uint64_trte_get_tsc_hz(void)
       Get the measured frequency of the RDTSC counter

       Returns
           The TSC frequency for this lcore

   staticuint64_trte_get_tsc_cycles(void)[inline],[static]
       Return the number of TSC cycles since boot

       Returns
           the number of cycles

   staticuint64_trte_get_timer_cycles(void)[inline],[static]
       Get the number of cycles since boot from the default timer.

       Returns
           The number of cycles

       Definition at line 97 of file rte_cycles.h.

   staticuint64_trte_get_timer_hz(void)[inline],[static]
       Get the number of cycles in one second for the default timer.

       Returns
           The number of cycles in one second.

       Definition at line 119 of file rte_cycles.h.

   staticvoidrte_delay_ms(unsignedms)[inline],[static]
       Wait at least ms milliseconds.

       Parametersms The number of milliseconds to wait.

       Definition at line 151 of file rte_cycles.h.

   voidrte_delay_us_block(unsignedintus)
       Blocking delay function.

       Parametersus Number of microseconds to wait.

   voidrte_delay_us_sleep(unsignedintus)
       Delay function that uses system sleep. Does not block the CPU core.

       Parametersus Number of microseconds to wait.

   voidrte_delay_us_callback_register(void(*)(unsignedint)userfunc)
       Replace rte_delay_us with user defined function.

       Parametersuserfunc User function which replaces rte_delay_us. rte_delay_us_block restores builtin block delay
           function.
