()

rsmi_status_t rsmi_dev_memory_partition_get	(	uint32_t	dv_ind,
		char *	memory_partition,
		uint32_t	len
	)

Retrieves the current memory partition for a desired device.

Given a device index dv_ind and a string memory_partition , and uint32 len , this function will attempt to obtain the device's memory partition string. Upon successful retreival, the obtained device's memory partition string shall be stored in the passed memory_partition char string variable.

Parameters

[in]	dv_ind	a device index
[in,out]	memory_partition	a pointer to a char string variable, which the device's memory partition will be written to.
[in]	len	the length of the caller provided buffer memory_partition , suggested length is 5 or greater.

Return values

RSMI_STATUS_SUCCESS	call was successful
RSMI_STATUS_INVALID_ARGS	the provided arguments are not valid
RSMI_STATUS_UNEXPECTED_DATA	data provided to function is not valid
RSMI_STATUS_NOT_SUPPORTED	installed software or hardware does not support this function
RSMI_STATUS_INSUFFICIENT_SIZE	is returned if len bytes is not large enough to hold the entire memory partition value. In this case, only len bytes will be written.

rsmi_dev_memory_partition_set()

rsmi_status_t rsmi_dev_memory_partition_set	(	uint32_t	dv_ind,
		rsmi_memory_partition_type_t	memory_partition
	)

Modifies a selected device's current memory partition setting.

Given a device index dv_ind and a type of memory partition memory_partition, this function will attempt to update the selected device's memory partition setting.

Parameters

[in]	dv_ind	a device index
[in]	memory_partition	using enum rsmi_memory_partition_type_t, define what the selected device's current mode setting should be updated to.

Return values

RSMI_STATUS_SUCCESS	call was successful
RSMI_STATUS_PERMISSION	function requires root access
RSMI_STATUS_INVALID_ARGS	the provided arguments are not valid
RSMI_STATUS_NOT_SUPPORTED	installed software or hardware does not support this function
RSMI_STATUS_AMDGPU_RESTART_ERR	could not successfully restart the amdgpu driver
RSMI_STATUS_BUSY	A resource or mutex could not be acquired because it is already being used - device is busy

rsmi_dev_memory_partition_reset()

rsmi_status_t rsmi_dev_memory_partition_reset

(

uint32_t

dv_ind

)

Reverts a selected device's memory partition setting back to its boot state.

Given a device index dv_ind , this function will attempt to revert its current memory partition setting back to its boot state.

Parameters

[in]

dv_ind

a device index

Return values

RSMI_STATUS_SUCCESS	call was successful
RSMI_STATUS_PERMISSION	function requires root access
RSMI_STATUS_NOT_SUPPORTED	installed software or hardware does not support this function
RSMI_STATUS_AMDGPU_RESTART_ERR	could not successfully restart the amdgpu driver
RSMI_STATUS_BUSY	A resource or mutex could not be acquired because it is already being used - device is busy
