Variables¶

uint64_t rte_get_tsc_hz (void)¶

Get the measured frequency of the RDTSC counter

Returns:

static uint64_t rte_get_tsc_cycles (void) [inline], [static]¶

Return the number of TSC cycles since boot

Returns:

static uint64_t rte_get_timer_cycles (void) [inline], [static]¶

Get the number of cycles since boot from the default timer.

Returns:

Definition at line 93 of file rte_cycles.h.

static uint64_t rte_get_timer_hz (void) [inline], [static]¶

Get the number of cycles in one second for the default timer.

Returns:

Definition at line 115 of file rte_cycles.h.

static void rte_delay_ms (unsigned ms) [inline], [static]¶

Wait at least ms milliseconds.

Parameters:

Definition at line 147 of file rte_cycles.h.

void rte_delay_us_block (unsigned int us)¶

Blocking delay function.

Parameters:

void rte_delay_us_sleep (unsigned int us)¶

Delay function that uses system sleep. Does not block the CPU core.

Parameters:

void rte_delay_us_callback_register (void(*)(unsigned int) userfunc)¶

Replace rte_delay_us with user defined function.

Parameters:

void(* rte_delay_us) (unsigned int us)¶

Wait at least us microseconds. This function can be replaced with user-defined function.
