This is done for legacy, i965, ilk, glk and their variant platforms. Intentionally, excluded bdw and ivb since they have spilt gamma mode; for which degamma read outs are required (which I think shouldn't be included in this patch series). Will include after degamma state checker is completed. v1: -Implementation done for legacy platforms (removed all the placeholders) (Jani) v2: -Restructured code and created platform specific patch series for gamma validation v3: -Rebase v4: -Minor changes-function name changes mainly v5: -Added degamma validation (Ville) v6: -Removed degamma changes, debugging was becoming difficult -Added function to assign bit_precision for gamma/degamma lut values /platform -Added debug info into intel_dump_pipe_config() (Jani) v7: -Added platform specific functions to compute gamma bit precision on the basis of GAMMA_MODE (Ville) -Corrected checkpatch warnings v8: -Restructured code -Removed bdw and ivb platform state checker v9: -Obliged 80 character word limit [Uma] -Added state checker for icl -Added bit precision func for icl Swati Sharma (11): drm/i915/display: Add func to get gamma bit precision drm/i915/display: Add debug log for color parameters drm/i915/display: Add func to compare hw/sw gamma lut drm/i915/display: Add macro to compare gamma hw/sw lut drm/i915/display: Extract i9xx_read_luts() drm/i915/display: Extract i965_read_luts() drm/i915/display: Extract chv_read_luts() drm/i915/display: Extract ilk_read_luts() drm/i915/display: Extract glk_read_luts() drm/i915/display: Extract icl_read_luts() FOR_TESTING_ONLY: Print rgb values of hw and sw blobs drivers/gpu/drm/i915/display/intel_color.c | 523 ++++++++++++++++++++++++++- drivers/gpu/drm/i915/display/intel_color.h | 7 + drivers/gpu/drm/i915/display/intel_display.c | 34 ++ drivers/gpu/drm/i915/i915_reg.h | 21 ++ 4 files changed, 577 insertions(+), 8 deletions(-)
