Overview

Conceptual documentation for the Pantavisor runtime and the meta-pantavisor layer. Start here before reading the build or install guides.

Topics

1. Pantavisor — what Pantavisor is: container model, atomic updates, cloud control, and the trail/revision system
2. meta-pantavisor — directory layout, key recipes, BitBake classes, KAS fragments, and layer conventions
3. Build System — KAS configuration hierarchy, multiconfig architecture, and the relationship between build targets
4. Boot Flow — how boot.cmd.pvgeneric boots Pantavisor: FIT/trail loading, try-boot, MMC vs NAND/UBIFS, and PV_BOOT_OEMARGS
5. CI — how CI machines, workflows, and build matrix relate to the layer structure
