[PATCH 0/5] MIPS/crypto: MD5 for OCTEON

[Aaro Koskinen]

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
