  • Active kernel releases

    Many Linux distributions provide their own "longterm maintenance" kernels that may or may not be based on those maintained by kernel developers. These kernel releases are not hosted at kernel.org and kernel developers can provide no support for them.

    It is easy to tell if you are running a distribution kernel. Unless you downloaded, compiled and installed your own version of kernel from kernel.org, you are running a distribution kernel. To find out the version of your kernel, run uname -r:

  • Linux 5.3 Media Driver Updates Bring New Amlogic Meson Video Decoder

    After going through 9+ rounds of revisions for the Amlogic video decode driver, it's now been part of the media subsystem updates for the Linux 5.3 kernel.

    This Amlogic video decode driver supports the GXBB/GXL/GXM chipsets and allows currently MPEG-1/MPEG-2 decoding with future work to tackle MPEG-4, H.264, HEVC, and VP9.

  • Linux 5.3 Crypto Updates Jitter RNG, Adds xxHash

    Herbert Xu sent out the crypto subsystem updates on Monday for the in-development Linux 5.3 kernel.

    Linux 5.3 is bringing an updated Jitter RNG implementation based on the upstream Jitter 2.1.2 spec with various alterations. There is also now support for the SHA204A random number generator, 5-way interleave support for ECB/CBC/CTR for 64-bit ARM, and other fixes.

  • Raspberry Pi CPUFreq Driver & Other Power Management Work For Linux 5.3

    The power management changes for Linux 5.3 merge window don't offer any P-State changes or other prominent Intel changes this cycle but there is some other improvements as well as new CPUFreq drivers for CPU frequency scaling.

    Arguably the biggest Linux 5.3 power management change is the mainline addition of a CPUFreq driver for Raspberry Pi. This CPUFreq driver communicates with the firmware running on the dedicated processor responsible for clock adjustments. This firmware ends up making the final call on whether to honor requests for CPU clock changes based upon thermal and power criteria.

  • AMD Opens Up Its Contrast Adaptive Sharpening Under FidelityFX On GPUOpen

    Following the Radeon RX 5700 series launch, AMD has now open-sourced their Contrast Adaptive Sharpening (CAS) technology under FidelityFX on GPUOpen. 

    Contrast Adaptive Sharpening provides sharpening and optional scaling and is implemented as HLSL and GLSL shaders for Direct3D and Vulkan. CAS is designed to provide better sharpness with fewer artifacts and to increase the quality of temporal anti-aliasing. 

    The GLSL/Vulkan shaders for CAS are obviously relevant to Linux gamers though this initial FidelityFX release appears catered to a Windows workflow. FidelityFX 1.0 / CAS is licensed under the MIT license. 

  • AMDGPU & RadeonSI Linux Drivers See More Navi Optimizations + Fixes

    t's just not the RADV Vulkan driver seeing lots of Navi activity but the AMDGPU DRM kernel driver and RadeonSI OpenGL Mesa driver are also off to the races in improving their newly-enabled Navi / Radeon RX 5700 series support. 

    On the AMDGPU kernel side, AMD longtime Linux developer Alex Deucher sent out a new PR containing some additional fixes for Navi. This pull request is for the now-open Linux 5.3 merge window to polish up this initial GPU enablement for the kernel. 

    The Navi 10 work that's new for AMDGPU is GPU reset abilities in case of hangs, PowerPlay power management fixes, and graphics fixes. Outside of Navi specific work there is also XGMI fixes, HMM API changes, and other fixes.

DebConf19 invites you to Debian Open Day at the Federal University of Technology - Paraná (UTFPR), in Curitiba

DebConf, the annual conference for Debian contributors and users interested in improving the Debian operating system, will be held in Federal University of Technology - Paraná (UTFPR) in Curitiba, Brazil, from July 21 to 28, 2019. The conference is preceded by DebCamp from July 14 to 19, and the DebConf19 Open Day on July 20. The Open Day, Saturday, 20 July, is targeted at the general public. Events of interest to a wider audience will be offered, ranging from topics specific to Debian to the greater Free Software community and maker movement. The event is a perfect opportunity for interested users to meet the Debian community, for Debian to broaden its community, and for the DebConf sponsors to increase their visibility. Less purely technical than the main conference schedule, the events on Open Day will cover a large range of topics from social and cultural issues to workshops and introductions to Debian. Read more

Sparky Linux 5.8

Today we are looking at Sparky Linux 5.8. This point release of Sparky 5 comes with LXQt 0.14.1, Debian Buster, Linux Kernel 4.19 and uses about 350MB of ram when idling. Sparky Linux LXQt has become one of my favorites, as it has a modern feeling, with the latest of Qt and the stability of Debian, makes it one great combination. Enjoy!

  • What?s next Sparky?

    As before, after releasing a new stable version of Sparky, there are a few changes to do. So… Sparky 4 “Tyche” is moved to oldstable line now. The latest 4.11 release is the last one of the 4 line, but it is still supported, the next 2 years about. Sparky 5 “Nibiru” just released, moving it from testing to stable line. The stable live/install media are available for i686, amd64 & armhf archs (the same as the older release).

Fedora and IBM/Red Hat: Network Security Toolkit (NST), Fedora CoreOS and Openwashing at OSCON

  • Network Security Toolkit (NST) 30 SVN 11210, which is Based on Fedora 30

    Network Security Toolkit (NST) is a Linux-based live operating system that provides a set of free and open-source computer security and networking tools to perform routine security and networking diagnostic and monitoring tasks. It is based on Fedora and NST has included comprehensive set of Open Source Network Security Tools, which is published in sectools.org website. It is offering an advanced Web User Interface (GUI) for system/network administrator, which allows them to configure many network and security applications. NST Team is pleased to announce the latest NST release of “NST 30 SVN:11210” on 1th July 2019.

  • Fedora announces the first preview release of Fedora CoreOS as an automatically updating Linux OS for containerized workloads

    Three days ago, Fedora announced the first preview release of the open-source project Fedora CoreOS as a secure and reliable host for computer clusters. It is specifically designed for running containerized workloads with automatic updates to the latest OS improvements, bug fixes, and security updates. It is secure, minimal, monolithic and is optimized for working with Kubernetes. The main goal of Fedora CoreOS is to be a reliable container host to run containerized workloads securely and at scale. It integrates Ignition from Container Linux technology and rpm-ostree and SELinux hardening from Project Atomic Host. Fedora CoreOS is expected to be a successor to Container Linux eventually. The Container Linux project will continue to be supported throughout 2019, leaving users with ample time to migrate and provide feedback. Fedora has also assured Container Linux users that continued support will be provided to them without any disruption. Fedora CoreOS will also become the successor to Fedora Atomic Host. The current plan is for Fedora Atomic Host to have at least a 29 version and 6 months of lifecycle.

  • IBM helps developers use open source and machine learning

    As artificial intelligence and machine learning become more widespread, it's essential that developers have access to the latest models and data sets. Today at the OSCON 2019 open source developer conference, IBM is announcing the launch of two new projects for developers.
