Function Documentation

◆ rsmi_dev_compute_partition_get()

rsmi_status_t rsmi_dev_compute_partition_get ( uint32_t  dv_ind,
char *  compute_partition,
uint32_t  len 
)

Retrieves the current compute partitioning for a desired device.

Given a device index dv_ind 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]dv_inda device index
[in,out]compute_partitiona pointer to a char string variable, which the device's current compute partition will be written to.
[in]lenthe length of the caller provided buffer compute_partition
Return values
RSMI_STATUS_SUCCESScall was successful
RSMI_STATUS_INVALID_ARGSthe provided arguments are not valid
RSMI_STATUS_UNEXPECTED_DATAdata provided to function is not valid
RSMI_STATUS_NOT_SUPPORTEDinstalled software or hardware does not support this function with the given arguments
RSMI_STATUS_INSUFFICIENT_SIZEis returned if len bytes is not large enough to hold the entire compute partition value. In this case, only len bytes will be written.

◆ rsmi_dev_compute_partition_set()

rsmi_status_t rsmi_dev_compute_partition_set ( uint32_t  dv_ind,
rsmi_compute_partition_type_t  compute_partition 
)

Modifies a selected device's compute partition setting.

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

Parameters
[in]dv_inda device index
[in,out]compute_partitionusing enum ::rsmi_copmpute_partition_type_t, define what the selected device's compute partition setting should be updated to.
Return values
RSMI_STATUS_SUCCESScall was successful
RSMI_STATUS_PERMISSIONfunction requires root access
RSMI_STATUS_INVALID_ARGSthe provided arguments are not valid
RSMI_STATUS_NOT_SUPPORTEDinstalled software or hardware does not support this function with the given arguments
