  • Linux 5.3 Picks Up Utilization Clamping - Ensuring GUI Threads Get Maximum Frequency

    The scheduler changes for the Linux 5.3 kernel are as busy as ever.

    One of the most interesting scheduler changes for Linux 5.3 was made by Arm's Patrick Bellasi. The addition is introducing utilization clamping support as an extension of their work on the Energy Aware Scheduling framework in order to boost some workloads while capping background workloads. Energy Aware Scheduling factors in the CPU topology of modern hardware -- particularly Arm big.LITTLE designs -- with differing power and performance characteristics in order to better schedule what CPU cores should be used for a given workload.

  • Linux 5.3 Continues Advancing Intel's Sound Open Firmware

    Linux sound subsystem maintainer Takashi Iwai sent in the big set of audio driver changes for Linux 5.3.

    Linux 5.3 is continuing where Linux 5.2 left off when it added a lot of their Sound Open Firmware kernel code that has been in development for over one year as the Intel-led effort for having open-source audio DSP firmware and SDK. Sound Open Firmware is used by the newest and future Google Chromebooks among other use-cases to come about.

  • The Linux Foundation Breathes New Life into Osquery

    Anyone who has been tasked with monitoring the security of server instances in a data center or cloud knows how laborious and time-consuming it can be. Osquery, a project started by Facebook, aims to lessen this burden by reframing how developers engage with their infrastructures. DevOps professionals can use Osquery to expose an operating system as a high-performance relational database, making it possible to use SQL commands to access data about a system, just as they would for a database. 

    Osquery works on Mac, Linux and Windows systems and is provided as an open source download via GitHub. Although Osquery was developed by Facebook to monitor and safeguard the security of its own platform, the social media giant quickly realized the utility of the platform would extend to other enterprises that depend upon insight into the low-level behavior of operating systems. 

Linux's Perf Subsystem Begins Prepping For Snow Ridge

  • Linux's Perf Subsystem Begins Prepping For Snow Ridge, Other New Intel Hardware Support

    Snow Ridge is the SoC Intel announced last December as a 10nm product intended for 5G products. With the in-development Linux 5.3 kernel is initial "perf" subsystem support for Snow Ridge.

    The perf subsystem support for the Snow Ridge bring-up has uncore support so far. There is also a number of PMU/uncore driver updates for Intel's Icelake, Kabylake, Amberlake, and Whiskeylake processors.

Graphics: AMD, GNOME Shell on Wayland and NVIDIA Nsight Graphics

  • AMD Pushes Back 3rd Gen Threadripper & Ryzen 9 3950X Until November

    While the Ryzen 9 3950X and 3rd Gen Ryzen Threadripper processors were reportedly on track for launching in October with updates as of a few weeks ago, today AMD announced a slight delay in launching these new processors.

  • AMD have delayed the Ryzen 9 3950X and 3rd generation Threadripper until November

    Today, AMD sent out a brief statement about a delay in their 16 core Ryzen 9 3950X and the 3rd generation Threadripper. [...] So if you were looking to grab either, keep an eye out in November. Will share any more news when they send it about the expected date and pricing.

  • AMD Sends In Initial Batch Of Fixes To Linux 5.4 - Includes Dali Support

    While just yesterday the big DRM feature pull was sent in for Linux 5.4, AMD has also volleyed out their initial batch of fixes for this next version of the kernel. This new AMDGPU pull isn't strictly fixes but as anticipated does include the recently reported Dali APU support. Dali along with Renoir -- also newly-supported in Linux 5.4 -- are some of AMD's 2020 APUs. Dali will be targeting the lower-end of the spectrum it's expected for value mobile/embedded. From the driver code, Dali looks like a newer revved version of the current-gen Picasso APUs. Both Dali and Renoir are based on the Vega architecture.

  • Linux Plumbers Conference 2019, part 2

    Pain points and missing pieces with Wayland, or specifically GNOME Shell: GNOME Shell is slower Synergy doesn't work(?) - needs to be in the compositor With Nvidia proprietary driver, mutter and native Wayland clients get GPU acceleration but X clients don't No equivalent to ssh -X. Pipewire goes some way to the solution. The whole desktop can be remoted over RDP which can be tunnelled over SSH. No remote login protocol like XDMCP No Xvfb equivalent Various X utilities that grab hot-keys don't have equivalents for Wayland Not sure if all X's video acceleration features are implemented. Colour format conversion and hardware scaling are implemented. Pointer movement becomes sluggish after a while (maybe related to GC in GNOME Shell?) Performance, in general. GNOME Shell currently has to work as both a Wayland server and an X compositor, which limits the ability to optimise for Wayland.

  • NVIDIA's Nsight Graphics 2019.5 Released With Better Vulkan Coverage

Ubuntu: Video Encoder Performance, Ubuntu Touch, LZ4 Compression

  • Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K

    Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux. On the same Core i9 9900K system I recently ran some benchmarks looking at Clear Linux vs. Ubuntu 19.10 and then Ubuntu 19.10 with various common tunables to make it more akin to Clear Linux. Ubuntu 19.10 was used due to its recent software components being at similar versions to Intel's rolling-release distribution.

  • Serge Hallyn: First experience with Ubuntu Touch

    For the past few weeks I’ve been using a nexus 4 running ubuntu touch as, mostly, my daily driver. I’ve enjoyed it quite a bit. In part that’s just the awesome size of the nexus 4. In part, it’s the ubuntu touch interface itself. If you haven’t tried it, you really should. (Sailfish ambiances are so much prettier, but ubuntu touch is much nicer to use – the quick switch to switch between two apps, for instance. Would that I could have both.). And in part it’s just the fact that it really feels like – is – a regular ubuntu system.

  • Ubuntu 19.10 to use LZ4 compression to boot even faster

    anonical’s Ubuntu 19.10 “Eoan Ermine” will boot even faster than its predecessor, Ubuntu 19.04 “Disco Dingo” according to Ubuntu’s kernel team. After extensive testing on a variety of compression options on the Ubuntu installation image, Canonical engineers determined that the LZ4 decompression method provided a most appreciable gain in speed.

  • New Version Vivaldi Web Browser Has Been Released, Install in Ubuntu/Linux

    Vivaldi is the new web browser compare to other famous browsers, the initial release of Vivaldi was in January, 2015. It has improved a lot and evolved since the first release. Basically it is based on the open-source frameworks of Chromium, Blink and Google's V8 JavaScript engine and has a lot of great feature which I will table later. It is known to be the most customizable browser for power users, debuts features that make browsing more personal than ever before. Do we really need another browser? Since we already have a lot of them such as mostly used Firefox, Chrome, Opera and so on. The former CEO of Opera Software Jon Von Tetzchner didn't liked the direction of Opera Web Browser and said "Sadly, it is no longer serving its community of users and contributors - who helped build the browser in the first place." Then created a web browser which has to be fast, rich feature, highly flexible and puts the user first, so Vivaldi was born.
