Hi,<br>

I am unsure if this is the right place to ask, but
it seems relevant.<br>

I am trying to use an AMD E8860 (SI) board connected
to an E6500 PowerPC<br>
board (T2080RDB from NXP).<br>
The T2080RDB does not use a BIOS, and uses u-boot to
bootstrap Linux.<br>
<br>
I have the E8860 connected to a PCIe x4 slot with an
adapter. The kernel<br>
is a 4.1, with DRM included in the kernel and the
radeon as a module.<br>
The radeon driver detects the card, notices the BIOS
hasn't posted and<br>
starts things up.<br>
After that, the ring tests get run, and fails on the
ring 0 test,<br>
disabling acceleration. The graphics card is (or
seems to be) working<br>
apart from that, the driver starts up and sees the
connectors on the board.<br>
<br>
When I compare dmesg on an x86 machine and the PPC
machine, I see that<br>
the x86 machine loads a lot more firmware from the
kernel (probably the<br>
acceleration parts?).<br>
</blockquote>
FWIW, that's probably just a subsequent symptom due to
the ring test<br>
failure.<br>
</blockquote>
<br>
</span>
Could be, but IIRC we load all the firmware first then
initialize things and then do the ring tests when we try
to start the rings.<br>
<br>
BTW: What driver are you using? radeon or amdgpu?</blockquote>
<div><br>
</div>
<div>This is a south-island or sea-island chip, so using
radeon.</div>
</div>
</div>
</div>
</blockquote>
<br>
Well SI is also supported by amdgpu, I would give that a try as
well.<br>
<br>
And BTW please try a more recent kernel as well, 4.1 is rather old.<br>

My question is, what do I need to do to correctly
initialize the E8860<br>
board on my powerpc machine?<br>
</blockquote>
Start by sharing the dmesg output, and maybe also the
kernel build<br>
configuration file.<br>
</blockquote>
<br>
</span>
Maybe also open a bug report to attach the dmesg, see <a

</div>
<div>Sure. What project does the radeon driver fall under? I
couldn't find the right category under Mesa, not sure what</div>
<div>to file it under.</div>
</div>
</div>
</div>
</blockquote>
<br>
Product DRI and then select DRM/Radeon as component.<br>
