+<p class="Pp"><span class="Ux">FreeBSD</span> provides machine-independent bus
+ support and raw drivers for <code class="Nm">firewire</code> interfaces.</p>
+<p class="Pp">The <code class="Nm">firewire</code> driver consists of two
+ layers: the controller and the bus layer. The controller attaches to a
+ physical bus (like <a class="Xr">pci(4)</a>). The
+ <code class="Nm">firewire</code> bus attaches to the controller. Additional
+ drivers can be attached to the bus.</p>
+<p class="Pp">Up to 63 devices, including the host itself, can be attached to a
+ <code class="Nm">firewire</code> bus. The root node is dynamically assigned
+ with a PHY device function. Also, the other <code class="Nm">firewire</code>
+ bus specific parameters, e.g., node ID, cycle master, isochronous resource
+ manager and bus manager, are dynamically assigned, after bus reset is
+ initiated. On the <code class="Nm">firewire</code> bus, every device is
+ identified by an EUI 64 address.</p>
+<p class="Pp">Debugging over the firewire interface is possible with the
+ <a class="Xr">dcons(4)</a> driver. Please see
+ <a class="Lk" href="https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/#kerneldebug-dcons">https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/#kerneldebug-dcons</a>
+ for details on how to setup debugging with firewire.</p>
