AMD and Intel: RdRand and Clear Linux Documentation

  • AMD Bulldozer/Jaguar CPUs Will No Longer Advertise RdRand Support Under Linux

    Not directly related to the recent AMD Zen 2 BIOS update needed to fix an RdRand problem (though somewhat related in that the original systemd bug report for faulty AMD RdRand stems from these earlier CPUs), but AMD has now decided to no longer advertise RdRand support for Family 15h (Bulldozer) and Family 16h (Jaguar) processors under Linux.

    The RdRand instruction will still work on capable CPUs, but the CPU ID bit is being cleared so that it won't be advertised for software explicitly checking for the support. Tom Lendacky of AMD reesorted to clearing the RDRAND CPU ID bit for 15h/16h processors (no impact for Zen, etc) due to RdRand issues cropping up after suspend/resume. Those issues have affected some users for a while and originate with the original AMD RdRand systemd bug report over problems following that cycle.

  • Clear Linux Project has a new documentation site

    The Clear Linux OS Docs team is happy to announce that our documentation site for the Clear Linux Project has moved to a Sphinx/reST site with the ubiquitous Read-The-Docs theme, consistent with many open source documentation projects.

  • Clear Linux Rolls Out Revamped Documentation

    While Arch Linux remains the gold standard for quality Linux documentation, Intel's Clear Linux has rolled out a new documentation web-site to assist new/existing users in making use of this performance-optimized and security-oriented Linux operating system.

Clear Linux launches a new documentation website

  • Clear Linux launches a new documentation website

    Clear Linux fans will now be able to have better access to more information about the operating system as Clear Linux announces a new and improved documentation website.

    New Linux users can be somewhat unfamiliar with the Clear Linux Project. Accordingly, let FOSSLinux give a brief introduction of this wonderful operating system. Powered by Intel, the Clear Linux OS is a Linux-based, rolling-release distro that has its eyes set on providing optimal performance and security. Other than that, users will also find this operating system to be manageable and customizable.

    Now that we’re done with its introduction let’s get to the actual news. The new Clear Linux documentation site is based on a Sphinx/reST framework and uses the Read-The-Docs theme, which you will find on most of the documentation sites out there. With this, it can be seen that Clear Linux wants to stay in the same lane as its competition.

Debian: CUPS, LTS and Archival

  • Praise Be CUPS Driverless Printing

    Last Tuesday, I finally got to start updating $work's many desktop computers to Debian Buster. I use Puppet to manage them remotely, so major upgrades basically mean reinstalling machines from scratch and running Puppet. Over the years, the main upgrade hurdle has always been making our very large and very complicated printers work on Debian. Unsurprisingly, the blog posts I have written on that topic are very popular and get me a few 'thank you' emails per month. I'm very happy to say, thanks to CUPS Driverless Printing (CUPS 2.2.2+), all those trials and tribulations are finally over. Printing on Buster just works. Yes yes, even color booklets printed on 11x17 paper folded in 3 stapled in the middle.

  • Freexian’s report about Debian Long Term Support, August 2019

    Like each month, here comes a report about the work of paid contributors to Debian LTS.

  • Louis-Philippe Véronneau: Archiving 20 years of online content

    mailman2 is pretty great. You can get a dump of an email list pretty easily and mailman3's web frontend, the lovely hyperkitty, is well, lovely. Importing a legacy mailman2 mbox went without a hitch thanks to the awesome hyperkitty_import importer. Kudos to the Debian Mailman Team for packaging this in Debian for us. But what about cramming a Yahoo! Group mailing list in hyperkitty? I wouldn't recommend it. After way too many hours spent battling character encoding errors I just decided people that wanted to read obscure emails from 2003 would have to deal with broken accents and shit. But hey, it kinda works! Oh, and yes, archiving a Yahoo! Group with an old borken Perl script wasn't an easy task. Hell, I kept getting blacklisted by Yahoo! for scraping too much data to their liking. I ended up patching together the results of multiple runs over a few weeks to get the full mbox and attachments. By the way, if anyone knows how to tell hyperkitty to stop at a certain year (i.e. not display links for 2019 when the list stopped in 2006), please ping me.

Running The AMD "ABBA" Ryzen 3000 Boost Fix Under Linux With 140 Tests

Last week AMD's AGESA "ABBA" update began shipping with a fix to how the boost clock frequencies are handled in hopes of better achieving the rated boost frequencies for Ryzen 3000 series processors. I've been running some tests of an updated ASUS BIOS with this adjusted boost clock behavior to see how it performs under Linux with a Ryzen 9 3900X processor. The AGESA 1.0.0.3 ABBA update has an improved boost clock frequency algorithm along with changes to the idle state handling. This AGESA update should better position AMD Ryzen 3000 processors with the boost clock behavior expected by users with better hitting the maximum boost frequency and doing so more aggressively.

Linux Container Technology Explained (Contributed)

State and local governments’ IT departments increasingly rely on DevOps practices and agile development methodologies to improve service delivery and to help maintain a culture of constant collaboration, iteration, and flexibility among all stakeholders and teams. However, when an IT department adopts agile and DevOps practices and methodologies, traditional IT problems still need to be solved. One long-standing problem is “environmental drift,” when the code and configurations for applications and their underlying infrastructure can vary between different environments. State and local IT teams often lack the tools necessary to mitigate the effects of environmental drift, which can hamper collaboration and agility efforts. Read more
