Miller" <davem@...emloft.net>, Ralf Baechle <ralf@...ux-mips.org>, David Daney <david.daney@...ium.com>, linux-crypto@...r.kernel.org, linux-mips@...ux-mips.org, linux-kernel@...r.kernel.org Cc: Aaro Koskinen <aaro.koskinen@....fi> Subject: [PATCH 0/5] MIPS/crypto: MD5 for OCTEON 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 A.
