Are you remembering to add in the firmware to the kernel
image too?<br>

<div>i copied all from official linux-firmware.gif to

That's not sufficient, you need to tell the kernel explicitly which
firmware will be needed.<br>
<br>
In other words try mentioning everything in /lib/firmware/amdgpu as
CONFIG_EXTRA_FIRMWARE.<br>
<br>

I've successfully used AMDGPU builtin on Tonga, Raven,
Renoir and Navy<br>
Flounder systems<br>
<br>
I've never used kexec so have no suggestions for that<br>
