This patch adds the NEON acceleration implementation of the SM3 hash algorithm. The main algorithm is based on SM3 NEON accelerated work of the libgcrypt project. Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 326 mode of tcrypt, and compares the performance data of sm3-generic and sm3-ce. The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: update-size | 16 64 256 1024 2048 4096 8192 ---------------+-------------------------------------------------------- sm3-generic | 185.24 221.28 301.26 307.43 300.83 308.82 308.91 sm3-neon | 171.81 220.20 322.94 339.28 334.09 343.61 343.87 sm3-ce | 227.48 333.48 502.62 527.87 520.45 534.91 535.40 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.
