Every image records the identity of its build inputs. forgefirm-manifest.bbclass gives a component recipe a per-file source fingerprint (git ls-tree blob ids, submodules recursed; file:// sources hashed with git hash-object); the kernel and glowforge.ko publish theirs through do_deploy because kernel-module-split leaves the module recipe's main package empty. forgefirm-image-manifest.bbclass assembles the entries with the platform identity - machine, modules directory, device tree hashes, layer content hashes (meta-forgefirm and the meta-openglow layers by content, the kas-managed layers by revision) - into /etc/forgefirm-manifest.json and deploys a copy next to the image. Layer revisions and dirty flags stay outside the identity, so a rebuild from an unchanged tree keeps its content hash and the release and dev images of one build share it. The acceptance tool and the release gate read this file.

DESCRIPTION = "OpenGlow/ForgeFIRM image for Glowforge"
|
|
|
|
# ForgeFIRM cuts the cloud dependency: drop the Glowforge cloud client
|
|
# (gfui-client connects to Glowforge's servers). Removing it here (override
|
|
# only; the shared glowforge-image base is untouched) also sidesteps its
|
|
# do_package failure. Its role is filled locally by forgectrl and the
|
|
# controllers below (kas/README.md backlog #6).
|
|
IMAGE_INSTALL:remove = "gfui-client"
|
|
|
|
# grblhal-glowforge: the grblHAL motion controller (Grbl over TCP:23).
|
|
# forgectrl: the ForgeFIRM machine-services daemon (HTTP :8080): controller
|
|
# supervisor, pulse-device broker, cooling engine, cameras, telemetry,
|
|
# settings, diagnostics, web control panel, and A/B updates.
|
|
# gfhome: one-shot Glowforge web-service homing, invoked by the controller
|
|
# for $H when homing_mode = gfcloud (/data/forgefirm.conf).
|
|
# gfcloud: full Glowforge web-service controller daemon (the factory cloud
|
|
# experience), started when controller_mode = cloud - mutually exclusive with
|
|
# grblHAL. Pulls python3-ffmachine (shared web-service machine glue).
|
|
# v4l-utils provides media-ctl / v4l2-ctl for the imx-media pipeline (also a
|
|
# forgectrl runtime dependency, kept explicit here for bring-up use).
|
|
# fwup: applies signed .fw archives (ForgeFIRM upgrades + factory restore)
|
|
# to the inactive rootfs slot.
|
|
# ffboot: boot-slot inventory and switching (also ships fw_env.config).
|
|
# slotmigrate: boot-time reclaim of the legacy p4 layout (grows /data).
|
|
# forgefirm-logging: the ForgeFIRM logging tree - renders the per-logger
|
|
# rsyslog rules from the settings before rsyslog starts, and drives
|
|
# size-capped rotation (boot + hourly; a full /data breaks settings,
|
|
# updates, and controller writes). rsyslog itself comes in through
|
|
# VIRTUAL-RUNTIME_base-utils-syslog (conf/distro/forgefirm.conf).

# the build fails rather than emit an unflashable image. The raw ext4 is

# deployed alongside the wic; scripts/mkfw.sh packs it into the signed

# .fw release artifact.
