[Why] As it stands, psr has feature flags in dm, stream, and link. Most are not defined well enough, and different dm layers have different uses for these same flags. [How] We define a new structure called psr_settings in dc_link that will hold the following psr feature flags: psr_feature_enable - psr is supported psr_allow_active - psr is currently active psr_version - internal psr version supported psr_frame_capture_indication_req psr_sdp_transmit_line_num_deadline The last two flags were moved out of the power module for the purposes of consolidating psr flags. Their use is already well-defined. Psr caps reported by sink will also be stored in dc_link, in dpcd_caps.psr_caps.

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.
