#risc_v

A couple of days ago a new release 6.14 of KDE Frameworks came out and part of it is the syntax highlighting engine, used not only by KDE applications like Kate and KDevelop; but also by some others like Qt Creator.

I'm happy to report that this version also brings support for RISC-V instructions/registers/… in GNU Assembler, that I contributed:
🔗 invent.kde.org/frameworks/synt

#RISCV #RISC_V #assembler #assembly #programming #Kate #editor #KDevelop #QtCreator #Qt6 #IDE #KDE #KDEFrameworks @kde

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…

@frameworkcomputer @zygoon #DeepComputing has published an update of the #Ubuntu 24.04 image (vers. 1.1)!

It fixes most of my complaints, and of Zyga, too:
- #Snap works now! Kernels supports squashfs, I could install snapd, snapcraft and rockcraft, but did not find any app Snap for #RISC_V. Seems I have to start with the #OpenPrinting Snaps ...
- There are 2 Browsers, #Firefox, and #Chromium on it, DEB packages
- Standard Ubuntu GNOME layout, launcher on the left

Inside SiFive’s P550 Microarchitecture
🔗 old.chipsandcheese.com/2025/01

"The P550 is a 3-wide out-of-order core with a 13 stage pipeline. Out-of-order execution lets the core move past a stalled instruction to extract instruction level parallelism. It’s critical for achieving high performance because cache and memory latency can be significant limiters for modern CPUs."

At last I got that final but important piece for my RISC-V SBC ( @bananapi BPI-F3): the cooler. Now I can finally start compiling some big chunks of code like Qt and KDE software. I do have distributed cross-compiling set up using Icecream, but apparently you can't prevent it scheduling compile jobs locally on SBC and only send them to more powerful computers. Let the fun begin…

Just got some RISC-V hardware goodies to play with in the following days/months: BPI-F3 SBC by @bananapi with SpacemiT K1 8-core CPU supporting RVV 1.0 vector extensions. Hooked it up to the TV, booted it for the first time from a microSD with the default Bianbu GNU/Linux distro, so far so good. Will try to get Gentoo or openSUSE Tumbleweed with KDE Plasma/software running next.

RISC-V Vector Extension overview
🔗 0x80.pl/notesen/2024-11-09-ris

"The goal of this text is to provide an overview of RISC-V Vector extension (RVV), and compare — when applicable — with widespread SIMD vector instruction sets: SSE, AVX, AVX-512, ARM Neon and SVE.
[…]
The vector extension is quite a huge addition. It adds 302 instructions plus four highly configurable load & store operations."

I had a blast at #RDevDay! I had wonderful pair programming session initiated by Jane He (who is working to get #RStats to compile on #risc_v architecture). We sent a patch to propose a fix of an old bug in `R CMD build`.

Huge thanks to @HeathrTurnr and @R_Contributors for making this happen! It’s great to know that contributing to R core doesn’t have to be scary.

@phoronix Don't make a RISC-V laptop. We would have no idea how the display, keyboard, support, parts availability, serviceability, etc are going to be.

Instead, make a RISC-V motherboard designed to drop into a @frameworkcomputer laptop. The specs are entirely open. Then everything else becomes a known quantity, the upgrade path becomes cheaper, and the buyer's risk is lower. (It could also be used as a single-board computer with the available case.)
