README.md

This proof demonstrates the memory safety of the TaskDelay function. We assume that pxCurrentTCB is initialized and inserted in one of the ready tasks lists (with and without another task in the same list). We abstract function xTaskResumeAll by assuming that xPendingReadyList is empty and xPendedTicks is 0. Finally, we assume nondeterministic values for global variables xTickCount and xNextTaskUnblockTime, and pdFALSE for uxSchedulerSuspended (to avoid assertion failure).

Configurations available:

  • default: The default configuration.
  • useTickHook1: The default configuration with INCLUDE_vTaskSuspend=0

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:

  • vPortEnterCritical
  • vPortExitCritical
  • vPortGenerateSimulatedInterrupt
