Storage and filesystems¶
Block devices, ATA/AHCI/NVMe/VirtIO concepts, sectors, DMA, filesystem structures, journaling, ChrisFS and installation.
Scope¶
This volume defines the terminology and relationships required before implementation detail. General concepts remain separate from ChrisOS-specific decisions; when a chapter crosses into implementation, its source revision and relevant files are declared in frontmatter.
Core chapters¶
- Block storage stack
- ChrisFS
Reading rule¶
Lower-layer details need not be memorized, but terms used by higher layers are defined before their first technical use. Diagrams show flow and responsibility; tables record contracts, layouts and states.
