The setting of MSA is done by the DDI .pre_enable() hook. And when we are using MST, the MSA is only set to first mst stream by calling of DDI .pre_eanble() hook. It raies issues to non-first mst streams. Wrong MSA or missed MSA packets might show scrambled screen or wrong screen. This splits a setting of MSA to MST and SST cases. And In the MST case it will call a setting of MSA after an allocating of Virtual Channel from MST encoder pre_enable callback.

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.
