Gerwin Klein e54d98f025 aarch64 aspec+ainvs: adjust canonical_user to IPA 
Since user addresses are intermediate physical addresses in hyp mode,
the concept of canonical_user is different to other architectures.

The Machine Interface Specification of seL4

l4v/spec/machine/

This directory contains the Isabelle sources for the machine interface specification used in the abstract and design specifications of seL4.

Overview

  • ARMMachineTypes: ARM register set and related definitions.
  • MachineOps: definitions for the machine interface functions. Most interface functions are left non-deterministic. Some are assumed not to mutate C-observable state, others are defined in more detail.
  • MachineTypes: entry point to select a machine. Currently ARM only.
  • Platform: word size and other basic platform definitions.

Building

This module is not built in isolation, but included in the ASpec and ExecSpec sessions.

Remarks

  • the theory ARMMachineTypes is generated from Haskell using the tool in tools/haskell-translator and the skeleton file in spec/design/m-skel.
