What is interrupt steering settings?
PCI IRQ steering is a feature created to fix problems with interrupt sharing between PCI cards on computers. When enabled, PCI IRQ Steering allows two or more PCI cards to use the same interrupt by dynamically mapping the devices interrupt using PnP.
What is an IRQ conflict?
An IRQ conflict happens when two devices attempt to use the same IRQ number, and the operating system or motherboard has no mechanism for accommodating this. These conflicts were common in older versions of Windows, but occur only rarely in modern versions of the operating system.

The descriptor structure contains status information and pointers to the interrupt flow method and the interrupt chip structure which are assigned to this interrupt. Whenever an interrupt triggers, the low-level architecture code calls into the generic interrupt code by calling desc->handle_irq ().

How to Kill a Process in Linux using SIGKILL Sometime -SIGTERM (-15) fails, the stronger signal 9, called SIGKILL, should be used for force killing of process. For example, the following command would guarantee that process 27707 would be killed: kill -9 27707
When does disable _ IRQ ( ) mask an interrupt?
This per interrupt selectable feature, which was introduced by Russell King in the ARM interrupt implementation, does not mask an interrupt at the hardware level when disable_irq () is called. The interrupt is kept enabled and is masked in the flow handler when an interrupt event happens.
