} dmi_intel_rsd_pcie_t;Description
The dmi_intel_rsd_pcie_t structure holds the decoded PCIe information
structure (type 192) of Intel Rack Scale Design (RSD) firmware: one PCIe
device of the system, with its PCI identity, the slot it is installed in, and
the current state of its link.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(intel_rsd_pcie), once the Intel RSD extension module
(dmi_intel_rsd_module, declared in <opendmi/module/intel-rsd.h>) has been
enabled in the context with dmi_add_extension(). It lives as long as the
context it has been decoded in.
Fields
pci_class-
PCI class code of the device, which tells its generic function.
pci_slot_id-
Physical number of the slot the device is installed in. It matches the slot ID of the system slot structure (type 9) of that slot.
vendor_id-
PCI vendor identifier of the device.
device_id-
PCI device identifier of the device.
sub_vendor_id-
PCI subsystem vendor identifier, which tells the specific model.
sub_device_id-
PCI subsystem device identifier, which tells the specific model.
link_speed-
Current speed of the link, as the firmware reports it.
link_width-
Current width of the link, in lanes: 1, 2, 4, 8, 16, and so on.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(intel_rsd_pcie), true);
dmi_intel_rsd_pcie_t *device = dmi_entity_info(entity,
DMI_TYPE(intel_rsd_pcie));
if (device != nullptr)
printf("Slot %u: %04X:%04X, x%u\n", (unsigned)device->pci_slot_id,
(unsigned)device->vendor_id, (unsigned)device->device_id,
(unsigned)device->link_width);
