Linux kernel source tree

The dbuf state will be where we collect all the inter-pipe dbuf allocation stuff. Start by adding the actual per-pipe ddb entries there. Originally the plan was to move them there outright, but that no longer works as we're no longer guaranteed to have a dbuf state when it comes time to sanity check the ddb overlaps in skl_commit_modeset_enables(). I think when I wrote this originally we did the watermark/ddb calculation last, and so we couldn't have any crtcs in the state w/o also having the dbuf state. But that has since changed and we do the watermark/ddb calculation much earlier, and thus it is now possible to commit crtcs w/o a dbuf state. So we keep another copy of the information in the crtc state. v2: Rebase v3: Duplicate the entries instead of moving Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210122205633.18492-6-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.
