Currently, we rely on the generic CTS chaining mode wrapper to instantiate the cts(cbc(aes)) skcipher. Due to the high performance of the ARMv8 Crypto Extensions AES instructions (~1 cycles per byte), any overhead in the chaining mode layers is amplified, and so it pays off considerably to fold the CTS handling into the SIMD routines. On Cortex-A53, this results in a ~50% speedup for smaller input sizes. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> 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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
