Linux creator Linus Torvalds has released version 6.11 of the open-source operating system kernel. The new release, while not considered major by Torvalds, introduces several notable improvements for AMD hardware users and Arch Linux developers. ZDNet: This latest version introduces several enhancements, particularly for AMD hardware users, while offering broader system improvements and new capabilities. These include:
RDNA4 Graphics Support: The kernel now includes baseline support for AMD's upcoming RDNA4 graphics architecture. This early integration bodes well for future AMD GPU releases, ensuring Linux users have day-one support.
Core Performance Boost: The AMD P-State driver now includes handling for AMD Core Performance Boost. This driver gives AMD Core users more granular control over turbo and boost frequency ranges.
Fast Collaborative Processor Performance Control (CPPC) Support: Overclockers who want the most power possible from their computers will be happy with this improvement to the AMD P-State driver. This feature enhances power efficiency on recent Ryzen (Zen 4) mobile processors. This can improve performance by 2-6% without increasing power consumption.
AES-GCM Crypto Performance: AMD and Intel CPUs benefit from significantly faster AES-GCM encryption and decryption processing, up to 160% faster than previous versions.

Intel lost a bid to design and manufacture Sony's PlayStation 6 chip in 2022, dealing a blow to its contract manufacturing business. The contract, worth potentially billions in revenue, went to rival AMD after Intel failed to agree on pricing with Sony, Reuters reported Monday.

Discussions between the companies spanned months and involved top executives. Intel's loss has hampered CEO Pat Gelsinger's turnaround strategy, which hinges on expanding the company's foundry operations. The PlayStation deal would have provided steady business for Intel's struggling manufacturing arm, which reported $7 billion in operating losses last quarter. Sony's need for backwards compatibility with older PlayStation models complicated Intel's bid, as AMD designed chips for previous console generations, the report adds.

Last October Slashdot reported on René Rebe's discovery of a random illegal instruction speculation bug on AMD Ryzen 7000-series and Epyc Zen 4 CPUs — which Rebe discussed on his YouTube channel.

But this week's YouTube episode had a different ending, reports Tom's Hardware... Two days ago, tech streamer and host of Code Therapy René Rebe was streaming one of many T2 Linux (his own custom distribution) development sessions from his office in Germany when he abruptly had to remove his microphone and walk off camera due to the arrival of police officers. The officers subsequently cuffed him and took him to the station for an hour of questioning, a span of time during which the stream continued to run until he made it back...

[T]he police seemingly have no idea who did it and acted based on a tip sent with an email. Finding the perpetrators could take a while, and options will be fairly limited if they don't also live in Germany.
Rebe has been contributing to Linux "since as early as 1998," according to the article, "and started his own T2 SD3 Embedded Linux distribution in 2004, as well." (And he's also a contributor to many other major open source projects.)

The article points out that Linux and other communities "are compelled by little-to-no profit motive, so in essence, René has been providing unpaid software development for the greater good for the past two decades."

In 2015 Amazon purchased chip designer Annapurna Labs, remembers IEEE Spectrum, "and proceeded to design CPUs, AI accelerators, servers, and data centers as a vertically-integrated operation."

The article argues that while AMD, Nvidia, and other big-name processor companies may also want to control the full stack (purchasing server, software, and interconnect companies) — Amazon Web Services "got there ahead of most of the competition." (IEEE Spectrum interviews Ali Saidi, technical lead for the AWS Graviton series of CPUs, and Rami Sinno, director of engineering at Annapurna Labs, on "the advantage of vertically-integrated design — and Amazon-scale...") Sinno: I was working at Arm, and I was looking for the next adventure, looking at where the industry is heading and what I want my legacy to be. I looked at two things: One is vertically integrated companies, because this is where most of the innovation is — the interesting stuff is happening when you control the full hardware and software stack and deliver directly to customers.

And the second thing is, I realized that machine learning, AI in general, is going to be very, very big. I didn't know exactly which direction it was going to take, but I knew that there is something that is going to be generational, and I wanted to be part of that. I already had that experience prior when I was part of the group that was building the chips that go into the Blackberries; that was a fundamental shift in the industry. That feeling was incredible, to be part of something so big, so fundamental. And I thought, "Okay, I have another chance to be part of something fundamental."

[...] At the end of the day, our responsibility is to deliver complete servers in the data center directly for our customers. And if you think from that perspective, you'll be able to optimize and innovate across the full stack. It might not be at the transistor level or at the substrate level or at the board level. It could be something completely different. It could be purely software. And having that knowledge, having that visibility, will allow the engineers to be significantly more productive and delivery to the customer significantly faster. We're not going to bang our head against the wall to optimize the transistor where three lines of code downstream will solve these problems, right...?

We've had very good luck with recent college grads. Recent college grads, especially the past couple of years, have been absolutely phenomenal. I'm very, very pleased with the way that the education system is graduating the engineers and the computer scientists that are interested in the type of jobs that we have for them.
It's an interesting glimpse into the unique world of designing chips at Amazon.

Graviton technical lead Saidi: I've been here about seven and a half years. When I joined AWS, I joined a secret project at the time. I was told: "We're going to build some Arm servers. Tell no one...

"In chip design, there are many different competing optimization points. You have all of these conflicting requirements, you have cost, you have scheduling, you've got power consumption, you've got size, what DRAM technologies are available and when you're going to intersect them... It ends up being this fun, multifaceted optimization problem to figure out what's the best thing that you can build in a timeframe. And you need to get it right."

An anonymous Slashdot reader writes: Haiku (the MIT-licensed operating system, inspired by BeOS) has released its fifth beta for Haiku R1.

Some new features include improved UI color management, improved dark mode coloring, Tracker improvements, TUN/TAP support for VPN connections, TCP throughput improvements, performance optimizations, UFS2 (BSD's filesystem) read-only support, new FAT filesystem driver, improved hardware support, improved POSIX compliance, improved performance, and more.
Slashdot has been covering the fate of the BeOS since 2000 (as well as the short-lived derivative project ZETA — and Haiku).

And now "With a history of over two decades and previously known as OpenBeOS, today's Haiku is pushing forward..." writes the site NotebookCheck: Haiku is a spiritual successor to BeOS, with a focus on a clean and user-friendly design paired with low system requirements. The minimum system requirements are still an Intel Pentium II/AMD Athlon CPU or better, at least 384 MB RAM, an 800x600 screen, and at least 3GB storage. It works on both 32-bit and 64-bit x86 PCs, and the 32-bit version can run many unmodified BeOS applications. It might be the best desktop open-source operating system not based on Linux or Unix... It works well in a virtual machine like VirtualBox or UTM.

AMD has introduced Variable Graphics Memory (VGM) for its AI 300 "Strix Point" laptops, allowing users to convert up to 75% of their system memory into dedicated VRAM via the AMD Adrenalin app, enhancing gaming performance for titles requiring more VRAM. The Verge reports: You might be wondering: does that extra video memory actually make a difference? Well, it depends on the game. Some games, like Alan Wake II, require as many as 6GB of VRAM and will throw errors at launch if you're short -- Steam Deck, Asus ROG Ally, and Lenovo Legion Go buyers have been tweaking their VRAM settings for some time to take games to the threshold of playability. But in early testing with the Asus Zenbook S 16, a Strix Point laptop that's already shipped with this feature, my colleague Joanna Nelius saw that turning it on isn't a silver bullet for every game. With 8GB of VRAM, the laptop played Control notably faster (65fps vs. 54fps), but some titles had smaller boosts, no boost, or even slight frame rate decreases.

Intel launched its new Core Ultra 200V-series processors on Tuesday, promising significant improvements in power efficiency, performance, and battery life over competitors and previous generations. The company claims the chips offer "historic x86 power efficiency" and the "world's fastest mobile CPU cores." The processors, available for pre-order in OEM systems and shipping September 24, feature four Lion Cove P-cores and four Skymont E-cores with boost speeds up to 5.1 GHz.

Intel says the chips deliver up to 20.1 hours of battery life, Tom's Hardware reports, outperforming Qualcomm's Snapdragon X Elite by nearly two hours and AMD's chips by almost four hours. Intel asserts a 30% faster gaming performance than competing processors and highlighted compatibility issues with Qualcomm's chips, noting that nearly two dozen games used for benchmarking failed to run on X Elite chips. The company claims up to 64% advantage in single-threaded performance over Qualcomm Snapdragon X Elite and up to 33% over AMD Strix Point HX370.

Nvidia dominates the chips at the center of the AI boom. It wants to conquer almost everything else that makes those chips tick, too. From a report: Chief Executive Jensen Huang is increasingly broadening his company's focus -- and seeking to widen its advantage over competitors -- by offering software, data-center design services and networking technology in addition to its powerful silicon brains. More than a supplier of a valuable hardware component, he is trying to build Nvidia into a one-stop shop for all the key elements in the data centers where tools like OpenAI's ChatGPT are created and deployed -- or what he calls "AI factories."

Huang emphasized Nvidia's growing prowess at data-center design following an earnings report Wednesday that exceeded Wall Street forecasts. The report came days after rival AMD agreed to pay nearly $5 billion to buy data-center design and manufacturing company ZT Systems to try to gain ground on Nvidia. "We have the ability fairly uniquely to integrate to design an AI factory because we have all the parts," Huang said in a call with analysts. "It's not possible to come up with a new AI factory every year unless you have all the parts." It is a strategy designed to extend the business success that has made Nvidia one of the world's most valuable companies -- and to insulate it from rivals eager to eat into its AI-chip market share, estimated at more than 80%. Gobbling up more of the value in AI data centers both adds revenue and makes its offerings stickier for customers.

[...] Nvidia is building on the effectiveness of its 17-year-old proprietary software, called CUDA, which enables programmers to use its chips. More recently, Huang has been pushing resources into a superfast networking protocol called InfiniBand, after acquiring the technology's main equipment maker, Mellanox Technologies, five years ago for nearly $7 billion. Analysts estimate that InfiniBand is used in most AI-training deployments. Nvidia is also building a business that supplies AI-optimized Ethernet, a form of networking widely used in traditional data centers. The Ethernet business is expected to generate billions of dollars in revenue within a year, Chief Financial Officer Colette Kress said Wednesday. More broadly, Nvidia sells products including central processors and networking chips for a range of other data-center equipment that is fine-tuned to work seamlessly together.

An anonymous reader quotes a report from overkill.wtf: The team behind popular emulation tool EmuDeck is today announcing something rather special: they've spent the first half of 2024 working on their very first hardware product, called the EmuDeck Machine, and it's due to arrive before the year is out. This EmuDeck Machine is an upcoming, crowdfunded, retro emulation mini PC running Bazzite, a Linux-based system similar to SteamOS. [...] This new EmuDeck Machine comes in two variants, the EM1 running an Intel N97 APU, and the EM2 -- based on an AMD Ryzen 8600G. While both machines are meant as emulation-first devices, the AMD-based variant can easily function as a console-like PC. This is also thanks to some custom work done by the team: "We've optimized the system for maximum power. The default configuration of an 8600G gets you 32 FPS in Cyberpunk; we've managed to reach 47 FPS with a completely stable system, or 60FPS if you use FSR."

Both machines will ship with a Gamesir Nova Lite controller and EmuDeck preinstalled naturally. The team has also preinstalled all available Decky plugins. But that's not all: if the campaign is successful, the EmuDeck team will also work on a docking station for the EM2 that will upgrade the graphics to an AMD Radeon 7600 desktop GPU. With this, in games like Cyberpunk 2077, you'll be able to reach 160 FPS in 1080p as per EmuDeck's measurements. You can preorder the EmuDeck Machines via Indigogo, starting at $322 and shipping in December.

Phoronix's Michael Larabel benchmarked AMD's latest Ryzen 9 9950X in several different Linux distros and found that the Zen 5 chip performs up to 16% faster with the Intel-optimized Clear Linux distro. Here's an excerpt from the report: The Linux distributions for this round of testing on the AMD Ryzen 9 9950X included Arch Linux, CachyOS, Clear Linux, Fedora Workstation 40, Ubuntu 24.04 LTS, and a recent daily snapshot of Ubuntu 24.10 in its current development form. Intel's Clear Linux is the one most interesting for looking at on the new AMD Zen 5 hardware. While there hasn't been so much Clear Linux news in recent times, it remains the most well optimized x86_64 Linux distribution out of the box. Clear Linux makes use of compiler function multi versioning, performance-minded defaults, aggressive compiler CFLAGS/CXXFLAGS defaults, optional AVX-512 usage for more libraries, and many other patches and optimizations in the name of delivering the greatest x86_64 Linux performance. And while not Intel's focus, it works typically on AMD hardware too. [...]

Using the same Ryzen 9 9950X system, all of these Linux distributions were tested in their default / out-of-the-box state. [...] When taking the geometric mean of 59 benchmarks run across all of the Linux distributions on this AMD Ryzen 9 9950X system, Intel's Clear Linux easily took the crown. Ubuntu 24.04 LTS -- which was used for all of the Ryzen 9000 series Linux testing so far on Phoronix -- was the slowest. Tapping Intel's Clear Linux netted a 16% improvement on top of the performance offered by Ubuntu 24.04 LTS! Ubuntu 24.04 with the Ryzen 9000 series was already looking great generationally, but as shown today the performance can be even better with further software optimizations.

The Arch Linux powered CachyOS that is tuned out-of-the-box with a similar aim to Clear Linux also performed great. CachyOS was 7% faster than Ubuntu 24.04 LTS based on the geo mean and 3% faster than upstream Arch Linux itself. For different workloads though the CachyOS advantage over Arch Linux varied from a minimal difference to quite significant advantages. From the performance of PHP and Python scripts atop Clear Linux to compiling various server and HPC minded software, Intel's Clear Linux -- and a commendable second place for CachyOS -- were showing that even greater performance can be achieved on the AMD Ryzen 9 9950X. Even for devoted Ubuntu Linux users, these results did show some nice advantages of the upcoming Ubuntu 24.10 release over Ubuntu 24.04 LTS thanks to the GCC 14 compiler. Ubuntu 24.10 performance is also still subject to change since the current daily ISOs haven't yet moved past the Linux 6.8 kernel while Ubuntu 24.10 in October will be shipping with Linux 6.11.

An anonymous reader quotes a report from Ars Technica, written by Andrew Cunningham: Back in 2013, Nvidia introduced a new technology called G-Sync to eliminate screen tearing and stuttering effects and reduce input lag when playing PC games. The company accomplished this by tying your display's refresh rate to the actual frame rate of the game you were playing, and similar variable refresh-rate (VRR) technology has become a mainstay even in budget monitors and TVs today. The issue for Nvidia is that G-Sync isn't what has been driving most of that adoption. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens.

Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM. These new MediaTek scalers will support all the same features that current dedicated G-Sync modules do. Nvidia says that three G-Sync monitors with MediaTek scaler chips inside will launch "later this year": the Asus ROG Swift PG27AQNR, the Acer Predator XB273U F5, and the AOC AGON PRO AG276QSG2. These are all 27-inch 1440p displays with maximum refresh rates of 360 Hz.

AMD agreed to buy server maker ZT Systems in a cash and stock transaction valued at $4.9 billion, adding data center technology that will bolster its efforts to challenge Nvidia. From a report: ZT Systems, based in Secaucus, New Jersey, will become part of AMD's Data Center Solutions Business Group, according to a statement Monday. AMD will retain the business's design and customer teams and look to sell the manufacturing division. Closely held ZT has extensive experience making server computers for owners of large data centers -- the kind of customers that are pouring billions into new AI capabilities. The acquisition will "significantly strengthen our data center AI systems," AMD Chief Executive Officer Lisa Su said in the statement.

"I've been somewhat okay about backing up our home data," writes long-time Slashdot reader 93 Escort Wagon.

But they could use some good advice: We've got a couple separate disks available as local backup storage, and my own data also gets occasionally copied to encrypted storage at BackBlaze. My daughter has her own "cloud" backups, which seem to be a manual push every once in a while of random files/folders she thinks are important. Including our media library, between my stuff, my daughter's, and my wife's... we're probably talking in the neighborhood of 10 TB for everything at present. The whole setup is obviously cobbled together, and the process is very manual. Plus it's annoying since I'm handling Mac, Linux, and Windows backups completely differently (and sub-optimally). Also, unsurprisingly, the amount of data we possess does seem to be increasing with time.

I've been considering biting the bullet and buying an NAS [network-attached storage device], and redesigning the entire process — both local and remote. I'm familiar with Synology and DSM from work, and the DS1522+ looks appealing. I've also come across a lot of recommendations for QNAP's devices, though. I'm comfortable tackling this on my own, but I'd like to throw this out to the Slashdot community.

What NAS do you like for home use. And what disks did you put in it? What have your experiences been?
Long-time Slashdot reader AmiMoJo asks "Have you considered just building one?" while suggesting the cheapest option is low-powered Chinese motherboards with soldered-in CPUs. And in the comments on the original submission, other Slashdot readers shared their examples:

• destined2fail1990 used an AMD Threadripper to build their own NAS with 10Gbps network connectivity.
• DesertNomad is using "an ancient D-Link" to connect two Synology DS220 DiskStations
• Darth Technoid attached six Seagate drives to two Macbooks. "Basically, I found a way to make my older Mac useful by simply leaving it on all the time, with the external drives attached."

But what's your suggestion? Share your own thoughts and experiences. What NAS do you like for home use? What disks would you put in it?

And what have your experiences been?

AMD increased its market share in data center and laptop CPU segments during Q2 2024, according to a new report from Mercury Research. The company captured 24.1% of the data center CPU market, up 0.5% from the previous quarter and 5.6% year-over-year. In laptops, AMD's share rose to 20.3%, a 1% increase quarter-over-quarter and 3.8% year-over-year. The company's revenue share in laptops reached 17.7%, indicating lower average selling prices compared to Intel.

Intel maintained its overall lead, controlling 78.9% of the client PC market. In desktops, Intel gained 1% share, now holding 77% of the market. AMD's data center revenue share hit 33.7%, suggesting higher average selling prices for its EPYC processors compared to Intel's Xeon chips. AMD earned $2.8 billion from 24.1% unit share, while Intel made $3.0 billion from 75.9% unit share.

An anonymous reader quotes a report from Wired: Security flaws in your computer's firmware, the deep-seated code that loads first when you turn the machine on and controls even how its operating system boots up, have long been a target for hackers looking for a stealthy foothold. But only rarely does that kind of vulnerability appear not in the firmware of any particular computer maker, but in the chips found across hundreds of millions of PCs and servers. Now security researchers have found one such flaw that has persisted in AMD processors for decades, and that would allow malware to burrow deep enough into a computer's memory that, in many cases, it may be easier to discard a machine than to disinfect it. At the Defcon hacker conference tomorrow, Enrique Nissim and Krzysztof Okupski, researchers from the security firm IOActive, plan to present a vulnerability in AMD chips they're calling Sinkclose. The flaw would allow hackers to run their own code in one of the most privileged modes of an AMD processor, known as System Management Mode, designed to be reserved only for a specific, protected portion of its firmware. IOActive's researchers warn that it affects virtually all AMD chips dating back to 2006, or possibly even earlier.

Nissim and Okupski note that exploiting the bug would require hackers to already have obtained relatively deep access to an AMD-based PC or server, but that the Sinkclose flaw would then allow them to plant their malicious code far deeper still. In fact, for any machine with one of the vulnerable AMD chips, the IOActive researchers warn that an attacker could infect the computer with malware known as a "bootkit" that evades antivirus tools and is potentially invisible to the operating system, while offering a hacker full access to tamper with the machine and surveil its activity. For systems with certain faulty configurations in how a computer maker implemented AMD's security feature known as Platform Secure Boot -- which the researchers warn encompasses the large majority of the systems they tested -- a malware infection installed via Sinkclose could be harder yet to detect or remediate, they say, surviving even a reinstallation of the operating system. Only opening a computer's case, physically connecting directly to a certain portion of its memory chips with a hardware-based programming tool known as SPI Flash programmer and meticulously scouring the memory would allow the malware to be removed, Okupski says. Nissim sums up that worst-case scenario in more practical terms: "You basically have to throw your computer away." In a statement shared with WIRED, AMD said it "released mitigation options for its AMD EPYC datacenter products and AMD Ryzen PC products, with mitigations for AMD embedded products coming soon."

The company also noted that it released patches for its EPYC processors earlier this year. It did not answer questions about how it intends to fix the Sinkclose vulnerability.

Intel continues to grapple with the mystery surrounding crashes in its latest 13th- and 14th-gen Core desktop processors, but it's refuting claims that the issue extends to its mobile chips. From a report: Matthew Cassells, the founder of Alderon Games and developer of Path of Titans, claimed on Reddit that the company had noted crashes on Intel's mobile processors. "Yes we have several laptops that have failed with the same crashes," he wrote. "It's just slightly more rare then [sic] the desktop CPU faults." Previously, Alderon had issued a statement blaming "thousands of crashes," as noted by its own crash reports on the Intel CPUs. It also claimed it would switch its server infrastructure to chips made by AMD.

Intel's problem with its latest Core chips has persisted since January, but simmered for months while developers began pointing fingers and PC makers started working on solutions. To date, the most bulletproof solution has been simply to swap out an affected part for a replacement, which Intel has been willing to do. Intel has also issued guidance as to what power-profile settings users and board makers should use while it works to solve the problem. An Intel representative said Friday via e-mail that Intel still remains in the dark about the root cause of the issue. However, Intel claims that its mobile processors aren't being affected.

AMD has introduced its latest Ryzen AI chips, built on the new Zen 5 architecture, in an ambitious attempt to compete with Apple's dominant MacBook processors. During a recent two-day event in Los Angeles, the company made bold claims about outperforming Apple's M3 and M3 Pro chips in various tasks including multitasking, image processing, and gaming, though these assertions remain unverified due to limited demonstrations and benchmarks provided at the event, The Verge reports. The report adds: At that event, I heard AMD brag about beating the MacBook more than I've ever heard a company directly target a competitor before. AMD claimed its new Ryzen chip "exceeds the performance of what MacBook Air has to offer in multitasking, image processing, 3D rendering, and gaming"; "is 15 percent faster than the M3 Pro" in Cinebench; and is capable of powering up to four displays, "unlike the MacBook Air, which limits you to two displays only." While AMD touted significant improvements in CPU architecture, graphics performance, and AI capabilities, journalists present at the event were unable to fully test or validate these features, leaving many questions unanswered about the chips' real-world performance.

The company's reluctance or inability to showcase certain capabilities, particularly in gaming and AI applications, has raised eyebrows among industry observers, the report adds. The new Ryzen AI chips are scheduled to debut in Asus laptops on July 28th, marking a critical juncture for AMD in the fiercely competitive laptop processor market. As Apple's M-series chips and Qualcomm's Snapdragon processors continue to gain traction in the mobile computing space, the success or failure of AMD's latest offering could have far-reaching implications for the future of x86 architecture in laptops.

Matthew Connatser reports via The Register: US government is granting GlobalWafers up to $400 million in CHIPS Act cash to help fund its 300mm wafer manufacturing facilities in Texas and Missouri. The Commerce Department said GlobalWafers' Texas plant is a significant milestone for the US as it's the country's first facility for manufacturing 300mm wafers, the kind that are used for modern processes. The Missouri site will produce a silicon-on-insulator (SOI) variant of 300mm wafers, which are more geared towards defense and aerospace applications where chips need to be less prone to failure. Plans to build the Texas wafer plant were first revealed just over two years ago by the Taiwanese chip biz. It was an alternative use of a few billion dollars that were originally earmarked for acquiring German wafer maker Siltronic, an acquisition which didn't go as hoped due to resistance from German regulators.

The Missouri plant meanwhile was announced in 2021 as a partnership between GlobalWafers and GlobalFoundries, the chip fab spun off from AMD that now focuses on older nodes rather than the cutting edge. This fab seems to be the smaller of the two, considering that its budget when first announced was just $800 million, and that seems to also cover an expansion of a 200mm SOI wafer plant. In total, GlobalWafers' Texas and Missouri factories will cost around four billion dollars, which means the maximum award funded by the CHIPS Act would cover up to ten percent of the budget. The Commerce Department claims that facilities will create 1,700 jobs in construction and 880 in manufacturing.

"The latest version of the Linux kernel adds an array of improvements," writes the blog OMG Ubuntu, " including a new memory sealing system call, a speed boost for AES-XTS encryption on Intel and AMD CPUs, and expanding Rust language support within the kernel to RISC-V." Plus, like in all kernel releases, there's a glut of groundwork to offer "initial support" for upcoming CPUs, GPUs, NPUs, Wi-Fi, and other hardware (that most of us don't use yet, but require Linux support to be in place for when devices that use them filter out)...

Linux 6.10 adds (after much gnashing) the mseal() system call to prevent changes being made to portions of the virtual address space. For now, this will mainly benefit Google Chrome, which plans to use it to harden its sandboxing. Work is underway by kernel contributors to allow other apps to benefit, though. A similarly initially-controversial change merged is a new memory-allocation profiling subsystem. This helps developers fine-tune memory usage and more readily identify memory leaks. An explainer from LWN summarizes it well.

Elsewhere, Linux 6.10 offers encrypted interactions with trusted platform modules (TPM) in order to "make the kernel's use of the TPM reasonably robust in the face of external snooping and packet alteration attacks". The documentation for this feature explains: "for every in-kernel operation we use null primary salted HMAC to protect the integrity [and] we use parameter encryption to protect key sealing and parameter decryption to protect key unsealing and random number generation." Sticking with security, the Linux kernel's Landlock security module can now apply policies to ioctl() calls (Input/Output Control), restricting potential misuse and improving overall system security.

On the networking side there's significant performance improvements to zero-copy send operations using io_uring, and the newly-added ability to "bundle" multiple buffers for send and receive operations also offers an uptick in performance...

A couple of months ago Canonical announced Ubuntu support for the RISC-V Milk-V Mars single-board computer. Linux 6.10 mainlines support for the Milk-V Mars, which will make that effort a lot more viable (especially with the Ubuntu 24.10 kernel likely to be v6.10 or newer). Others RISC-V improvements abound in Linux 6.10, including support for the Rust language, boot image compression in BZ2, LZ4, LZMA, LZO, and Zstandard (instead of only Gzip); and newer AMD GPUs thanks to kernel-mode FPU support in RISC-V.
Phoronix has their own rundown of Linux 6.10, plus a list of some of the highlights, which includes:

• The initial DRM Panic infrastructure
• The new Panthor DRM driver for newer Arm Mali graphics
• Better AMD ROCm/AMDKFD support for "small" Ryzen APUs and new additions for AMD Zen 5.
• AMD GPU display support on RISC-V hardware thanks to RISC-V kernel mode FPU
• More Intel Xe2 graphics preparations
• Better IO_uring zero-copy performance
• Faster AES-XTS disk/file encryption with modern Intel and AMD CPUs
• Continued online repair work for XFS
• Steam Deck IMU support
• TPM bus encryption and integrity protection

"Intel's problems with unstable 13th-gen and 14th-gen high-end CPUs appear to run deeper than we thought," writes TechRadar, "and a new YouTube video diving into these gremlins will do little to calm any fears that buyers of Raptor Lake Core i9 processors (and its subsequent refresh) have." Level1Techs is the YouTuber in question, who has explored several avenues in an effort to make more sense of the crashing issues with these Intel processors that are affecting some PC gamers and making their lives a misery — more so in some cases than others. Data taken from game developer crash logs — from two different games — clearly indicates a high prevalence of crashes with the mentioned more recent Intel Core i9 chips (13900K and 14900K).

In fact, for one particular type of error (decompression, a commonly performed operation in games), there was a total of 1,584 that occurred in the databases Level1Techs sifted through, and an alarming 1,431 of those happened with a 13900K or 14900K. Yes — that's 90% of those decompression errors hitting just two specific CPUs. As for other processors, the third most prevalent was an old Intel Core i7 9750H (Coffee Lake laptop CPU) — which had a grand total of 11 instances. All AMD processors in total had just 4 occurrences of decompression errors in these game databases.
"In case you were thinking that AMD chips might be really underrepresented here, hence that very low figure, well, they're not — 30% of the CPUs in the database were from Team Red..."

"The YouTuber also brings up another point here: namely that data centers are noticing these issues with Core i9s."
