    Half of the reason to buy a Mac is to get native support for macOS, but that doesn’t mean Mac owners don’t also suffer from the grass-is-greener syndrome. While Apple’s operating system is known for being casual friendly and is also the OS system people who grew up on its products might be more familiar with, PC users are always quick to point out that the extra steps it adds to actions like installing programs can slow down more serious work. It’s currently possible to emulate Windows for ARM on Apple’s latest M1 Macs, but what if you want to take your power user cred a step further and use Linux on your new M1 Mac?

  • 2021 Could Be The Year That AMD Radeon Graphics Can Hot Unplug Gracefully On Linux - Phoronix

    It's been nearly one year that AMDGPU patches have been around to better handle GPU hot unplugging on Linux. The use-case for that being either removal via sysfs such as if then assigning the GPU to a VM or for external GPUs such as connected via Thunderbolt. Those patches are still baking but the latest iteration of the work has now been published by AMD.

    Currently the hot removal of AMD Radeon GPUs under Linux can result in a kernel oops or system hangs or application hangs, among related headaches. Reportedly, Windows doesn't handle the GPU hot-unplug situation much better.

  • Ubuntu Now Runs on Apple Silicon, Devs Say It’s ‘Completely Usable’

    Developers at ARM virtualisation company Corellium have managed to get Ubuntu 20.04 up and running on the new Apple Silicon Mac Mini.

    And we’re not talking ‘it boots and prints a load of text’ running here. No, this is the full Ubuntu desktop experience — and it’s already being described as “completely usable”!

  • Linux is now 'fully usable' on Apple Silicon M1 Macs

    Security researchers at Corellium have ported a version of Linux to the Apple Silicon M1 chip that will ultimately be released under an open-source license.

    The Linux version is a full Ubuntu desktop operating system booted from a USB, according to Corellium Chief Technology Officer Chris Wade. Although details are scarce, he said that Linux is now "completely usable" on Apple Silicon machines.

Initial Patches Posted For Bringing Up The Linux Kernel On Apple

  • Initial Patches Posted For Bringing Up The Linux Kernel On Apple Silicon M1 Hardware

    Following a very active past couple of days, developers from security startup Corellium have followed through on their word so far of publishing the Apple Silicon patches to the Linux kernel mailing list for possible upstreaming in the future that allow the Linux kernel to boot with Apple M1 hardware.

    Corellium developers sent out their first set of seven patches under a "request for comments" flag this morning. These are the minimal changes needed for getting Linux to boot on the current Apple M1 ARM-based hardware.

Linux on the Apple M1 takes another step closer with Ubuntu work

  • Linux on the Apple M1 takes another step closer with Ubuntu working thanks to Corellium

    ARM virtualization company Corellium has managed to get Ubuntu Linux running on the next-generation Apple M1.

    The news comes from Corellium CEO, Chris Wade, who mentioned on Twitter how "Linux is now completely usable on the Mac mini M1. Booting from USB a full Ubuntu desktop (rpi). Network works via a USB c dongle. Update includes support for USB, I2C, DART. We will push changes to our GitHub and a tutorial later today.".

    Impressive speedy work, and a separate project to the recently revealed Asahi Linux which is also aiming to do the same thing. Two heads are better than one, as they say. The Corellium team mentioned on Twitter they full back the Asahi project too, so it's wonderful to see true cooperation.

    Right now this effort doesn't appear to have full GPU acceleration so it's doing software rendering, making it less suitable for a daily driver but work is ongoing towards that. Eventually everything will be in place, and it's taking far less time than I personally expected to see it running on such brand new hardware from Apple.

Linux is Finally on Apple M1...Kind Of.

  • Linux now 'completely usable' on M1 Mac mini

    The initial announcement came with a warning that the "very early" beta was for "advanced users only", and that USB support and a more complete release was on the way.

    As Wade has now noted, users can now boot from USB to a full Ubuntu desktop.

  • Apple M1 Macs can now run Ubuntu Linux thanks to Corellium

    The sheer impressive power of the Apple Silicon M1 processor has made developers, hackers, and tinkerers daydream about possible use cases beyond what Apple intended or would even allow. Some have already gotten Windows to run on it, in a virtualized environment fashion, of course. Now a few security researchers have also figured out how to run Linux directly on the hardware, albeit with a few catches that could still make it not that useful for a daily driver for Linux users.

  • ‘Completely Usable’ M1 Mac Version of Ubuntu Linux Now Available

    ARM software virtualization company Corellium has released a “completely usable” version of Ubuntu Linux that runs on M1 Macs. Corellium CTO Chris Wade announced the release early this morning.

    Security researchers at the company have developed a port that has been released on GitHub with an installation tutorial is said to be coming later today.

  • Ubuntu has been ported to Mac M1 devices

    Many Mac users utilize a dual-boot setup with their devices. However, that hasn’t been possible for the Mac M1, at least until now. A (very) barebones version of Ubuntu can now dual-boot on M1-powered Macs, though most will want to hold off on installing it for now.

  • M1 Macs can now run full version of Linux thanks to new Corellium port

    Since the new M1 Macs were announced, developers have been working to run different operating systems on the Apple Silicon platform, including Windows and Linux. Now, thanks to Corellium, it’s possible to run Ubuntu — a popular Linux distro — on new Macs with M1 chip.

    The announcement was made on Twitter by Corellium’s CTO Chris Wade. Corellium offers solutions for virtualization of ARM devices and platforms, and it was recently involved in a lawsuit with Apple regarding a tool that lets users virtualize iOS.

  • You can now run Linux on Apple M1 devices

    Developers from security startup Corellium have revealed they managed to get Linux running on Apple's Arm-based M1 devices natively.

    While Linux, and even Windows, were already usable on Apple Silicon thanks to virtualization, this is the first instance of a non-macOS operating system running natively on the hardware.

    “Linux is now completely usable on the Mac mini M1. Booting from USB a full Ubuntu desktop (rpi),” wrote Corellium’s CTO Chris Wade on Twitter while sharing pictures of Ubuntu's Raspberry Pi ARMv8 desktop image booting on Apple M1 hardware.

Linux has been ported to run on Apple’s M1 Macs

  • Linux has been ported to run on Apple’s M1 Macs

    A new Linux port allows Apple’s M1 Macs to run Ubuntu for the first time. Corellium, a security firm that offers a virtualized version of iOS for security testing, has successfully ported Ubuntu over to M1 Macs and released a tutorial for others to follow. The modified version of Ubuntu boots into the regular user interface and includes USB support.

    The team at Corellium have detailed exactly how they managed to get Ubuntu running, and it’s a good in-depth read if you’re interested in the details. While a number of M1 components are shared with Apple’s mobile chips, the non-standard chips made it challenging to create Linux drivers to get Ubuntu running properly.

Corellium ports Linux to Apple M1 Mac mini

  • Corellium ports Linux to Apple M1 Mac mini

    I was sure that Linux would eventually run on Apple's ARM-based M1 CPU. After all, Linux has been ported to essentially every processor on the planet. Even without Apple's co-operation, it would only be a matter of time. I'd assumed it would take a year or so. I was wrong. Correllium, a company specializing in ARM virtualization and developer tools, has successfully ported Linux to Apple's new M1-powered Mac mini.

    [...]

    For now, only people who really know Linux should be trying this out. Wade said that binary files and a how-to document are being worked on. For the moment, you must still compile the linux-M1 code yourself.

    That done, you can boot your M1 Mac mini from a USB stick into a full Ubuntu Linux desktop. For networking, you'll also need a USB-C dongle. More work is being done, even as I write this, to include better USB and I2C serial communications protocol.

    Behind the scenes, the M1 Linux port is based on work done in Corelliums' Project Sandcastle. This was a project to get Android and Linux running on iPhones.

    In short, although the M1 is a new chip, with its work on iPhone chipsets Corellium was already digging the foundations for Linux on M1. That's because "many of the devices on the SoC [System on a Chip] didn't change from the programmers' perspective."

How We Ported Linux to the M1

  • How We Ported Linux to the M1

    When Apple released their desktop products with the M1 processor in November 2020, quite a few people in the tech community were surprised by the excellent performance of these systems. But those who have been following the development of Apple phone chipsets closely knew that the evolutionary path Apple followed would result in a powerful 64-bit ARM processor.

    At Corellium, we've been tracking the Apple mobile ecosystem since iPhone 6, released in 2014 with two 64-bit cores. Since then, Apple has been focusing their energy on building faster chips, preferring to improve single-threaded performance over throwing more cores on the chip. This approach was enabled by their in-house hardware design team, and resulted in unique parts with a broad feature set, leading the industry in terms of architectural features.

    It also made Apple silicon rather distinct from all other 64-bit ARM hardware in terms of both CPU core and peripherals. Our Corellium virtualization platform has been providing security researchers with unparalleled insight into how operating systems and programs work on Apple ARM processors. But in the process of developing our virtualization system, we also gain knowledge about the hardware we are modeling, and this knowledge can be best refined by testing it against real hardware - which we have only been able to do with the emergence of checkm8, an exploit that let us load programs onto Apple smartphones. This led directly to the Sandcastle project, where we built a kernel port to the A10 processor in early 2020.

Finally! Linux Runs Gracefully On Apple M1 Chip

  • Finally! Linux Runs Gracefully On Apple M1 Chip

    Apple’s M1 chip is continuously in the buzz because of its impressive capability of monstrous performance on their own ARM-based MacBook and Mac Mini.

    And, for that reason, many Linux users want to get their hands on them. But without proper Linux support, it would be a nightmare.

    While Linus Torvalds didn’t have high hopes for this to happen, it looks like Corellium – a company who specializes with ARM device virtualization has finally made it possible.

    In a tweet by Chris Wade (CTO of Corellium), he mentions that Linux is completely usable on a Mac Mini M1. Before you blindly grab a device with Apple Silicon, let me tell you more about it.

Ubuntu Linux is now running on M1 Macs

We turn away for a second and Corellium is already showing off

  • We turn away for a second and Corellium is already showing off Ubuntu on Apple Silicon

    Those with pockets deep enough to spring for Apple's latest and greatest and a desire to avoid macOS can follow a relatively straightforward guide from Corellium on getting the Raspberry Pi image of Ubuntu 20.10 up and running. "We used a Raspberry Pi image because it was a live USB boot image, so we only had to make minor modifications to boot it," the team explained.

    Corellium also paid tribute to the team behind PongoOS – a pre-boot execution environment for Apple boards – "for contributing their expertise and collaboration".

    An RFC has been submitted to upstream with a view to review and potentially include the changes for a minimal Linux on Apple Silicon boot. The latest patches were pushed to the GitHub repo late yesterday.

    There are alternatives in the works too. The Asahi Linux project notwithstanding, virtualization is also an option.

    Corellium has announced it has Ubuntu Linux running on an M1 Mac, in what is described as a “completely usable” experience.

    Mac computers are popular options for Linux users and developers. Many want to combine their operating system (OS) of choice with machines that are widely considered to be among the best industrial designs in the business.

    With Apple moving to its own custom silicon, however, there was doubt about the future of Linux on Macs. Apple’s new M1 chip is an ARM-based designed, similar to what the company has been running in iPhones and iPads for years.

    Even Linus Torvalds has said he would love to run one of the new M1 Macs, but wasn’t optimistic it could run Linux.

    The chips are based on ARM architecture, same as the iPhone, iPad, and Apple TV processors. The change means that the new M1 Macs will not support the use of Bootcamp which is used to install Windows alongside macOS or even flavours of Linux. However, to rescue, a security firm named Corellium has successfully ported Ubuntu to M1 Macs.

    Not a fan of Apple’s macOS operating system but like the new M1 hardware that accompanies it? Then maybe installing a different operating system could be the answer, and no, we’re not talking about Windows. Thanks to the team at Corellium, it appears that they have managed to get Linux up and running on the M1 powered Mac mini.

    According to Corellium’s Chief Technology Office Chris Wade, this is a full version of the Ubuntu desktop operating system that has been booted from a USB drive. While Wade does not dive into the details, he does claim that the version of Linux they installed is “completely usable” on Apple Silicon computers.

  • You can run Linux on an M1 Mac if you have the patience | Engadget

    Corellium has successfully run Ubuntu Linux on Apple's M1 Macs, although you'll need a USB drive and some know-how to make it work.

  • Someone ported Linux to the new Arm-based Mac Mini

    Running Linux on Intel-based Macs is relatively easy. Now that Apple is transitioning to its own silicon, it is no longer so straightforward. Although the M1 SoCs are Arm-based processors, and there are Arm versions of Linux available, components on the new Apple chips don't play well with current Linux distos.

    Apple has not made dual-booting easy on its newest Arm-based computers. While there are Linux distros designed to run on Arm hardware, Apple silicon is a different breed. However, Security researchers at Corellium have a working Linux port for Apple's M1 Macs.

    The operating system Corellium developed is an Arm-based Ubuntu distro that boots from a USB drive, but it is not as simple as plug-and-play. The main hurdle to getting Linux running on the M1 is hardware drivers.

In AppleInsider

  • How Linux was ported to the Apple Silicon M1 Mac mini

    Linux now works on the Mac mini with M1 processor — but Apple did not make it easy for the team to port the OS with its custom firmware and unique data paths. Here's how Corellium got it done.

    Now that Linux is fully usable on Macs with M1 processors the team at Corellium has detailed their process for porting the OS.

    In Thursday's post, Corellium says that they have been studying Apple's custom processors since the iPhone 6 released in 2014. The company used some exploits and the previous study to build a kernel port to the A10 processor in early 2020.

    Apple released the Macs with M1 processor in November 2020. A follow-on OS update enabled users to install custom kernels. Following the addition of that ability, the Corellium team began working on a Linux port.

Ubuntu Linux Now Runs On Apple M1 Silicon Macs

  • Ubuntu Linux Now Runs On Apple M1 Silicon Macs, What To Expect And How To Prepare

    One of the more pragmatic aspects of Intel-powered Macs was their ability to run alternative operating systems, including Windows and Linux, without much effort at all. Apple even included a Windows preparation tool, Boot Camp, on all of its systems with Intel Core processors. With the advent of Apple Silicon Macs (such as the recent Mac mini) that have the company's M1 SoC under the hood, Apple discontinued Boot Camp. Those systems had been locked into macOS 11 Big Sur, but thanks to Arm-based virtual cloud device maker Corellium, Ubuntu Linux is now "completely usable."

    Arm offers an array of licenses to its architecture that range from processor licenses, in which a chip vendor can whole hog plug modules of Arm CPU cores into a chip, to the more abstracted architecture license, which is what Apple uses to develop custom Arm64 CPUs for its own devices. Being an architecture licensee, Apple is beholden to nobody in the way that its chips implement the ISA and boot an operating system. According to Corellium, those implementation differences are what made it a bit more difficult to get running Ubuntu. In a series of tweets, Corellium's Chief Technical Officer Chris Wade recently showed off Ubuntu running on an Apple M1-powered Mac mini, so we felt compelled to explore it a little ourselves as well.

Lilbits: Linux on Apple Silicon...

  • Lilbits: Linux on Apple Silicon and the uncertain future of the LG Rollable smartphone

    Apple launched the first Macs with Apple Silicon a few months ago, delivering a big boost in performance while also reducing power consumption. One downside of Apple’s switch from Intel processors to its own ARM-based custom chips though, is that you can no longer easily install Windows alongside macOS using Boot Camp, and for a while there was no easy way to install GNU/Linux distributions either.

    But this week developers at ARM virtualization company Corellium announced that they’d ported Linux to run on a Mac Mini with an Apple M1 chip. Corellium CTO Chris Wade says the team’s proof of concept build of Ubuntu (based on a version made to run on Raspberry Pi computers) is “completely usable,” and boots a “full Ubuntu desktop” from a USB flash drive.

    The vintage at play here is Ubuntu, and the port was created by Corellium, which in any case virtualizes iOS and other ARM-based OSes to empower simpler security testing. It’s important also that Apple has recently sued the organization over said iOS security testing tool. The lawsuit didn’t turn out well for Apple.

    Corellium Chief Technology Office Chris Wade declared the culmination of the cooperation on Twitter yesterday.

4 new open source licenses

As the steward of the Open Source Defintion, the Open Source Initiative has been designating licenses as "open source" for over 20 years. These licenses are the foundation of the open source software ecosystem, ensuring that everyone can use, improve, and share software. When a license is approved, it is because the OSI believes that the license fosters collaboration and sharing for the benefit of everyone who participates in the ecosystem. The world has changed over the past 20 years, with software now used in new and even unimaginable ways. The OSI has seen that the familiar open source licenses are not always well-suited for these new situations. But license stewards have stepped up, submitting several new licenses for more expansive uses. The OSI was challenged to evaluate whether these new concepts in licensing would continue to advance sharing and collaboration and merit being referred to as "open source" licenses, ultimately approving some new special purpose licenses.

Can Linux Run Video Games?

Linux is a widely used and popular open source operating system that was first released back in 1991. It differs from operating systems like Windows and macOS in that it is open source and it is highly customizable through its use of “distributions”. Distributions or “distros” are basically different versions of Linux that can be installed along with the Linux core software so that users can customize their system to fit their specific need. Some of the more popular Linux distributions are Ubuntu, Debian and Fedora. For many years Linux had the reputation of being a terrible gaming platform and it was believed that users wouldn’t be able to engage in this popular form of entertainment. The main reason for this is that commercially successful games just weren’t being developed for Linux. A few well known video game titles like Doom, Quake and SimCity made it to Linux but for the most part they were overlooked through the 1990’s. However, things have changed a lot since then and there is an every expanding library of popular video games you can play on Linux. [...] There are plenty of Windows games you can run on Linux and no reason why you can’t play as well as you do when using Windows. If you are having trouble leveling up or winning the best loot, consider trying AskBoosters for help with your game. Aside from native Linux games and Windows games there are a huge amount of browser based games that work on any system including Linux. Read more

  • Update CentOS Linux for free

    As you may know, in December 2020 IBM/Red Hat announced that CentOS Linux 8 will end in December 2021. Additionally, the updates for CentOS Linux 6 ended on November 30, 2020. If your organization relies on CentOS, you are faced with finding an alternative OS. The lack of regular updates puts these systems at increasing risk for major vulnerabilities with every passing day. A popular solution with minimal disruption is to simply point your CentOS systems to receive updates from Oracle Linux. This can be done anonymously and at no charge to your organization. With Oracle Linux, you can continue to benefit from a similar, stable CentOS alternative. Oracle Linux updates and errata are freely available and can be applied to CentOS or Red Hat Enterprise Linux (RHEL) instances without reinstalling the operating system. Just connect to the Oracle Linux yum server, and follow these instructions. Best of all, your apps continue to run as usual.

  • Malware in open-source web extensions

    Since the original creator has exclusive control over the account for the distribution channel (which is typically the user's only gateway to the program), it logically follows that they are responsible for transferring control to future maintainers, despite the fact that they may only have the copyright on a portion of the software. Additionally, as the distribution-channel account is the property of the project owner, they can sell that account and the accompanying maintainership. After all, while the code of the extension might be owned by its larger community, the distributing account certainly isn't. Such is what occurred for The Great Suspender, which was a Chrome extension on the Web Store that suspends inactive tabs, halting their scripts and releasing most of the resources from memory. In June 2020, Dean Oemcke, the creator and longtime maintainer, decided to move on from the project. He transferred the GitHub repository and the Web Store rights, announcing the change in a GitHub issue that said nothing about the identity of the new maintainer. The announcement even made a concerning mention of a purchase, which raises the question of who would pay money for a free extension, and why. Of course, as the vast majority of the users of The Great Suspender were not interested in its open-source nature, few of them noticed until October, when the new maintainer made a perfectly ordinary release on the Chrome Web Store. Well, perfectly ordinary except for the minor details that the release did not match the contents of the Git repository, was not tagged on GitHub, and lacked a changelog.
