Detailing the installation of AMD OpenCL rpm for Fedora

Revisiting the previous blog and freshly reinstalling Fedora Design Suite due to a busted boot, I look at the official guideline from AMD Driver for Red Hat Enterprise Linux 7.2 and write a way to improve the process of installing on Fedora 29 in this example.



Extracting the tarball contains the following:
  • amdgpu-install
  • amdgpu-pro-install symlink to amdgpu
  • doc folder
  • repodata folder
  • RPMS folder containing rpm package

Executing the command ./amdgpu-install -opencl=pal --headless sadly failed on Fedora on that line:

./amdgpu-install -y --opencl=pal --headless
Last metadata expiration check: 0:30:51 ago on Mon 19 Nov 2018 07:13:43 PM PST.
No match for argument: amdgpu


Upon closer look, the script failed to created a temporary repository on /var/opt/amdgpu-pro-local probably explaining why amdgpu metapackage name failed to display. Someone should investigate and provide a fix. At least, we find out Fedora support is available but unofficial.

Due to its design, Gnome Software only allows one click package per installation, not by selection, so terminal remains the logical option.

Learning the new version on AMD Radeon 18.40 driver no longer needs dkms for installing OpenCL, the process is much easier without requiring kernel-devel package. The following dependencies are now:
  • amdgpu-core (core metapackage)
  • amdgpu-pro-core (metapackage of amdgpu-pro)
  • clinfo-amdgpu-pro
  • libopencl-amdgpu-pro
  • opencl-amdgpu-pro-icd
Installing amdgpu-core alone causes dnf to complain about support for Red Hat Enterprise Linux 7.5 due the script extracted from rpmrebuild -p -e command:

if [ $(rpm --eval 0%%{?rhel}) != "07" ] ; then
        >&2 echo "ERROR: This package can only be installed on EL7."
        exit 1
fi


Selecting all above dependencies overrides it and completes the installation despite a failure of a scriptlet from amdgpu-core.  OpenCL now available will be automatically detected by applications like Blender, Darktable,LibreOffice and Gimp.

We learned it is possible to install AMD version of OpenCL on Fedora. We also learn it is possible to retrace the spec file using rpmrebuild -e -p command. Additionally, we also find out  the open source amdpgu and the pro version can coexist.

 All test done on HP Envy x360 Ryzen 2500U with integrated Vega8 using Vega56 driver for CentOS 7.5 from the official AMD website.

Using AMD RX Vega driver OpenCL on Fedora 29

The Raven Ridge APU is very capable processor to handle OpenCL inside some applications like Blender, Darktable and Gimp. Unfortunately, the current implementation from Mesa, clover, stuck to 1.3, is not supported. AMD released their driver 18.40 with OpenCL2.0+ targeting only Red Hat Enterprise Linux/Cent OS 6.10 and 7.5 in addition of Ubuntu LTS. The good new is the former rpm format can be used on Fedora.

The graphical part of Raven Ridge is Vega 8, basically a cut-down of Vega56 or Vega64 meaning choosing either driver for RX Vega.
The instruction is provided for extracting the rpm files but here is
 some requirements for OpenCL:
kernel-devel (provided by Fedora repository)amdgpu-dkmsdkmslibopencl-amdgpu-proopencl-amdgpu-pro-icd Once done, applications needing OpenCL will automatically detect the driver located on /opt/amdgpu/lib64. Blender will list as unknown AMD GPU and Darktable will enable it.



There is a ROCm version but it currently does not support the graphical side of Rav…

Fedora 29 Design Suite Lab available

Fedora 29 Design Suite is available for downloading with latest stable release  applications including Gimp 2.10.6 among the features.
On the bad news side, Blender 2.79b on Fedora 29 has broken user interface due to compatibility issue related to python 3.7. Workaround will be installing from the flathub directory.

Next release will be interesting considering the structural change for the incoming Fedora 30 with the advent of flatpak packages.

HP Envy x360 Convertible Ryzen 2500u update

Nearly one month later, HP Envy x360 Convertible 15  powered by Ryzen 2500U is running smoother on kernel 4.19.0 with someissues:
The LED for the mute button failed to work suggesting a possible ACPI issue.An unfortunate oversight from HP for not including a led for Num Lock button. The touchscreen function failed due to ACPI bug related to a mis-configuration of tables. Sadly, it affects all HP Envy touchscreen series equipped with AMD processors. Workaround made by an Arch user exists and no upstream Linux maintainers has picked up yet for clean up and improvment. The side effect would be an unfortunate false impression HP touchscreen with AMD processors is horrible.The gyroscope needed to automatically rotate the screen depending of the position is broken possibly due to ACPI bug.
On the positive side, I was impressed by the modular adaptability  of HP Envy x360 upgrade wise thanks to the excellent HP documentation. The board can be replaced with the powerful version of Ryzen 7 APU…
