fourier — per-host status

Snapshot of where fourier packages are installed / built across the fleet, as of 2026-04-28 evening. Index: fourier.

Reference target. The host where end-to-end validation lives.

• chromium-fourier-149-r3
• qt6-base-fourier 1:6.11.0-2
• kwin-fourier 1:6.6.4-1 (the upstream-shape 0002 patch)

End-to-end validated: bbb_1080p30_h264.mp4 plays smooth on KDE Plasma 6.6.4 Wayland with ~81 % combined chrome CPU. Brave's YouTube also feels snappier as a side-effect of the panfrost external_only + KWin dmabuf-fd-poll changes.

Mainline kernel 6.19.10. See also PineTab2 DDR overclock — independent workstream on the same host.

• qt6-base-fourier
• kwin-fourier (0002 upstream-shape)
• firefox-fourier 150.0.1

Confirms the qt6-base-fourier and kwin-fourier patches generalise across two different Mali generations (G52 on ohm, T860 on fresnel) — both go through panfrost.

Mesa pinned to 26.0.3 via IgnorePkg. Mesa 26.0.5 introduced a panfrost GLX regression on Mali-T860 that crashes sddm-greeter-qt6. This is separate from fourier work, captured during today's Syyuu.

xorg-server was downgraded to 21.1.21 during the mesa diagnosis. It is innocent in the regression and can be re-upgraded when convenient.

aarch64 build host. Builds the .pkg.tar.zst artifacts for:

• firefox-fourier
• qt6-base-fourier
• kwin-fourier

Cross-namespace context: see Project Volta — Radxa Rock 5 ITX+ / boltzmann stack.

Cross-compiles chromium-fourier (currently 149-r3). Container hosted on data — wake data first if it is asleep (sudo /opt/herding/bin/wake-data on hertz).

Currently DOWN. Planned for chromium-fourier RK3588 replication once back online. Not blocked on fourier — see MegabitChip for the DDR-init RE workstream that ampere is the primary target of.
