crypto: inside-secure - use the base_end pointer in ring rollback

2017-06-20T03:21:48+00:00

A base_end pointer is set and provided. Use it in the ring rollback
function to avoid using build-in defines.

crypto: inside-secure - increase the batch size

2017-06-20T03:21:47+00:00

Increase the batch size to the maximum number of requests a ring can
handle at a time (its size). This is possible now that the request
queues are per hw ring. This improves performances.

crypto: inside-secure - only dequeue when needed

2017-06-20T03:21:47+00:00

This force the need_dequeue flag to be unset whenever the dequeue
function is called, to avoid calling it when it is not necessary.

crypto: inside-secure - get the backlog before dequeueing the request

2017-06-20T03:21:46+00:00

Get the backlog before dequeuing the request otherwise we'll miss the
first request in line.

crypto: inside-secure - stop requeueing failed requests

2017-06-20T03:21:45+00:00

This update the dequeue function of the inside-secure safexcel driver so
that failed requests aren't requeued when they fail (for whatever
reason, which can be because the hw ring is full).

crypto: inside-secure - use one queue per hw ring

2017-06-20T03:21:45+00:00

Update the inside-secure safexcel driver from using one global queue to
one queue per hw ring. This ease the request management and keep the hw
in sync with what's done in sw.

crypto: inside-secure - update the context and request later

2017-06-20T03:21:44+00:00

This move the context and request updates at the end of the cipher and
hash send() functions. This way the context and request fields are set
only when everything else was successful in the send() functions.

crypto: inside-secure - align the cipher and hash send functions

2017-06-20T03:21:44+00:00

The cipher and hash send functions both set the results variable, to be
used later by the caller. Align the way they're setting this variable.

crypto: inside-secure - optimize DSE bufferability control

2017-06-20T03:21:44+00:00

Configure the data write bufferability to always buffer packets in the
DSE. This change slightly improves performance.

crypto: inside-secure - enable single WR in DSE configuration

2017-06-20T03:21:43+00:00

When enable_single_wr is not enabled, the DSE will only write those
parts of a result descriptor that need updating, which means a final
result descriptor will be written in 2 or 3 smaller transfers.
When enable_single_wr is enabled the DSE will combine these 2-3
updates into one large write transfer, generally improving performance.
