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...
IRQ handling can impact power consumption in computing systems. Excessive IRQ activity, particularly when dealing with poorly optimized drivers or malfunctioning devices, can result in higher central processing unit (CPU) usage, leading to increased power consumption. Efficient IRQ management helps conserve...
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...
