[install-section-name.HW] AddReg=add-registry-section [add-registry-section] HKR, "Interrupt Management\Affinity Policy", DevicePolicy, 0x00010001, 2 The system makes the registry settings available to the device's driver when it sends the IRP_MN_FILTER_RESOURCE_REQUIREMENTS IRP to the driver....
I have a driver that sets the interrupt affinity mask in HKLM\SYSTEM\CurrentControlSet\Enum\PCI\PNPID]\ID]\Device Parameters\Interrupt Management\Affinity Policy - Temporal . The key contains TargetSet (QWORD) and TargetGroup (DWORD). When I select that device in the Interrupt Policy Configurati...
下列程式代碼範例會呼叫WDF_INTERRUPT_EXTENDED_POLICY_INIT來初始化WDF_INTERRUPT_EXTENDED_POLICY結構;會設定原則、優先順序和目標處理器集的值;並呼叫SetExtendedPolicy。 此範例會設定中斷的一般優先順序,並將中斷指派給處理器群組 2 中的處理器 0。 IWDFInterrupt* pInterrupt; #define AFFINITY_MASK(n) (...
Learn how the WDF_INTERRUPT_POLICY enumeration type identifies the affinity policies that the PnP manager can use when it assigns a device's interrupts to the processors of a multiprocessor system.
This value is passed in the interrupt resource at u.Interrupt.Affinity.[in] FloatingSaveSpecifies whether to save the floating-point stack when the driver's device interrupts. For x86-based and Itanium-based platforms, this value must be set to FALSE. For more information about saving floating...

The present invention discloses a method for affinity binding of interrupt of a virtual network interface card, and a computer device. The method includes: receiving a request message sent by an IaaS resource management system, where the request message carries an interrupt affinity policy parameter...
WdfIrqPolicyMachineDefault Use the system's default affinity policy. WdfIrqPolicyAllCloseProcessors For NUMA systems, the PnP manager should assign the device's interrupts to processors that are close to the device. For non-NUMA systems, specifyingWdfIrqPolicyAllCloseProcessorsis the same as specifying...
