  • The source of law here is Directive 2022/2380 (which amends Directive 2014/53), in Article 2 a grace period until 2026-04-28 is defined for the category of laptops. This has now expired, which explains the renewed wave of articles being published.

    The directive itself is not that interesting to read, as a lot of it is just empowering the Commission to make a decision on the specifics. The result is in the Commission Delegated Regulation 2023/1717. Although it seems to me like something is missing. I can’t find more though.

    A very interesting Q&A from their Commission Notice – Guidance document:

    1. Are laptops and other radio equipment that require more than 240 W of charging power exempted from the ‘common charger’ rules?

    No. They are not exempted. Radio equipment which is subject to the ‘common charger’ rules must incorporate the harmonised charging solution.

    The Commission has updated (in Commission Delegated Regulation (EU) 2023/1717), the references to the standards cited in Annex Ia to the latest version of the European standards. Therefore, due to the amendments introduced by this delegated regulation, radio equipment subject to the ‘common charger’ rules must incorporate the harmonised charging solution up to their maximum charging power or up to 240W if their maximum charging power is above 240W (as opposed to 100W in the previous versions of the standards concerned).

    The Commission will continue to update the technical specifications set out in Annex Ia, in order to reflect scientific and technological progress or market developments provided that such developments meet the objectives of the common charging solution.

    But then also

    1. Are proprietary charging receptacles allowed in addition to a USB-C receptacle?

    Yes. The RED only requires radio equipment subject to the ‘common charger’ rules to be equipped with the USB-C receptacle. The use of other receptacles is therefore not prohibited as long as the covered radio equipment is also equipped with a harmonised charging (USB-C) receptacle.

    That means those hefty laptops going up to 350 W or whatever, now need to accept 240 W over USB PD, but they may still include additional proprietary charging solutions that are rated higher.

    Also I don’t think the 100 W limit that some outlets report is actually in force since 2023/1717 has replaced the references to ‘EN IEC 62680-1-3:2021’ by those to ‘EN IEC 62680-1-3:2022’

    Reading on, yes they make that explicit further down:

    1. Is a radio equipment allowed to charge above 240 W when using an additional charging protocol?

    Yes. If the radio equipment proprietary charging solution requires more than 240 W (e.g. 300 W), the concerned radio equipment must also support USB PD up to 240W.

    The Commission has updated, via Commission Delegated Regulation (EU) 2023/1717, the references to the standards cited in Annex Ia to the latest version of the European standards. The updated version of the standards will apply as of the date of applicability of the relevant rules introduced to the RED by the Common Charger Directive, i.e. for handheld mobile phones, tablets, digital cameras, headphones, headsets, handheld videogame consoles, portable speakers, e-readers, keyboards, mice, portable navigation systems and earbuds, as of 28 December 2024 and, for laptops, as of 28 April 2026. This means that as from those dates a radio equipment, if it listed in Annex Ia and is capable to be recharged by means of wired charging at power above 240 W, must incorporate the harmonised charging solution up to 240 W.

    The Commission will continue to update the technical specifications set out in Annex Ia, in order to reflect scientific and technological progress or market developments provided that they meet the objectives of the common charging solution.








  • What’s reason we are talking about Signal here.

    That’s very easy to answer. Signal comes up here because that’s what actually happened in the case that brought the bug to light.

    The FBI recovered message content from the Apple notification service that happened to come from Signal, and used it to secure a conviction against people who used Signal in planning their anti-ICE activities

    Unlucky for Signal from a PR perspective but that’s just what actually happened, so people write about that rather than hypotheticals where other encrypted messaging apps would have suffered the same issue.








  • She answered that in her blog post that the Phoronix article links to:

    Which GPUs does this work with? Is it only AMD GPUs?

    Whether or not your GPU can benefit from it depends on the kernel driver - more specifically, whether it sets up the dmem cgroup controller.

    amdgpu and xe both have support for the dmem cgroup controller already. In theory, Intel GPUs running the xe kernel driver should benefit as well, although I’m not sure anyone tested this yet.

    For nouveau, I have sent a patch for dmem cgroup support to the mailing lists. This patch is also included in my development branch, so if you use my AUR package it should work. In other cases, you will need to wait for the patch to be picked up by your distribution, or apply it yourself.

    The proprietary NVIDIA kernel modules do not support dmem cgroups yet, so this won’t work there.
