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…

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…

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.

Running HP Envy x360 Ryzen 2500U with SSD

Replacing the 1TB 7200rpm HDD with a well reviewed  Samsung 860 EVO 1TB HDD turned out a drastic improvement in term of speed caught me by surprise.

Noticeable effect was the nearly five seconds boot straight to the login screen and the response time of opening and closing applications. Envy x360 Ryzen 5 feels snappy now.

On a side note, Windows 10 has a nice app called Windows Hello to authenticate with face similar to facial recognition founds on Android device. A similar open source application called howdy is available but not packaged for Fedora yet.

Retiring ASUS X550ZE and greeting HP Envy x360 Ryzen 5

My ASUS X550ZE reached its end of life due to hardware power issue after getting a lot of abuse. From that experience, I have learned a lot about dual Radeon graphic processors working in the open source world and I followed AMD graphic development since then.

Enter HP Envy x360 Convertible 15-cp0xxx Ryzen 5 marking the return to tablet PC. I originally intended to buy the Ryzen 7 version for more performance but the specification is very similar with only a sightly more powerful graphic processor as the difference on Ryzen 5. The model uses a 1 TB hard disk drive with 8 GB DDR4 RAM and I plan to upgrade to a 1TB solid state drive (Samsung Evo version looks suitable).

Installation  Installing Fedora 29 Beta Design Suite was very smooth after shrinking the partition of Windows 10 and keeping Secure Boot enabled by default.

Post installation  Some revealing issues:
Touchscreen and stylus mode is broken due to acpi bug preventing proper detection.AMD Raven, the name of the APU, works fin…
