Definition in file rte_crc_arm64.h.
Function Documentation
static void rte_hash_crc_set_alg |
( |
uint8_t |
alg | ) |
|
|
inlinestatic |
Allow or disallow use of arm64 SIMD instrinsics for CRC32 hash calculation.
- Parameters
-
alg | An OR of following flags:
- (CRC32_SW) Don't use arm64 crc intrinsics
- (CRC32_ARM64) Use ARMv8 CRC intrinsic if available

inlinestatic |
Use single crc32 instruction to perform a hash on a 1 byte value. Fall back to software crc32 implementation in case arm64 crc intrinsics is not supported
- Parameters
-
data | Data to perform hash on. |
init_val | Value to initialise hash generator. |
- Returns
- 32bit calculated hash value.
