  • AI-Powered / Machine Learning Linux Performance Tuning Is Now A Thing

    A year and a half ago I wrote about a start-up working on dynamically-tuned, self-optimizing Linux servers. That company is now known as Concertio and they just launched their "AI powered" toolkit for IT administrators and performance engineers to optimize their server performance.

    Concertio Optimizer Studio is their product making use of machine learning that aims to optimize Linux systems with Intel CPUs for peak performance by scoping out the impact of hundreds of different tunables for trying to deliver an optimal configuration package for that workload on that hardware.

  • Pengutronix Gets Open-Source 3D Working On MX8M/GC7000 Hardware

    We've known that Pengutronix developers had been working on i.MX8M / GC7000 graphics support within their Etnaviv open-source driver stack from initial patches posted in January. Those patches back at the start of the year were for the DRM kernel driver, but it turns out they have already got basic 3D acceleration working.

  • SDL Now Disables Mir By Default In Favor Of Wayland Compatibility

    With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move.

  • Mesa 18.1 Receives OpenGL 3.1 With ARB_compatibility For Gallium3D Drivers

    Going back to last October, Marek of AMD's open-source driver team has been working on ARB_compatibility support for Mesa with a focus on RadeonSI/Gallium3D. Today that work was finally merged.

    The ARB_compatibility support allows use of deprecated/removed features of OpenGL by newer versions of the specification. ARB_compatibility is particularly useful for OpenGL workstation users where there are many applications notorious for relying upon compatibility contexts / deprecated GL functionality. But ARB_compatibility is also used by a handful of Linux games too.

  • AMDGPU In Linux 4.17 Exposes WattMan Features, GPU Voltage/Power Via Hwmon

    AMD's Alex Deucher today sent in the first pull request to DRM-Next of AMDGPU (and Radeon) DRM driver feature material that will in turn be merged with the Linux 4.17 kernel down the road. There's some fun features for AMDGPU users coming with this next kernel!

    First up, Linux is finally getting some WattMan-like functionality after it's been available via the Windows Radeon Software driver since 2016. WattMan allows for more fine-tuning of GPU clocks, voltages, and more for trying to maximize the power efficiency. See the aforelinked article for details but currently without any GUI panel for tweaking all of the driver tunables, this WattMan-like support needs to be toggled from the command-line.

  • February 2018 coreboot update now available

    Hey everyone, I’m happy to announce the release of an update to our coreboot images for Librem 13 v2 and Librem 15 v3 machines.

    All new laptops will come pre-loaded with this new update, and everyone else can update their machines using our existing build script which was updated to build the newest image. Some important remarks:

  • Purism Releases Updated Coreboot Images For Their Laptops

    Purism has released updated Coreboot images for their Librem 13 v2 and Librem 15 v3 laptops.

    The updated Coreboot images are now re-based to Coreboot 4.7, Intel FSP 2.0, IOMMU (VT-d) support is now available, TPM support is also enabled, and there are fixed ATA errors for 6Gbps speeds.

  • New Inventory with TPM by Default, Free International Shipping

    In November, we announced the availability of our Trusted Platform Module as a $99 add-on for early adopters, something that would allow us to cover the additional parts & labor costs, as well as test the waters to see how much demand there might be for this feature. We thought there would be “some” interest in that as an option, but we were not sure how much, especially since it was clearly presented as an “early preview” and offered at extra cost.

Canonical Releases Major Kernel Security Update for Ubuntu 14.04 to Fix 26 Flaws

Filed under
Linux

A total of 26 security flaws were fixed in today's kernel update for Ubuntu 14.04 LTS systems and derivatives, including an out-of-bounds write vulnerability in Linux kernel's F2F (Flash-Friendly File System) file system, a use-after-free flaw in Linux kernel's ALSA PCM subsystem, and an integer overflow in Linux kernel's sysfs interface for the QLogic 24xx+ series SCSI driver.

Additionally, the kernel update addresses a use-after-free vulnerability in Linux kernel's SCTP protocol implementation, as well as a race condition in the LEGO USB Infrared Tower driver and a use-after-free vulnerability in the USB serial console driver, both allowing a physically proximate attacker to execute arbitrary code or crash the system with a denial of service attack.

Plasma Mobile Could Give Life to a Mobile Linux Experience

Linux

In the past few years, it’s become clear that, outside of powering Android, Linux on mobile devices has been a resounding failure. Canonical came close, even releasing devices running Ubuntu Touch. Unfortunately, the idea of Scopes was doomed before it touched down on its first piece of hardware and subsequently died a silent death.

The next best hope for mobile Linux comes in the form of the Samsung DeX program. With DeX, users will be able to install an app (Linux On Galaxy—not available yet) on their Samsung devices, which would in turn allow them to run a full-blown Linux distribution. The caveat here is that you’ll be running both Android and Linux at the same time—which is not exactly an efficient use of resources. On top of that, most Linux distributions aren’t designed to run on such small form factors. The good news for DeX is that, when you run Linux on Galaxy and dock your Samsung device to DeX, that Linux OS will be running on your connected monitor—so form factor issues need not apply.

Overview Of tcpdump With Examples

Filed under
Linux

You can view information about traffic coming and going from a given network interface using tcpdump. This diagnostic tool allows you to see packet information, that is where incoming packets come from and where outgoing packets are heading to on an interface, with some extra information. You can even save the output to a file to inspect later on. This article will demonstrate the simple examples of tcpdump.

  • Linux Adds CH341 GPIO

    There was a time when USB to serial hardware meant one company: FTDI. But today there are quite a few to choose from and one of the most common ones is the WCH CH341. There’s been support for these chips in Linux for a while, but only for use as a communication port. The device actually has RS232, I2C, SPI, and 8 general purpose I/O (GPIO) pins. [ZooBaB] took an out-of-tree driver that exposes the GPIO, and got it working with some frightening-looking CH341 boards.

  • Shrinking the kernel with an axe

    This is the third article of a series discussing various methods of reducing the size of the Linux kernel to make it suitable for small environments. The first article provided a short rationale for this topic, and covered link-time garbage collection. The second article covered link-time optimization (LTO) and compared its results to link-time garbage collection. In this article we'll explore ways to make LTO more effective at optimizing kernel code away, as well as more assertive strategies to achieve our goal.

  • The rest of the 4.16 merge window

    At the close of the 4.16 merge window, 11,746 non-merge changesets had been merged; that is 5,000 since last week's summary. This merge window is thus a busy one, though not out of line with its predecessors — 4.14 had 11,500 changesets during its merge window, while 4.15 had 12,599. Quite a bit of that work is of the boring internal variety; over 600 of those changesets were device-tree updates, for example. But there was still a fair amount of interesting work merged in the second half of the 4.16 merge window; read on for the highlights.

  • Linux Kernel Module Growth

    The Linux kernel grows at an amazing pace, each kernel release adds more functionality, more drivers and hence more kernel modules. I recently wondered what the trend was for kernel module growth per release, so I performed module builds on kernels v2.6.24 through to v4.16-rc2 for x86-64 to get a better idea of growth rates...

  • A Linux Kernel Driver Is Being Worked On For Valve's Steam Controller

    Right now to make most use of the Steam Controller on Linux you need to be using the Steam client while there have been independent user-space programs like SC-Controller to enable Steam Controller functionality without the Steam client running. A new and independent effort is a Linux kernel driver for the Steam Controller.

    Through reverse-engineering, Rodrigo Rivas Costa has been developing a kernel driver for the Valve Steam Controller. This driver supports both USB cable and USB wireless adapters for the Steam Controller. This driver is being developed as a proper HID kernel driver so it should work with all existing Linux programs and doesn't require the use of the proprietary Steam client.

FATHOM releases Crystallon

  • FATHOM releases Crystallon, an open-source software for lattice-based design
    Lattice structures are integral to 3D printed designs, and Aaron Porterfield, an industrial designer at additive manufacturing service bureau FATHOM, has developed Crystallon, an open source project for shaping them into structures.
  • FATHOM Introduces Open Source Software Project for Generating 3D Lattice Structures
    California-based FATHOM, which expanded its on-site managed services and announced important partnerships with Stratasys and Desktop Metal last year, is introducing a fascinating new open source project called Crystallon, which uses Rhino and Grasshopper3D to create lattice structures. FATHOM industrial designer Aaron Porterfield, also an Instructables member, developed the project as an alternative to designing lattices with commercially available software. He joined the company’s design and engineering team three years ago, and is often a featured speaker for its Design for Additive Manufacturing (DfAM) Training Program – and as the project developer, who better to explain the Crystallon project?
