<b>Subject:</b> [PATCH] drm/amdgpu: Add dcdebugmask option to enable DPIA trace</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">[Why & How]<br>
It's useful to be able to enable DPIA trace with dcdebugmask<br>
option, especially to debug DPIA issues involved in transition<br>
of system power states.<br>
<br>
This patch adds an option to amdgpu.dcdebugmask to be picked up<br>
by amdgpu DM to enable DPIA trace.<br>
<br>
