System76's Open Firmware 'Re-Disables' Intel's Management Engine (phoronix.com) 19

Linux computer vendor System76 shared some news in a recent blog post. "We prefer to disable the Intel Management Engine wherever possible to reduce the amount of closed firmware running on System76 hardware. We've resolved a coreboot bug that allows the Intel ME (Management Engine) to once again be disabled."

Phoronix reports that the move will "benefit their latest Intel Core 13th Gen 'Raptor Lake' wares as well as prior generation devices." Intel ME is disabled for their latest Raptor lake laptops and most older platforms with some exceptions like where having a silicon issue with Tiger Lake. System76 has also added a new firmware setup menu option for enabling/disabling UEFI Secure Boot. The motivation here with making it easier to toggle Secure Boot is for allowing Windows 11 support with SB active while running System76 Open Firmware.

Red Hat is Dropping Its Support for LibreOffice (lwn.net) 141

The Red Hat Package Managers for LibreOffice "have recently been orphaned," according to a post by Red Hat manager Matthias Clasen on the "LibreOffice packages" mailing list, "and I thought it would be good to explain the reasons behind this." The Red Hat Display Systems team (the team behind most of Red Hat's desktop efforts) has maintained the LibreOffice packages in Fedora for years as part of our work to support LibreOffice for Red Hat Enterprise Linux. We are adjusting our engineering priorities for RHEL for Workstations and focusing on gaps in Wayland, building out HDR support, building out what's needed for color-sensitive work, and a host of other refinements required by Workstation users. This is work that will improve the workstation experience for Fedora as well as RHEL users, and which, we hope, will be positively received by the entire Linux community.

The tradeoff is that we are pivoting away from work we had been doing on desktop applications and will cease shipping LibreOffice as part of RHEL starting in a future RHEL version. This also limits our ability to maintain it in future versions of Fedora.

We will continue to maintain LibreOffice in currently supported versions of RHEL (RHEL 7, 8 and 9) with needed CVEs and similar for the lifetime of those releases (as published on the Red Hat website). As part of that, the engineers doing that work will contribute some fixes upstream to ensure LibreOffice works better as a Flatpak, which we expect to be the way that most people consume LibreOffice in the long term.

Any community member is of course free to take over maintenance, both for the RPMs [Red Hat Package Managers] in Fedora and the Fedora LibreOffice Flatpak, but be aware that this is a sizable block of packages and dependencies and a significant amount of work to keep up with.

Commenters on LWN.net are now debating its impact.

One pointed out that "You will still find it in GNOME Software, which will install a Flatpak from FlatHub rather than an RPM from the distro."

Ubuntu Core as an immutable Linux Desktop base (ubuntu.com) 71

motang writes: Canonical, the sponsor of widely popular Ubuntu Linux, plans on shipping the next LTS in two versions. In addition to the traditional version, there will be one immutable desktop OS flavor. From Canonical blog: The technology behind snaps extends beyond the distribution of desktop applications however. With Ubuntu Core this philosophy of security and stability applies equally to the components that make up the entire Ubuntu operating system. Rather than treating the OS as a single immutable 'blob,' Ubuntu Core breaks it up into discrete components. The base of Ubuntu Core, for example, is built on four primary snaps:

Gadget: Defines the system's bootloader, partition layout and default configurations for snaps.
Kernel: Containing the Linux kernel and hardware drivers.
Base: A minimal Ubuntu OS image containing only the necessary services and utilities to support the applications running on top.
Snapd: Manages the lifecycle of all snaps in an Ubuntu Core system.
Additional OS snaps can then be layered onto this image to enable other elements of the operating system such as a desktop environment.

Red Hat's Layoffs Included Fedora Program Manager (funnelfiasco.com) 71

When Red Hat laid off 4% of its global staff, Fedora Program Manager Ben Cotton was "a member of that 4%," according to a new post on Cotton's blog: I've received so much support from people since the news started spreading. It's like that end scene of "It's a Wonderful Life" and I'm George Bailey. I'm proud of the contributions I've made to the Fedora community over the last five years, and it feels good to have others recognize that.
Cotton joined Red Hat in 2018, but "I was a Fedora contributor long before" Cotton writes, adding later that "I fully intend to still be participating in the Fedora community when my account hits the 20-year mark in May 2029." (Cotton's first foray into Fedora was joining its Docs team in 2009, and then volunteering to be the Docs project leader in 2011...)

And the blog post adds that professionally Cotton is "already pursuing a few opportunities... In the meantime, I have (at least) a few weeks to relax for a bit." I've told folks that if Fedora falls off the rails, then I have failed. I'm working with Matthew, Justin, and others to ensure coverage of the core job duties one way or another. I've worked hard over the years to automate tasks that can be automated. The documentation is far more comprehensive than what I inherited. No doubt there are gaps in what I've left for my successors. However, my goal is that in a few months, nobody will notice that I'm gone. That's my measure of success...

As to what the broader implication behind the loss of my position might be, I don't know. There's no indication that my role was targeted specifically. There are definitely people in Red Hat who continue to view Fedora as strategically important.

Despite Layoffs, Open Source and Linux Skills are Still in Demand (zdnet.com) 36

ZDNet reports that Jim Zemlin, executive director at the Linux Foundation, recently noted rounds of tech-industry layoffs "in the name of cost-cutting." But then Zemlin added that "open source is countercyclical to these trends. The Linux Foundation itself, for instance, had its best first quarter ever."

As Hilary Carter, SVP of research and communications at the Linux Foundation, said in her keynote speech at Open Source Summit North America in Vancouver, Canada: "In spite of what the headlines are saying, the facts are 57% of organizations are adding workers this year." Carter was quoting figures from the Linux Foundation's latest job survey, which was released at the event.

Other research also points to brighter signs in tech employment trends. CompTIA's recent analysis of the latest Bureau of Labor Statistics (BLS) data suggests the tech unemployment rate climbed by just 2.3% in April. In fact, more organizations plan to increase their technical staff levels rather than decrease.

The demand for skilled tech talent remains strong, particularly in fast-developing areas, such as cloud and containers, cybersecurity, and artificial intelligence and machine learning. So, what do these all areas of technology have in common? The answer is they're all heavily dependent on open source and Linux technologies.

While layoffs are happening at Microsoft, Amazon, Google, IBM, and even Red Hat, "the Linux Foundation found senior technical roles are seeing the biggest cuts," the article points out. "New hiring is focused on developers and IT managers." And companies are also spending more on training for existing technical staff, "driven by the fact that there aren't enough experts in hot technologies, such as Kubernetes and generative AI, to go around." Interestingly, a college degree is no longer seen as such a huge benefit. Businesses responding to the Linux Foundation's research felt upskilling (91%) and certifications (77%) are more important than a university education (58%) when it comes to addressing technology needs.

Goodbye To Roblox On Linux With Their New Anti-Cheat and Wine Blocking (gamingonlinux.com) 97

Roblox's new anti-cheat software puts a stop to in-game exploits, but at what cost? According to Liam Dawe from Gaming On Linux, it's blocking the Wine application, meaning "you won't be able to play it on Linux any more, at all, unless you find some sort of special workaround." He adds: "Previously the roll-out of this update was being tested only with some users. Now though it's here for everyone giving a 64 bit client and introducing their Hyperion anti-cheat software which they are intentionally blocking Wine with." Here's what one of their staff had to say about this: Hi - thanks for the question. I definitely get where you're coming from, and as you point out, you deserve a clear, good-faith answer. Unfortunately that answer is essentially "no."

From a personal perspective, a lot of people at Roblox would love to support Linux (including me). Practically speaking, there's just no way for us to justify it. If we release a client, we have to support it, which means QA, CS, documentation, etc., all of which is much more difficult on a fragmented platform. We release weekly on a half-dozen platforms. Adding in the time to test, debug, and release a Linux client would be expensive, which means time taken away from improving Roblox on our current platforms.

Even Wine support is difficult because of anti-cheat. As wonderful as it would be to allow Roblox under Wine, the number of users who would take advantage of that is minuscule compared with our other platforms, and it's not worthwhile if it makes it easy for exploiters to cheat.

I'm sorry to be such a downer about this, but it's the reality. We have to spend our time porting to and supporting the platforms that will grow our community.

Again, I'm personally sorry to have to say this. Way back in 2000 I had a few patches accepted into the kernel, and I led the port of Roblox game servers from Windows to Linux several years ago. From a technical and philosophical perspective, it would be a wonderful thing to do. But our first responsibility is to our overall community, and the opportunity cost of supporting a Linux client is far, far too high to justify.

Linus Torvalds Cleaned Up the Intel LAM Code for Linux 6.4 (phoronix.com) 27

Last week Linus Torvalds personally cleaned up the x86 memory copy code for Linux 6.4, Phoronix reports — and this week "he's merged more of his own code as he took issue with some of the code merged by Intel engineers as part of their Linear Address Masking enabling." Back during the Linux 6.2 days at the end of last year, Linus rejected the Intel LAM code at the time for various technical issues. Intel then reworked it for Linux 6.4. This time around Linus merged Intel LAM into Linux 6.4 as this new CPU feature for letting user-space store metadata within some bits of pointers without masking it out before use. Intel LAM — like Arm TBI — can be of use to virtual machines, profiling / sanitizers / tagging, and other applications. But this time around there were some less than ideal code that he personally took to sprucing up...

Torvalds reworked around one hundred lines of code for cleaning it up.

It's fun to read Torvalds' commit messages (included in both Phoronix articles). Torvalds begins by writing that the LAM updates "made me unhappy about how 'access_ok()' was done, and it actually turned out to have a couple of small bugs in it too..."

'sudo' and 'su' Are Being Rewritten In Rust For Memory Safety (phoronix.com) 143

Phoronix reports: With the financial backing of Amazon Web Services, sudo and su are being rewritten in the Rust programming language in order to increase the memory safety for the widely relied upon software... to further enhance Linux/open-source security.
"[B]ecause it's written in C, sudo has experienced many vulnerabilities related to memory safety issues," according to a blog post announcing the project: It's important that we secure our most critical software, particularly from memory safety vulnerabilities. It's hard to imagine software that's much more critical than sudo and su.

This work is being done by a joint team from Ferrous Systems and Tweede Golf with generous support from Amazon Web Services. The work plan is viewable here. The GitHub repository is here.

Red Hat's 30th Anniversary: How a Microsoft Competitor Rose from an Apartment-Based Startup (msn.com) 47

For Red Hat's 30th anniversary, North Carolina's News & Observer newspaper ran a special four-part series of articles.

In the first article Red Hat co-founder Bob Young remembers Red Hat's first big breakthrough: winning InfoWorld's "OS of the Year" award in 1998 — at a time when Microsoft's Windows controlled 85% of the market. "How is that possible," Young said, "that one of the world's biggest technology companies, on this strategically critical product, loses the product of the year to a company with 50 employees in the tobacco fields of North Carolina?" The answer, he would tell the many reporters who suddenly wanted to learn about his upstart company, strikes at "the beauty" of open-source software.

"Our engineering team is an order of magnitude bigger than Microsoft's engineering team on Windows, and I don't really care how many people they have," Young would say. "Like they may have thousands of the smartest operating system engineers that they could scour the planet for, and we had 10,000 engineers by comparison...."

Young was a 40-year-old Canadian computer equipment salesperson with a software catalog when he noticed what Marc Ewing was doing. [Ewing was a recent college graduate bored with his two-month job at IBM, selling customized Linux as a side hustle.] It's pretty primitive, but it's going in the right direction, Young thought. He began reselling Ewing's Red Hat product. Eventually, he called Ewing, and the two met at a tech conference in New York City. "I needed a product, and Marc needed some marketing help," said Young, who was living in Connecticut at the time. "So we put our two little businesses together."

Red Hat incorporated in March 1993, with the earliest employees operating the nascent business out of Ewing's Durham apartment. Eventually, the landlord discovered what they were doing and kicked them out.

The four articles capture the highlights. ("A visual effects group used its Linux 4.1 to design parts of the 1997 film Titanic.") And it doesn't leave out Red Hat's skirmishes with Microsoft. ("Microsoft was owned by the richest person in the world. Red Hat engineers were still linking servers together with extension cords. ") "We were changing the industry and a lot of companies were mad at us," says Michael Ferris, Red Hat's VP of corporate development/strategy. Soon there were corporate partnerships with Netscape, Intel, Hewlett-Packard, Compaq, Dell, and IBM — and when Red Hat finally goes public in 1999, its stock sees the eighth-largest first-day gain in Wall Street history, rising in value in days to over $7 billion and "making overnight millionaires of its earliest employees."

But there's also inspiring details like the quote painted on the wall of Red Hat's headquarters in Durham: "Every revolution was first a thought in one man's mind; and when the same thought occurs to another man, it is the key to that era..." It's fun to see the story told by a local newspaper, with subheadings like "It started with a student from Finland" and "Red Hat takes on the Microsoft Goliath."

Something I'd never thought of. 2001's 9/11 terrorist attack on the World Trade Center "destroyed the principal data centers of many Wall Street investment banks, which were housed in the twin towers. With their computers wiped out, financial institutions had to choose whether to rebuild with standard proprietary software or the emergent open source. Many picked the latter." And by the mid-2000s, "Red Hat was the world's largest provider of Linux...' according to part two of the series. "Soon, Red Hat was servicing more than 90% of Fortune 500 companies." By then, even the most vehement former critics were amenable to Red Hat's kind of software. Microsoft had begun to integrate open source into its core operations. "Microsoft was on the wrong side of history when open source exploded at the beginning of the century, and I can say that about me personally," Microsoft President Brad Smith later said.

In the 2010s, "open source has won" became a popular tagline among programmers. After years of fighting for legitimacy, former Red Hat executives said victory felt good. "There was never gloating," Tiemann said.

"But there was always pride."

In 2017 Red Hat's CEO answered questions from Slashdot's readers.

System76 Plans Its Own Open Hardware Laptop, and a New Desktop Environment Written in Rust (linux-magazine.com) 47

Linux Magazine argues that System76's Pop!_OS offers "something rare: a commercial distribution that was integrated into the hardware, with utilities designed specifically for System76 computers and keyboards." The only other example of an integrated commercial distro of which I am aware is Purism, a company in the same niche... With hardware and software coming from the same source — what business calls vertical integration — distributions like System76/Pop!_OS offer Linux users their first experiences with what Windows and macOS users have always enjoyed — to say nothing of the closest they can currently get to open hardware. Could Linux be finally becoming mainstream at last?
They interviewed System76 CEO Carl Richell (along with a marketing director and media relations manager), who remembered how System76 was actually founded in Carl's basement around 2005: He wanted to show the world how far Linux and open source software had come by delivering it preinstalled on high-quality computers backed by caring, knowledgeable customer support. Carl felt that making Linux computers that highlight the work of the community would be a great way to introduce the broader public to open source technology and its potential...

LM: What other hardware might System76 offer in the future?

S76: We are in the research and development process of designing our own in-house laptop. We'll eventually refresh our Meerkat mini desktop with a new Thelio-style aesthetic. That project will start sometime after our first in-house laptops start shipping. [In addition,] Launch keyboards and the System76 Keyboard Configurator work on macOS and Windows! We've also prepared ISO layouts for most Launch models but don't have a time frame for release.

LM: What are you willing to say at this point about the company's future directions?

S76: We're developing COSMIC DE — a desktop environment written in Rust — as well as a prototype for an open hardware laptop manufactured in-house. Finally, Nebula, a line of computer cases based on Thelio desktops will be arriving in the coming months.

My favorite line from the interview? "Seeing a flat sheet of aluminum transformed into a beautiful desktop is strikingly rewarding."

New Intel Linux Graphics Driver Patches Released, Up To 10-15% Better Performance (phoronix.com) 7

A new set of patches have been released for the Intel Linux graphics driver that "can provide 10-15% better performance when operating in the tuned mode," reports Phoronix. From the report: The set of Intel i915 Linux kernel graphics driver patches are about exposing the Intel RPS (Requested Power State) up/down thresholds. Right now the Intel Linux kernel driver has static values set for the up/down thresholds between power states while these patches would make them dynamically configurable by user-space. Google engineer Syed Faaiz Hussain raised the issue that they experimented with the Intel RPS tuning and were able to manage up to 15% better performance. With Counter-Strike: Global Offensive with OpenGL was a 14.5% boost, CS:GO with Vulkan was 12.9% faster, and Civilization VI with OpenGL was 11% faster while Strange Brigade was unchanged. No other game numbers were provided.

But as this is about changing the threshold for how aggressively the Intel graphics hardware switches power states, the proposed patches leave it up to user-space to adjust the thresholds as they wish. Google engineers are interested in hooking this into Feral's GameMode so that the values could be automatically tuned when launching games and then returning to their former state when done gaming, in order to maximize battery life / power efficiency. The only downside with these current patches are that they work only for non-GuC based platforms... So the latest Alder/Raptor Lake notebooks as well as Intel DG2/Alchemist discrete graphics currently aren't able to make use of this tuning option.

Linux Kernel 6.3 Released (zdnet.com) 16

An anonymous reader quotes a report from ZDNet, written by Steven Vaughan-Nichols: The latest Linux kernel is out with a slew of new features -- and, for once, this release has been nice and easy. [...] Speaking of Rust, everyone's favorite memory-safe language, the new kernel comes with user-mode Linux support for Rust code. Miguel Ojeda, the Linux kernel developer, who's led the efforts to bring Rust to Linux, said the additions mean we're, "getting closer to a point where the first Rust modules can be upstreamed."

Other features in the Linux 6.3 kernel include support and enablement for upcoming and yet-to-be-released Intel and AMD CPUs and graphics hardware. While these updates will primarily benefit future hardware, several changes in this release directly impact today's users' day-to-day experience. The kernel now supports AMD's automatic Indirect Branch Restricted Speculation (IBRS) feature for Spectre mitigation, providing a less performance-intensive alternative to the retpoline speculative execution.

Linux 6.3 also includes new power management drivers for ARM and RISC-V architectures. RISC-V has gained support for accelerated string functions via the Zbb bit manipulation extension, while ARM received support for scalable matrix extension 2 instructions. For filesystems, Linux 6.3 brings AES-SHA2-based encryption support for NFS, optimizations for EXT4 direct I/O performance, low-latency decompression for EROFS, and a faster Brtfs file-system driver. Bottom line: many file operations will be a bit more secure and faster.

For gamers, the new kernel provides a native Steam Deck controller interface in HID. It also includes compatibility for the Logitech G923 Xbox edition racing wheel and improvements to the 8BitDo Pro 2 wired game controllers. Who says you can't game on Linux? Single-board computers, such as BannaPi R3, BPI-M2 Pro, and Orange Pi R1 Plus, also benefit from updated drivers in this release. There's also support for more Wi-Fi adapters and chipsets. These include: Realtek RTL8188EU Wi-Fi adapter support; Qualcomm Wi-Fi 7 wireless chipset support; and Ethernet support for NVIDIA BlueField 3 DPU. For users dealing with complex networks that have both old-school and modern networks, the new kernel can also handle multi-path TCP handling mixed flows with IPv4 and IPv6.
Linux 6.3 is available from kernel.org. You can learn how to compile the Linux kernel yourself here.

Red Hat Begins Cutting 'Hundreds of Jobs' (phoronix.com) 49

According to Phoronix citing multiple local North Carolina news outlets, Red Hat is cutting "hundreds of jobs" in an initial round of layoffs announced today. From the report: According to WRAL, Red Hat CEO Matt Hicks is said to have told employees in an email "we will not reduce roles directly selling to customers or building our products," which is hopefully good news for their many upstream Linux developers they employ that ultimately build Red Hat Enterprise Linux and associated software products. Red Hat will begin notifying affected employees today in some countries while the process will continue through the end of the quarter. IBM, which acquired Red Hat in 2019, has already slashed some five thousand positions so far in 2023.

Linux Foundation Launches New Organization To Maintain TLA+ (techcrunch.com) 16

The Linux Foundation, the nonprofit tech consortium that manages various open source efforts, today announced the launch of the TLA+ Foundation to promote the adoption and development of the TLA+ programming language. AWS, Oracle and Microsoft are among the inaugural members. From a report: What is the TLA+ programming language, you ask? It's a formal "spec" language developed by computer scientist and mathematician Leslie Lamport. Best known for his seminal work in distributed systems, Lamport -- now a scientist at Microsoft Research -- created TLA+ to design, model, document and verify software programs -- particularly those of the concurrent and distributed variety.

To give a few examples, ElasticSearch, the organization behind the search engine of the same name, used TLA+ to verify the correctness of their distributed systems algorithms. Elsewhere, Thales, the electrical systems manufacturing firm, used TLA+ to model and develop fault-tolerant modules for its industrial control platform. "TLA+ is unique in that it's intended for specifying a system, rather than for implementing software," a Linux Foundation spokesperson told TechCrunch via email. "Based on mathematical concepts, notably set theory and temporal logic, TLA+ allows for the expression of a system's desired correctness properties in a formal and rigorous manner."

New Spectre-Related 'Medium Severity' Flaw Patched in Linux Kernel (theregister.com) 11

"The Spectre vulnerability that has haunted hardware and software makers since 2018 continues to defy efforts to bury it," reports the Register: On Thursday, Eduardo (sirdarckcat) Vela Nava, from Google's product security response team, disclosed a Spectre-related flaw in version 6.2 of the Linux kernel. The bug, designated medium severity, was initially reported to cloud service providers — those most likely to be affected — on December 31, 2022, and was patched in Linux on February 27, 2023.

"The kernel failed to protect applications that attempted to protect against Spectre v2, leaving them open to attack from other processes running on the same physical core in another hyperthread," the vulnerability disclosure explains. The consequence of that attack is potential information exposure (e.g., leaked private keys) through this pernicous problem....

Spectre v2 — the variant implicated in this particular vulnerability — relies on timing side-channels to measure the misprediction rates of indirect branch prediction in order to infer the contents of protected memory. That's far from optimal in a cloud environment with shared hardware... The bug hunters who identified the issue found that Linux userspace processes to defend against Spectre v2 didn't work on VMs of "at least one major cloud provider."

Biggest Linux Company of Them All Still Pushing To Become Cloud Power (theregister.com) 23

An anonymous reader shares a report: For Red Hat, which turned 30 on March 27, it was a cause for celebration. From a business that got started in one of its co-founder's wife's sewing room, it became the first billion-dollar pure-play open-source company and then the engine driving IBM. It has been a long strange trip. Sure, today, the tech world is dominated by Linux and open source software, but in 1993, Linux was merely an obscure operating system known only to enthusiasts. Red Hat played a significant role in transforming the "just a hobby" operating system into today's major IT powerhouse. Red Hat co-founder Bob Young, who previously ran a rental typewriter business, was one of those who became intrigued by Linux. In 1993, he established ACC Corporation, a catalog company that distributed Slackware Linux CDs and open-source software.

[...] In 2003, Paul Cormier, then Red Hat's vice president of engineering and now the company's chairman, spearheaded the shift from the inexpensive prosumer Red Hat Linux distribution to the full business-oriented Red Hat Enterprise Linux (RHEL). At the time, many Linux users hated the idea. Even inside Red Hat, Cormier said that many engineers were initially opposed to the new business model, causing some to leave the company while others stayed. The change also upset many users who felt Red Hat was abandoning its original customers. However, enterprise clients had a different perspective. Whitehurst, who became Red Hat CEO in 2008, said, "Once RHEL was in the market, we had to fully support it to make it truly consumable for the enterprise." They succeeded, and Red Hat continued to grow. This is the model that turned Red Hat into the first billion-dollar-a-quarter pure open-source company. Impressive for a business built around an operating system once considered suitable only for the "lunatic fringe." Then, in 2018, IBM acquired Red Hat for a cool $34 billion. There was nothing crazy about that move.

[...] Another change that was already present in Red Hat, a shift towards supporting the cloud, has accelerated. Today, while RHEL remains the heart of the business, the Linux-powered cloud has become increasingly important. In particular, Red Hat OpenShift, its Kubernetes-powered hybrid cloud application platform, is more important than ever. Where does Red Hat go from here? When I last talked to Cormier and Red Hat's latest CEO, Matt Hicks, they told me that they'd keep moving forward with the hybrid cloud. After all, as Cormier pointed out, "the cloud wouldn't be here" without Linux and open source. As for Red Hat's relationship with IBM, Cormier said, "The red lines were red, and the blue lines were blue, and that will stay the same."

Linux 6.4 Bringing Apple M2 Additions For 2022 MacBook Air, MacBook Pro, Mac Mini (phoronix.com) 37

Further adding to the excitement of the upcoming Linux 6.4 merge window is the mainline kernel seeing the Device Tree (DT) additions for Apple's current M2 devices including the MacBook Air, MacBook Pro, and Mac Mini systems. From a report: The upstream kernel still has more work to go around the M1/M2 support compared to the downstream state with Asahi Linux, but at least now with this DT support will provide some basic level of upstream kernel support for the Apple M2. Asahi Linux lead developer Hector Martin today sent in the Apple SoC DT updates targeting the Linux 6.4 cycle for queuing into the SoC tree ahead of the merge window opening around the end of the month. The main addition with this pull request is adding the Apple M2 Device Tree series.

Star64 RISC-V Single-Board PC Launches April 4 for $70 and Up (pine64.org) 26

PINE64 has an update about their Star64 single-board computer with a quad-core RISC-V processor: it will be available on April 4th in two configurations: 4GB and 8GB LPDDR4 memory for $69.99 and $89.99: Let me just quickly reiterate the Star64 features:


- Quad core 64bit RISC-V
- HDMI video output
- 4x DSI and 4x CSI lates
- i2c touch panel connector
- dual Gigabit Ethernet ports
- dual-band WiFi and Bluetooth
- 1x native USB3.0 port, 3x shared USB2.0 ports
- PCIe x1 open-ended slot and GPIO bus pins (i2c, SPI and UART).
- The board also features 128M QSPI flash and eMMC and microSD card slots.


The board will be available in two different RAM configurations — with 4GB and 8GB LPDDR4 memory for $69.99 and $89.99 respectively. The Star64 store page ought to already be live when you read this, but will be listed as out of stock until the 4th.

Liliputing offers this summary: The Star64 is a single-board computer with a quad-core RISC-V processor, support for up to 8GB of RAM and up to 128GB of storage (as well as a microSD card reader). Developed by the folks at Pine64, it's designed to be an affordable platform for developers and hobbyists looking to get started with RISC-V architecture. Pine64 first announced it was working on the Star64 last summer...
Meanwhile, PINE64's Linux tablets, the PineTab2 and PineTab-V, will launch one week later on Tuesday, April 11th.

Other highlights from this month's community update: there's now a dedicated Debian with GNOME image with tailored settings for grayscale for their Linux-based "PineNote" e-ink tablets. ("Other OSes and desktop environments are being worked on too.")

And the update also includes photos of one user's cool 3D-printed replacement cases for their PinePhone featuring Tux the penguin.
