<b>Subject:</b> [PATCH] drm/amdgpu: Fix channel_index table layout for Aldebaran</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt">
<div class="PlainText">Fix the channel_index table layout to fetch the correct<br>
channel_index when calculating physical address from<br>
normalized address during page retirement.<br>
Also, fix the number of UMC instances and number of channels<br>
within each UMC instance for Aldebaran.<br>
