<p class="Pp">The <code class="Nm">linuxkpi</code> kernel module provides a
    limited KPI (kernel programming interface) to allow Linux kernel drivers and
    other Linux kernel code to be compiled on <span class="Ux">FreeBSD</span>
    and used along the <span class="Ux">FreeBSD</span> kernel with little or no
    modification.</p>
<p class="Pp" id="OpenFabrics">While historically
    <a class="permalink" href="#OpenFabrics"><i class="Em">OpenFabrics
    Enterprise Distribution (Infiniband)</i></a>, and certain vendor drivers
    have used <code class="Nm">linuxkpi</code>.
    <a class="permalink" href="#drm-kmod"><i class="Em" id="drm-kmod">drm-kmod</i></a>
    for graphics driver support and <a class="Xr">linuxkpi_wlan(4)</a> for
    wireless drivers are prominent consumers.</p>
<p class="Pp"><code class="Nm">linuxkpi</code> is not to be confused with
    <a class="Xr">linux(4)</a> which provides limited Linux ABI (application
    binary interface) compatibility to allow running Linux application binaries
    unmodified on <span class="Ux">FreeBSD</span>.</p>
