In XE, display runtime suspend / resume routines are called only if d3cold is allowed. This makes the driver unable to detect any HPDs once the device goes into runtime suspend state in platforms like LNL. Update the display runtime suspend / resume routines to include HPD polling regardless of d3cold status. While xe_display_pm_suspend/resume() performs steps during runtime suspend/resume that shouldn't happen, like suspending MST and they are missing other steps like enabling DC9, this patchset is meant to keep the current behavior wrt. these, leaving the corresponding updates for a follow-up v2: have a separate function for display runtime s/r (Rodrigo) v3: better streamlining of system s/r and runtime s/r calls (Imre) v4: rebased Reviewed-by: Arun R Murthy <arun.r.murthy@intel.com> Signed-off-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240823112148.327015-4-vinod.govindapillai@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.
