<p>CPU naming is fairly easy to figure out as well, open your decompiled DSDT and search for <code>Processor</code>. This should give you a result like this:</p>
|

<p><img src="../images/Universal/plug-md/processor.png" alt=""></p>
|
||||
<p>As we can see, the first processor in our list is <code>PR00</code>. This is what we'll be applying the <code>plugin-type=1</code> property too. Now grab <a href="https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-PLUG.dsl" target="_blank">SSDT-PLUG</a> and replace the default <code>CPU0</code> with our <code>PR00</code>.

There's a couple things to note:</p>
|
||||
<ul>
|
||||
<li>There's 2 mentions of CPU0 to change</li>
|
||||
<li>The <code>PR</code> path may need to be changed, in our example we can see that our <code>PR00</code> has <code>SB</code> in front.</li>
|
||||
</ul>
|
||||
<p>So in our final example, we'd have <code>_SB_.PR00</code> and <code>\_SB.PR00</code></p>
|
||||
<ul>
|
||||
<li><strong>Note</strong>: If you're having issues, see the <a href="https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-PLUG.dsl" target="_blank">SSDT-PLUG</a> provided by Acidanthera for example on what other ACPI paths may look like.</li>
|
||||
</ul>
|
||||
<p>There are also some edge cases with <code>Processor</code>, specifically on HEDT series like X79, X99 and X299. This edge case is that the ACPI path is much longer and not so obvious:</p>
|

<p><img src="../images/Universal/plug-md/processor-2.png" alt=""></p>

<p>If we then search for instances of <code>CP00</code> we find that it's ACPI path is <code>SB.SCK0.CP00</code>:</p>
