README.md

This proof demonstrates the memory safety of the TaskIncrementTick function. We assume that task lists are initialized and filled with a few list items. We also assign nondeterministic values to some global variables.

Configurations available:

  • default: The default configuration. useTickHook1: The default
  • configuration with configUSE_TICK_HOOK=1

This proof is a work-in-progress. Proof assumptions are described in the harness. The proof also assumes the following functions are memory safe and have no side effects relevant to the memory safety of this function:

  • prvTraceGetTaskNumber
  • prvTracePortGetTimeStamp
  • prvTraceStoreKernelCallWithNumericParamOnly
  • prvTraceStoreTaskReady
  • vApplicationTickHook
