Highlights

AMD Ryzen-AI / NPU stack

NPU-first LLM tooling for AMD Ryzen AI (XDNA2). Application layer plus the driver and runtime it needs:

Speech / audio ML stack

ASR, speaker diarization, and audio DSP packages:

PyTorch / ONNX ecosystem additions

General-purpose ML infrastructure not covered by ::gentoo, pulled in alongside the speech stack above and broadly useful on their own:

ROCm 7.2.3

Local bumps of the ROCm 7.2 stable line ahead of ::gentoo's 7.2.0: dev-libs/rocm-{core,comgr,device-libs,opencl-runtime}, dev-libs/rccl, dev-libs/hipother, dev-build/rocm-cmake, dev-util/{hip,hipcc,hipify-clang,rocm-smi,rocminfo,rocm_bandwidth_test}, sci-libs/{hipBLAS,hipBLAS-common,hipBLASLt,hipCUB,hipFFT,hipRAND,hipSOLVER,hipSPARSE,hipsparselt,composable-kernel,miopen,rocBLAS,rocFFT,rocPRIM,rocRAND,rocSOLVER,rocSPARSE,rocThrust}.

dev-util/therock-bin is a /opt-installed ROCm SDK that pulls AMD's nightly TheRock build for a per-host AMDGPU_TARGETS. Coexists with the /usr ROCm above; an nvchecker regex source on AMD's CDN tracks new nightlies.

HyperSpy / 4D-STEM electron-microscopy stack

A full HyperSpy ecosystem that is not in ::gentoo:

hyperspy, hyperspyui, hyperspy-gui-traitsui, hyperspy-gui-ipywidgets, rosettasciio, emdfile, ncempy, exspy, atomap, pyxem, py4dstem.

Packaging follows upstream's split into a core (hyperspy) plus GUI backends and per-domain extensions (exspy for EELS/EDS, atomap for atomic-column analysis, pyxem / py4dstem for 4D-STEM, ncempy/emdfile/rosettasciio for I/O).

SANS / SAXS / XAFS analysis

  • sci-physics/mantid — SANS reduction and analysis. Installs under /opt/mantid and keeps building against the current ::gentoo by carrying a few local deps (see Qt5 revivals below).
  • sci-physics/sasview + dev-python/sasmodels
    • dev-python/bumps + dev-python/periodictable — SAS modeling and fitting.
  • sci-libs/ausaxs + dev-python/pyausaxs — AUSAXS solvent-scattering calculator and its Python bindings.
  • sci-physics/xraylarch — XAFS analysis; modern replacement for the discontinued ifeffit.
  • sci-physics/demeter — classic Athena/Artemis XAFS GUIs (Perl).

DeaDBeeF plugin collection

Twenty-six media-plugins/deadbeef-* packages, covering audio format support (opus, vgmstream, vfs-rar, archive-reader, bs2b), visualization (spectrogram, musical-spectrum, vu-meter, dr-meter, waveform-seekbar), playback/session control (playback-order, playback-status, headerbar, quick-search, rating, replaygain-control), file browsing (fb, bookmark-manager), desktop integration (gnome, statusnotifier, discord-presence) and output plumbing (jack, pulse2, stereo-widener, copy-info, customizable-toolbar).

Micromagnetism

sci-physics/mumax (GPU finite-difference, Go + CUDA), sci-physics/oommf (Tcl/Tk reference implementation), and sci-physics/vampire (atomistic spin dynamics).

Design choices

Python 2 preservation

::gentoo removed Python 2 support in 2024. sci-visualization/gwyddion 2.x ships pygwy, Python 2 bindings used by user analysis scripts; Gwyddion 3's GI bindings don't yet cover everything pygwy exposes, so those scripts still need a py2 runtime. This overlay vendors a small Python 2 surface to keep them working:

  • Locally-vendored eclasses in eclass/: distutils-r1_py2, python-r1_py2, python-single-r1_py2, python-utils-r1_py2. Inheriting one of these is the signal that a package is intentionally pinned to py2.
  • py2 forks of core libs under dev-python/*-python2: numpy-python2, certifi-python2, setuptools-python2, setuptools_scm-python2, pycairo-python2. Named distinctly so they can coexist with the py3 versions from ::gentoo.
  • py2-only legacy packages kept as-is: pygobject-2.28.6, pygtk-2.24.0, unittest-or-fail.

Expected pkgcheck warnings from this corner (UnderscoreInUseFlag, PythonMismatchedPackageName, RequiredUseDefaults) are suppressed globally in metadata/pkgcheck.conf with a comment explaining why.

Qt5 revivals for mantid

::gentoo finished its Qt5→Qt6 migration for x11-libs/qscintilla and dev-qt/qthelp, but sci-physics/mantid is still a Qt5 consumer upstream. To keep mantid working, this overlay revives two packages from ::gentoo's attic:

  • x11-libs/qscintilla-2.14.1-r1 (the last Qt5-compatible slot), with =x11-libs/qscintilla-2.14.1-r2 (Qt6-only) masked in profiles/package.mask.
  • dev-qt/qthelp-5.15.18.

These masks will lift once mantid finishes its own Qt6 port upstream.

Other targeted fixes kept in-tree

  • sci-libs/hdf 4.2.16 / 4.3.1 — local bumps; 4.2.16 carries a gcc 15 build fix, 4.3.1 is ahead of ::gentoo's 4.2.15-r2.
  • x11-libs/gtk+-2.24.33-r99 — gtk+:2 holdover for apps that still need it.
  • dev-python/bokeh — 2.4.2 dropped, 3.4.1 and 3.9.0 kept with the deprecated flaky test dep removed.
  • dev-python/py4dstem 0.14.18 — carries upstream PR #712 for numpy 2 compatibility.
  • dev-python/cupy 13.6.0 / 14.0.1 — ROCm USE flag dropped from 13.6.0 (cupy 13's HIP backend is incompatible with ROCm 7.x hipBLAS); cupy 14 dropped ROCm support entirely upstream.
  • Several media-plugins/deadbeef-* plugins carry patches for DeaDBeeF's modernized C API.

Repository layout and conventions

  • Thin manifests, masters = gentoo only. Every package depends on ::gentoo being enabled.
  • Profiles under profiles/ follow standard PMS layout.
  • Patches live in <category>/<package>/files/ and are applied via PATCHES=() or src_prepare().
  • Commit messages use subject + body form (72-char subject, blank line, rationale). Single-line messages only for truly trivial edits.
  • metadata/pkgcheck.conf documents which checks are suppressed and why (not just that they're suppressed).
  • CI runs pkgcheck scan on every PR and push (delta only), plus a full --net scan every three days via scheduled workflow.
