Function Documentation

◆ rte_mov16()

static void rte_mov16	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 16 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

Examples: examples/l3fwd/l3fwd_fib.c.

◆ rte_mov32()

static void rte_mov32	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 32 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

◆ rte_mov48()

static void rte_mov48	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 48 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

◆ rte_mov64()

static void rte_mov64	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 64 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

◆ rte_mov128()

static void rte_mov128	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 128 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

◆ rte_mov256()

static void rte_mov256	(	uint8_t *	dst,
		const uint8_t *	src
	)

inlinestatic

Copy 256 bytes from one location to another using optimised instructions. The locations should not overlap.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.

◆ rte_memcpy()

static void * rte_memcpy	(	void *	dst,
		const void *	src,
		size_t	n
	)

static

Copy bytes from one location to another. The locations must not overlap.

Note: This is implemented as a macro, so it's address should not be taken and care is needed as parameter expressions may be evaluated multiple times.; For x86 platforms to enable the AVX-512 memcpy implementation, set -DRTE_MEMCPY_AVX512 macro in CFLAGS, or define the RTE_MEMCPY_AVX512 macro explicitly in the source file before including the rte_memcpy header file.

Parameters

dst	Pointer to the destination of the data.
src	Pointer to the source data.
n	Number of bytes to copy.

Returns: Pointer to the destination data.
