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.
