intel_wait_for_vblank() goes through a pipe to crtc lookup, while in most cases we already have the crtc available. Avoid the extra lookups by adding an intel_crtc based helper. v2: - Add intel_crtc_wait_for_next_vblank() helper (Ville) Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/90cfbd8c3e79a742b0ee9e3ae75493acb0785dbb.1638366969.git.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.
