[PATCH 0/4] fix broken state checker and enable state checker for icl+

[Swati Sharma]

In this patch series, basically added 3 patches
 1. Fixing broken state-checker during boot since legacy platforms
    i.e. platforms for which state checker was already enabled
 2. Moving gamma_enable checks in bit_precision func() to platform
    specific func()
 3. Enabling state checker for ICL and TGL

  [v2] drm/i915/color: fix broken gamma state-checker during boot
  drm/i915/color: move check of gamma_enable to specific func/platform
  [v5] drm/i915/color: Extract icl_read_luts()
  FOR_TESTING_ONLY: Print rgb values of hw and sw blobs

[PATCH 1/4] [v2] drm/i915/color: fix broken gamma state-checker during boot

[Swati Sharma]

Premature gamma lut prepration and loading which was getting
reflected in first modeset causing different colors on
screen during boot.

Issue: In BIOS, gamma is disabled by default. However, legacy read_luts()
was setting crtc_state->base.gamma_lut and gamma_lut was programmed
with junk values which led to visual artifacts (different
colored screens instead of usual black during boot).

Fix: Calling read_luts() only when gamma is enabled which will happen
after first modeset.

This fix is independent from the revert 1b8588741fdc ("Revert
"drm/i915/color: Extract icl_read_luts()"") and should fix different colors
on screen in legacy platforms too.

-Added gamma_enable checks inside read_luts() [Ville/Jani N]
-Corrected gamma enable check for CHV [Ville]

[PATCH 2/4] drm/i915/color: move check of gamma_enable to specific func/platform

[Swati Sharma]

Moved common code to check gamma_enable to specific funcs per platform
in bit_precision func. icl doesn't support that and chv has separate
enable knob for CGM LUT.

[PATCH 3/4] [v5] drm/i915/color: Extract icl_read_luts()

[Swati Sharma]

For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.

This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.

Major change done-removal of readouts of coarse and fine segments
because PAL_PREC_DATA register isn't giving propoer values.
State checker limited only to "fine segment"

v2: -readout code for multisegmented gamma has to come
     up with some intermediate entries that aren't preserved
     in hardware (Jani N)
    -linear interpolation (Ville)
    -moved common code to check gamma_enable to specific funcs,
     since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
    -used single lut [Jani N]
    -improved and more readable for loops [Jani N]
    -read values directly to actual locations and then fill gaps [Jani N]
    -moved cleaning to patch 1 [Jani N]
    -renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
     make it similar to icl_load_luts()
    -renamed icl_compute_interpolated_gamma_blob() to
     icl_compute_interpolated_gamma_lut_values() more sensible, I guess
v4: -removed interpolated func for creating gamma lut values
    -removed readouts of fine and coarse segments, failure to read PAL_PREC_DATA
     correctly
v5: -added gamma_enable check inside read_luts()

I'd simply make this something like:

if (crtc_state->cgm_mode & CGM_PIPE_MODE_GAMMA) {
	crtc_state->base.gamma_lut = chv_read_cgm_lut(crtc_state);
} else {
	i965_read_luts(crtc_state);
}

We should check
        if ((crtc_state->csc_mode & CSC_POSITION_BEFORE_GAMMA) == 0)
	                return;

here so we don't read the hw degamma into the state gmama_lut.

Again could simplify to just:

if (crtc_state->cgm_mode & CGM_PIPE_MODE_GAMMA)
	return 10;
else
	return i9xx_gamma_precision(crtc_state);
