Linux 5.11 dominated by descriptors for new AMD silicon

Linus Torvalds has been back at work for a week and already has a second release candidate ready. What’s your excuse?


Linux overlord Linus Torvalds has urged developers to “crawl out from under all the xmas wrapping paper piles and go test” after releasing release candidate two of version 5.11 of the Linux kernel.”

You read that right: Torvalds is already up to rc2, having released rc1 on December 27th, 2020.

On that not-very-busy-for-most-people day Torvalds noted that far and away the biggest piece of new code in version 5.11 was a “huge dump of AMD GPU descriptor header files, which completely dwarfs all the ‘real’ changes here.”

“The AMD ‘Van Gogh’ include file additions are in fact about two thirds of the whole patch, even if it comes from basically one single commit that just adds the register definitions.”

The first point release for Linux 5.10 came out barely a day later because storage bugs broke RAID5* partitions

“Van Gogh” is the codename for future AMD CPUs that will bake in the company’s next-gen “Navi” graphics silicon, kit so powerful AMD hopes it raises the bar for integrated graphics and therefore makes discrete GPUs less attractive. The devices are thought to use the Xen 2 engine and to be aimed at the ultramobile and/or embedded device market. Rumours suggest the devices will emerge mid-2021, while AMD is expected to discuss the details of the products at the virtual CES conference next week.

As Linux 5.11 is at least five weeks from completion, the kernel will be ready to handle the silicon in a timely fashion.

Torvalds is uncertain that this release will be swift. In his missive announcing rc2 he said that while the holiday season “didn't end up affecting things all that much” in terms of new submissions arriving during the merge window, “people have (rightly) mostly been offline since, presumably over-eating and doing all the other traditional holiday things. And just generally not being hugely active.”

The result is a “tiny” rc2 and some Torvaldsian pondering about whether a small rc3 could spell delays, or if version 5.11 will just be a small one because it comes after a long-term-servicing release that naturally gets more attention.

Version 5.11 includes support for Intel’s SGX Enclaves, Guitar Hero controllers and the OUYA Game Console. WiMAX support has been demoted to staging. There’s also the usual round of patches to Xen, support for new Arm SoCs, filesystem fixes, and the addition of support for SD Express cards. ®

  • UK science suffers as lawmakers continue to dither over Brexit negotiations

    Horizons Europe carrot dangled amid protocol wrangling

    A report from the UK House of Commons' European Scrutiny Committee has blamed delays in Brussels for choking off revenue streams to British institutions and businesses.

    The UK departed the European Union following a 2016 referendum. One of the results was that UK businesses were no longer able to tender for lucrative contracts within the bloc.

    The Brexit Divorce Bill uncomfortably laid out the facts back in 2018. The satellite navigation system Galileo was one victim despite substantial involvement from the UK in its development. Another was the Copernicus Earth monitoring programme; the UK was infamously snubbed when the European Space Agency (ESA) handed out six juicy contracts to institutions from the Continent.

  • Everything you wanted to know about modern network congestion control but were perhaps too afraid to ask

    In which a little unfairness can be quite beneficial

    Systems Approach It’s hard not to be amazed by the amount of active research on congestion control over the past 30-plus years. From theory to practice, and with more than its fair share of flame wars, the question of how to manage congestion in the network is a technical challenge that resists an optimal solution while offering countless options for incremental improvement.

    This seems like a good time to take stock of where we are, and ask ourselves what might happen next.

    Congestion control is fundamentally an issue of resource allocation — trying to meet the competing demands that applications have for resources (in a network, these are primarily link bandwidth and router buffers), which ultimately reduces to deciding when to say no and to whom. The best framing of the problem I know traces back to a paper [PDF] by Frank Kelly in 1997, when he characterized congestion control as “a distributed algorithm to share network resources among competing sources, where the goal is to choose source rate so as to maximize aggregate source utility subject to capacity constraints.”

  • How business makes streaming faster and cheaper with CDN and HESP support

    Ensure a high video streaming transmission rate

    Paid Post Here is everything about how the HESP integration helps CDN and the streaming platform by G-Core Labs ensure a high video streaming transmission rate for e-sports and gaming, efficient scalability for e-learning and telemedicine and high quality and minimum latencies for online streams, media and TV broadcasters.

    HESP (High Efficiency Stream Protocol) is a brand new adaptive video streaming protocol. It allows delivery of content with latencies of up to 2 seconds without compromising video quality and broadcasting stability. Unlike comparable solutions, this protocol requires less bandwidth for streaming, which allows businesses to save a lot of money on delivery of content to a large audience.

    Since HESP is based on HTTP, it is suitable for video transmission over CDNs. G-Core Labs was among the world’s first companies to have embedded this protocol in its CDN. With 120 points of presence across 5 continents and over 6,000 peer-to-peer partners, this allows a service provider to deliver videos to millions of viewers, to any devices, anywhere in the world without compromising even 8K video quality. And all this comes at a minimum streaming cost.

  • Cisco deprecates Microsoft management integrations for UCS servers

    Working on Azure integration – but not there yet

    Cisco has deprecated support for some third-party management integrations for its UCS servers, and emerged unable to play nice with Microsoft's most recent offerings.

    Late last week the server contender slipped out an end-of-life notice [PDF] for integrations with Microsoft System Center's Configuration Manager, Operations Manager, and Virtual Machine Manager. Support for plugins to VMware vCenter Orchestrator and vRealize Orchestrator have also been taken out behind an empty rack with a shotgun.

    The Register inquired about the deprecations, and has good news and bad news.

  • Protonmail celebrates Swiss court victory exempting it from telco data retention laws

    Doesn't stop local courts' surveillance orders, though

    Encrypted email provider Protonmail has hailed a recent Swiss legal ruling as a "victory for privacy," after winning a lawsuit that sees it exempted from data retention laws in the mountainous realm.

    Referring to a previous ruling that exempted instant messaging services from data capture and storage laws, the Protonmail team said this week: "Together, these two rulings are a victory for privacy in Switzerland as many Swiss companies are now exempted from handing over certain user information in response to Swiss legal orders."

    Switzerland's Federal Administrative Court ruled on October 22 that email providers in Switzerland are not considered telecommunications providers under Swiss law, thereby removing them from the scope of data retention requirements imposed on telcos.

  • Japan picks AWS and Google for first gov cloud push

    Local players passed over for Digital Agency’s first project

    Japan's Digital Agency has picked Amazon Web Services and Google Cloud for its first big reform push.

    The Agency started operations in September 2021, years after efforts like the UK's Government Digital Service (GDS) or Australia's Digital Transformation Agency (DTA). The body was a signature reform initiated by Prime Minister Yoshihide Suga, who spent his year-long stint in the top job trying to curb Japan's reliance on paper documents, manual processes, and faxes. Japan's many government agencies also operated their websites independently of each other, most with their own design and interface.

    The new Agency therefore has a remit to "cut across all ministries" and "provide services that are driven not toward ministries, agency, laws, or systems, but toward users and to improve user-experience".

  • Singaporean minister touts internet 'kill switch' that finds kids reading net nasties and cuts 'em off ASAP

    Fancies a real-time crowdsourced content rating scheme too

    A Minister in the Singapore government has suggested the creation of an internet kill switch that would prevent minors from reading questionable material online – perhaps using ratings of content created in real time by crowdsourced contributors.

    "The post-COVID world will bring new challenges globally, including to us in the security arena," said Minister for Defence Dr Ng Eng Hen at a Tuesday ceremony to award the city-state's 2021 Defense Technology Prize.

    "For operations, the SAF (Singapore Armed Force) has to expand its capabilities in the digital domain. Whether for administrative or operational purposes, I think that we will need to leverage technology to the maximum," he declared.
