| 2024-02-16 | s390/checksum: provide csum_partial_copy_nocheck() | Heiko Carstens | |
| With csum_partial(), which reads all bytes into registers it is easy to also implement csum_partial_copy_nocheck() which copies the buffer while calculating its checksum. For a 512 byte buffer this reduces the runtime by 19%. Compared to the old generic variant (memcpy() + cksm instruction) runtime is reduced by 42%).

| 2024-02-16 | s390/checksum: provide vector register variant of csum_partial() | Heiko Carstens | |
| Provide a faster variant of csum_partial() which uses vector registers instead of the cksm instruction. Signed-off-by: Heiko Carstens <hca@linux.ibm.com> | |||
