Currently we have had an artificial limitation of a single DMA tunnel per XDomain connection. However, hardware wise there is no such limit and software based connection manager can take advantage of all the DMA rings available on the host to establish tunnels. For this reason make the tb_xdomain_[enable|disable]_paths() to take the DMA ring and HopID as parameter instead of storing them in the struct tb_xdomain. We also add API functions to allocate input and output HopIDs of the XDomain connection that the service drivers can use instead of hard-coding. Also convert the two existing service drivers over to this API. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
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.
