| <h1>irqinfo<a class="headerlink" href="#irqinfo" title="Permalink to this heading"></a></h1> |
| <p><code class="docutils literal notranslate"><span class="pre">irqinfo</span></code> 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.</p> |
| <p>The argument is displayed as function if possible.</p> |
| <p>It’s similar to nsh command <code class="docutils literal notranslate"><span class="pre">irqinfo</span></code> but works in GDB. See <a class="reference internal" href="../../applications/nsh/commands.html#cmdirqinfo"><span class="std std-ref">irqinfo Show Interrupt Status</span></a> for more information.</p> |
