A Fedora Core 5 i386 on Athlon64 3200+

Writing this blog on a brand new motherboard Gibabyte GA-K8NSC-939 with Athlon64 3200+ Venice. It is much snappier than the old Athlon XP2500+ Barton. That motherboard is not equipped with on-board which is not a big deal. That costs $310 CAN which is a bargain for its category. I am planning to get a SATA hard drive to install x86_64 rawhide version of Fedora Core this.

En passant, je salue la communauté de Fedora France.

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…

Improving HP Envy x360 convertible on Linux: the missing accelerometer driver

If you own an HP laptop equipped with AMD processor, you may find out the auto-rotation will not work as intended. It turned out that sensor is missing a driver not currently available on Linux kernel using the lspci -nn command from the terminal

03:00.7 Non-VGA unclassified device [0000]: Advanced Micro Devices, Inc. [AMD] Device [1022:15e4] That driver in question is AMD Sensor Fusion HUB. Unfortunately, researching it turned out harder even on AMD own website. Bug is already filed without answer yet from one of AMD representative.

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…
