Architecture

How GlassineOS is put together. Pages here describe the design; code-level details live in each repository's own docs/ and are linked from here.

Layer	What	Varies with
Bootstrap	bootloader, partition layout, recovery, flashing	device
Kernel	mainline fork with device patches, device trees	SoC family, board
Firmware	vendor firmware extracted from the device	device (never redistributed)
E-ink engine	drives the panel, chooses refresh modes, takes hints from apps	display pipeline
Desktop	sway with e-ink patches, shell, settings, keyboard	nothing (device config only)
Distribution	Alpine base, our package and Flatpak repositories, images, updates	release

Pages: Boot flow.

Planned pages: e-ink engine and its buffer protocol, the e-ink hint protocol, update model, storage and encryption, recovery, package repositories and signing.
