That should work but if you run into trouble you can always check:

Thanks again, will go back and turn off amdgpu and turn on radeon in the kernel 
configuration. As far as you are aware will the KAVERI firmware in the old  
meta-baldeagle layer still work?

That's true but as we haven't verified how well it works and on the other hand 
the radeon driver is proved to work I'd stick to that.

Thanks for the advice, when I get a bit more time I will retry. I understood 
that amdgpu will support the Bald Eagle (albeit not very well until kernel 
4.15), would you recommend I stick with the radeon kernel drivers for now?

Odd, this should've worked. I believe looking through the kernel config/compile 
logs would help. Also, the kernel boot log should hint as to what might be 
going wrong.

The meta-v1000 layer (supporting the V1000 BSP) has an amdgpu while the Bald 
Eagle uses radeon and the overrides in these layers have been maintained 
accordingly. You'll probably need to pick up changes after a bit of inspection.

Hi Awais,

I applied no patches to the 4.9.49 Yocto Linux sources when attempting to use 
the machine definition for Bald Eagle I brought forward from the jethro branch 
(see the previous  post). I could not get this setup to boot at all after 
playing around for a day or so. I suspect a bad kernel configuration was the 
root cause. I have now abandoned this idea.

I am now having much better success i.e. I am booting to the console, by using 
the meta-yocto-bsp “genericx86-64” machine definition with the default 4.9.49 
kernel configuration (arrived at via bitbake virtual/kernel -c 
kernel_configme). My goal is to get a working graphics stack for the 2nd 
Generation R-Series APU. The layers that define our distribution are at present 
constrained to use the Yocto pyro release and a version 4.9.x kernel.
To this end I have been looking at the meta-v1000 layer and plan to follow the 
patterns there to get a working graphics stack. Do you think this is good or 
bad idea?

BTW the hardware I have works fine under Ubuntu 16.04 so I can rule out any 
hardware related issues.

Hi Peter,

Can  you please share the panic logs? Also are you using any patches on top of 
the 4.9 base kernel?
