hwlocality_rsmi(3)	   Hardware Locality (hwloc)	    hwlocality_rsmi(3)

NAME
       hwlocality_rsmi - Interoperability with the ROCm	SMI Management Library

SYNOPSIS
   Functions
       static int hwloc_rsmi_get_device_cpuset (hwloc_topology_t topology,
	   uint32_t dv_ind, hwloc_cpuset_t set)
       static hwloc_obj_t hwloc_rsmi_get_device_osdev_by_index
	   (hwloc_topology_t topology, uint32_t	dv_ind)
       static hwloc_obj_t hwloc_rsmi_get_device_osdev (hwloc_topology_t
	   topology, uint32_t dv_ind)

Detailed Description
       This interface offers ways to retrieve topology information about
       devices managed by the ROCm SMI Management Library.

Function Documentation
   static int hwloc_rsmi_get_device_cpuset (hwloc_topology_t topology,
       uint32_t	dv_ind,	hwloc_cpuset_t set) [inline],  [static]
       Get the CPU set of logical processors that are physically close to AMD
       GPU device whose	index is dv_ind. Return	the CPU	set describing the
       locality	of the AMD GPU device whose index is dv_ind.

       Topology	topology and device dv_ind must	match the local	machine. I/O
       devices detection and the ROCm SMI component are	not needed in the
       topology.

       The function only returns the locality of the device. If	more
       information about the device is needed, OS objects should be used
       instead,	see hwloc_rsmi_get_device_osdev() and
       hwloc_rsmi_get_device_osdev_by_index().

       This function is	currently only implemented in a	meaningful way for
       Linux; other systems will simply	get a full cpuset.

   static hwloc_obj_t hwloc_rsmi_get_device_osdev (hwloc_topology_t topology,
       uint32_t	dv_ind)	[inline],  [static]
       Get the hwloc OS	device object corresponding to AMD GPU device, whose
       index is	dv_ind.	Return the hwloc OS device object that describes the
       given AMD GPU, whose index is dv_ind Return NULL	if there is none.

       Topology	topology and device dv_ind must	match the local	machine. I/O
       devices detection and the ROCm SMI component must be enabled in the
       topology. If not, the locality of the object may	still be found using
       hwloc_rsmi_get_device_cpuset().

       Note
	   The corresponding hwloc PCI device may be found by looking at the
	   result parent pointer (unless PCI devices are filtered out).

   static hwloc_obj_t hwloc_rsmi_get_device_osdev_by_index (hwloc_topology_t
       topology, uint32_t dv_ind) [inline],  [static]
       Get the hwloc OS	device object corresponding to the AMD GPU device
       whose index is dv_ind. Return the OS device object describing the AMD
       GPU device whose	index is dv_ind. Returns NULL if there is none.

       The topology topology does not necessarily have to match	the current
       machine.	For instance the topology may be an XML	import of a remote
       host. I/O devices detection and the ROCm	SMI component must be enabled
       in the topology.

       Note
	   The corresponding PCI device	object can be obtained by looking at
	   the OS device parent	object (unless PCI devices are filtered	out).
