Subject[PATCH 0/5] MIPS/crypto: MD5 for OCTEON
Date
Hi,

This adds accelerated MD5 cryptoapi module for OCTEON.

Tested with 3.19-rc1 on EdgeRouter Lite (OCTEON+) and EdgeRouter Pro
(OCTEON2) by running selftest, tcrypt and also by sending TCP MD5SIG
traffic between OCTEON <-> X86 box.

Below figures show the improvement on ER Lite compared to md5-generic
(calculated from output of tcrypt mode=402).

test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 1.20x faster
test 1 ( 64 byte blocks, 16 bytes per update, 4 updates): 1.17x faster
test 2 ( 64 byte blocks, 64 bytes per update, 1 updates): 1.30x faster
test 3 ( 256 byte blocks, 16 bytes per update, 16 updates): 1.14x faster
test 4 ( 256 byte blocks, 64 bytes per update, 4 updates): 1.29x faster
test 5 ( 256 byte blocks, 256 bytes per update, 1 updates): 1.84x faster
test 6 ( 1024 byte blocks, 16 bytes per update, 64 updates): 1.13x faster
test 7 ( 1024 byte blocks, 256 bytes per update, 4 updates): 2.01x faster
test 8 ( 1024 byte blocks, 1024 bytes per update, 1 updates): 2.49x faster
test 9 ( 2048 byte blocks, 16 bytes per update, 128 updates): 1.13x faster
test 10 ( 2048 byte blocks, 256 bytes per update, 8 updates): 2.05x faster
test 11 ( 2048 byte blocks, 1024 bytes per update, 2 updates): 2.57x faster
test 12 ( 2048 byte blocks, 2048 bytes per update, 1 updates): 2.71x faster
test 13 ( 4096 byte blocks, 16 bytes per update, 256 updates): 1.15x faster
test 14 ( 4096 byte blocks, 256 bytes per update, 16 updates): 2.08x faster
test 15 ( 4096 byte blocks, 1024 bytes per update, 4 updates): 2.63x faster
test 16 ( 4096 byte blocks, 4096 bytes per update, 1 updates): 2.83x faster
test 17 ( 8192 byte blocks, 16 bytes per update, 512 updates): 1.13x faster
test 18 ( 8192 byte blocks, 256 bytes per update, 32 updates): 2.09x faster
test 19 ( 8192 byte blocks, 1024 bytes per update, 8 updates): 2.66x faster
test 20 ( 8192 byte blocks, 4096 bytes per update, 2 updates): 2.87x faster
test 21 ( 8192 byte blocks, 8192 bytes per update, 1 updates): 2.87x faster
