Public bug reported:

libdrm has an interface that is used by a variety of software (such as
GNOME about dialog, nvtop, rocminfo etc) to describe the GPU connected
to the system.

libdrm by default will try to match an AMD GPU to lines in amdgpu.ids.
If there is no match it will fall back to "Radeon Graphics".

This is a constant game of cat and mouse because every single SKU of a
new product needs a line added.

On APUs this is unnecessary though.  The string that comes from
/proc/cpuinfo describing the model comes from the hardware itself.

A change has been made in upstream libdrm that will prefer this string
when working on an APU instead of the amdgpu.ids file.

Can you please bring this patch into a future upload for libdrm ?
