Function Documentation
static void rte_pause (void) [inline], [static]
Pause CPU execution for a short while
This call is intended for tight loops which poll a shared resource or wait for an event. A short pause within the loop may reduce the power consumption.
static __rte_always_inline void rte_wait_until_equal_16 (volatile uint16_t * addr, uint16_t expected, rte_memory_order memorder) [static]
Wait for *addr to be updated with a 16-bit expected value, with a relaxed memory ordering model meaning the loads around this API can be reordered.
Parameters
addr A pointer to the memory location.
expected A 16-bit expected value to be in the memory location.
memorder Two different memory orders that can be specified: rte_memory_order_acquire and rte_memory_order_relaxed.

static __rte_always_inline void rte_wait_until_equal_32 (volatile uint32_t * addr, uint32_t expected, rte_memory_order memorder) [static]
Wait for *addr to be updated with a 32-bit expected value, with a relaxed memory ordering model meaning the loads around this API can be reordered.
Parameters
addr A pointer to the memory location.
expected A 32-bit expected value to be in the memory location.
memorder Two different memory orders that can be specified: rte_memory_order_acquire and rte_memory_order_relaxed.

static __rte_always_inline void rte_wait_until_equal_64 (volatile uint64_t * addr, uint64_t expected, rte_memory_order memorder) [static]
Wait for *addr to be updated with a 64-bit expected value, with a relaxed memory ordering model meaning the loads around this API can be reordered.
Parameters
addr A pointer to the memory location.
expected A 64-bit expected value to be in the memory location.
memorder Two different memory orders that can be specified: rte_memory_order_acquire and rte_memory_order_relaxed.
