Instead of reading job ring's occupancy registers for every req/rsp enqueued/dequeued respectively, we read these registers once and store them in memory. After completing a job enqueue/dequeue, we decrement these values. When these values become zero, we refresh the snapshot of job ring's occupancy registers. This eliminates need of expensive device register read operations for every job enqueued and dequeued and hence makes caam_jr_enqueue() and caam_jr_dequeue() faster. The performance of kernel ipsec improved by about 6% on ls1028 (for frame size 408 bytes).

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.
