  • Mesa 19.3 Has The Very Preliminary OpenGL + Vulkan Driver Support Ready For Intel Gen12

    Similar to the flurry of Radeon driver activity in buttoning things up ahead of the Mesa 19.3 feature freeze, the Intel open-source crew has landed some last-minute bits around the Tiger Lake "Gen 12" enablement.

    In recent months there has been a lot of Intel Tiger Lake / Gen12 Linux enablement activity. On the kernel side Linux 5.4 has the initial bits to be evolved over the coming cycles. Meanwhile over in user-space the initial "Iris" OpenGL and "ANV" Vulkan driver support is in place for Mesa 19.3.

  • Mesa 19.3-RC1 Released With OpenGL 4.6 For Intel, Many Vulkan Driver Improvements

    Mesa 19.3 feature development is now officially over and Mesa 20.0 is open for development on Git master. This final Mesa series of 2019 comes with many exciting OpenGL and Vulkan drivers.

    One of the key improvements with Mesa 19.3 is that Intel's OpenGL i965/Iris drivers now supports OpenGL 4.6! Thanks to the SPIR-V ingestion support finally landing, the Intel open-source Linux graphics driver finally has OpenGL 4.6 capabilities in full. AMD has also been working towards RadeonSI OpenGL 4.6 support but with that also transitioning them to NIR it's been a long-time coming and hasn't materialized for Mesa's final 2019 release.

  • mesa 19.3.0-rc1
    Hi List,
    
    I'd like to announce the availability of 19.3.0-rc1 and the beginning of the
    19.3.0 release cycle. Despite the short release cycle we've got plenty of good
    things in store for you. Among them the OpenGL 4.6, initial Intel gen12 support,
    lots of new Vulkan extensions, and meson support for windows.
    
    Expect a new RC each Wednesday for the next few weeks until the release tracker
    is cleared. You can see the tracker here:
    https://gitlab.freedesktop.org/mesa/mesa/-/milestones/5. Please be sure to add
    any issues to that tracker that block the release.

  • Radeon Open-Source Linux Graphics Have A Wild Day For Mesa 19.3 From 8K Decode To ACO

    With Mesa 19.3 scheduled to be branched today and that marking the end of feature development for this next quarterly installment to these open-source Linux OpenGL/Vulkan drivers, developers are in a mad rush landing last minute improvements. The open-source Radeon driver support has a lot to stand in particular from today's work.

Native Linux & Raspberry Pi support for checkra1n jailbreak hinted by developer

Despite hitting the market first, iPhone comes behind Android in terms of popularity. We admit the price plays a significant role here. But, a Samsung or Huawei flagship user who can afford an iPhone will tell you the level of customisation or convenience is what brought them to Android. Let’s set the convenience part aside because it is not really an issue after we get accustomed to the whole ecosystem of a device. However when it comes to the customisation, we can’t deny Android from bagging the pole position. Read more

Linux Kernel Security in a Nutshell: How to Secure Your Linux System

The Linux kernel is the core component of the Linux operating system, maintaining complete control over everything in the system. It is the interface between applications and data processing at the hardware level, connecting the system hardware to the application software. The kernel manages input/output requests from software, memory, processes, peripherals and security, among other hefty responsibilities. Needless to say, the Linux kernel is pretty important. However, with power comes great responsibility, and the Linux kernel is no exception to this rule. Kernel security is critical: it determines the security of the Linux operating system as a whole, as well as the security of every individual system that runs on Linux. Vulnerabilities in the kernel can have serious implications for Linux users, and it is extremely important that users stay up-to-date on news and advisories pertaining to kernel security. Read more

Mozilla: Webcompat, Firefox 71, Privacy Advice and Rust

  • Karl Dubost: Saving Webcompat images as a microservice

    Thinking out loud on separating our images into a separate service. The initial goal was to push the images to the cloud, but I think we could probably have a first step. We could keep the images on our server, but instead of the current save, we could send them to another service, let say upload.webcompat.com with a HTTP PUT. And this service would save them locally.

  • Multiple-column Layout and column-span in Firefox 71

    Firefox 71 is an exciting release for anyone who cares about CSS Layout. While I am very excited to have subgrid available in Firefox, there is another property that I’ve been keeping an eye on. Firefox 71 implements column-span from Multiple-column Layout. In this post I’ll explain what it is and a little about the progress of the Multiple-column Layout specification. Multiple-column Layout, usually referred to as multicol, is a layout method that does something quite different to layout methods such as flexbox and grid. If you have some content marked up and displaying in Normal Flow, and turn that into a multicol container using the column-width or column-count properties, it will display as a set of columns. Unlike Flexbox or Grid however, the content inside the columns flows just as it did in Normal Flow. The difference is that it now flows into a number of anonymous column boxes, much like content in a newspaper.

  • The Mozilla Blog: Can Your Holiday Gift Spy on You?

    Mozilla today launches the third-annual *Privacy Not Included, a report and shopping guide identifying which connected gadgets and toys are secure and trustworthy — and which aren’t. The goal is two-fold: arm shoppers with the information they need to choose gifts that protect the privacy of their friends and family. And, spur the tech industry to do more to safeguard consumers. Mozilla researchers reviewed 76 popular connected gifts available for purchase in the United States across six categories: Toys & Games; Smart Home; Entertainment; Wearables; Health & Exercise; and Pets. Researchers combed through privacy policies, sifted through product and app specifications, reached out to companies about their encryption and bug bounty programs, and more. As a result, we can answer questions like: How accessible is the privacy policy, if there is one? Does the product require strong passwords? Does it collect biometric data? And, Are there automatic security updates?
