This patch is a CE-optimized assembly implementation for cmac/xcbc/cbcmac. Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 300 mode of tcrypt, and compared the performance before and after this patch (the driver used before this patch is XXXmac(sm4-ce)). The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: Before: update-size | 16 64 256 1024 2048 4096 8192 ---------------+-------------------------------------------------------- cmac(sm4-ce) | 293.33 403.69 503.76 527.78 531.10 535.46 535.81 xcbc(sm4-ce) | 292.83 402.50 504.02 529.08 529.87 536.55 538.24 cbcmac(sm4-ce) | 318.42 415.79 497.12 515.05 523.15 521.19 523.01 After: update-size | 16 64 256 1024 2048 4096 8192 ---------------+-------------------------------------------------------- cmac-sm4-ce | 371.99 675.28 903.56 971.65 980.57 990.40 991.04 xcbc-sm4-ce | 372.11 674.55 903.47 971.61 980.96 990.42 991.10 cbcmac-sm4-ce | 371.63 675.33 903.23 972.07 981.42 990.93 991.45 Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
