drm/i915: Split color mgmt based on single vs. double buffered registers
Split the color management hooks along the single vs. double buffered registers line. Of the currently programmed registers GAMMA_MODE and the ilk+ pipe CSC are double buffered, the LUTS and CHV CGM block are single buffered. The double buffered register will be programmed during the normal pipe update with evasion, and also during pipe enable so that the settings will already be correct when the pipe starts up before the planes are enabled. The single buffered registers are currently programmed before the vblank evade. Which is totally wrong, but we'll correct that later. v2: Add some docs to explain the two vfuncs (Matt,Uma) Rebase Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190205160848.24662-6-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@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.
