Disabling WM1+ on ICL causes tons of underruns with linear/X-tiled framebuffers. We can avoid this by flipping on a chicken bit affecting the way the hw fill the FIFO. This may not be the final solution but should hopefully avoid some underruns in the meantime. v2: Apparently PIPE_CHICKEN is icl+ only Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190204202232.27153-1-ville.syrjala@linux.intel.com Reviewed-by: Matt Roper <matthew.d.roper@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.
