Technical Tip: Explaining IRQ in 'get system performance status' command output

IRQ can be seen in the results of 'get sys perf status':

IRQ allows the devices to notify the kernel that needs attention, which includes:

• Hardware Interrupts: Hardware interrupts affect the CPU directly.
• Software Interrupts: These are like hardware interrupts, but they can only be generated by the process that is currently running.

Devices with high bandwidth may distribute interrupts to multiple cores using multiple IRQs(NP6 or NP4).

View interrupts using the 'diag hard sys interrupts' command for hardware. For software, use the 'fnsysctl cat /proc/softirqs' command.
