Replaces wm.max_level with wm.num_levels, since that generally results in nicer looking code (for-loops can be in standard form etc.). Also get rid of the two different wrappers we have for this (ilk_wm_max_level() and intel_wm_num_levels()). They don't really do anything for us other than potentially slow things down if the compiler actually emits the function calls every time (num_planes*num_wm_levels*higher_level_wm_function_calls could be a big number). The watermark code already shows up far too prominently in cpu profiles. Though I must admit that I didn't look at the generated code this time. v2: Fix the ilk_wm_merge() off-by-one (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230209222504.31478-1-ville.syrjala@linux.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.
