AMD SMI: VF and FB partitioning queries

Functions
amdsmi_status_t	amdsmi_get_num_vf (amdsmi_processor_handle processor_handle, uint32_t num_vf_enabled, uint32_t num_vf_supported)
	Returns the number of VFs enabled by gpuv in the ASIC. More...

amdsmi_status_t	amdsmi_set_num_vf (amdsmi_processor_handle processor_handle, uint32_t num_vf)
	Enable a given number of VF. More...

amdsmi_status_t	amdsmi_get_vf_partition_info (amdsmi_processor_handle processor_handle, unsigned int vf_buffer_num, amdsmi_partition_info_t *info)
	Returns the current framebuffer partitioning structure as currently configured by the driver. More...

amdsmi_status_t amdsmi_get_num_vf	(	amdsmi_processor_handle	processor_handle,
		uint32_t *	num_vf_enabled,
		uint32_t *	num_vf_supported
	)

Returns the number of VFs enabled by gpuv in the ASIC.

Parameters

[in]	processor_handle	PF of a processor for which to query
[out]	num_vf_enabled	Reference to number of VF enabled. Must be allocated by user.
[out]	num_vf_supported	Reference to number of VF supported. Must be allocated by user.

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

amdsmi_status_t amdsmi_set_num_vf	(	amdsmi_processor_handle	processor_handle,
		uint32_t	num_vf
	)

Enable a given number of VF.

Parameters

[in]	processor_handle	PF of a processor for which to query
[in]	num_vf	- Number of VFs to enable.

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

amdsmi_status_t amdsmi_get_vf_partition_info	(	amdsmi_processor_handle	processor_handle,
		unsigned int	vf_buffer_num,
		amdsmi_partition_info_t *	info
	)

Returns the current framebuffer partitioning structure as currently configured by the driver.

Parameters

[in]	processor_handle	PF of a processor for which to query
[in]	vf_buffer_num	Size of the buffer where the library will copy the data in units of VF
[out]	info	Reference to structure with the current partitioning information. Must be allocated by user.

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