Hi ,

IMX6 quad core processor supports the multiple cores. How these cores are interfaced with the GIC and when any interrupt occurs , which core will serve the interrupt , how it is decided. Please suggest.

Regards,

Aditya Nagal

Hello,

   Usually it is recommended to use Irqbalance utility, which is especially useful on
systems with multi-core processors, as interrupts will typically only be serviced
by the first core.

Yuri.

Hello Aditya,

in Linux only core0 handles interrupts. And the GIC is a module provided inside ARM processor so you may refer to ARM for the documentation.
