[why] 1. HPD callback function has deadlock problem 2. HPD status is not assigned 3. There is crash due to null pointer 4. link_enc is NULL in DPIA case [How] 1. Fix deadlock problem by moving it out of the drm_modeset_lock 2. Assign HPD status from the notify of outbox from dmub FW 3. Fix the crash by checking if pin or enc exists 4. Use link_enc_cfg_get_link_enc_used_by_link to dynamically assign Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Acked-by: Wayne Lin <Wayne.Lin@amd.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Jude Shih <shenshih@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.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.
