Here are some tests on 2 Marvell SoC (I do not have dove platforms at hand and did not collect the results for A370): - Kirkwood 88F6282 (Feroceon 88FR131 rev 1) at 1.6GHz - Armada XP (mv78230, i.e. 2 core @1.2GHz) The targets are AES ECB and CBC encryption (decryption is similar performance-wise), done w/ tcrypt (mode=500 passed to tcrypt module). For each SoC, the various tests done by tcrypt are the following: AES ECB/CBC encryption: t 0 (128 bit key, 16 byte blocks) t 1 (128 bit key, 64 byte blocks) t 2 (128 bit key, 256 byte blocks) t 3 (128 bit key, 1024 byte blocks) t 4 (128 bit key, 8192 byte blocks) t 5 (192 bit key, 16 byte blocks) t 6 (192 bit key, 64 byte blocks) t 7 (192 bit key, 256 byte blocks) t 8 (192 bit key, 1024 byte blocks) t 9 (192 bit key, 8192 byte blocks) t 10 (256 bit key, 16 byte blocks) t 11 (256 bit key, 64 byte blocks) t 12 (256 bit key, 256 byte blocks) t 13 (256 bit key, 1024 byte blocks) t 14 (256 bit key, 8192 byte blocks) The three columns provide the value for software implementation (aes-asm), current driver (if available for that SoC), submitted v0. The percentage is the improvement against software implementation. soft current driver submitted v0 (if available) KW: ECB t 0: 5.23 MB/s 1.01 MB/s (-80.58%) 1.11 MB/s (-78.75%) t 1: 12.40 MB/s 3.70 MB/s (-70.16%) 4.14 MB/s (-66.59%) t 2: 18.94 MB/s 10.81 MB/s (-42.94%) 13.86 MB/s (-26.78%) t 3: 21.79 MB/s 20.69 MB/s (-5.05%) 33.80 MB/s (55.12%) t 4: 22.54 MB/s 25.97 MB/s (15.23%) 50.27 MB/s (123.05%) t 5: 5.00 MB/s 1.01 MB/s (-79.75%) 1.10 MB/s (-78.02%) t 6: 11.35 MB/s 3.70 MB/s (-67.41%) 3.84 MB/s (-66.17%) t 7: 16.60 MB/s 10.66 MB/s (-35.81%) 13.59 MB/s (-18.14%) t 8: 18.76 MB/s 20.13 MB/s (7.29%) 32.30 MB/s (72.15%) t 9: 19.20 MB/s 25.10 MB/s (30.74%) 47.11 MB/s (145.37%) t10: 4.85 MB/s 1.02 MB/s (-79.02%) 1.10 MB/s (-77.25%) t11: 10.50 MB/s 3.74 MB/s (-64.35%) 4.10 MB/s (-60.89%) t12: 14.80 MB/s 4.65 MB/s (-68.55%) 13.40 MB/s (-9.43%) t13: 16.47 MB/s 19.22 MB/s (16.69%) 31.14 MB/s (89.02%) t14: 16.89 MB/s 24.36 MB/s (44.18%) 44.33 MB/s (162.40%) CBC t 0: 4.78 MB/s 0.98 MB/s (-79.50%) 1.09 MB/s (-77.12%) t 1: 11.44 MB/s 3.59 MB/s (-68.62%) 4.07 MB/s (-64.41%) t 2: 17.66 MB/s 10.53 MB/s (-40.38%) 13.67 MB/s (-22.58%) t 3: 20.41 MB/s 20.42 MB/s (0.00%) 33.50 MB/s (64.10%) t 4: 21.14 MB/s 25.86 MB/s (22.36%) 50.02 MB/s (136.63%) t 5: 4.58 MB/s 0.98 MB/s (-78.64%) 1.08 MB/s (-76.31%) t 6: 10.54 MB/s 3.58 MB/s (-66.00%) 4.04 MB/s (-61.68%) t 7: 15.61 MB/s 10.39 MB/s (-33.49%) 13.40 MB/s (-14.16%) t 8: 17.73 MB/s 19.88 MB/s (12.10%) 32.04 MB/s (80.69%) t 9: 18.18 MB/s 25.02 MB/s (37.60%) 46.90 MB/s (157.97%) t10: 4.45 MB/s 0.98 MB/s (-77.96%) 1.09 MB/s (-75.62%) t11: 9.80 MB/s 3.60 MB/s (-63.28%) 4.03 MB/s (-58.83%) t12: 14.01 MB/s 4.34 MB/s (-69.01%) 13.24 MB/s (-5.48%) t13: 15.67 MB/s 19.44 MB/s (24.01%) 30.90 MB/s (97.17%) t14: 16.09 MB/s 24.28 MB/s (50.85%) 44.15 MB/s (174.34%) XP: ECB t 0: 8.85 MB/s 0.77 MB/s (-91.25%) t 1: 21.73 MB/s 3.09 MB/s (-85.79%) t 2: 34.81 MB/s 12.35 MB/s (-64.52%) t 3: 40.81 MB/s 38.68 MB/s (-5.22%) t 4: 42.69 MB/s 84.52 MB/s (98.00%) t 5: 8.55 MB/s 0.78 MB/s (-90.92%) t 6: 20.63 MB/s 3.11 MB/s (-84.92%) t 7: 31.47 MB/s 12.43 MB/s (-60.52%) t 8: 36.07 MB/s 38.08 MB/s (5.58%) t 9: 37.09 MB/s 80.43 MB/s (116.85%) t10: 8.25 MB/s 0.78 MB/s (-90.56%) t11: 19.19 MB/s 3.11 MB/s (-83.80%) t12: 28.61 MB/s 12.42 MB/s (-56.59%) t13: 32.49 MB/s 37.28 MB/s (14.74%) t14: 33.56 MB/s 77.11 MB/s (129.79%) CBC t 0: 8.20 MB/s 0.78 MB/s (-90.53%) t 1: 19.85 MB/s 3.10 MB/s (-84.36%) t 2: 31.60 MB/s 12.42 MB/s (-60.69%) t 3: 37.03 MB/s 38.70 MB/s (4.51%) t 4: 38.76 MB/s 84.05 MB/s (116.87%) t 5: 7.69 MB/s 0.78 MB/s (-89.90%) t 6: 18.62 MB/s 3.10 MB/s (-83.32%) t 7: 28.47 MB/s 12.40 MB/s (-56.44%) t 8: 32.73 MB/s 37.97 MB/s (16.02%) t 9: 33.73 MB/s 79.96 MB/s (137.07%) t10: 7.58 MB/s 0.77 MB/s (-89.88%) t11: 17.59 MB/s 3.07 MB/s (-82.56%) t12: 26.26 MB/s 12.28 MB/s (-53.23%) t13: 29.89 MB/s 37.02 MB/s (23.87%) t14: 30.87 MB/s 76.70 MB/s (148.45%) Cheers, a+ -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
