| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| Availability | uint16 | |
| Description | string | Availability of the IRQ. |
| MappingStrings | string | MIF.DMTF|IRQ|002.2 |
| ValueMap | string | 1, 2, 3, 4, 5 |
| Values | string | Other, Unknown, Available, In Use/Not Available, In Use and Available/Shareable |
| CreationClassName | string | |
| Description | string | 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. |
| Key | boolean | true |
| MaxLen | uint32 | 256 |
| CSCreationClassName | string | |
| Description | string | The scoping ComputerSystem's CreationClassName. |
| Key | boolean | true |
| MaxLen | uint32 | 256 |
| Propagated | string | CIM_ComputerSystem.CreationClassName |
| CSName | string | |
| Description | string | The scoping ComputerSystem's Name. |
| Key | boolean | true |
| MaxLen | uint32 | 256 |
| Propagated | string | CIM_ComputerSystem.Name |
| Hardware | boolean | |
| Description | string | The Hardware property indicates whether the interrupt is hardware or software based. (If TRUE, the interrupt is hardware based.) On a personal computer, a hardware IRQ is a physical wire to a programmable interrupt controller (PIC) chip, through which the CPU can be notified of time critical events. Some IRQ lines are reserved for standard Devices such as the keyboard, floppy disk drives, and the system clock. A software interrupt is a programmatic mechanism to allow an application to get the attention of the Processor. |
| IRQNumber | uint32 | |
| Description | string | A part of the object's key value, IRQ Number. |
| Key | boolean | true |
| MappingStrings | string | MIF.DMTF|IRQ|002.1 |
| Shareable | boolean | |
| Description | string | Boolean indicating whether the IRQ can be shared. |
| MappingStrings | string | MIF.DMTF|IRQ|002.4 |
| Override | string | Shareable |
| TriggerLevel | uint16 | |
| Description | string | IRQ trigger level indicating whether the interrupt is triggered by the hardware signal going high (value=4) or low (value=3). Also, "Other" (1) and "Unknown" (2) may be defined. |
| MappingStrings | string | MIF.DMTF|System Resource IRQ Info|001.3 |
| ValueMap | string | 1, 2, 3, 4 |
| Values | string | Other, Unknown, Active Low, Active High |
| TriggerType | uint16 | |
| Description | string | IRQ trigger type indicating whether edge (value=4) or level triggered (value=3) interrupts occur. Also, "Other" (1) and "Unknown" (2) may be defined. |
| MappingStrings | string | MIF.DMTF|IRQ|002.3, MIF.DMTF|System Resource IRQ Info|001.2 |
| ValueMap | string | 1, 2, 3, 4 |
| Values | string | Other, Unknown, Level, Edge |
