Art of trolling

Reading this post from fedora-devel-list and picked up by OSNews, this is a description of art of trolling. Instead of admitting he screwed his own system, Eric s. Raymod, famous for his Cathedrale of bazar managed to start a flamebait. Bravo!

HP, Linux and ACPI

Majority of HP hardware running on Linux and even Microsoft reported an issue related to a non-standard compliant ACPI. Notable message below repeats at least three times on the boot:


4.876549] ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D128] at bit offset/length 128/1024 exceeds size of target Buffer (160 bits) (20190215/dsopcode-198) 
[ 4.876555] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529) 
[ 4.876562] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529)


The bug is a known for years from which Linux kernel team are unable to fix without the help of vendor i.e. HP. Here is a compilation of reports:
BIOS error: The BIOS in this system is not fully ACPI compliant. ACPI BIOS ERROR (blue screen) on startup ACPI bad works with Linux  The good news is some errors seems harmless. Unfortunately, such errors displayed the quirks approach used by vendors to support …

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-installamdgpu-pro-install symlink to amdgpudoc folderrepodata folderRPMS 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 cli…

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…
