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. |

|
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.
