Linux kernel source tree

Adding link rate and lane count information to i915_display_info makes it easier and faster to access this data compared to checking kernel logs. This is particularly beneficial for individuals who are not familiar with i915 in the following scenarios: * Debugging DP tunnel bandwidth usage in the Thunderbolt driver. * During USB4 certification, it is necessary to know the link rate used by the monitor to prove that the DP tunnel can handle required rates. * In PHY CTS, when the connector probes are not mounted correctly, some display lanes may not appear in the DP Oscilloscope, leading to CTS failures. This change provides validation teams with an easy way to identify and troubleshoot issues. v2: separate seq_printf line (Jani) v3: separate output line (Jani) Cc: Imre Deak <imre.deak@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://lore.kernel.org/r/20250409230214.963999-1-khaled.almahallawy@intel.com Signed-off-by: Jani Nikula <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 reStructuredText 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.
