irqinfo
=======

``irqinfo`` is a custom GDB command that prints information about the IRQs in the system.
The output includes the IRQ number, the number of times the IRQ has been triggered,
the total time spent in the IRQ handler, the rate of the IRQ, the IRQ handler function,
and the handler's argument.

The argument is displayed as function if possible.

It's similar to nsh command ``irqinfo`` but works in GDB. See :ref:`cmdirqinfo` for more information.

The ``RATE`` column is not available.

.. tip::
    To show the ``COUNT`` column, you need to enable the ``CONFIG_SCHED_IRQMONITOR`` option in the NuttX configuration.
