Context: Fedora/Bazzite/Kinoite/universal-blue/KDE/Flatpacks
When using KDE applications (like Okular or Gwenview) installed as Flatpaks in Fedora KDE Bazzite or other containerized Linux distributions, they may fail to open remote files (like those on Samba shares) when launched from Dolphin File Explorer.
Example error from Okular:
Could not open smb://... Reason: Unable to create KIO worker. Unknown protocol 'smb'.

This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.
It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.
Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2
The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and
