Fixed the glk degamma lut programming which currently was hard coding a linear lut all the time, making degamma block of glk basically a pass through. Currently degamma lut for glk is assigned as 0 in platform configuration. Updated the same to 33 as per the hardware capability. IGT tests for degamma were getting skipped due to this, spotted by Swati. ToDo: The current gamma/degamm lut ABI has just 16bit for each color component. This is not enough for GLK+, since input precision is increased to 3.16 which will need 19bit entries. v2: Added Matt's RB. v3: Changed uint32_t to u32. v4: Fixed Maarten's review comment Credits-to: Swati Sharma <swati2.sharma@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1549893025-21837-2-git-send-email-uma.shankar@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.
