Linux Won't Boot on New MacBook Air: Apple's T2 Security Chip Prevents It

The new MacBook Air with Retina display is overall a nice upgrade from the old versions of these laptops. There's one caveat, though: the new T2 chip that manages Touch ID's Secure Enclave, APFS storage encryption or UEFI Secure Boot validation will make it impossible to boot with a Linux distribution. Apple's T2 documentation (PDF) explicitly covers how the support for booting Linux is not available: the Microsoft Corporation UEFI CA 2011 certificate used also by Linux distributions isn't trusted at this moment, so the T2 chip will make it impossible to boot from Linux distributions. Only Windows is allowed to boot via Boot Camp at the moment.

Apple's Secure Boot support page shows how the new 'Startup Security Utility' can be used to disable Secure Boot, but some people have tried to boot Linux through this method and even with that change it's impossible to boot Linux. The problem extends to the rest of machines including the T2 Security Chip, like the Mac mini, the iMac Pro or the MacBook Pro 2018, for example. Apple hasn't made any comments on the issue.

AMD Zen 2 GNU Compiler Patch Published, Exposes New Instruction Sets

With a November deadline for feature freeze fast approaching, GNU toolchain developers are now adding the last feature additions to GCC 9.0 (GNU Compiler Collection). Ahead of that deadline, AMD has released their first basic patch adding the "znver2" target and therefore Zen 2 support to GCC. While the patch uses the same cost tables and scheduler data as Znver1, it does feature three new instructions that will be available to AMD's next-gen CPUs which include; Cache Line Write Back (CLWB), Read Processor ID (RDPID), and Write Back and Do Not Invalidate Cache (WBNOINVD).

These three instructions are the only ones that have been found thus far by digging through the current code. Taking into account this is the first patch it can be considered a jumping off point, making sure that the GCC 9.1 stable update, which comes out in 2019, has support for Zen 2. Further optimizations and instructions may be implemented in the future. This is likely since AMD has yet to update the scheduler cost tables and by extension means they may not want to reveal everything about Zen 2 just yet. You could say AMD is for now playing it safe, at least until their 7nm EPYC 2 processors launch in 2019.

Two Months After Proton Over 2,500 Windows Games Work On Linux Through Steam Play

Proton is a new tool released by Valve Software that has been integrated with Steam Play to make playing Windows games on Linux as simple as hitting the Play button within Steam. Underneath the hood, Proton comprises other popular tools like Wine and DXVK among others that a gamer would otherwise have to install and maintain themselves. This greatly eases the burden for users to switch to Linux without having to learn the underlying systems or losing access to a large part of their library of games. Proton is still in its infancy so support is inconsistent, but regularly improving and the list of supported Windows games is growing each day.

In fact, this project has announced that it has now over 2,500 Windows games (2,663 at the time of writing) that work on Linux with Proton and Steam Play. Beyond those supported "whitelisted" games, there are several others that although not-whitelisted are supported and "play just as well as on Windows". Some examples are "No Man's Sky", "The Witcher 3: Wild Hunt", "Wolfenstein: The New Order" or "The Elder Scrolls V: Skyrim". Any user can contribute and report about the titles in his game library thanks to ProtonDB.

AMD Vega 20 Possible Performance Spotted in Final Fantasy XV Benchmark

It would appear AMD's 7nm Vega 20 has been benchmarked in Final Fantasy XV. While the details are scarce, what we do know is the hardware device ID 66AF:C1 can be linked to Vega 20 via the Linux patches back in April. Now considering AMD has not confirmed any 7nm Vega graphics cards for consumers, It is more likely this version is an engineering sample for the new Radeon Instinct or Pro series cards.

Microsoft Joins the Open Invention Network, Adds 60,000 Patents To Protect Linux and Open Source

Steve Ballmer once said 'Linux is a cancer'. Times have changed a lot, and since Satya Nadella became CEO of Microsoft, Linux and Open Source have become really important for Redmond's company. Azure is based on Linux, for example, and this OS dominates the cloud platform with about half of Azure VMs being Linux ones). Running Linux distributions such as Ubuntu, SuSE or Fedora is also possible natively under Windows 10 through Windows Subsystem for Linux.

The company has made big strategic acquisitions, and Microsoft recently acquired Github, but that approach to Linux and Open Source goes further with the new announcement. Microsoft has joined the Open Invention Network (OIN), a consortium that defines itself as a "shared defensive patent pool with the mission to protect Linux". With that move, Microsoft is bringing 60,000 patents to OIN that will be available royalty-free to anyone who joins the OIN community.

Linux Community Hit by the Blight of Social Justice Warfare, A Great Purge is Coming

Through the 1990s, Microsoft had become a super-corporation threatening to monopolize all of computing. A band of talented developers got together with lawyers that could fish out loopholes in proprietary licenses, and with some generosity from big software, Linux grew from a scrappy Unix-like OS kernel to the preeminent operating system for enterprises at first, and handheld consumer electronics later. Today it's most popular operating system on the planet. Like every big organization, the Linux Foundation is hit by employee-activism.

Employee-activism is the new unionism. Whereas trade-unions of the old fought for tangible bread-and-butter issues affecting blue-collar folk of the early Industrial era, today's employee-activist is an intellectual predator seeking to maximize their organizational footprint on the backs of other people echoing their political ideas, often through blatant insubordination and disregard for the chain of command. Survival of the fittest has changed to "survival of the loudest." From forcing Linus Torvalds to apologize for speaking his mind in public, to coming up with a new Code of Conduct document, social-justice activism within the Linux Foundation threatens to devolve the culture of meritocracy to a toxic "safe space" prioritizing inclusion of identity rather than skill, as HardOCP comments. A major blow-back from the meritocrats is taking shape.

AMD Implements xGMI for "Vega 20" as Competition to NVLink

xGMI (inter-chip global memory interconnect) is a cable-capable version of AMD's Infinity Fabric interconnect. A line of code in the latest version of AMDGPU Linux drivers reveals that "Vega 20" will support xGMI. This line tells the driver to check the state of xGMI link. A practical implementation of this could be inter-card high-bandwidth bridge connectivity that would otherwise saturate the PCI-Express host bus; similar to NVIDIA's usage of the new NVLink bridge for Quadro and Tesla products based on its "Volta" and "Turing" GPU architectures.

By no means should xGMI and NVLink implementations be interpreted as a coming back of multi-GPU to the gaming space. There are still no takers for DirectX 12 multi-GPU, and fewer AAA games support SLI or CrossFire. Even at higher resolutions/refresh-rates, existing SLI/CrossFire physical-layer standards have sufficient bandwidth for multi-GPU. The upcoming GeForce RTX 2000 graphics cards feature a new multi-GPU connector that's physically NVLink, but this is probably an attempt by NVIDIA to discard the legacy SLI bus and minimize redundant interfaces on its silicon. The TU102 and TU104 chips are implemented in the enterprise segment with the Quadro RTX family. The main application of xGMI/NVLink is to make multi-GPU hardware setups abstract to deep-learning software, so hardware can scale in the background with memory access spanning multiple GPUs. "Vega 20" will be launched in Radeon Pro and Radeon Instinct avatars late-2018.

Valve Apparently Working on Compatibility Tools Allowing Windows Games to be Played on Linux

Keen-eyed Linux and Valve uses have noticed what could seemingly be a big reveal and shake-up to games' compatibility with the Linux platform. If you're a die-hard Linux fan, or even if you're just a curious dabbler in that operating system, you know that there aren't many concerted efforts of bringing game experiences to that operating system. A good port requires many more hours than game developers are willing to put into it - let alone compiling a native implementation of their game for that OS.

However, Valve, being the most important digital games distributor through their Steam platform, know there's an untapped source of income in that part of the market. And if developers won't do it themselves, then Valve seem to be willing to take the matter into their own hands. This speculation arises from Steam's GUI files, which when looked at with SteamDB's Steam Tracker, include a hidden section with unused text related to an (as of yet) unannounced Steam Play system, which "(...) will automatically install compatibility tools that allow you to play games from your library that were built for other operating systems."

Swedish Firm EQT Acquires SuSE from Microsoft-funded Previous Owners

Swedish company EQT, which invests heavily in tech stocks, and even owns tech IP, closed a deal with Micro Focus to acquire SuSE, lock stock and barrel. Over the past 15 years, SuSE changed many owners. In 2004, the Nuremberg-based Linux distributor was acquired by Novell. In 2010, Novell was swallowed by Attachmate, with funding from Microsoft. In 2014, ten years since its original foreign acquisition, Micro Focus acquired Attachmate and spun off SuSE as a separate division within the company. EQT purchased this division from Micro Focus in a deal valued at USD $2.5 billion.

Recognizable by its quirky chameleon mascot, SuSE's biggest product is SuSE Linux, a commercial distribution of Linux for enterprises, which integrates certain proprietary software and drivers, with a business-model similar to that of RHEL (Red Hat Enterprise Linux). There's also a GNU-friendly, community-maintained free distribution of SuSE called OpenSuSE, which is made entirely of free and open-source software. The acquisition of SuSE is big, not just because of its valuation, but also because certain EU-based businesses and governments use it in their vital IT infrastructure. The EQT acquisition keeps SuSE within the EU.

Google Might Be Preparing a Kaby Lake G-Powered Chromebook

Chromebooks are all the rage right now. As a matter of fact, Acer recently released the first convertible Chromebook and a couple of other premium models aimed at business users. Google isn't staying behind either. A device under the codename "Kidd" was recently discovered in a Chromium OS code commit. Kidd is allegedly supposed to be a Chromebook, and the first to come with a quad-core Kaby Lake G processor with AMD Radeon Vega graphics inside. The Kaby Lake G family is comprised of the Intel Core i5-8305G, i7-8705G, i7-8706G, i7-8709G, and i7-8809G. That's a total of five processors for Google to choose from. But, at the moment, it's unclear whether Kidd will employ a 65 watt model or opt for a more powerful 100 watt variant.

The latest Chrome OS update brought support for Linux applications. Therefore, users can now install Steam on their Chromebooks. While GPU acceleration isn't quite there yet, it's on the roadmap. Support for GPU acceleration should arrive later this year. Once that happens, users will finally be able to game on the Chrome OS. So, expect to see a lot more Chromebooks with Raven Ridge and Kaby Lake G processors very soon.

Canonical Launches Ubuntu 18.04 LTS

Ubuntu 18.04 LTS - the newest version of the most widely used Linux for workstations, cloud and IoT, is now available. "Multi-cloud operations are the new normal" said Mark Shuttleworth, CEO of Canonical and founder of Ubuntu. "Boot-time and performance-optimized images of Ubuntu 18.04 LTS on every major public cloud make it the fastest and most efficient OS for cloud computing, especially for storage and compute-intensive tasks like machine learning."

Kubeflow, the Google approach to TensorFlow on Kubernetes, and a range of CI/CD tools are integrated in Canonical Kubernetes and aligned with Google GKE for on-premise and on-cloud AI development."Having an OS that is tuned for advanced workloads such as AI and ML is critical to a high velocity team" said David Aronchick, Product Manager, Cloud AI at Google. "With the release of Ubuntu 18.04 LTS and Canonical's collaborations to the Kubeflow project, Canonical has provided both a familiar and highly performant operating system that works everywhere. Whether on-premise or in the cloud, software engineers and data scientists can use tools they are already familiar with, such as Ubuntu, Kubernetes and Kubeflow, and greatly accelerate their ability to deliver value for their customers."

Feral Interactive Introduces GameMode Tool for Linux Gamers to Optimize Gaming Performance

Feral Interactive has released their free, open-source tool called GameMode to help Linux gamers squeeze every drop of gaming performance out of their systems. GameMode is basically a small daemon and library combo that instructs the processor to run in Performance Mode when a user is playing a game. GameMode along with the instructions for installation can be found at GitHub. Feral Interactive also took the opportunity to announce that Rise of the Tomb Raider, which lands on Linux later this month, will be the first Linux title to integrate GameMode. Future titles from the video game publisher will probably include GameMode as well.

Compulab Intros Mintbox Mini 2 PC based on Linux Mint

Compulab rolled out the Mintbox Mini 2, a smaller version of the Mintbox 2 the company rolled out way back in 2013. The Mintbox Mini 2 is based almost entirely on the Compulab Fitlet 2 mini-PC, but with Linux Mint with all device drivers pre-installed, and some exclusive branding. This box is based on the slightly older Intel Celeron J3455 SoC with embedded Intel HD Graphics 500 (and not the latest Celeron J4005). It's still claimed to be close to twice as fast as the AMD A4-6400T-based original. Besides the SoC, the storage specs appear to be identical - 4 GB RAM, 64 GB storage, but there are improvements on some fronts - dual-band 802.11ac + Bluetooth 4.2 WLAN (as opposed to 802.11 b/g/n on the original), and two wired GbE interfaces instead of just one. The Mintbox Mini 2 is priced at USD $299, just $4 more than the original Mintbox Mini, but a staggering $146 higher than the Fitlet 2. This is not because of the OS, but pre-installed RAM, storage, and WLAN module.

Rise of the Tomb Raider: 20 Year Celebration Comes to macOS & Linux This Spring

Intel's Patch for Meltdown, Spectre "Complete and Utter Garbage:" Linus Torvalds

Linus Torvalds, creator of Linux, the most popular datacenter operating system, proclaimed Intel's patches for the recent Meltdown and Spectre CPU vulnerabilities "complete and utter garbage." Torvalds continues to work on the innermost code of Linux, and has been closely associated with kernel patches that are supposed to work in conjunction with updated CPU microcode to mitigate the two vulnerabilities that threaten to severely compromise security of data-centers and cloud-computing service providers.

Torvalds, in a heated public chain-mail with David Woodhouse, an Amazon engineer based out of the UK, called Intel's fix "insane" and questioned its intent behind making the patch "toggle-able" (any admin can disable the patch to a seemingly cataclysmic vulnerability, which can bring down a Fortune 500 company). Torvalds also takes issue with redundant fixes to vulnerabilities already patched by Google Project Zero "retpoline" technique. Later down in the thread, Woodhouse admits that there's no good reason for Intel's patches to be an "opt-in." Intel commented on this exchange with a vanilla-flavored potato: "We take the feedback of industry partners seriously. We are actively engaging with the Linux community, including Linus, as we seek to work together on solutions."

Intel Secretly Firefighting a Major CPU Bug Affecting Datacenters?

There are ominous signs that Intel may be secretly fixing a major security vulnerability affecting its processors, which threatens to severely damage its brand equity among datacenter and cloud-computing customers. The vulnerability lets users of a virtual machine (VM) access data of another VM on the same physical machine (a memory leak). Amazon, Google, and Microsoft are among the big three cloud providers affected by this vulnerability, and Intel is reportedly in embargoed communications with engineers from the three, to release a software patch that fixes the bug. Trouble is, the patch inflicts an unavoidable performance penalty ranging between 30-35%, impacting the economics of using Intel processors versus AMD ones.

Signs of Intel secretly fixing the bug surfaced with rapid changes to the Linux kernel without proper public-visibility of the documentation. The bulk of the changes involve "kernel page table isolation," a feature that prevents VMs from reading each other's data, but at performance costs. Developers note that these changes are being introduced "very fast" by Linux kernel update standards, and even being backported to older kernel versions (something that's extremely rare). Since this is a hardware vulnerability, Linux isn't the only vulnerable software platform. Microsoft has been working on a Windows kernel patch for this issue since November 2017. AMD x86 processors (such as Opteron, Ryzen, EPYC, etc.,) are immune to this vulnerability.

Zorloo Announces Their Second-Generation Portable USB-DAC

Zorloo is pleased to introduce its second-generation portable USB-DAC product, ZuperDAC-S, today. It builds on its wildly praised ZuperDAC to enable computers or mobile phones an unprecedented HiFi music experience. Today, computers and mobile phones are powerful enough to handle different audio protocols. However, the last but most critical step in the entire digital-to-analog conversion process, i.e. turning musical data 0 and 1 into audible sound waves, always sucks. Constrained by the limitation of this internal conversion process, audio may also have to be re-sampled to fit the pipeline.

Bypassing the internal conversion with ZuperDAC-S drastically improves sound quality to a new level. It supports up to 192kHz sampling frequency and 24-bit depth, which eliminates unnecessary sample rate and bit depth conversion. The music output from ZuperDAC-S is exactly what was recorded. ZuperDAC-S uses the ESS Sabre 9018 audiodac and delivers a stunning 120dB SNR and 0.0005% THD+N performance. It delivers a balanced, clear and articulated sound in a wide soundstage. The integrated headphone amplifier output can connect directly to headphones, or go through the amplifier systems.

AMD Releases AMDVLK - Open-Source Vulkan Driver for Linux

AMD released the AMDVLK drivers for Linux. These are the first open-source AMD Radeon graphics drivers featuring 100% support for Vulkan 1.0 graphics API. The drivers include Vulkan 1.0 compliance with support for 30 Vulkan extensions, Radeon GPU Profiler support, in-built debug and profiling tools, mid-command buffer preemption, and SR-IOV virtualization support. AMDVLK implements AMD's Platform Abstraction Library (PAL), an abstraction layer that translates much of AMD's common driver code and features across platforms. The drivers support all AMD Radeon GPUs based on the Graphics CoreNext architecture, going all the way back to the Radeon HD 7000-series. The drivers are released through AMD's GPUOpen GitHub repository.

NVIDIA to End Support for 32-bit Operating Systems After R390 Drivers

NVIDIA announced that it is ending driver support for 32-bit operating systems after its R390-series drivers. Following its GeForce 390.xx release, NVIDIA will not support 32-bit versions of Windows 10, Windows 7, Windows 8/8.1, Linux, or FreeBSD for any of its GPU architectures. NVIDIA will, however, offer support for critical driver security fixes for 32-bit operating systems until January 2019. This means the company will release hotfixes addressing specific critical security vulnerabilities in the drivers, as and when they're found, but such hotfixes won't include new features or optimizations that are part of the main driver trunk for 64-bit operating systems.
