<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>
