Old bug affecting all HP laptops resolved

With Hans' help, an old bug related to ACPI impacting majority of HP laptops running on any Linux distribution is finally resolved on both kernel 5.4.2 and 5.3.15. Some models may have an odd issue on boot like

hp_wmi: query 0xd returned error 0x5

due to a too small buffer passing in for HPWMI_FEATURE2_QUERY. A fix is on the way for the next update and a test kernel from scratch-build is available (make sure to download first as the scratch build gets erased in a few days).

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-dkms dkms libopencl-amdgpu-pro opencl-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. OpenCL from official AMD driver enabled on Darktable ...

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 ...
