Improve AES/XTS performance of 6-way unrolling for PowerPC up to 17% with tcrypt. This is done by using one instruction, vpermxor, to replace xor and vsldoi. The same changes were applied to OpenSSL code and a pull request was submitted. This patch has been tested with the kernel crypto module tcrypt.ko and has passed the selftest. The patch is also tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled. Signed-off-by: Danny Tsen <dtsen@linux.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
