Emacs LLM policy fight and DRM kernel work

Emacs developers spent the day arguing over whether large language model contributions should be banned outright, while kernel graphics lists carried several substantial DRM series. Desktop users also saw Dolphin regain a long-missing view and Blender gather feedback on new lighting nodes.

Emacs developers debate a permanent ban on LLM contributions

A 150-message thread on emacs-devel, with 25 participants, debated a permanent ban on contributions produced by large language models. The argument cited review burden and community harm beyond copyright. The discussion was heated and is a governance question for how the project treats machine-written patches.

ELPA submission of an LLM-written spellchecker reopens policy questions

An ELPA submission of vibe-spell, described as an LLM-written spellchecker, drew 82 messages from 18 participants. The thread turned into a policy debate on maintenance and naming rather than a routine package review. It matters because it tests whether Emacs package infrastructure will accept machine-authored code under current rules.

DRM panel series adds opt-in atomic state access

A 35-patch series on dri-devel proposes letting DRM panels use atomic state by routing through an embedded drm_bridge. The change is opt-in for drivers. Nine participants discussed the series over 62 messages, so panel drivers that adopt it would gain the same atomic-state path as other KMS objects.

Dolphin restores Columns view

A KDE developer announced that the Columns (Miller) view mode has been restored to the Dolphin file manager. A 27-message thread with 16 participants discussed bugs and refinements. Users who relied on that layout get it back, with remaining polish still under discussion.

Blender Material Lighting Nodes draw wide feedback

A proposal thread on Blender's developer forum, 132 messages from 34 participants, collected feedback on new Material Lighting Nodes. Discussion covered NPR lighting limits and planned AOV support. The volume of replies suggests the nodes will shape how non-photoreal lighting is authored if the design holds.

Patch series proposes an atomic KMS reset flag

Version 10 of a small series proposes DRM_MODE_ATOMIC_RESET, plus helpers and tests, so userspace can atomically reset KMS object states to defaults. The thread was short, 12 messages between two participants. Compositors and test harnesses would get a defined way to return objects to defaults in one atomic commit if the flag lands.

dma-buf gains proposed memcg accounting and charge transfer

A v4 patchset adds memory-cgroup accounting and cross-cgroup charge transfer for dma-buf, with SELinux hooks and tests. Four participants exchanged 27 messages. The work would let graphics buffer memory be charged to the right cgroup and moved when ownership changes, which matters for containers and multi-user GPU hosts.

Qualcomm DCP display support proposed for MSM DRM

A v2 series of 23 patches adds a firmware-controlled DCP KMS backend to the MSM DRM driver via VirtIO and HFI. Review of the 65-message thread flagged multiple high-severity bugs. The series is the path to display support on that Qualcomm path, but reviewers have not signed off on the current code.
