Apple has pushed out security updates that it says are "recommended for all users," after fixing a pair of security bugs used in active cyberattacks targeting Mac users. From a report: In a security advisory on its website, Apple said it was aware of two vulnerabilities that "may have been actively exploited on Intel-based Mac systems." The bugs are considered "zero day" vulnerabilities because they were unknown to Apple at the time they were exploited.

[...] The vulnerabilities were reported by security researchers at Google's Threat Analysis Group, which investigates government-backed hacking and cyberattacks, suggesting that a government actor may be involved in the attacks.

Slashdot unixbhaskar writes: Linus has released a fresh Linux kernel for public consumption. Please give it a try and report any glitches to the maintainers for improvement. Also, please do not forget to express your appreciation to those tireless folks who did all the hard work for you.
The blog OMG Ubuntu calls it "one of the most biggest kernel releases for a while," joking that it's a "really real-time kernel." The headline feature in Linux 6.12 is mainline support for PREEMPT_RT. This patch set dramatically improves the performance of real-time applications by making kernel processes pre-emptible — effectively enabled proper real-time computing... Meanwhile, Linus Torvalds himself contributes a new method for user-space address masking designed to claw back some of the performance lost due to Spectre-v1 mitigations.

You might have heard that kernel devs have been working to add QR error codes to Linux's kernel panic BSOD screen (as a waterfall of error text is often cut off and not easily copied for ad-hoc debugging). Well, Linux 6.12 adds support for those during Direct Rendering Manager panics...

A slew of new RISC-V CPU ISA extensions are supported in Linux 6.12; hybrid CPU scaling in the Intel P-State driver lands ahead of upcoming Intel Core Ultra 2000 chips; and AMD P-State driver improves AMD Boost and AMD Preferred Core features.
More coverage from the blog 9to5Linux highlights a new scheduler called sched_ext, Clang support (including LTO) for nolibc, support for NVIDIA's virtual command queue implementation for SMMUv3, and "an updated cpuidle tool that now displays the residency value of cpuidle states for a clearer and more detailed view of idle state information when using cpuidle-info." Linux kernel 6.12 also introduces SWIG bindings for libcpupower to make it easier for developers to write scripts that use and extend the functionality of libcpupower, support for translating normalized error addresses reported by an AMD memory controller into system physical addresses using a UEFI mechanism called platform runtime mechanism (PRM), as well as simplified loading of microcode patches on AMD Zen and newer CPUs by using the family, model, and stepping encoded in the patch revision number...

Moreover, Linux 6.12 adds support for running as a protected guest on Android as well as perf and support for a bunch of new interconnect PMUs. It also adds the final conversions to the new Intel VFM CPU model matching macros, rewrites the PCM buffer allocation handling and locking optimizations, and improves the USB audio driver...

An anonymous reader shared this report from Phoronix: Intel's Linux kernel test robot has reported a 3888.9% performance improvement in the mainline Linux kernel as of this past week...

Intel thankfully has the resources to maintain this automated service for per-kernel commit/patch testing and has been maintaining their public kernel test robot for years now to help catch performance changes both positive and negative to the Linux kernel code. The commit in question causing this massive uplift to performance is mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes. The patch message confirms it will fix some prior performance regressions and deliver some major uplift in specialized cases...

That mmap patch merged last week affects just one line of code.
This week the Register also reported that Linus Torvalds revised a previously-submitted security tweak that addressed Spectre and Meltdown security holes, writing in his commit message that "The kernel test robot reports a 2.6 percent improvement in the per_thread_ops benchmark."

An anonymous reader shares a report: AMD has gained a substantial 5.7 percentage points of share of the desktop x86 CPU market in the third quarter compared to Q2, the largest quarterly share gain since we began tracking the market share reports in 2016. It also represents an incredible ten percentage point improvement over the prior year. AMD also raked in a strong increase in revenue share, jumping 8.5 percentage points over the prior quarter, indicating that it is selling a strong mix of higher-end CPU models.

During the quarter, AMD launched its new Ryzen 9000-series family of processors amid a scandal related to stability issues with Intel's Raptor Lake chips, which generated a flood of negative press for the company over the course of several months, and inventory adjustments for one of Intel's customers. AMD now commands 28.7% of the desktop processor market. AMD also continued to gain share in the laptop and server markets, though its gains on the desktop side of the business were the most impressive, according to Mercury Research.

An anonymous reader quotes a report from Oregon Live: Intel told employees this week that it will bring back free coffee and tea at its work sites, one of many benefits the chipmaker eliminated last summer as it sought to slash $10 billion from its annual budget. "Although Intel still faces cost challenges, we understand that small comforts play a significant role in our daily routines," Intel wrote on its internal messaging forum, called Circuit. "We know this is a small step, but we hope it is a meaningful one in supporting our workplace culture." Intel declined comment. The company did not resume offering free fruit, another perk eliminated last summer. Employees say privately that morale has been devastated by Intel's poor financial performance and by cutbacks aimed at returning the business to profitability.

[...] Christy Pambianchi, Intel's chief people officer, told employees that Intel had been spending $100 million annually on free and discounted food and beverages and couldn't afford to keep doing that. "Until we get into a better financial health position, we need to be suspending those," Pambianchi said, according to an account of the meeting reviewed by The Oregonian/OregonLive. By Wednesday the company had reversed itself, committing to keep its employees caffeinated. In August, Intel announced plans to lay off over 16,000 employees, representing more than 15% of its global workforce. Its stock dropped to a 50-year low following the announcement. Starting November 8, Nvidia will replace the chipmaker on the Dow Jones Industrial Average.

According to Deadline's Mike Fleming Jr, Lucasfilm is developing a new Star Wars trilogy. It will be written by Simon Kinberg, who will also produce the films alongside Lucasfilm chief Kathleen Kennedy. From the report: I heard this will comprise Episodes 10-12 of The Skywalker Saga that began with George Lucas's 1977 first film, which, along with Steven Spielberg's Jaws, reshaped the global blockbuster game. Insiders disputed my intel that Kinberg will continue that storyline, saying this instead will begin a new saga, and sit alongside percolating Star Wars projects with James Mangold, Sharmeen Obaid-Chinoy, Taika Waititi and Donald Glover. As usual, Lucasfilm and Disney are not commenting.

Kinberg previously worked with Lucasfilm in co-creating with Dave Filoni and Carrie Beck the Emmy-nominated animated series Star Wars Rebels that ran for four seasons from 2014-2018. He was also a consultant on Star Wars Episode VII: The Force Awakens, the J.J. Abrams-directed film that revived the franchise in 2015. He has also been heavily involved in other franchises as writer and/or producer.

Intel faces a class-action lawsuit alleging its 13th and 14th generation desktop processors from 2022 and 2023 are defective, causing system instability and frequent crashes. The suit claims that Intel knew of the issue but continued marketing the processors anyway. The Register reports: The plaintiff, Mark Vanvalkenburgh of Orchard Park, New York, purchased an Intel Core i7-13700K from Best Buy in January 2023, according to the complaint [PDF]. "After purchasing the product, Plaintiff learned that the processor was defective, unstable, and crashing at high rates," the complaint claims. "The processor caused issues in his computer, including random screen blackouts and random computer restarts. These issues were not resolved even after he attempted to install a patch issued by Intel for its 13th Generation processors."

The potential class-action lawsuit cites various media reports and social media posts dating back to December 2022 that describe problems with Intel's 13th and 14th generation processors, known as Raptor Lake. These reports document unexplained failures and system instability, as well as a higher-than-expected rate of product returns. "By late 2022 or early 2023, Intel knew of the defect," the complaint says. "Intel's Products undergo pre-release and post-release testing. Through these tests, Intel became aware of the defect in the processors." And because Intel continued making marketing claims touting the speed and performance of its products, with no mention of any defect, the complaint alleges that Intel committed fraud by omission, breached implied warranty, and violated New York General Business Law.

"AMD's Ryzen 7 9800X3D debuts with impressive performance gains, powered by advanced 3D V-Cache technology and improved thermal efficiency," writes Slashdot reader jjslash. "While the CPU shines as a top choice right out of the gate, AMD's history of quick price cuts suggests waiting could yield even better value for savvy buyers." TechSpot reports: Today we're finally able to show you how AMD's new Ryzen 7 9800X3D performs, and spoiler alert -- it's a real weapon that solves the issues we encountered with the non-3D Zen 5 chips before this. Without question, this is the best CPU released since the 7800X3D, making this launch particularly exciting. [...] For now, the 9800X3D is mighty impressive, the undisputed king of gaming, and it marks a historic milestone. We don't think AMD has ever been this dominant over Intel, certainly not in the last 15 years.

AMD has surpassed Intel in datacenter processor sales for the first time in history, marking a dramatic shift in the server chip market. AMD's datacenter revenue hit $3.549 billion in Q3, edging out Intel's $3.3 billion, according to SemiAnalysis.

The milestone ends Intel's decades-long dominance in server processors, where it held over 90% market share until recent years. AMD's EPYC processors now power many high-end servers, commanding premium prices despite selling at lower costs than comparable Intel chips.

In 1896 the Dow Jones Industrial Average (or DJIA) was created as a kind of proxy indicator for the wider stock market. "A stock is typically added only if the company has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors," according to a source cited by Yahoo Finance. Its mix of stocks might be informally considered a sign of the times, since it's made up of 30 stocks that according to Wikipedia have been changed only 57 times over the last 128 years.

Wait — make that 58.... CNBC reports that NVIDIA is replacing Intel in the DJIA, "a shakeup to the blue-chip index that reflects the boom in AI and a major shift in the semiconductor industry." Companies including Microsoft, Meta, Google and Amazon are purchasing Nvidia's GPUs, such as the H100, in massive quantities to build clusters of computers for their AI work. Nvidia's revenue has more than doubled in each of the past five quarters, and has at least tripled in three of them. The company has sginaled that demand for its next-generation AI GPU called Blackwell is "insane...."

While Nvidia has been soaring, Intel has been slumping. Long the dominant maker of PC chips, Intel has lost market share to Advanced Micro Devices and has made very little headway in AI. Intel shares have fallen by more than half this year as the company struggles with manufacturing challenges and new competition for its central processors. Intel said in a filing this week that the board's audit and finance committee approved cost and capital reduction activities, including lowering head count by 16,500 employees and reducing its real estate footprint. The job cuts were originally announced in August."
The DJIA will now include four of six tech companies worth $1 trillion — Apple, Microsoft, NVIDIA, and Amazon (which joined in February, replacing the owners of the Walgreens pharmacy chain). The other two trillion-dollar tech companies (not included in the DJIA) are Meta and Alphabet.

Adding NVIDIA to the DJIA will ensure "more representative exposure to the semiconductors industry" within the average, the index's curators told the Washington Post.

And also leaving the DJIA is power-generation company AES (which according to CNBC had a power mix of 54% renewables, 27% natural gas, 17% coal). It will be replaced by Vistra, defined by Wikipedia as America's largest competitive power generator, "with a capacity of approximately 39GW powered by a diverse portfolio including natural gas, nuclear, solar, and battery energy storage facilities." In the 2020 Forbes Global 2000, Vistra Energy was ranked as the 756th-largest public company in the world. The company owns the Moss Landing Power Plant in California which currently (2021) contains the largest battery energy storage system in the world (400-MW/1,600-MWh). As of 2020, the company was ranked as the highest CO2 emitter in the U.S.

Intel is rolling back one of the biggest changes to its laptop chips in years. The Verge: Remember how this fall's Lunar Lake laptops ditched the idea of memory sticks, putting a fixed amount of RAM on the processor package instead? Intel CEO Pat Gelsinger now says that turned out to be a financial mistake, and Intel won't do it again. Oh, and he may be axing desktop GPUs, too. Future Intel generations of chips, including Panther Lake and Nova Lake, won't have baked-on memory. "It's not a good way to run the business, so it really is for us a one-off with Lunar Lake," said Gelsinger on Intel's Q3 2024 earnings call, as spotted by VideoCardz.

"Nvidia dethroned Apple as the world's most valuable company on Friday..." reports Reuters, "powered by insatiable demand for its specialized artificial intelligence chips." Nvidia's stock market value briefly touched $3.53 trillion, slightly above Apple's $3.52 trillion, LSEG data showed...

The EU Court of Justice ruled in favor of Intel, dismissing the European Commission's appeal and ending a nearly two-decade-long case over allegations that Intel's rebates to computer makers were anticompetitive. Reuters reports: The European Commission had fined Intel for giving rebates to computer makers Dell, Hewlett-Packard and Lenovo for buying most of their chips from Intel, which regulators said was an attempt to block Advanced Micro Devices. Regulators generally oppose rebates offered by dominant companies because they fear they may be anticompetitive, while companies say enforcers must prove discounts have anticompetitive effects before companies are sanctioned.

EU regulators had initially fined Intel 1.06 billion euros ($1.14 billion) but a lower tribunal scrapped that. Intel's case was boosted earlier this year when an adviser to the court said regulators had not properly performed an economic analysis.

MojoKid writes: Intel has lifted the embargo on independent reviews of its new Core Ultra 200S series Arrow Lake-S processors, which mark a shift in its desktop CPU strategy with symmetrical core/thread counts (no Hyperthreading) and a dedicated 13 TOPS NPU. This series features a disaggregated tiled design for the first time in Intel's desktop chips, focusing on efficiency and power reduction. The Core Ultra 5 245, priced around $300, and the Ultra 9 285K at $589 deliver strong performance, particularly in creator workloads, competing well with AMD's Ryzen CPUs, while the Ultra 9 285K's price undercuts AMD's Ryzen 9 9950X significantly. While gaming performance shows slight regression in spots, the new chips are much more power-efficient than their predecessors. Overall, the platform offers leading-edge features, competitive pricing, and solid performance for creators, gamers and workstation pros.

The White House is directing the Pentagon and intelligence agencies to increase their adoption of AI, expanding the Biden administration's efforts to curb technological competition from China and other adversaries. From a report: The edict is part of a landmark national security memorandum published Thursday. It aims to make government agencies step up experiments and deployments of AI. The memo also bans agencies from using the technology in ways that "do not align with democratic values," according to a White House news release.

"This is our nation's first ever strategy for harnessing the power and managing the risks of AI to advance our national security," national security adviser Jake Sullivan said in a speech Thursday. Sullivan called the speed of change in AI "breathtaking" and said it had the potential to affect fields ranging from nuclear physics to rocketry and stealth technology. The White House believes that providing clear rules for using AI will make it easier for government agencies to use the technology, according to a briefing with senior administration officials who spoke on the condition of anonymity to discuss details of the report before its publication.

Intel considered acquiring graphics chip maker Nvidia for up to $20 billion in 2005, a move that could have reshaped the AI industry, according to The New York Times. Then-CEO Paul Otellini pitched the acquisition to Intel's board, recognizing the potential of graphics processors for data center computing. The board rejected the proposal, citing Intel's poor track record with acquisitions and the deal's unprecedented size, the report added. Today, Nvidia dominates the AI chip market with a $3 trillion valuation, while Intel struggles with declining revenue and recent layoffs of 16,000 workers.

Intel and Boeing, once exemplars of American manufacturing prowess, now face existential crises. Their market values have plummeted, jeopardizing not just shareholder wealth but national security. The U.S. is losing its edge in manufacturing high-tech products, crucial in its geopolitical contest with China, a story on WSJ argues.

Unlike past manufacturing declines, Intel and Boeing's woes stem from internal missteps, prioritizing financial performance over engineering excellence. Their potential demise threatens America's semiconductor and commercial aircraft industries, with far-reaching consequences for the nation's technological ecosystem. While government intervention is controversial, national security concerns may necessitate support. WSJ adds: So, much as national leaders would like to ignore these companies' woes, they can't. National security dictates the U.S. maintain some know-how in making aircraft and semiconductors.

Certainly other countries feel that way: European governments heavily subsidized Airbus. China is pursuing dominance in key technologies regardless of the cost. Its so-called Big Fund has sunk roughly $100 billion into semiconductors while aid to Comac had reached $72 billion in 2020, according to the Center for Strategic and International Studies.

"Until Comac succeeds in gaining significant global market share, it will continue to run big losses and be bailed out by the Chinese government," said Atkinson, whose organization gets support from Boeing.

Both political parties have bought into the idea that manufacturing is special and thus deserving of public support. That raises the question: which manufacturing, and what kind of support?

The goal of manufacturing strategy shouldn't be just producing jobs but great, world-beating products. [...]

Libreboot is a distribution of coreboot "aimed at replacing the proprietary BIOS firmware contained by most computers."

So then what exactly is GNU Boot? Its home page explains... In November 2022, Libreboot began to include non-libre code. We have made repeated efforts to continue collaboration with those developers to help their version of Libreboot remain libre, but that was not successful. Now we've stepped forward to stand up for freedom, ours and that of the wider community, by maintaining our own version — a genuinely libre Libreboot, that after some hurdles gave birth to this project: GNU Boot.
But today, Phoronix writes: While priding itself on being "100% free", last December [GNU Boot] had to drop some motherboard support and CPU code after discovering they were shipping some files that are non-free by their free software standards. Today they announced another mistake in having inadvertently been shipping additional non-free code.

GNU Boot discovered an issue with non-free code affecting not only them but also some of the Linux distributions that pride themselves on being fully free software / 100% open-source. This latest snafu they say is "more problematic" than their prior non-free code discover due to impacting the free software Linux distributions too. The issue at hand though comes down to test data contained within the archive and that containing non-free code in the form of microcode, BIOS bits, and Intel Management Engine firmware.
"We also contacted Replicant..." according to the announcement, "a free Android distro that also ships vboot source code." And in addition, "We had to re-release all the affected tarballs." (Which at this point is three release candidates...)

Tom's Hardware reports on some interesting hardware history being shared on X.com: AMD engineer Phil Park identified a curious nugget of PC architectural history from, of all places, a year-old Quora answer posted by former Intel engineer [and Pentium Pro architect] Robert Colwell. The nugget indicates that Intel could have beaten AMD to the x86-64 punch if the former wasn't dead-set on the x64-only Itanium line of CPUs.
Colwell had responded on Quora to the question "Shouldn't Intel with its vast resources have been able to develop both architectures?" This was a marketing decision by Intel — they believed, probably rightly, that bringing out a new 64-bit feature in the x86 would be perceived as betting against their own native-64-bit Itanium, and might well severely damage Itanium's chances. I was told, not once, but twice, that if I "didn't stop yammering about the need to go 64-bits in x86 I'd be fired on the spot" and was directly ordered to take out that 64-bit stuff. I decided to split the difference, by leaving in the gates but fusing off the functionality. That way, if I was right about Itanium and what AMD would do, Intel could very quickly get back in the game with x86. As far as I'm concerned, that's exactly what did happen.
Phil Park continued the discussion on X.com. "He didn't quite get what he wanted, but he got close since they had x86-64 support in subsequent products when Intel made their comeback." (So, Park posted later in the thread, "I think he won the long game.")

Park also shared a post from Nicholas Wilt (NVIDIA CUDA designer who earlier did GPU computing work at Microsoft and built the prototype for Windows Desktop Manager): I have an x86-64 story of my own. I pressed a friend at AMD to develop an alternative to Itanium. "For all the talk about Wintel," I told him, "these companies bear no love for one another. If you guys developed a 64-bit extension of x86, Microsoft would support it...."

Interesting coda: When it became clear that x86-64 was beating Itanium in the market, Intel reportedly petitioned Microsoft to change the architecture and Microsoft told Intel to pound sand.

"Six years after the Spectre transient execution processor design flaws were disclosed, efforts to patch the problem continue to fall short," writes the Register: Johannes Wikner and Kaveh Razavi of Swiss University ETH Zurich on Friday published details about a cross-process Spectre attack that derandomizes Address Space Layout Randomization and leaks the hash of the root password from the Set User ID (suid) process on recent Intel processors. The researchers claim they successfully conducted such an attack.... [Read their upcomong paper here.] The indirect branch predictor barrier (IBPB) was intended as a defense against Spectre v2 (CVE-2017-5715) attacks on x86 Intel and AMD chips. IBPB is designed to prevent forwarding of previously learned indirect branch target predictions for speculative execution. Evidently, the barrier wasn't implemented properly.

"We found a microcode bug in the recent Intel microarchitectures — like Golden Cove and Raptor Cove, found in the 12th, 13th and 14th generations of Intel Core processors, and the 5th and 6th generations of Xeon processors — which retains branch predictions such that they may still be used after IBPB should have invalidated them," explained Wikner. "Such post-barrier speculation allows an attacker to bypass security boundaries imposed by process contexts and virtual machines." Wikner and Razavi also managed to leak arbitrary kernel memory from an unprivileged process on AMD silicon built with its Zen 2 architecture.

Videos of the Intel and AMD attacks have been posted, with all the cinematic dynamism one might expect from command line interaction.

Intel chips — including Intel Core 12th, 13th, and 14th generation and Xeon 5th and 6th — may be vulnerable. On AMD Zen 1(+) and Zen 2 hardware, the issue potentially affects Linux users. The relevant details were disclosed in June 2024, but Intel and AMD found the problem independently. Intel fixed the issue in a microcode patch (INTEL-SA-00982) released in March, 2024. Nonetheless, some Intel hardware may not have received that microcode update. In their technical summary, Wikner and Razavi observe: "This microcode update was, however, not available in Ubuntu repositories at the time of writing this paper." It appears Ubuntu has subsequently dealt with the issue.

AMD issued its own advisory in November 2022, in security bulletin AMD-SB-1040. The firm notes that hypervisor and/or operating system vendors have work to do on their own mitigations. "Because AMD's issue was previously known and tracked under AMD-SB-1040, AMD considers the issue a software bug," the researchers explain. "We are currently working with the Linux kernel maintainers to merge our proposed software patch."
BleepingComputer adds that the ETH Zurich team "is working with Linux kernel maintainers to develop a patch for AMD processors, which will be available here when ready."
