Function Documentation

int rttest_init(size_t iterations, struct timespec update_period, size_t sched_policy, int sched_priority, size_t stack_size, uint64_t prefault_dynamic_size, char *filename)

Initialize rttest. Preallocate the sample buffer, store user parameters, lock memory if necessary Not real time safe.

Parameters:

  • iterations – [in] How many iterations to spin for

  • update_period – [in] Time interval representing the spin period

  • sched_policy – [in] Scheduling policy, e.g. round robin, FIFO

  • sched_priority – [in] The thread priority

  • stack_size – [in] How many bytes to prefault when rttest_prefault_stack() is called.

  • prefault_dynamic_size – [in] How many bytes to prefault on the heap.

  • filename – [in] Name of the file to save results to.

Returns:

Error code to propagate to main
