Add an implementation of the ChaCha20 stream cipher (see e.g. RFC 7539) that makes use of z13's vector instruction set extension. The original implementation is by Andy Polyakov which is adapted for kernel use. Four to six blocks are processed in parallel resulting in a performance gain for inputs >= 256 bytes. chacha20-generic 1 operation in 622 cycles (256 bytes) 1 operation in 2346 cycles (1024 bytes) chacha20-s390 1 operation in 218 cycles (256 bytes) 1 operation in 647 cycles (1024 bytes) Cc: Andy Polyakov <appro@openssl.org> Reviewed-by: Harald Freudenberger <freude@de.ibm.com> Signed-off-by: Patrick Steuer <patrick.steuer@de.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>

help
|
|
This sets the default maximum request size to perform AES requests
|
|
using software instead of the crypto engine. It can be changed by
|
|
setting the aes_sw_max_len parameter.
|
|
|
|
Small blocks are processed faster in software than hardware.
|
|
Considering the 256-bit ciphers, software is 2-3 times faster than
|
|
qce at 256-bytes, 30% faster at 512, and about even at 768-bytes.
|
|
With 128-bit keys, the break-even point would be around 1024-bytes.
|
|
|
|
The default is set a little lower, to 512 bytes, to balance the
|
|
cost in CPU usage. The minimum recommended setting is 16-bytes
|
|
(1 AES block), since AES-GCM will fail if you set it lower.
|
|
Setting this to zero will send all requests to the hardware.
|
|
|
|
Note that 192-bit keys are not supported by the hardware and are
|
|
always processed by the software fallback, and all DES requests
|
|
are done by the hardware.
