[PATCH 2/3] Add initial color management framework code

Wed Apr 24 06:58:03 PDT 2013


ICC profiles can now be specified in weston.ini for each output, or a CMS
implementation can optionally loaded from a pluggable module.

+/* General overview on how to be a CMS plugin:
+ *
+ * First, some nomenclature:
+ *
+ *  CMF:       Color management framework, i.e. "Use foo.icc for device $bar"
+ *  CMM:       Color management module that converts pixel colors, which is
+ *             usually lcms2 on any modern OS.
+ *  CMS:       Color management system that encompasses both a CMF and CMM.
+ *  ICC:       International Color Consortium, the people that define the
+ *             binary encoding of a .icc file.
+ *  VCGT:      Video Card Gamma Tag. An Apple extension to the ICC specification
+ *             that allows the calibration state to be stored in the ICC profile
+ *  Output:    Physical port with a display attached, e.g. LVDS1
+ *
+ * As a CMF is probably something you don't want or need on an embeded install
+ * these functions will not be called if the icc_profile key is set for a
+ * specific [output] section in weston.ini
+ *
+ * Most desktop environments want the CMF to decide what profile to use in
+ * different situations, so that displays can be profiled and also so that
+ * the ICC profiles can be changed at runtime depending on the task or ambient
+ * environment.
+ *
+ * The CMF can be selected using the 'cms' key in the [core] section.
+ * Specifying multiple CMFs will not work.
+ *
+ * The general idea is the compositor creates an output which is registered
+ * with the CMS using weston_cms_output_added(). This is expected to call
+ * the ->updated_color_profile() vfunc on the output with the prepared object
+ * of type weston_color_profile, or NULL if there is no color profile to apply.
+ *
+ * If the CMF can detect that the assigned ICC profile has changed for a
+ * specific output, then it can call the ->updated_color_profile() vfunc at any
+ * time until weston_cms_output_removed() is called.
+ *
+ * The updated_color_profile() vfunc is expected to set the output calibration
+ * state, typically by uploading the VCGT data to the graphics card using
+ * drmModeCrtcSetGamma()
