There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called: 1- crtc enable 2- crtc disable 3- crtc vblank enable 4- crtc vblank disable When we enable or disable the crtc, we call drm_crtc_vblank_on and drm_crtc_vblank_off respectively. That will gate vblank enables and disables to only being called when the crtc is active. That means that we can just enable/disable pm runtime in crtc enable/disable. This will be beneficial in trying to eliminate blocking calls from the vblank call chain.

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.
