Yay, finally all the pieces have come together and I have finally been able to compile Qt 6.9 and @kde Plasma development version (what is to be released as 6.4 in June) for my @bananapi BPI-F3, a RISC-V single-board (mini) computer. Plasma does start and run, but looks like QML/QtQuick applications (which includes the desktop itself) have rendering problems 😞 Qt Widget apps render/run just fine. Now to figure out where the problem is…

#Linux #KDE #KDEPlasma #RISCV #RISC_V #Qt6 #QML #QtQuick

@JRepin @kde @bananapi@mastodon.social do we (kde as a whole) need to get you more risc-v compile power? we have it, in boxes and in pieces.

@kdedude @kde Re: compilation, depends on how much faster the HW available is. I have distributed cross-compilation set up so the bottleneck right now is the linking/LTO/... which is not distributed and done on BPI-F3 only, and quite slow. Not sure if other RISC-V CPU would be faster. Maybe SiFive P550 or Sophgo SG2042/C920.

But I'm thinking of profiling Qt, Plasma, KDE apps and trying to do some assembler-optimising slow parts and testing changes on different CPUs would be useful/beneficial.
