Commen= t # 3 on bug 10852= 1 from Robert Strube 
Quick question:

Is it possible to completely disable the Vega M using kernel boot parameter=
s.=20
I did try using pci-stub.ids=3Dxxxx:xxxx with the PCI hex id for my Vega M
(1002:694e) but amdgpu was still applied to the device, not sure why.  I al=
so
thought there was explicit PCI device blacklisting support in the kernel, b=
ut I
have been unable to find any documentation on this.

Ideally I'd like to see if having the Vega M disabled allows the eGPU to be
correctly initialized.  I took a look at the documentation for amdgpu, but I
didn't see any boot parameters that stood out at me.

Blacklisting the amdgpu module wouldn't work either, as I need that to
correctly support the RX 580 once it's attached.

Thanks!
