Review of SunFounder Raspberry Pi UPS Power Supply.​

SunFounder’s Raspberry Pi UPS Power Supply is a complete UPS kit for the Raspberry Pi 3/4 Model B/B+ with a PiPower board, a 2,000 mAh battery, and all accessories requires for the assembly. It also works with other Raspberry Pi-sized boards that support 5V DC input such as Banana Pi BPI-M5, Libre Computer ROC-RK3328-CC, and other similar SBCs.

Many years ago, I bought a Raspberry Pi battery pack for review hoping that it would also work as a UPS, but it was not perfect as the board would sometime reboot during power failure simulations. Since then, there have been many UPS kits launched to the market, but I didn’t try any so far, so when SunFounder contacted CNX Software to review their “Raspberry Pi UPS Power Supply”, I took the opportunity, and I will report my finding in this review.

Raspberry Pi UPS Power Supply key features​

• UPS module output – 5V/3A via USB Type-A port
• Battery charge – up to 5V/2A MAX

Jer zna neko nesto o ovome EU - birokrate iz Brisela ili ti trutovi sa pocetnih 20000 odnosno 30000 hiljada eura mesecno okomili se na Open - Source.

The security of all software needs to improve, their is no questioning that, however relying on the EU to decide if your software is secure is not how things should work.

Not even then EU can make un-exploitable software so why should that be asked of anyone else?

Simply put I can see a lot of projects simply refusing to comply and pulling out of the EU as a result, and maybe that will be the kick up the EU lawmakers rears to actually listen to the community who plays the largest roll in international communication systems and the internet, you cannot use the internet without projects like OpenSSL, or, Java, or, HTML5, etc, all projects which are Open-Source and do not have the time or budget to meet the EU's demands, so simply put the EU should according to their own legislation, go dark overnight never to go on the internet ever again, and if that is what has to happen for these clueless snakes to realise who is really in charge then I think it is a worthwhile thing to do, hit the EU so hard that nations start leaving in droves unless they repeal the new regulations.

Debian 13 "Trixie" Aiming To Ship With RISC-V 64-Bit Support​

With today's release of Debian 12 the official ports are for AMD64, AArch64, ARMEL, ARMHF, i386, MIPS, 64-bit MIPS, POWER, and IBM System Z. There isn't RISC-V 64-bit as an official port but that is likely to change for Debian 13.

Debian Developer Jonathan Wiltshire shared an update on the behalf of Debian's release team. Now that Debian 12 has shipped, Debian 13 "Trixie" development will soon open for Debian unstable.

One of the notable comments made in that Debian release team update is that while RISCV64 (RISC-V 64-bit) isn't yet on the official architecture list, the port is making good progress. For the Debian 13 release in a year and a half to two years out, it's expected to ship RISC-V 64-bit support. The architecture qualification will need to happen later in the Debian Trixie cycle.

The release team update can be found on the Debian mailing list. It would have been nice to see RISC-V support with Debian 12 but understandable considering many community open-source developers lack access to performant RISC-V hardware, but by the time of Debian 13 hopefully the RISC-V 64-bit open-source ecosystem will be a lot more mature.

Firefox 116 Enables Video Hardware Acceleration on Raspberry Pi 4​

ll going well, Mozilla Firefox 116 will include hardware accelerated video decoding on the Raspberry Pi 4.

Current stable builds of the famed FOSS browser use software decoding for video playback on the Raspberry Pi 4. While this works it does result in high CPU usage which, if viewing HD and/or high-frame rate content, can result in lag, stuttering, and dropped frames.

Not ideal.

Hardware-accelerated video decoding in Firefox uses VA-API (via FFmpeg) on Linux. This works for traditional computing platforms with traditional graphics cards (Intel, etc) but not the Raspberry Pi.

Thing is, the Raspberry Pi 4 supports hardware accelerated video decoding and encoding, using a Linux kernel API called Video4Linux Memory-to-Memory (V4L2-M2M). Thus, Firefox developers have been working hard to add support for V4L2-M2M to Firefox’s ARM builds.

And now, according to the bug report tracking their effort, it’s ready for roll-out.

Nightly builds of Firefox have had hardware accelerated playback working for h.264 video on the Raspberry Pi 4 for a while. The testing has (presumably) gone well so the feature is being readied for release in Firefox 116, due for release in early August.

It’ll be a while before this feature filters down to Firefox ESR (the version used by the Debian 11-based Raspberry Pi OS). And since there are no pre-compiled nightly builds of Firefox available for ARM, neither I nor you can get an early hands-on to see how well it works.

But I’m super excited this is coming.

I must point out that, for now, this only covers video decode (i.e. playback) but work to extend it to support video encoding is underway.

Also, this is h2.64 only for the moment. Hardware accelerated VP8/VP9 decoding is the next goal and will help bring Firefox’s media capabilities on the Raspberry Pi 4 in-line with other platforms.

Arm: “Panfrost is now the GPU driver for the Linux community”​

Arm is now saying that “in effect, Panfrost is now the GPU driver for the Linux community” after having extended and expanded the collaboration with Collabora for the development of the open-source Panfrost driver for Arm Mali GPUs, following their first official collaboration in the fall of 2020.
Arm goes even as far as to claim that “through the Arm and Collabora partnership, device manufacturers can confidently choose SoCs containing a Mali GPU regardless of the software operating system (OS) and graphics middleware… delivering a high-quality open-source Linux implementation which can be used in their products”. Collabora confirmed the new partnership saying Arm will be instrumental in getting Vulkan support in Panfrost alongside the existing OpenGL and OpenGL ES implementations.
https://cdn.cnx-software.com/wp-con...upports-Panfrost.jpg?lossy=0&strip=none&ssl=1
Going forward that means SBC vendors will have no excuse for not getting 3D graphics acceleration working on Linux with Panfrost when using an Arm SoC with a recent Mali GPU. But it has not always been that way, and the road to a production-ready open-source Arm Mali GPU driver for Linux has been a long and arduous one that basically followed the old adage “first they ignore you, then they laugh at you, then they fight you, then you win”.

The first attempt at an open-source Mali GPU driver was with the Lima project targetting the Mali-400 GPU, and at the time, Arm management was not collaborative and possibly even hostile to the project since it had to reverse-engineer the GPU and related tools. I first learned about the Panfrost open-source driver newer Mali Midgard (Mali-T6xx, Mali-T7xx) GPUs in a 2019 Linaro Connect presentation by Rob Herring, Technical Architect at Linaro, and Tomeu Vizoso, Principal Software Engineer at Collabora.

From there, the future of open-source Arm Mali Linux drivers became more and more hopeful with both Lima and Panfrost being added to Linux 5.2 (July 2019), Arm and Collabora announced a partnership for the development of Panfrost in September 2020, which later left me confused in July 2021 since Alyssa Rosenzweig still had to do reverse-engineering for the Valhall instruction set at that time, Debian 11 was released with both Lima and Panfrost support, and we’ve seen more and more Linux images for Arm SBCs with Panfrost, and I personally tested ODROID-N2+ running Ubuntu 21.10 using Wayland and Panfrost.

Some of the Arm Linux OS images I’ve tested this year relied on the closed-source Mali drivers for 3D graphics acceleration, but I’d expect those to go away, and Panfrost should become the driver of choice in Linux going forward. Android was not mentioned by either Arm or Collobora, so I’d assume Arm will still focus their resources and provide closed-source Mali GPU drivers for Android, while expanding their support for Panfrost on Linux.

Armbian Ubuntu 23.04 can now run on Lenovo X13S Arm laptop.​

The Lenovo X13S Windows 11 Arm laptop based on a Qualcomm Snapdragon 8cx Gen 3 processor can now run Armbian-built Ubuntu 23.04 Lunar images with GNOME or XFCE desktop environment. But before getting too excited note that this is a work-in-progress (WiP) port, so while it’s a nice development, there may be some issues. Let’s have a look at the available information.

When laptop manufacturers started to sell Windows Arm laptops with Qualcomm processors, people wondered whether it would be possible to run Linux on the device, and a community formed around the idea of porting Linux to the Windows Arm laptops, and that gave rise to projects such as Aarch64 laptop. But the latter has not had any activity for a couple of years, and all the supported laptops are only partially supported. But Ricardo Pardini did some work to create an Armbian build for the Lenovo ThinkPad X13S laptop.

This is using grub-with-DTB, @steevdave’s x13s kernel and the @ubuntu “Concept x13s” userspace for Lunar. Performance is stellar. Everything’s done on top of the Armbian UEFI-arm64 support in a single file https://github.com/armbian/build/blob/main/config/boards/thinkpad-x13s.wip. Boot from USB, without Secure Boot. Contribute!

While we don’t know exactly what works and what doesn’t, the screenshot below shows all eight cores are enabled, the display is working along with 3D graphics acceleration using Freedreno open-source driver, battery charging and monitoring look to be working fine too, and so are the laptop’s speakers through ALSA.

The screenshot above shows Linux 6.3.8, but the build script on GitHub has already been updated to the latest Linux 6.4 branch, so the laptop is basically running mainline Linux with some extra patch sets. So it’s unclear what is not working… Previous Linux ports on Windows Arm laptops had mainly issues with 3D graphics acceleration (now taken care of) and support for the cellular modem whose status is unclear in the Armbian images.

If you happen to own a Lenovo X13S Windows 11 Arm laptop, you can download and try out the pre-built Ubuntu 23.04 images, or build them from scratch with the Armbian build script.

Some Of The Features You Will Find Removed With KDE Plasma 6​

Following the recent KDE Akademy developer conference, prominent KDE developer Nate Graham has provided more insight into some of the features being removed with the in-development Plasma 6 desktop.

Among the Plasma features to be removed with version 6.0 include:

- KHotKeys is being removed due to global shortcuts working with KGlobalAccel and KHotKeys not working on Wayland.

- The "windowed widgets" KRunner runner is being dropped.

- The Wayland Force Font DPI and global "icon size" settings are being removed to reduce confusion and simplify how screen UI scaling should be carried out.

- A number of low-quality task switchers are being removed.

- The Air Plasma style is being removed but could be maintained via the KDE Store.

- The per-activity power settings are being removed due to the increase in code complexity for this fragile area of KDE.

- The System Settings Icons view is being removed in favor of the sidebar view.

- Icons in Plasma styles are being removed.

- The Unsplash Picture of the Day is being removed due to Terms of Service changes by Unsplash.

More details on these features being removed with Plasma 6 can be found over on Nate's blog.

On the KDE Wiki is also the official list of features being removed for Plasma 6.

Canonical Announces Real-Time Ubuntu Optimized for Intel Core CPUs.​

Canonical, the company behind the popular Ubuntu Linux distribution, announced today the availability of real-time Ubuntu kernels optimized on Intel Core processors with TSN and TCC support.

Earlier this year in February, Canonical announced the general availability of the real-time Ubuntu kernel for Ubuntu 22.04 LTS (Jammy Jellyfish) users with an Ubuntu Pro subscription. This real-time kernel provides enterprises with end-to-end security and reliability for their time-bound workloads.

Now, Canonical has optimized its Ubuntu RT kernel for Intel silicon, enabling enterprises to harness the power of Linux for a wide range of use cases, including Telco workloads, automation systems for the factory floor, and life-saving medical equipment.

“With the support of optimized Real-time Ubuntu on cutting-edge Intel silicon, enterprises can handle the most demanding workloads,” said Cindy Goldberg, VP of Silicon Alliances at Canonical. “Canonical’s collaboration with Intel allows us to provide a reliable and secure framework for developers and manufacturers, ensuring the longevity and success of their devices in the field.”
With this expansion of the real-time Ubuntu kernel, Canonical addresses the growing need for real-time capabilities among enterprises that want to improve efficiency, optimize operations, and guarantee reliability for their mission-critical systems.


Canonical says that its optimized real-time Ubuntu kernel for Intel SoCs will drive innovation, streamline operations, enhance efficiency, and deliver optimal productivity. The solution is supported on Intel Core processors with Intel Time Coordinated Computing (Intel TCC) and Intel Time Sensitive Networking (TSN).

While Intel TSN support ensures processing and network priority for time-sensitive applications and workloads, Intel TCC support prioritizes access to cache, memory, and networking for real-time workloads.

Since it’s available for the long-term supported Ubuntu 22.04 LTS operating system series, Canonical also promises up to 10 years of package updates for its real-time Ubuntu kernel on Intel processors. To get started with real-time Ubuntu on Intel SoCs, visit the official website.

Cool, the Debian project list RISCV64 as an official architecture! Linux here we go...

riscv64 is now an official architecture

Dear all,

Some of you have been following on IRC, some of you have noticed the
ACCEPTED mails from dak on the mailing list, some of you may have
noticed the recent closure of bug #1033658. For all the others, I am
happy to share the good news:

riscv64 is now an official Debian architecture

If you don't believe it, just have a look at [1]. However before you
rush to update your sources.list file, I want to warn you that the
archive is currently almost empty, and that only the sid and
experimental suites are available. The procedure is to rebootstrap the
port within the official archive, which means we won't import the full
debian-ports archive.

Therefore our next step is to build a minimal set of ~90 source packages
using the debian-ports archive and then import them into the official
archive. These packages will be signed with a special GPG key using
[email protected] as the email address, enabling easy
tracking. This process has already started, hence the few ACCEPTED mails
on the mailing list. It will probably take a few days especially given
that sid is constantly evolving.

Once done, we'll point the build daemons to the official archive. In the
meantime you can just continue to use the debian-ports archive on your
devices.

Regards
Aurelien
