WebFeb 18, 2015 · 1. Check if your kernel is built with CONFIG_REGMAP_IRQ=Y. If not, you will not be able to map IRQs to CPUs. Bear in mind that even if IRQ mapping is enabled, there may be hardware limitation preventing a particular IRQ from being remapped. There are interrupts which are specific to a given core (a prime example is the division by zero IRQ … WebMay 8, 2010 · /proc/irq/default_smp_affinity specifies default affinity mask that applies to all non-active IRQs. Once IRQ is allocated/activated its affinity bitmask will be set to the default mask. It can then be changed as described above. Default mask is 0xffffffff.

WebMar 27, 2024 · IRQ affinity controls. Current driver aggregates multiple events/IRQ to single wired IRQ line/VINT thus making it impossible to migrate events selectively. In order to overcome this limitation, reserve a set of VINTs as direct interrupts and map them to events that are known to generate high IRQ Use SoC specific table to determine such events. WebJan 27, 2014 · We can manually change the processor affinity by changing values in smp_affinity file for a particular controller or by using irqbalance. IRQ Balance Irqbalance is a Linux utility that distributes interrupts over the processor cores in your computer system which helps to improve performance.
