README.md

CapDL User-level system initialiser

This contains a formalised algorithm and the proof of correctness of a user-level system initialiser that uses capDL to specify the state of the resultant system.

It builds on the CapDL API Proofs, and uses a separation logic defined for capDL.

The system initialiser and the proof are described in the ICFEM '13 paper and Andrew Boyton's PhD thesis.

Building

To build from the l4v/ directory, run:

make SysInit

To build the example capDL specifications, from the l4v/ directory, run:

make SysInitExamples

Important Theories

  • The specification for the algorithm of the system initialiser is in SysInit_SI.

  • The top-level statement of the correctness of the system-initialiser is found in Proof_SI.

  • The definition of what it means for an object to be initialised (object_initialised and (irq_initialised) is found in ObjectInitialised_SI.

  • Only "well-formed" capDL specifications can be initialised. The definition of well-formed is located in WellFormed_SI.

  • Two example capDL specifications that are "well-formed" are found in ExampleSpec_SI and ExampleSpecIRQ_SI. The former is a simple capDL spec, and the latter a more complicated specifications with IRQ support.
