Intel Tries Again To Auto Enable GuC/HuC Functionality For Their Linux Graphics Driver

Filed under
Graphics/Benchmarks

Intel previously tried auto-enabling GuC and HuC functionality within their Linux kernel graphics driver but ended up reverting the support since the driver didn't gracefully handle the scenarios of missing/corrupt firmware files. The driver should now be more robust in such situations so they will try again for turning on the automatic behavior, possibly for the upcoming Linux 5.4 cycle.

Intel GuC and HuC have been around since Skylake and used for graphics workload scheduling, some power management bits, and for select media capabilities. For newer hardware is also being used as part of HEVC/H.265 handling.

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.

  • 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.
