Nearly four years after its last major release, VirtualBox 7.0 arrives with a... host of new features. Chief among them are Windows 11 support via TPM, EFI Secure Boot support, full encryption for virtual machines, and a few Linux niceties. From a report: The big news is support for Secure Boot and TPM 1.2 and 2.0, which makes it easier to install Windows 11 without registry hacks (the kind Oracle recommended for 6.1 users). It's strange to think about people unable to satisfy Windows 11's security requirements on their physical hardware, but doing so with a couple clicks in VirtualBox, but here we are. VirtualBox 7.0 also allows virtual machines to run with full encryption, not just inside the guest OSâ"but logs, saved states, and other files connected to the VM. At the moment, this support only works through the command line, "for now," Oracle notes in the changelog.

This is the first official VirtualBox release with a Developer Preview for ARM-based Macs. Having loaded it on an M2 MacBook Air, I can report that the VirtualBox client informs you, extensively and consistently, about the non-production nature of your client. The changelog notes that it's an "unsupported work in progress" that is "known to have very modest performance." A "Beta Warning" shows up in the (new and unified) message center, and in the upper-right corner, a "BETA" warning on the window frame is stacked on top of a construction-style "Dev Preview" warning sign. It's still true that ARM-based Macs don't allow for running operating systems written for Intel or AMD-based processors inside virtual machines. You will, however, be able to run ARM-based Linux installations in macOS Venture that can themselves run x86 processors using Rosetta, Apple's own translation layer.

Arm might not think RISC-V is a threat to its newfound foothold in the datacenter, but growing pressure on Chinese chipmaking could ultimately change that, Forrester Research analyst Glenn O'Donnell tells The Register. From the report: Over the past few years the US has piled on export bans and trade restrictions on Chinese chipmakers in an effort to stall the country's semiconductor industry. This has included barring companies with ties to the Chinese military from purchasing x86 processors and AI kit from the likes of Intel, AMD, and Nvidia. "Because the US-China trade war restricts x86 sales to China, Chinese infrastructure vendors and cloud providers need to adapt to remain in business," O'Donnell said. "They initially pivoted to Arm, but trade restrictions exist there too. Chinese players are showing great interest in RISC-V."

RISC-V provides China with a shortcut around the laborious prospect of developing their own architecture. "Coming up with a whole new architecture is nearly impossible," O'Donnell said. But "a design based on some architecture is very different from the architecture itself." So it should come as no surprise that the majority of RISC-V members are based in China, according to a report published last year. And the country's government-backed Chinese Academy of Sciences is actively developing open source RISC-V performance processors.

Alibaba's T-Head, which is already deploying Arm server processors and smartNICs, is also exploring RISC-V-based platforms. But for now, they're largely limited to edge and IoT appliances. However, O'Donnell emphasizes that there is no technical reason that would prevent someone from developing a server-grade RISC-V chip. "Similar to Arm, many people dismiss RISC-V as underpowered for more demanding applications. They are wrong. Both are architectures, not specific designs. As such, one can design a powerful processor based on either architecture," he said. [...] One of the most attractive things about RISC-V over Softbank-owned Arm is the relatively low cost of building chips based on the tech, especially for highly commoditized use cases like embedded processors, O'Donnell explained. While nowhere as glamorous as something like a server CPU, embedded applications are one of RISC-V's first avenues into the datacenter. [...] These embedded applications are where O'Donnell expects RISC-V will see widespread adoption, including in the datacenter. Whether the open source ISA will rise to the level of Arm or x86 is another matter entirely.

An anonymous reader quotes a report from Ars Technica: A stable version of Linux 6.0 is out, with 15,000 non-merge commits and a notable version number for the kernel. And while major Linux releases only happen when the prior number's dot numbers start looking too big -- there is literally no other reason" -- there are a lot of notable things rolled into this release besides a marking in time. Most notable among them could be a patch that prevents a nearly two-decade slowdown for AMD chips, based on workaround code for power management in the early 2000s that hung around for far too long. [...]

Intel's new Arc GPUs are supported in their discrete laptop form in 6.0 (though still experimental). Linux blog Phoronix notes that Intel's ARC GPUs all seem to run on open source upstream drivers, so support should show up for future Intel cards and chipsets as they arrive on the market. Linux 6.0 includes several hardware drivers of note: fourth-generation Intel Xeon server chips, the not-quite-out 13th-generation Raptor Lake and Meteor Lake chips, AMD's RDNA 3 GPUs, Threadripper CPUs, EPYC systems, and audio drivers for a number of newer AMD systems. One small, quirky addition points to larger things happening inside Linux. Lenovo's ThinkPad X13s, based on an ARM-powered Qualcomm Snapdragon chip, get some early support in 6.0. ARM support is something Linux founder Linus Torvalds is eager to see [...].

Among other changes you can find in Linux 6.0, as compiled by LWN.net (in part one and part two):
- ACPI and power management improvements for Sapphire Rapids CPUs
- Support for SMB3 file transfer inside Samba, while SMB1 is further deprecated
- More work on RISC-V, OpenRISC, and LoongArch technologies
- Intel Habana Labs Gaudi2 support, allowing hardware acceleration for machine-learning libraries
- A "guest vCPU stall detector" that can tell a host when a virtual client is frozen Ars' Kevin Purdy notes that in 2022, "there are patches in Linux 6.0 to help Atari's Falcon computers from the early 1990s (or their emulated descendants) better handle VGA modes, color, and other issues."

Not included in this release are Rust improvements, but they "are likely coming in the next point release, 6.1," writes Purdy.

AMD engineer K Prateek Nayak recently uncovered that a 20 year old chipset workaround in the Linux kernel still being applied to modern AMD systems is responsible in some cases for hurting performance on modern Zen hardware. Fortunately, a fix is on the way for limiting that workaround to old systems and in turn helping with performance for modern systems. Phoronix reports: Last week was a patch posted for the ACPI processor idle code to avoid an old chipset workaround on modern AMD Zen systems. Since ACPI support was added to the Linux kernel in 2002, there has been a "dummy wait op" to deal with some chipsets where STPCLK# doesn't get asserted in time. The dummy I/O read delays further instruction processing until the CPU is fully stopped. This was a problem with at least some AMD Athlon era systems with a VIA chipset... But not a problem with newer chipsets of roughly the past two decades.

With this workaround still being applied to even modern AMD systems, K Prateek Nayak discovered: "Sampling certain workloads with IBS on AMD Zen3 system shows that a significant amount of time is spent in the dummy op, which incorrectly gets accounted as C-State residency. A large C-State residency value can prime the cpuidle governor to recommend a deeper C-State during the subsequent idle instances, starting a vicious cycle, leading to performance degradation on workloads that rapidly switch between busy and idle phases. One such workload is tbench where a massive performance degradation can be observed during certain runs."

At least for Tbench, this long-time, unconditional workaround in the Linux kernel has been hurting AMD Ryzen / Threadripper / EPYC performance in select workloads. This workaround hasn't affected modern Intel systems since those newer Intel platforms use the alternative MWAIT-based intel_idle driver code path instead. The AMD patch evolved into this patch by Intel Linux engineer Dave Hansen. That patch to limit the "dummy wait" workaround to old systems is already queued into TIP's x86/urgent branch. With it going the route of "x86/urgent" and for fixing a overzealous workaround that isn't needed on modern hardware, it's likely this patch will be submitted this week still for the Linux 6.0 kernel rather than needing to wait until the next (v6.1) merge window.

AMD unveiled its 5nm Ryzen 7000 lineup today, outlining the details of four new models that span from the 16-core $699 Ryzen 9 7950X flagship, which AMD claims is the fastest CPU in the world, to the six-core $299 Ryzen 5 7600X, the lowest bar of entry to the first family of Zen 4 processors. Tom's Hardware reports: Ryzen 7000 marks the first 5nm x86 chips for desktop PCs, but AMD's newest chips don't come with higher core counts than the previous-gen models. However, frequencies stretch up to 5.7 GHz - an impressive 800 MHz improvement over the prior generation -- paired with an up to 13% improvement in IPC from the new Zen 4 microarchitecture. That results in a 29% improvement in single-threaded performance over the prior-gen chips. That higher performance also extends out to threaded workloads, with AMD claiming up to 45% more performance in some threaded workloads. AMD says these new chips power huge generational gains over the prior-gen Ryzen 5000 models, with 29% faster gaming and 44% more performance in productivity apps. Going head-to-head with Intel's chips, AMD claims the high-end 7950X is 11% faster overall in gaming than Intel's fastest chip, the 12900K, and that even the low-end Ryzen 5 7600X beats the 12900K by 5% in gaming. It's noteworthy that those claims come with a few caveats [...].

The Ryzen 7000 processors come to market on September 27, and they'll be joined by new DDR5 memory products that support new EXPO overclocking profiles. AMD's partners will also offer a robust lineup of motherboards - the chips will snap into new Socket AM5 motherboards that AMD says it will support until 2025+. These motherboards support DDR5 memory and the PCIe 5.0 interface, bringing the Ryzen family up to the latest connectivity standards. The X670 Extreme and standard X670 chipsets arrive first in September, while the more value-oriented B650 options will come to market in October. That includes the newly announced B650E chipset that brings full PCIe 5.0 connectivity to budget motherboards, while the B650 chipset slots in as a lower-tier option. The Ryzen 7000 lineup also brings integrated RDNA 2 graphics to all of the processors in the stack, a first for the Ryzen family.

An anonymous reader shares a report: While mostly of benefit to server administrators with large fleets of hardware, Linux 6.1 aims to make it easier to help spot problematic CPUs/cores by reporting the likely socket and core when a segmentation fault occurs, which can help in spotting any trends if routinely finding the same CPU/core is causing problems. Queued up now in TIP's x86/cpu branch for the Linux 6.1 merge window in October is a patch to print the likely CPU at segmentation fault time. Printing the likely CPU core and socket when a seg fault occurs can be beneficial if routinely finding seg faults happening on the same CPU package or particular core.

An anonymous reader quotes a report from Ars Technica: Skirting the official macOS system requirements to run new versions of the software on old, unsupported Macs has a rich history. Tools like XPostFacto and LeopardAssist could help old PowerPC Macs run newer versions of Mac OS X, a tradition kept alive in the modern era by dosdude1's patchers for Sierra, High Sierra, Mojave, and Catalina. For Big Sur and Monterey, the OpenCore Legacy Patcher (OCLP for short) is the best way to get new macOS versions running on old Macs. It's an offshoot of the OpenCore Hackintosh bootloader, and it's updated fairly frequently with new features and fixes and compatibility for newer macOS versions. The OCLP developers have admitted that macOS Ventura support will be tough, but they've made progress in some crucial areas that should keep some older Macs kicking for a little bit longer.

[...] First, while macOS doesn't technically include system files for pre-AVX2 Intel CPUs, Apple's Rosetta 2 software does still include those files, since Rosetta 2 emulates the capabilities of a pre-AVX2 x86 CPU. By extracting and installing those files in Ventura, you can re-enable support on Ivy Bridge and older CPUs without AVX2 instructions. And this week, Grymalyuk showed off another breakthrough: working graphics support on old Metal-capable Macs, including machines as old as the 2014 5K iMac, the 2012 Mac mini, and even the 2008 cheese grater-style Mac Pro tower. The OCLP team still has other challenges to surmount, not least of which will involve automating all of these hacks so that users without a deep technical understanding of macOS's underpinnings can continue to set up and use the bootloader. Grymalyuk still won't speculate about a timeframe for official Ventura support in OCLP. But given the progress that has been made so far, it seems likely that people with 2012-and-newer Macs should still be able to run Ventura on their Macs without giving up graphics acceleration or other important features.

Version 9.3 of NetBSD is here, able to run on very low-end systems and with that authentic early-1990s experience. The Register reports: Version 9.3 comes some 15 months after NetBSD 9.2 and boasts new and updated drivers, improved hardware support, including for some recent AMD and Intel processors, and better handling of suspend and resume. The next sentence in the release announcement, though, might give some readers pause: "Support for wsfb-based X11 servers on the Commodore Amiga." This is your clue that we are in a rather different territory from run-of-the-mill PC operating systems here. A notable improvement in NetBSD 9.3 is being able to run a graphical desktop on an Amiga. This is a 2022 operating system that can run on late-1980s hardware, and there are not many of those around.

NetBSD supports eight "tier I" architectures: 32-bit and 64-bit x86 and Arm, plus MIPS, PowerPC, Sun UltraSPARC, and the Xen hypervisor. Alongside those, there are no less than 49 "tier II" supported architectures, which are not as complete and not everything works -- although almost all of them are on version 9.3 except for the version for original Acorn computers with 32-bit Arm CPUs, which is still only on NetBSD 8.1. There's also a "tier III" for ports which are on "life support" so there may be a risk Archimedes support could drop to that. This is an OS that can run on 680x0 hardware, DEC VAX minicomputers and workstations, and Sun 2, 3, and 32-bit SPARC boxes. In other words, it reaches back as far as some 1970s hardware. Let this govern your expectations. For instance, in VirtualBox, if you tell it you want to create a NetBSD guest, it disables SMP support.

Microsoft software engineer Stephen Hemminger has proposed removing the DECnet protocol handling code from the Linux kernel. The Register reports: The timing is ironic, as this comes just two weeks after VMS Software Inc announced that OpenVMS 9.2 was really ready this time... That announcement, of course, came some months after the first time it announced [PDF] version 9.2 [...]. The last maintainer of the DECnet code was Red Hat's Christine Caulfield, who flagged the code as orphaned in 2010. The change is unlikely to vastly inconvenience many people: VMS is the last even slightly mainstream OS that used DECnet, and VMS has supported TCP/IP for a long time. Indeed, for decades, the oldest email in this reporter's "sent" folder was a 1993 enquiry about the freeware CMUIP stack for VMS.

One of the easier ways to bootstrap VMS on an elderly VAX these days is to install it on the SimH VAX hardware simulator, and then net-boot the real VAX from the simulated one. Anyone keen enough to do that will be competent to run an older version of Linux just for the purpose. Although their existence is rapidly being forgotten today, TCP/IP is not the only network protocol around, and as late as the mid-1990s it wasn't even the dominant one. The Linux kernel used to support multiple network protocols, but they are disappearing fast. [...] For a long time, DECnet was a significant network protocol. DEC supplied a client stack called PathWorks to let DOS, Windows and Mac clients connect to VAX servers, not only for file and print, but also terminal connections and X.11. Whole worldwide WANs ran over DECnet, and as a teenage student, your correspondent enjoyed exploring them.

The New York Times' product-recommendation service "Wirecutter" has sparked widening criticism about how laptops are reviewed. The technology/Apple blog Daring Fireball first complained that they "institutionally fetishize price over quality". That makes it all the more baffling that their recommended "Best Laptop" — not best Windows laptop, but best laptop, full stop — is a Dell XPS 13 that costs $1,340 but is slower and gets worse battery life (and has a lower-resolution display) than their "best Mac laptop", the $1,000 M1 MacBook Air.
Technically Dell's product won in a category titled "For most people: The best ultrabook" (and Wikipedia points out that ultrabook is, after all, "a marketing term, originated and trademarked by Intel.") But this leads blogger Jack Wellborn to an even larger question: why exactly do reviewers refuse to do a comparison between Wintel laptops and Apple's MacBooks? Is it that reviewers don't think they could fairly compare x86 and ARM laptops? It seems easy enough to me. Are they afraid that constantly showing MacBooks outperforming Wintel laptops will give the impression that they are in the bag for Apple? I don't see why. Facts are facts, and a lot of people need or want to buy a Windows laptop regardless. I can't help but wonder if, in the minds of many reviewers, MacBooks were PCs so long as they used Intel, and therefore they stopped being PCs once Apple switched to using their own silicon.
Saturday Daring Fireball responded with their own assessment. "Reviewers at ostensibly neutral publications are afraid that reiterating the plain truth about x86 vs. Apple silicon — that Apple silicon wins handily in both performance and efficiency — is not going to be popular with a large segment of their audience. Apple silicon is a profoundly inconvenient truth for many computer enthusiasts who do not like Macs, so they've gone into denial..."

Both bloggers cite as an example this review of Microsoft's Surface Laptop Go 2, which does begin by criticizing the device's old processor, its un-backlit keyboard, its small selection of ports, and its low-resolution touchscreen. But it ultimately concludes "Microsoft gets most of the important things right here, and there's no laptop in this price range that doesn't come with some kind of trade-off...." A crime of omission — or is the key phrase "in this price range"? (Which gets back to Daring Fireball's original complaint about "fetishizing price over quality.") Are Apple's new Silicon-powered laptops sometimes being left out of comparisons because they're more expensive?

In an update, Wellborn acknowledges that this alleged refusal-to-compare apparently actually precedes Apple's launch of its M1 chip. But he argues that now it's more important than ever to begin making those comparisons: It's a choice between a hot and noisy and/or slow PC laptop running Windows and a cool, silent, and fast MacBook. Most buyers don't know that choice now exists, and it's the reviewer's job to educate them. Excluding MacBooks from consideration does those buyers a considerable disservice.

"T2 SDE is not just a regular Linux distribution," reads the announcement. "It is a flexible Open Source System Development Environment or Distribution Build Kit (others might even name it Meta Distribution). T2 allows the creation of custom distributions with state of the art technology, up-to-date packages and integrated support for cross compilation."

Slashdot reader ReneR writes: The T2 project released a major milestone update, shipping full support for 25 CPU architectures, variants, and C libraries. Support for cross compiling was further improved to also cover Rust, Ada, ObjC, Fortran, and Go!

This is also the first major release where an AI powered package update bot named 'data' contributed more changes than human contributors combined! [Data: 164, humans: 141]

T2 is known for its sophisticated cross compile support as well as supporting nearly all existing CPU architectures: alpha, arc, arm, arm64, avr32, hppa, ia64, m68k, mipsel, mips64, nios2, ppc, ppc64-32, ppc64le, riscv, riscv64, s390x, spare, sparc64, superh x86, x86-64 and x32 for a wide use in Embedded systems. The project also still supports the Sony PS3, Sgi Octane and Sun workstations as well as state of the art ARM64, RISCV64 as well as AMD64 for regular cloud, server, or simply enthusiast workstation use.

A senior systems administrator at the Free Software Foundation points out that they're running free software in two data centers and over a hundred virtual machine — each and every one with "a freedom-respecting BIOS."

But the "how" is surprisingly intricate: [E]arlier this week, we replaced "Columbia", the last of any FSF-run machines running a nonfree BIOS....

At FSF, our current standard is ASUS KGPE-D16 motherboards with AMD CPUs 6200 series CPUs released in 2012. For the BIOS, we install Libreboot, the easy-to-install, 100% free software replacement for proprietary BIOS/boot programs, or a version of Coreboot that is carefully built to avoid including any nonfree blobs. They are fast enough for our needs, and we expect this to be the case for many more years to come. They are also very affordable systems. We are also working toward supporting Raptor Computer Systems' newer and more powerful Talos II, as well as Blackbird motherboards that use IBM POWER9 CPUs. The POWER9 CPU architecture is called "PowerPC 64-bit little endian," abbreviated "ppc64el...." The Raptor motherboards come with entirely free firmware — and even have free hardware designs!

However, this type of migration has its challenges. For example, the first thing we needed to address before using these motherboards is that the main operating system we use, Trisquel GNU/Linux, didn't previously run on pp64el. So, earlier this year, we set up a Raptor POWER9 computer running Debian (without using any nonfree parts of Debian repositories) and loaned it to the maintainers of Trisquel for as long as needed. And now, we are proud to say that the upcoming Trisquel 11 release will support POWER9...!

Before I decommissioned Columbia, I ran a dmidecode, which told me that the BIOS program fit within a single megabyte of space. Often, very simplistic firmware becomes more complicated in later models, and that also usually means it has a growing significance for a user's software freedom. Some newer nonfree BIOSes have grown into operating systems in their own right, sometimes with large programs such as a full Web browser.

There is no fully-free BIOS available for x86 Intel and AMD CPUs released after about 2013. The key blocking factor is that those CPUs require certain firmware in the BIOS, like Intel Management Engine. Those CPUs will also refuse to run firmware that hasn't been cryptographically signed by private keys controlled by AMD and Intel, and AMD and Intel will only sign their own nonfree firmware. At the FSF, we refuse to run that nonfree firmware, and we applaud the many people who also avoid it. For those people who do run those Intel or AMD systems, running Coreboot or Osboot is still a step up the Freedom Ladder for the software freedom of your BIOS.

The road to freedom is a long road. We hope our dedication to achieve milestones like these can inspire the free software movement.

Wall Street analysts estimate TSMC will grow second-quarter revenue 43 percent quarter-over-quarter to $18.1 billion. Intel, on the other hand, is expected to see sales decline 2 percent sequentially to $17.98 billion in the same period, according to estimates collected by Yahoo Finance. The Register reports: The potential for TSMC to surpass Intel in quarterly revenue is indicative of how demand has grown for contract chip manufacturing, fueled by companies like Qualcomm, Nvidia, AMD, and Apple who design their own chips and outsource manufacturing to foundries like TSMC. This trend has created a quandary for Intel. The semiconductor giant has traditionally manufactured the chips it designs as part of its integrated device manufacturing model but the company is now increasingly reliant on TSMC and other foundries for certain components, while expanding its own manufacturing capacity in the West.

The kicker is that Intel plans to use this increased capacity to produce more of its own chips while also supporting its revitalized foundry business, which hopes to take business from TSMC and South Korea's Samsung, the industry's other leading-edge chipmaker, in the future. This new strategy by Intel is called IDM 2.0, and it means the chipmaker will have to juggle two somewhat conflicting objectives:

- taking foundry market share away from TSMC and Samsung by convincing various fabless chip designers to use its plants;
- and using leading-edge nodes from TSMC and Samsung for certain components to compete with fabless companies like AMD and Nvidia. "Samsung has already surpassed Intel as the largest semiconductor company by revenue, so TSMC potentially growing larger than the x86 giant further underscores the tentative position Intel is in," concludes the report.

An anonymous reader quotes a report from Ars Technica: One of the few things that Intel Macs can do that Apple Silicon Macs can't is run operating systems written for Intel or AMD processors inside of virtual machines. Most notably, this has meant that there is currently no legal way to run Windows on an Apple Silicon Mac. Apple Silicon Macs can, however, run operating systems written for Arm processors inside of virtual machines, including other versions of macOS and Arm-compatible versions of Linux. And those Linux VMs are getting a new feature in macOS Ventura: the ability to run apps written for x86 processors using Rosetta, the same binary translation technology that allows Apple Silicon Macs to run apps written for Intel Macs.

Apple's documentation will walk you through the requirements for using Rosetta within a Linux guest operating system -- it requires creating a shared directory that both macOS and Linux can access and running some terminal commands in Linux to get it set up. But once you do those steps, you'll be able to enjoy the wider app compatibility that comes with being able to run x86 code as well as Arm code. Some developers, including Hector Martin of the Asahi Linux project and Twitter user @never_released, have already found that these steps can also enable Rosetta on non-Apple ARM CPUs as long as they're modern enough to support at least version 8.2 of the Arm instruction set. As Martin points out, this isn't strictly legal because of macOS's licensing restrictions, and there are some relatively minor Apple-specific hardware features needed to unlock Rosetta's full capabilities.

Mike Bouma writes: Version 1.7 of AROS One for x86 has just been released and it's a distro of the "AROS Research Operating System," originally "Amiga Research Operating System." It's a standalone, free and open-source multi-media centric operating system that's designed to be portable, flexible, efficient and lightweight and can be seen dual booting with Windows 10 on an Acer laptop here. The most popular AROS specific community portal is AROS Exec.

Parts of AROS were used to create the commercial PowerPC based Amiga-like operating system MorphOS, which has recently seen a new release as well, version 3.17. The most popular MorphOS specific community portal is MorphZone.

Lotus-1-2-3, an ancient spreadsheet program from Lotus Software (and later IBM), has been ported to a new operating system. drewsup writes: As reported by The Register, a Lotus 1-2-3 enthusiast called Tavis Ormandy (who is also a bug-hunter for Google Project Zero), managed to successfully port the program onto Linux, which seems to be quite the feat of reverse engineering. It's important to stress that this isn't an emulated program, but rather the original 1990 Lotus 1-2 -- for x86 Unix running natively on modern x86 Linux.

AMD announced the Ryzen 5000 C-series for Chromebooks today. "The top chip in the series has eight of AMD's Zen 3 cores, giving systems that use it more x86 CPU cores than any other Chromebook," reports Ars Technica. From the report: The 7nm Ryzen 5000 C-series ranges from the Ryzen 3 5125C with two Zen 3 cores and a base and boost clock speed of 3 GHz, up to the Ryzen 7 5825C with eight cores and a base clock speed of 2 GHz that can boost to 4.5 GHz. For comparison, Intel's Core i7-1185G7, found in some higher end Chromebooks, has four cores and a base clock speed of 3 GHz that can boost to 4.8 GHz.

On their own, the chips aren't that exciting. They seemingly offer similar performance to the already-released Ryzen 5000 U-series chips. The Ryzen 5000 C-series also uses years-old Vega integrated graphics rather than the upgraded RDNA 2 found in Ryzen 6000 mobile chips, which, upon release, AMD said are "up to 2.1 times faster." But for someone who's constantly pushing their Chromebook to do more than just open a Chrome tab or two, the chips bring potentially elevated performance than what's currently available.

An anonymous reader quotes a report from Ars Technica: Qualcomm bought a chipmaking startup called Nuvia back in March of 2021, and later that year, the company said it would be using Nuvia's talent and technology to create high-performance custom-designed ARM chips to compete with Apple's processor designs. But if you're waiting for a truly high-performance Windows PC with anything other than an Intel or AMD chip in it, you'll still be waiting for a bit. Qualcomm CEO Christian Amon mentioned during the company's most recent earnings call that its high-performance chips were on track to land in consumer devices "in late 2023."

Qualcomm still plans to sample chips to its partners later in 2022, a timeframe it has mentioned previously and has managed to stick to. A gap between sampling and mass production is typical, giving Qualcomm time to work out bugs and improve chip yields and PC manufacturers more time to design and build finished products that incorporate the chips. [...] Like Apple's processors, Nuvia's support the ARM instruction set but don't use off-the-shelf ARM Cortex CPU designs. These processor cores have been phenomenally successful in commodity SoCs that power everything from Android phones to smart TVs, and they helped popularize the practice of combining large, high-performance CPU cores and small, high-efficiency CPU cores together in the same design. But they rarely manage to top the performance charts, something that's especially noticeable when they're running x86 code on Windows with a performance penalty.

"Everyone's favorite security focused operating system, OpenBSD 7.1 has been released for a number of architectures," writes long-time Slashdot reader ArchieBunker, "including Apple M1 chips."

Phoronix calls it "the newest version of this popular, security-minded BSD operating system." With OpenBSD 7.1, the Apple Silicon support is now considered "ready for general use" with keypad/touchpad support for M1 laptops, a power management controller driver added, I2C and SPI controller drivers, and a variety of other driver additions for supporting the Apple Silicon hardware.

OpenBSD 7.1 also has a number of other improvements benefiting the 64-bit ARM (ARM64) and RISC-V architectures. OpenBSD 7.1 also brings SMP kernel improvements, support for futexes with shared anonymous memory, and more. On the graphics front there is updating the Linux DRM code against the state found in Linux 5.15.26 as well as now enabling Intel Elkhart Lake / Jasper Lake / Rocket Lake support.
The Register notes OpenBSD now "supports a surprisingly wide range of hardware: x86-32, x86-64, ARM7, Arm64, DEC Alpha, HP PA-RISC, Hitachi SH4, Motorola 88000, MIPS64, SPARC64, RISC-V 64, and both Apple PowerPC and IBM POWER." The Register's FOSS desk ran up a copy in VirtualBox, and we were honestly surprised how quick and easy it was. By saying "yes" to everything, it automatically partitioned the VM's disk into a rather complex array of nine slices, installed the OS, a boot loader, an X server and display manager, plus the FVWM window manager. After a reboot, we got a graphical login screen and then a rather late-1980s Motif-style desktop with an xterm.

It was easy to install XFCE, which let us set the screen resolution and other modern niceties, and there are also KDE, GNOME, and other pretty front-ends, plus plenty of familiar tools such as Mozilla apps, LibreOffice and so on....

We were expecting to have to do a lot more work. Yes, OpenBSD is a niche OS, but the project gave the world OpenSSH, LibreSSL, the PF firewall as used in macOS, much of Android's Bionic C library, and more besides.... In a world of multi-gigabyte OSes, it's quite refreshing. It felt like stepping back into the early 1990s, the era of Real Unix, when you had to put in some real effort and learn stuff in order to bend the OS to your will — but in return, you got something relatively bulletproof.

Russia is adapting to a world where it no longer has access to many technologies abroad with the development of a new supercomputer platform that can use foreign x86 processors such as Intel's in combination with the country's homegrown Elbrus processors. The Register reports: The new supercomputer reference system, dubbed "RSK Tornado," was developed on behalf of the Russian government by HPC system integrator RSC Group, according to an English translation of a Russian-language press release published March 30. RSC said it created RSK Tornado as a "unified interoperable" platform to "accelerate the pace of important substitution" for HPC systems, data processing centers and data storage systems in Russia. In other words, the HPC system architecture is meant to help Russia quickly adjust to the fact that major chip companies such as Intel, AMD and TSMC -- plus several other technology vendors, like Dell and Lenovo -- have suspended product shipments to the country as a result of sanctions by the US and other countries in reaction to Russia's invasion of Ukraine.

RSK Tornado supports up to 104 servers in a rack, with the idea being to support foreign x86 processors (should they come available) as well as Russia's Elbrus processors, which debuted in 2015. The hope appears to be the ability for Russian developers to port HPC, AI and big data applications from x86 architectures to the Elbrus architecture, which, in theory, will make it easier for Russia to rely on its own supply chain and better cope with continued sanctions from abroad. RSK Tornado systems software is RSC proprietary and is currently used to orchestrate supercomputer resources at the Interdepartmental Supercomputer Center of the Russian Academy of Sciences, St Petersburg Polytechnic University and the Joint Institute for Nuclear Research. RSC claims to have also developed its own liquid-cooling system for supercomputers and data storage systems, the latter of which can use Elbrus CPUs too.
