And some more #Linux thoughts on the absolute ass drama about removing 32 bit libs, I have a #ARM PC and it's CPU is only 64 bits, same goes for my #RISC_V machine, there 32 bit outright does not exist.

AMD and Intel play already with the idea of removing their 32 Bit legacy which would make their CPUs more efficient and also likely remove a few possible attack vectors.

So it's a valid thing to finally talk about the whole topic, remove some legacy crust and find a solution to keep 32 bit software going that can't move on.

The person behind Lutris had also some thoughts that should be considered:

fosstodon.org/@lutris/11476951

FosstodonLutris (@lutris@fosstodon.org)Linux distros are going to keep on trying to remove their 32bit stack and it's only a matter of time before 32bit gets removed from every major distro. We could have a compatibility layer like Wine, but it may be better to have a full blown emulator given how many components need to be replaced: - i686 -> x86_64 or Arm64 - X11 -> Wayland - OpenGL -> Vulkan - Alsa / OSS -> Pipewire - Old GlibC -> new GlibC etc... While this seems a very daunting task, it should be technically possible

Looks like no one is yet talking about it, but a Chinese company called #UltraRISC is about to release new #RISCV #RISC_V CPU called #UR_DP1000 that looks extremely interesting and could maybe be the first RISC-V CPU that could be used as daily driver.

Only small biter I see sadly no RVV 1.0 vector unit, that would have been the icing on the cake, I strongly hope though that #OpenKylin and #Deepin support it well when it's out, OS support for my Megrez is terrible...

Little reminder we have no algorithm here, Favourites are just a little head pat, to got things out YOU NEED to Boost things to get them around, also one or two important tags help, I am looking at you #Furry I wont find your #FurryArt otherwise, or many other cool topics like #RISCV #RISC_V just sayin...

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:

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…

"We’re happy to share that DeepComputing’s DC-ROMA RISC-V Mainboard for Framework Laptop 13 is now in stock and shipping in the Framework Marketplace. This is very much a developer-focused board to help accelerate maturing the software ecosystem around RISC-V."

@zygoon @frameworkcomputer I have tried out the #RISC_V board directly on the #Ubuntu booth on #FOSDEM but while running a system update on the pre-installed Ubuntu 24.04 LTS, it ran out of storage space.

So I want to replace its storage by a more spacious one.

Zyga, what kind of storage and which size are you using? Mine came with a micro-SD card, I am not sure about the size, can be that it is only 8 GB or so.

Anyone can give me recommendations about which storage to use?

"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…

🧵 1/n

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.
