This patch is a CE-optimized assembly implementation for CTS-CBC mode.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 218 mode of
tcrypt, and compared the performance before and after this patch (the driver
used before this patch is cts(cbc-sm4-ce)). The abscissas are blocks of
different lengths. The data is tabulated and the unit is Mb/s:
Before:
cts(cbc-sm4-ce) | 16 64 128 256 1024 1420 4096
----------------+--------------------------------------------------------------
CTS-CBC enc | 286.09 297.17 457.97 627.75 868.58 900.80 957.69
CTS-CBC dec | 286.67 285.63 538.35 947.08 2241.03 2577.32 3391.14
After:
cts-cbc-sm4-ce | 16 64 128 256 1024 1420 4096
----------------+--------------------------------------------------------------
CTS-CBC enc | 288.19 428.80 593.57 741.04 911.73 931.80 950.00
CTS-CBC dec | 292.22 468.99 838.23 1380.76 2741.17 3036.42 3409.62

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.
