In this patch, a vfunc read_luts() is introduced to create a hw lut i.e. lut having values read from gamma/degamma registers which will later be used to compare with sw lut to validate gamma/degamma lut values. v3: -Rebase v4: -Renamed intel_get_color_config to intel_color_get_config [Jani] -Wrapped get_color_config() [Jani] v5: -Renamed intel_color_get_config() to intel_color_read_luts() -Renamed get_color_config to read_luts v6: -Renamed intel_color_read_luts() back to intel_color_get_config() [Jani and Ville] Signed-off-by: Swati Sharma <swati2.sharma@intel.com> --- drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/gpu/drm/i915/intel_color.c | 8 ++++++++ drivers/gpu/drm/i915/intel_color.h | 1 + 3 files changed, 10 insertions(+)
