Fix Amdgpu-18.10.572953 DMKS modules failed installation for kernel 4.16.0-041600 ?

My AMD GPU is:

  • 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8400 / R3 Series] [1002:9830] (prog-if 00 [VGA controller])
  • Subsystem: Hewlett-Packard Company Kabini [Radeon HD 8400 / R3 Series]
  • Kernel driver in use: amdgpu
  • Kernel modules: radeon, amdgpu

OS:

  • Distributor ID: Ubuntu
  • Description: Ubuntu 16.04.4 LTS
  • Release: 16.04
  • Codename: xenial

Active kernel (For scope of this question):

  • Linux UbuntuHP 4.16.0-041600-generic #201804012230 SMP Sun Apr 1 22:31:39 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I'm using the amdgpu-dkms package from amdgpu-pro-18.10-572953 installed onto Ubuntu 16.04.4: Radeon™ Software for Linux 18.10 Release Notes

The build fails for any kernel over 4.4 (however the irony is that only kernel 4.16 will actually switch the driver over from radeon to amdgpu for my card (when I blacklist radeon in /etc/modprobe.d/blacklist-radeon.conf), but runs without the dkms modules, and uses only the stock modules shipped with the kernel in (see attached file : https://community.amd.com/servlet/JiveServlet/download/2862543-96698/amdgpu_modinfo.txt.zip ):

  • /lib/firmware/amdgpu
  • /lib/firmware/4.16.0-041600-generic/amdgpu
  • /lib/modules/4.16.0-041600-generic/kernel/drivers/gpu/drm/amd/amdgpu

$ lsmod | grep amdgpu

amdgpu               2727936  6

chash                      16384  1 amdgpu

gpu_sched              24576  1 amdgpu

i2c_algo_bit             16384  2 amdgpu,radeon

ttm                         106496  2 amdgpu,radeon

drm_kms_helper   172032  2 amdgpu,radeon

drm                        401408  8 amdgpu,radeon,gpu_sched,ttm,drm_kms_helper

**Note: After the kernel switched over to amdgpu, I had to remove the blacklist for radeon so i could still use the older kernel (4.4), however in kernel 4.16 it still retains the amdgpu driver over radeon (irregardless if I remove the blacklist after the fact), in 4.4 it never switches over if I blacklist radeon

DKMS Build Log:

Is it possible to fix this ? Seems AMD might have to update their code to support the newer kernels, which also 4.17 will be getting shipped soon. Unless ofc the modules that 4.16 has is sufficient already.

You're asking if HP is providing the graphics drivers for linux ? If so that's not possible as this laptop was built with windows 8, and HP support only support windows drivers. I'm on linux ...

See for yourself: Contact HP Customer Support | HP® Customer Support   and type CND5052339 for the serial #. You will see they don't provide linux support.

And as I said in the original post.. the DKMS module SUCCESSFULLY built for kernel 4.4.0-127, just NOT 4.16.0-041600. Hence why I included the make log which is showing why the code isn't building.... This requires attention of the techs that created the dkms to look that over and see at having it made compatible to the new kernel headers.

In regards to the driver that's being loaded at boot time, it's confusing as to why 4.16.0-04166 kernel loads amdgpu driver when I blacklist radeon, but on 4.4.0-127 it doesn't. But the situation with the DKMS modules is reversed.
