Intel is going to be disabling Transactional Synchronization Extensions (TSX) by default for various Skylake through Coffee Lake processors with forthcoming microcode updates. Phoronix reports: Transactional Synchronization Extensions (TSX) have been around since Haswell for hardware transactional memory support and going off Intel's own past numbers can be around 40% faster in specific workloads or as much 4~5 times faster in database transaction benchmarks. TSX issues have been found in the past such as a possible side channel timing attack that could lead to KASLR being defeated and CVE-2019-11135 (TSX Async Abort) for an MDS-style flaw. Now in 2021 Intel is disabling TSX by default across multiple families of Intel CPUs from Skylake through Coffee Lake. [...] The Linux kernel is preparing for this microcode change as seen in the flow of new patches this morning for the 5.14 merge window.

A memory ordering issue is what is reportedly leading Intel to now deprecate TSX on various processors. There is this Intel whitepaper (PDF) updated this month that outlines the problem at length. As noted in the revision history, the memory ordering issue has been known to Intel since at least before October 2018 but only now in June 2021 are they pushing out microcode updates to disable TSX by default. With forthcoming microcode updates will effectively deprecate TSX for all Skylake Xeon CPUs prior to Stepping 5 (including Xeon D and 1st Gen Xeon Scalable), all 6th Gen Xeon E3-1500m v5 / E3-1200 v5 Skylake processors, all 7th/8th Gen Core and Pentium Kaby/Coffee/Whiskey CPUs prior to 0x8 stepping, and all 8th/9th Gen Core/Pentium Coffee Lake CPUs prior to 0xC stepping will be affected. That ultimately spans from various Skylake steppings through Coffee Lake; it was with 10th Gen Comet Lake and Ice Lake where TSX/TSX-NI was subsequently removed.

In addition to disabling TSX by default and force-aborting all RTM transactions by default, a new CPUID bit is being enumerated with the new microcode to indicate that the force aborting of RTM transactions. It's due to that new CPUID bit that the Linux kernel is seeing patches. Previously Linux and other operating systems applied a workaround for the TSX memory ordering issue but now when this feature is disabled, the kernel can drop said workaround. These patches are coming with the Linux 5.14 cycle and will likely be back-ported to stable too.

Neowin: Microsoft today released the first-ever Windows 11 build to Insiders in the Dev channel, bringing build 22000.51. While most of the announced features made it to the build, there are a few missing ones such as support for Android apps. The firm also posted a few known issues for the release. In addition to the build, the company has also posted clarification about the confusion surrounding the minimum system requirements.

The firm starts off by acknowledging that there has been confusion caused by the PC Health Check tool, something that was updated late last week after negative feedback from users about the lack of clarity on Windows 11 compatibility. It says that the tool was "not fully prepared to share the level of detail or accuracy you expected from us on why a Windows 10 PC doesn't meet upgrade requirements," which is why the company is taking down the tool to address the feedback, adding that the tool will be "back online" later in the fall, closer to the general availability of Windows 11. In a blog post, the company adds: [...] Using the principles above, we are confident that devices running on Intel 8th generation processors and AMD Zen 2 as well as Qualcomm 7 and 8 Series will meet our principles around security and reliability and minimum system requirements for Windows 11. As we release to Windows Insiders and partner with our OEMs, we will test to identify devices running on Intel 7th generation and AMD Zen 1 that may meet our principles.

"Linus Torvalds has just released the Linux 5.13 kernel as stable," reports Phoronix: Linux 5.13 brings initial but still early support for the Apple M1 with basic support but not yet accelerated graphics and a lot more to iron out moving ahead. There are also new Linux 5.13 security features like the Landlock security module, Clang control flow integrity support, and optionally randomizing the kernel stack offset at each system call. There is also AMD fun this cycle around FreeSync HDMI support, initial Aldebaran bring-up, and more. Intel has more work on Alder Lake, a new cooling driver, and more discrete graphics bring-up. There are also other changes for Linux 5.13 around faster IO_uring, a generic USB display driver, and other new hardware enablement.
"5.13 overall is actually fairly large," Linus Torvalds posted on the Linux Kernel Mailing List, calling it "one of the bigger 5.x releases, with over 16,000 commits (over 17k if you count merges), from over 2,000 developers. But it's a "big all over" kind of thing, not something particular that stands out as particularly unusual..."

Slashdot reader thegarbz writes: While a lot of focus has been on the TPM requirements for Windows 11, Microsoft has since updated its documentation to provide a complete list of supported processors. At present the list includes only Intel 8th Generation Core processors or newer, and AMD Ryzen Zen+ processors or newer, effectively limiting Windows 11 to PC less than 4-5 years old.

Notably absent from the list is the Intel Core i7-7820HQ, the processor used in Microsoft's current flagship $3500+ Surface Studio 2. This has prompted many threads on Reddit from users angry that their (in some cases very new) Surface PC is failing the Windows 11 upgrade check.
The Verge confirms: Windows 11 will only support 8th Gen and newer Intel Core processors, alongside [Intel's 2016-era] Apollo Lake and newer Pentium and Celeron processors. That immediately rules out millions of existing Windows 10 devices from upgrading to Windows 11... Windows 11 will also only support AMD Ryzen 2000 and newer processors, and 2nd Gen or newer [AMD] EPYC chips. You can find the full list of supported processors on Microsoft's site...

Originally, Microsoft noted that CPU generation requirements are a "soft floor" limit for the Windows 11 installer, which should have allowed some older CPUs to be able to install Windows 11 with a warning, but hours after we published this story, the company updated that page to explicitly require the list of chips above.

Many Windows 10 users have been downloading Microsoft's PC Health App (available here) to see whether Windows 11 works on their systems, only to find it fails the check... This is the first significant shift in Windows hardware requirements since the release of Windows 8 back in 2012, and the CPU changes are understandably catching people by surprise.

Microsoft is also requiring a front-facing camera for all Windows 11 devices except desktop PCs from January 2023 onwards.
"In order to run Windows 11, devices must meet the hardware specifications," explains Microsoft's official compatibility page for Windows 11.

"Devices that do not meet the hardware requirements cannot be upgraded to Windows 11."

An anonymous reader shares a report: Today's announcement from SiFive comes in two parts; this part is significant as it recognizes that Intel will be enabling SiFive's IP portfolio on its 7nm manufacturing process for upcoming foundry customers. We are expecting Intel to offer a wide variety of its own IP, such as some of the x86 cores, memory controllers, PCIe controllers, and accelerators, however the depth of its third party IP support has not been fully established at this point. SiFive's IP is the first (we believe) official confirmation of specific IP that will be supported. Announced earlier this year by Pat Gelsinger, Intel Foundry Services (or IFS) is one prong of Intel's strategy to realign itself with the current and future semiconductor market. Despite having attempted to become a foundry player in the past, whereby they build chips under contract for their customers, it hasn't really worked out that well -- however IFS is a new reinvigoration of that idea, this time with more emphasis on getting it right and expanding the scope.

A group of seven tech companies urged the Securities and Exchange Commission to require businesses to regularly disclose climate-related matters to their shareholders. From a report: In a letter to SEC Chairman Gary Gensler on Friday, Google parent Alphabet, Amazon, Autodesk, eBay, Facebook, Intel and Salesforce shared their view in response to a request for public input on such disclosures. The tech industry has been vocal on climate issues in the past, even as employees have pressed the companies themselves to do better. "We believe that climate disclosures are critical to ensure that companies follow through on stated climate commitments and to track collective progress towards addressing global warming and building a prosperous, resilient zero-carbon economy," the companies wrote.

Apple is finally adding support for Windows Precision Touchpad drivers in its latest Boot Camp update. The new 6.1.15 update includes support for Windows Precision Touchpad, including single tap to click, lower-right corner to right-click, down motion to scroll up, and three or four finger gestures. From a report: Various Reddit users noticed the surprise update went live yesterday, and it apparently works better than third-party solutions like Trackpad++ and mac-precision-touchpad that people have had to use for years. "Works way better than both of them with better palm and thumb detection too," says one Reddit user. Microsoft first started introducing Windows Precision Touchpad with Intel in 2013, in an effort to fix what were notorious PC trackpad issues at the time. It has taken Apple a long time to enable Windows Precision Touchpad in Boot Camp, but not every MacBook is supported. An Apple support document notes that only Mac computers with a T2 chip will be able to access Windows Precision Touchpad, which is most MacBook Air and MacBook Pro models from 2018 onward.

AmiMoJo shares a report from Phoronix: The Linux x86/x86_64 kernel code already had logic in place for reserving portions of the first 1MB of RAM to avoid the BIOS or kernel potentially clobbering that space among other reasons while now Linux 5.13 is doing away with that 'wankery' and will just unconditionally always reserve the first 1MB of RAM. The Linux kernel was already catering to Intel Sandy Bridge graphics accessing memory below the 1MB mark, the first 64K of memory are known to be corrupted by some BIOSes, and similar problems coming up in that low area of memory. But rather than dealing with all that logic and other possible niche cases besides the EGA/VGA frame-buffer and BIOS, the kernel is playing it safe and just always reserving the first 1MB of RAM so it will not get clobbered by the kernel.

Several of macOS Monterey's features won't be available to users with an Intel-powered Macs.

4. More detailed maps in cities like San Francisco, Los Angeles, New York, and London in the Maps app
5. Text-to-speech in more languages, including Swedish, Danish, Norwegian, and Finnish
6. On-device keyboard dictation that performs all processing completely offline
7. Unlimited keyboard dictation (previously limited to 60 seconds per instance)

Long-time Slashdot reader Dputiger writes: Go looking for the difference between x86 and ARM CPUs, and you'll run into the idea of CISC versus RISC immediately. But 40 years after the publication of David Patterson and David Ditzel's 1981 paper, "The Case for a Reduced Instruction Set Computer," CISC and RISC are poor top-level categories for comparing these two CPU families.
ExtremeTech writes:
The problem with using RISC versus CISC as a lens for comparing modern x86 versus ARM CPUs is that it takes three specific attributes that matter to the x86 versus ARM comparison — process node, microarchitecture, and ISA — crushes them down to one, and then declares ARM superior on the basis of ISA alone. The ISA-centric argument acknowledges that manufacturing geometry and microarchitecture are important and were historically responsible for x86's dominance of the PC, server, and HPC market. This view holds that when the advantages of manufacturing prowess and install base are controlled for or nullified, RISC — and by extension, ARM CPUs — will typically prove superior to x86 CPUs.

The implementation-centric argument acknowledges that ISA can and does matter, but that historically, microarchitecture and process geometry have mattered more. Intel is still recovering from some of the worst delays in the company's history. AMD is still working to improve Ryzen, especially in mobile. Historically, both x86 manufacturers have demonstrated an ability to compete effectively against RISC CPU manufacturers.

Given the reality of CPU design cycles, it's going to be a few years before we really have an answer as to which argument is superior. One difference between the semiconductor market of today and the market of 20 years ago is that TSMC is a much stronger foundry competitor than most of the RISC manufacturers Intel faced in the late 1990s and early 2000s. Intel's 7nm team has got to be under tremendous pressure to deliver on that node.

Nothing in this story should be read to imply that an ARM CPU can't be faster and more efficient than an x86 CPU.

A California man has filed for a class action lawsuit against PC manufacturer Dell, claiming that the company "intentionally misled and deceived" buyers of its Alienware Area 51-m R1 gaming laptop, which was advertised to be more upgradeable than other gaming notebooks. From a report: The plaintiff, Robert Felter, who is based in San Francisco, alleges that Dell misleads customers to believe that the laptop would be upgradeable, possibly into future generations of components. The case, Felter v. Dell Technologies, Inc. (3:21-cv-04187) has been filed with the United States District Court in the Northern District of California. The Alienware Area 51-m was announced at CES 2019 and launched soon after. (The complaint claims the announcement was made in the summer of 2019, which is incorrect.). Among the Area 51-m's biggest touted innovations were a user-replaceable CPU and GPU.

At media briefings, Alienware representatives told the press that the CPU could be upgraded as long as it used Intel's Z390 chipset. The laptop used Intel's 9th Gen Core desktop processors, up to the Intel Core i9-9900K. Dell developed separate proprietary Dell Graphics Form Factor (DGFF) modules for the Nvidia graphics. The lawsuit, however, claims that consumers were told that "core components" (meaning the CPU and GPU) could be replaced beyond the current generation of hardware. "Dell's advertisement to the public didn't place any restrictions on the upgradeability of the laptop," lawyer David W. Kani said in an email to Tom's Hardware. "They also never disclosed that those with the highest spec CPU and/or GPU that their device would not be upgradeable."

Intel Corp's CEO said on Monday it could take several years for a global shortage of semiconductors to be resolved, a problem that has shuttered some auto production lines and is also being felt in other areas, including consumer electronics. From a report: Pat Gelsinger told a virtual session of the Computex trade show in Taipei that the work-and-study-from-home trend during the COVID-19 pandemic had led to a "cycle of explosive growth in semiconductors" that has placed huge strain on global supply chains. "But while the industry has taken steps to address near term constraints it could still take a couple of years for the ecosystem to address shortages of foundry capacity, substrates and components." Gelsinger had told The Washington Post in an interview in mid-April the shortage was going to take âoea couple of yearsâ to abate, and that it planned to start producing chips within six to nine months to address shortages at U.S. car plants.

Intel made a splash earlier in May with the launch of its first 11th Gen Tiger Lake H-series processors for more powerful laptops, but at Computex 2021, the company is also announcing a pair of new U-series chips -- one of which marks the first 5.0GHz clock speed for the company's U-series lineup of lower voltage chips. From a report: Specifically, Intel is announcing the Core i7-1195G7 -- its new top of the line chip in the U-series range -- and the Core i5-1155G7, which takes the crown of Intel's most powerful Core i5-level chip, too. Like the original 11th Gen U-series chips, the new chips operate in the 12W to 28W range. Both new chips are four core / eight thread configurations, and feature Intel's Iris Xe integrated graphics (the Core i7-1195G7 comes with 96 EUs, while the Core i5-1155G7 has 80 EUs.)

The Core i7-1195G7 features a base clock speed of 2.9GHz, but cranks up to a 5.0GHz maximum single core speed using Intel's Turbo Boost Max 3.0 technology. The Core i5-1155G7, on the other hand, has a base clock speed of 2.5GHz and a boosted speed of 4.5GHz. Getting to 5GHz out of the box is a fairly recent development for laptop CPUs, period: Intel's first laptop processor to cross the 5GHz mark arrived in 2019.

An anonymous reader quotes a report from Ars Technica: Video game and hardware studio Valve has been secretly building a Switch-like portable PC designed to run a large number of games on the Steam PC platform via Linux -- and it could launch, supply chain willing, by year's end. Multiple sources familiar with the matter have confirmed that the hardware has been in development for some time, and this week, Valve itself pointed to the device by slipping new hardware-related code into the latest version of Steam, the company's popular PC gaming storefront and ecosystem.

On Tuesday, SteamDB operator Pavel Djundik spotted the change in Steam's code, which pointed to a new device named "SteamPal." The name is a derivative of a previously discovered code term, "Neptune," which began appearing in September of last year and came with a "Neptune Optimized Games" string. At the time, curious code crawlers thought this discovery referred to some type of controller. Technically, that's true. The "SteamPal," whose name we're putting in scare quotes because we do not have confirmation of the device's final name, is an all-in-one PC with gamepad controls and a touchscreen. In other words, it looks and functions like a Nintendo Switch (albeit without removable "Joy-Con" controller functionality).

The SteamPal will [feature] a system on a chip likely coming from either Intel or AMD, not Nvidia. (The aforementioned Switch-like PC manufacturers have leaned on both AMD and Intel for their products.) It's unclear whether Valve will release multiple SKUs to offer customers a choice of power level, battery life, and other specs, as other Switch-like PCs have offered over the past year. At least one SteamPal prototype version is quite wide compared to the Nintendo Switch. This extra width accommodates a slew of control options. No, Valve is likely not slapping an entire QWERTY keyboard onto its system, but the company has packed in a standard array of gamepad buttons and triggers, along with a pair of joysticks and at least one thumb-sized touchpad (in addition to the device's touch-sensitive screen). The SteamPal's touchpad is likely smaller than the pair of touchpads that came standard on every Steam Controller. The SteamPal's Switch-like properties will include the option to "dock" to larger monitors via its USB Type-C port, but I don't have firm details on exactly how that connection will work or whether Valve has any plans for an eventual SteamPal dock.

The ability to boot from an external drive on an Apple Silicon Mac may not be an option for much longer, with the creation and use of the drives apparently being phased out by Apple, according to developers of backup tools. Apple Insider reports: Mike Bombich, the founder of Bombich Software behind Carbon Copy Cloner, wrote in a May 19 blog post that the company will continue to make bootable backups for both Intel and Apple Silicon Macs, and will "continue to support that functionality as long as macOS supports it." However, with changes in the way a Mac functions with the introduction of Apple Silicon, the ability to use external booting could be limited, in part due to Apple's design decisions.

The first problem is with macOS Big Sur, as Apple made it so macOS resides on a "cryptographically sealed Signed System Volume," which could only be copied by Apple Software Restore. While CCC has experience with ASR, the tool was deemed to be imperfect, with it failing "with no explanation" and operating in a "very one-dimensional" way. The second snag was Apple Fabric, a storage system that uses per-file encryption keys. However, ASR didn't work for months until the release of macOS 11.3 restored it, but even then kernel panics ensued when cloning back to the original internal storage.

In December, Bombich spoke to Apple about ASR's reliability and was informed that Apple was working to resolve the problem. During the call, Apple's engineers also said that copying macOS system files was "not something that would be supportable in the future." "Many of us in the Mac community could see that this was the direction Apple was moving, and now we finally have confirmation," writes Bombich. "Especially since the introduction of APFS, Apple has been moving towards a lockdown of macOS system files, sacrificing some convenience for increased security." [...] While CCC won't drop the ability to copy the System folder, the tool is "going to continue to offer it with a best effort' approach." Meanwhile, for non-bootable data restoration, CCC's backups do still work with the macOS Migration Assistant, available when booting up a new Mac for the first time.

In late 2019, Qualcomm announced the Snapdragon 8c and 7c, a pair of affordable chips for always-on Windows 10 PCs and Chromebooks. Today, the company is updating the latter of those two SoCs to improve performance. Engadget: The Snapdragon 7c Gen 2 features a Kyro CPU that can achieve clock speeds of up to 2.55GHz. The company claims it delivers 10 percent faster performance than "most competing platforms." Qualcomm likely has processors from Intel's Gemini Lake family in mind here. The company also claims the 7c Gen 2 can deliver up to two times the battery life of its competitors. Outside of the faster CPU, the 7c Gen 2 is more or less the same chip Qualcomm announced in 2019. It features an Adreno 618 GPU and Snapdragon X15 LTE modem. The latter allows the 7c Gen 2 to hit theoretical download speeds of 800 Mbps. As with its predecessor, the chip is designed for education and price-conscious customers. According to Qualcomm, we can expect the first Snapdragon 7c Gen 2 laptops to arrive this summer, with the first models coming from Lenovo.

An anonymous reader quotes a report from CNBC: DarkSide, the hacker group behind the recent Colonial Pipeline ransomware attack, received a total of $90 million in bitcoin ransom payments before shutting down last week, according to new research. Colonial Pipeline was hit with a devastating cyberattack earlier this month that forced the company to shut down approximately 5,500 miles of pipeline in the United States, crippling gas delivery systems in Southeastern states. The FBI blamed the attack on DarkSide, a cybercriminal gang believed to be based in Eastern Europe, and Colonial reportedly paid a $5 million ransom to the group.

On Friday, London-based blockchain analytics firm Elliptic said it had identified the bitcoin wallet used by DarkSide to collect ransom payments from its victims. The same day, security researchers Intel 471 said DarkSide had closed down after losing access to its servers and as its cryptocurrency wallets were emptied. DarkSide also blamed "pressure from the U.S.," according to a note obtained by Intel 471. In a blog post Tuesday, Elliptic said DarkSide and its affiliates bagged at least $90 million in bitcoin ransom payments over the past nine months from 47 victims. The average payment from organizations was likely $1.9 million, Elliptic said. "To our knowledge, this analysis includes all payments made to DarkSide, however further transactions may yet be uncovered, and the figures here should be considered a lower bound," said Tom Robinson Elliptic's co-founder and chief scientist.

According to Elliptic, $15.5 million of the $90 million total haul went to DarkSide's developer while $74.7 million went to its affiliates. The majority of the funds are being sent to crypto exchanges, where they can be converted into fiat money, Elliptic added.

Apple is preparing to release several new Mac laptops and desktops with faster processors, new designs and improved connectivity to external devices, accelerating the company's effort to replace Intel chips and leapfrog rival PC makers. From a report: The overhaul encompasses a broad range of Macs, including Apple's higher-end laptop, the MacBook Pro; the laptop aimed at the mass market, the MacBook Air; and its desktop computers, the Mac Pro, iMac and Mac mini, according to people familiar with the matter. Redesigned MacBook Pros are expected to debut as soon as early this summer, said the people, who requested anonymity to discuss an internal matter, followed by a revamped MacBook Air, a new low-end MacBook Pro and an all-new Mac Pro workstation.

The company is also working on a higher-end Mac mini desktop and larger iMac. The machines will feature processors designed in-house that will greatly outpace the performance and capabilities of the current M1 chips, the people said. Apple plans to launch the redesigned MacBook Pros in 14-inch (code name J314) and 16-inch screen (J316) sizes. They'll have a redesigned chassis, magnetic MagSafe charger and more ports for connecting external drives and devices. Apple is also bringing back the HDMI port and SD card slot, which it nixed in previous versions, sparking criticism from photographers and the like.

Framework is one of an increasing number of companies working to address planned obsolescence by creating products that are incredibly customizable and easy to repair. Today, the company's Framework Laptop is up for preorder, starting at $999 and shipping at the end of July. TechCrunch reports: There are three basic configurations -- Base, Performance and Professional, ranging from $999 to $1,999, upgrading from an Intel Core i5, 8GB of Ram and 256GB of storage to a Core i7 and 32GB/1TB. Windows also gets upgraded from Home to Pro at the top level. At $749, the company offers a barebones shell, where users can plug in their own internals.

Other upgrades include: "On top of that, the Framework Laptop is deeply customizable in unique ways. Our Expansion Card system lets you choose the ports you want and which side you want them on, selecting from four at a time of USB-C, USB-A, HDMI, DisplayPort, MicroSD, ultra-fast 250GB and 1TB storage, and more. Magnetic-attach bezels are color-customizable to match your style, and the keyboard language can be swapped too."

Researchers at Intel Labs have applied machine learning techniques to GTA 5 to make it look incredibly realistic. Gizmodo reports: [I]nstead of training a neural network on famous masterpieces, the researchers at Intel Labs relied on the Cityscapes Dataset, a collection of images of a German city's urban center captured by a car's built-in camera, for training. When a different artistic style is applied to footage using machine learning techniques, the results are often temporally unstable, which means that frame by frame there are weird artifacts jumping around, appearing and reappearing, that diminish how real the results look. With this new approach, the rendered effects exhibit none of those telltale artifacts, because in addition to processing the footage rendered by Grand Theft Auto V's game engine, the neural network also uses other rendered data the game's engine has access to, like the depth of objects in a scene, and information about how the lighting is being processed and rendered.

That's a gross simplification -- you can read a more in-depth explanation of the research here -- but the results are remarkably photorealistic. The surface of the road is smoothed out, highlights on vehicles look more pronounced, and the surrounding hills in several clips look more lush and alive with vegetation. What's even more impressive is that the researchers think, with the right hardware and further optimization, the gameplay footage could be enhanced by their convolutional network at "interactive rates" -- another way to say in real-time -- when baked into a video game's rendering engine.
