Class reference

Subclass of CIM_PCIDevice

Capabilities and management of a PCI device controller on an adapter card.

Local properties

uint16 VendorID

Register that contains a value assigned by the PCI SIG used to identify the manufacturer of the device.

uint16 InterruptPin

Defines the PCI interrupt request pin (INTA# to INTD#) to which a PCI functional device is connected.

ValueMap Values
0 None
5 Unknown

string SubsystemVendorName

Name of the subsystem vendor

uint16 PCIDeviceID

Register that contains a value assigned by the device manufacturer used to identify the type of device.

string InstanceID

InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below.

To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following “preferred” algorithm:


Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>.

<LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above “preferred” algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance.

If not set to null for DMTF-defined instances, the “preferred” algorithm must be used with the <OrgID> set to CIM.

uint16[] Capabilities

An array of integers that indicates controller capabilities. Information such as “Supports 66MHz” (value=2) is specified in this property. The data in the Capabilities array is gathered from the PCI Status Register and the PCI Capabilities List as defined in the PCI Specification.

string SubsystemName

Name of the subsystem

string SystemName

The System Name of the scoping system.

uint64[] BaseAddress64

Array of doubleword base-memory addresses for 64 bit addresses

string ElementName

A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.

string Description

The Description property provides a textual description of the object.

uint8 RevisionID

Register that contains a value assigned by the device manufacturer used to identify the revision number of the device.

uint8 LatencyTimer

Defines the minimum amount of time, in PCI clock cycles, that the bus master can retain ownership of the bus.

uint16 SubsystemVendorID

Subsystem vendor ID. ID information is reported from a PCIDevice through protocol-specific requests. The correct place in the CIM Schema for this information is in CIM_Physical Element (the Manufacturer property) for hardware, and CIM_Product (the Vendor property) if the information is related to Product acquisition. This data is also reported here, because it is part of the standard output from the Device and is an optimization.

uint8 FunctionNumber

The function number for this PCI device.

string Name

The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.

string Caption

The Caption property is a short textual description (one- line string) of the object.

uint16 CommandRegister

Current contents of the register that provides basic control over the ability of the device to respond to or perform PCI accesses.

uint16 DeviceSelectTiming

The slowest device-select timing for a target device.

2 Fast
3 Medium
4 Slow
5 Reserved

string PCIDeviceName

Name of the device

uint16 SubsystemID

Subsystem identifier code.

uint32 ExpansionROMBaseAddress

Doubleword Expansion ROM-base memory address.

string VendorName

Name of the vendor

uint8 CacheLineSize

Specifies the system cache line size in doubleword increments (for example, a 486-based system would store the value 04h, indicating a cache line size of four doublewords.

uint8 BusNumber

The bus number where this PCI device resides.

uint8 ClassCode

Register of 8 bits that identifies the basic function of the PCI device. This property is only the upper byte (offset 0Bh) of the 3-byte ClassCode field. Note that the ValueMap array of the property specifies the decimal representation of this information.

uint8 DeviceNumber

The device number assigned to this PCI device for this bus.

string CreationClassName

CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.

uint32[] BaseAddress

Array of doubleword base-memory addresses.

string SystemCreationClassName

The CreationClassName of the scoping system.

string DeviceID

An address or other identifying information used to uniquely name the LogicalDevice.
