What soc is on you board? rk3566 or rk3568?

<p>RK3566? Maybe that is the problem.</p>

color-range=YCbCr limited range
<p>From your dri/state dump, Plane 43 is Esmart1.</p>
<p>Cluster1, Esmart1, Smart1 are special on rk3566, they are</p>
<p>mirror window of Cluster0, Esmart0, Esmart0. That means</p>
<p>the software can't program a independent framebuffer for</p>
<p>these three windows. They can only share the fb address set</p>
<p>in Cluster0, Esmart0, Smart0.</p>
<p>For rk3566, we only use it for two VP display same content:</p>
<p>assign Cluster0,Esmart0,Smart0 to VP1 for primary
display(MIPI),</p>
<p>assign Cluster1,Esmart1, Smart1 to VP0 for extend display(HDMI)</p>
<p>we handle this logic in Android hwc:</p>
<p>When a hdmi is connected, hwc will commit Esmart1 with Esmart0
with the <br>
</p>
<p>same fb and src buffer size, the dst can be different(by window
scale)</p>
<p><br>
</p>
<p>I have code comment in my downstream kernel and explained this
detail when Sascha start submit this serials.<br>

<pre class="moz-quote-pre" wrap="">I have a scripts[0] use io[1] command to dump the VOP2 register you can use it dump the register configuration when you meet a display failure,
then send the dump to me, maybe I can figure out something.

<pre class="moz-quote-pre" wrap="">I put dumps for following scenarios:
1.
-boot
-modetest -s 69@67:1920x1080 -> ok
-modetest -P 43@67:1920x1080@NV12 -> green screen
2.
-boot
-modetest -s 69@67:1920x1080 -> ok
-modetest -P 49@67:1920x1080@NV12 -> ok (but shifted horizontally by about 5% of screen width)
(setting palne#49 fixes plane #43. Here i set plane #49 but not yet setting #43)
3.

-modetest -s 69@67:1920x1080 -> ok
