The 128b/132b channel coding link training uses more straightforward TX FFE preset values. Reuse voltage tries and max vswing for retry logic. The delays for 128b/132b are still all wrong, but this is regardless a step forward. v2: Fix UHBR rate checks, use intel_dp_is_uhbr() helper v3: - Rebase - Modify intel_dp_adjust_request_changed() and intel_dp_link_max_vswing_reached() to take 128b/132b into account. (Ville) v4: - Train request printing for TX FFE (Ville) - Log 8b/10b vs. 128b/132b (Ville) - Add helper for per-lane max vswing / tx ffe (Ville) - Name functions with tx_ffe/vswing instead of 128b132b/8b10b Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211011182144.22074-2-jani.nikula@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.
