SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. The current implementation is aligned with previous Intel solutions, but is not optimal and can be improved: a) for every get/put the host wakes up the DSP and generates an IPC. The kernel should cache the values and generate an IPC only when strictly necessary. b) the firmware can be implemented to only instantiate the pipelines and related control-related parts that are needed at a given time, and power-gate the relevant SRAM blocks. The development tasks for these two improvements has started, once validated they will be provided in an update.

README
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.
