Yes, we should probably release the latest one instead of reusing
the one used with radeon.<br>
<br>
BTW: Does VCE work on CIK? Alex, don't we run into the same issue
there as well?<br>

UVD and VCE are actually needed for correct power management. When
the blocks fail to initialize you usually sooner or later run into
problems with power management (e.g. stuck inside a certain power
level).<br>

Well you could, but to be honest without AMD releasing new
firmware that is most likely a futile effort.<br>

</div>
<div>I've been working on porting VCE1 from radeon to amdgpu in
the last few weeks. I'm pretty much done and I've enabled the
functionality to see how it goes. However, I ended up with an
error on the firmware validation (size doesn't seem to fit),
thus failing completely in loading the driver. I'm testing on
a R9 280X (Tahiti).</div>

<div>Three questions then:</div>
<div>- Would we need a different firmware version with a
different "hdr" for the amdgpu driver?</div>
<div>- Wouldn't it be better to continue loading the driver
while having VCE disabled IF we fail when loading or

in memory and no registry have been modified up to that point.</div>
