CapDL API Proofs

This proof develops a formal API description for a number of the seL4 system calls, of the capDL kernel specification. This API description is a set of lemmas describing the behaviour of various system calls in terms of a separation logic defined over that kernel specification.

When reasoning about system calls this proof treats the kernel like a library invoked directly from user-space and does not reason about scheduling. These proofs are used by the system initialiser proof, as described in the ICFEM '13 paper and Andrew Boyton's PhD thesis.
