Marvell lifts curtain on popular NAS SoCs

Filed under
Linux
Hardware

[Updated 12:00PM] — Marvell has posted detailed datasheets on its previously opaque Armada 370 and XP SoCs, used in Linux-based NAS systems from Buffalo, Netgear, and Synology.

Until now, datasheets and other details about the ARM-based Armada 370 and Armada XP system-on-chips have been available only under NDA to Marvell customers and partners. During the past month, however, the chipmaker released detailed datasheets on the SoCs, with no restriction or registration required. Both functional and hardware spec datasheets were released, each of which is more like a manual than a typical datasheet.

We were tipped to the Marvell Armada 370 and XP datasheet releases by embedded Linux development and training specialist Free Electrons. (The company is well known here for its regular contributions of videos and slide decks from shows like the Embedded Linux Conference, released under a Creative Commons license.)

Linux will not become a gaming platform, it already is one

Filed under
Linux
Gaming

The true measure of any great gaming platform is not the number of games available. Nor is it the need to have the same games as other competing platforms (the Playstation 4 doesn't need Mario games to be considered successful). And it really isn't even about how many total games are sold, though that certainly helps.

Time was, if you had a hankering for a nice Raspberry Pi, you had but one choice: the Raspberry Pi Model B. You plunked down your $35, and like millions of other Pi-heads, you liked it. Then came the stripped-down $25 Model A, followed this year by the Raspberry Pi Compute Module. Now they've got this gussied up Raspberry Pi Model B+ with four USB ports and a backward-compatible 40-pin expansion connector. What's the world coming to?

MySQL 5.6.20 Officially Released

Filed under
Server
Software

As usual, any new version of MySQL brings lots of improvements, and the current build is also quite large. Users will find that numerous changes have been made and some of them are quite interesting.

“The linked OpenSSL library for the MySQL 5.6 Commercial Server has been updated from version 1.0.1g to version 1.0.1h. Versions of OpenSSL prior to and including 1.0.1g are reported to be vulnerable to CVE-2014-0224. This change does not affect the Oracle-produced MySQL Community build of MySQL Server 5.6, which uses the yaSSL library instead,” notes the changelog.

SUSE and Red Hat Leftovers

  • Skuba on SUSE CaaS Platform 4

    With SUSE CaaS Platform 4 we heard our customers feedback and decided to change what the lifecycle of the platform looks like. Previous versions of SUSE CaaS Platform included an administrator node that despite being useful for managing the whole platform, was another component to take care of, and an extra machine to take into account when deploying the platform. This administrator node used Salt to set up and maintain the Kubernetes cluster among the different nodes comprising your cluster. During this time, your feedback has been that a little more flexibility on the deployment was appreciated, so you could experiment with slightly different setups, even if they were for proof of concepts while you were fleshing out the details of production clusters.

  • Kubernetes Rolling Update Strategy in our production infra

    Kubernetes rolling update strategy means suppose we are running pod (containers) in our live infra and we want to update new changes into our running pod like build update, confrontational changes etc. While deployment new pod with new changes suppose our containers got stuck or failed due to any reason. So, we have to redeploy old pod with old changes again to avoid downtime of our application. This complete process is called rolling update strategy in Kubernetes. Kubernetes rolling update strategy Before moving to next we should aware about new pod deployment strategy of Kubernetes means how many new pods it will deploy at a time without taking downtime. Because high availability of our website is our first priority. So, while deploying new pod Kubernetes will deploy 25% or you can say one fourth of the total pod. Suppose we are running four pods first it will terminate 25% of total pod means one pod. Then it will launch 25% new pod and so on.

  • Tackle OpenStack networking woes with SUSE OpenStack Cloud Crowbar

    By far, the most difficult aspect of successfully deploying OpenStack is getting the networking right, a challenge that has caused many a well-intentioned IT team to throw up its hands and toss in the towel. Fortunately, SUSE OpenStack Cloud removes much of that pain by automating most of the network deployment and dramatically simplifying custom network set-ups.

  • How to Handle OpenShift Worker Nodes Resources in Overcommitted State

    One of the benefits in adopting a system like OpenShift is facilitating burstable and scalable workload. Horizontal application scaling involves adding or removing instances of an application to match demand. When OpenShift schedules a Pod, it’s important that the nodes have enough resources to actually run it. If a user schedules a large application (in the form of Pod) on a node with limited resources , it is possible for the node to run out of memory or CPU resources and for things to stop working! It’s also possible for applications to take up more resources than they should. This could be caused by a team spinning up more replicas than they need to artificially decrease latency or simply because of a configuration change that causes a program to go out of control and try to use 100% of the available CPU resources. Regardless of whether the issue is caused by a bad developer, bad code, or bad luck, what’s important is how a cluster administrator can manage and maintain control of the resources. In this blog, let’s take a look at how you can solve these problems using best practices.

  • How the new Quarkus extension for Visual Studio Code improves the development experience

    Earlier this year, we were introduced to Quarkus, the next-generation, container-first framework for Java applications. As expected, such new frameworks and technologies make way for new developer tools focused on making the development experience even better. The recent Quarkus extension for Visual Studio Code release aims to do just that, by bringing features specific to Quarkus project development within VS Code. The new VS Code extension is dependent on a couple of Java extensions for VS Code, so it is recommended that you have the Java Extension Pack installed. This article outlines what the Quarkus extension for VS Code has to offer: convenient features for an already convenient Java framework.

Security: New Updates and "Optimizing KVM Virtualization Performance Stemming From Spectre"

  • Security updates for Monday

    Security updates have been issued by Debian (expat, php-pecl-http, and php7.0), Fedora (ImageMagick, jackson-annotations, jackson-bom, jackson-core, jackson-databind, and rubygem-rmagick), Mageia (chromium-browser-stable, ibus, kernel, samba, and thunderbird), openSUSE (chromium), Oracle (dovecot and kernel), Red Hat (dbus, kernel, kernel-alt, and kpatch-patch), Scientific Linux (dovecot and kernel), and SUSE (expat, ibus, kernel, kernel-source-rt, nmap, openssl, and webkit2gtk3).

  • Red Hat Working On Optimizing KVM Virtualization Performance Stemming From Spectre

    Red Hat's Andrea Arcangeli sent out an interesting patch series on Friday to micro-optimize the Kernel-based Virtual Machine (KVM) to enhance the VMEXIT performance in wake of Spectre mitigations. The "KVM monolithic" patch series ends up linking the KVM common code both into kvm-intel and kvm-amd so that the common "kvm" kernel module can be dropped. This occupies more disk space but should yield better run-time performance particularly for systems mitigated against Spectre Variant Two.

Kernel: AMD Navi 10 Firmware and Linux 5.4 Additions

  • AMD Navi 10 Firmware Finally Lands In The Linux-Firmware Tree

    While AMD has provided open-source Radeon RX 5700 series (Navi 10) support since launch and that code since worked into the various mainline code-bases from the Linux kernel to Mesa, one kink in their support has been their binary microcode images not being available from the reference linux-firmware.git location as needed to initialize the hardware. That Navi 10 firmware/microcode issue has finally been rectified with the images landing this morning. Up until now any Radeon RX 5700 series Linux customers or distribution/third-party driver packagers have had to pull these binary bits from this Navi10 directory on the personal site of AMDGPU lead maintainer Alex Deucher. Via his site is where he normally stages these binary microcode files until landing in linux-firmware.git as the de facto location for all Linux drivers' firmware files.

  • Linux 5.4 Brings Support For Wacom's MobileStudio Pro 13, Logitech Lightspeed Receivers

  • Wireless USB + UWB Demotion Goes Ahead For Linux 5.4

    Back in August I noted that Wireless USB and Ultra Wideband would be deprecated within the Linux kernel and that is indeed happening for Linux 5.4. The Wireless USB (WUSB) and Ultra Wideband (UWB) subsystems within the Linux kernel were already orphaned for years with having no maintainer while now they are officially deprecated and demoted to the kernel's staging area. If no one steps up soon to maintain the code, it will be dropped in forthcoming kernel releases.
