It should be easier now that you can focus on enabling the checks for one feature or platform, and if needed, one patch, at a time. :) BR, Jani.

In this patch series, added state checker to validate gamma (8BIT and 10BIT).This reads hardware state, and compares the originally requested state(s/w) to the state read from the hardware. This is done for legacy, ilk, glk and their variant platforms. Rest of the platforms will be enabled on top of this later. 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 v10: -Dropped multi-seg gamma mode [Jani] -Enabled basic infrastructure only [Jani] -Minor fixes [Jani] Swati Sharma (8): 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 ilk_read_luts() drm/i915/display: Extract glk_read_luts() FOR_TESTING_ONLY: Print rgb values of hw and sw blobs drivers/gpu/drm/i915/display/intel_color.c | 284 ++++++++++++++++++++++++++- 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 | 9 + 4 files changed, 331 insertions(+), 3 deletions(-)
