Advanced Peios
The deeper end of Peios — internals and behaviour beyond everyday operation.
Topics
Peios Core Specification Anthology (PCSA)
-
Conventions
Conventions for Specifications and TRMs
How the documents of this anthology are written and read — normative language, required structure, citation and addressing, and the style rules for specifications and for technical reference manuals.
-
PCDS
Peios Common Data Structures
The common binary data structures shared across Peios subsystems: the GUID, LUID, and SID identifier types, and the security descriptor family.
-
PGSS
Peios Generic System Standards
The cross-platform standards a system must implement to be Peios — contracts between two roles, either of which a third party may replace.
-
PSPK
Peios System Protocols Kernel
The contracts spoken across the kernel boundary — the protocols a Peios kernel subsystem depends on a userspace process to fulfil, and the formats it exchanges with one.
-
PSPU
Peios System Protocols Userspace
The foundational userspace protocols — public, stable contracts between the components a Peios system is built from, which third parties may implement.
