From db9cd76d099a0e4337d30e22c89fe019332bcec1 Mon Sep 17 00:00:00 2001 From: "Lowry Li (Arm Technology China)" Date: Tue, 12 Nov 2019 11:10:28 +0000 Subject: [PATCH] drm/komeda: Adds gamma and color-transform support for DOU-IPS Adds gamma and color-transform support for DOU-IPS. Adds two caps members fgamma_coeffs and ctm_coeffs to komeda_improc_state. If color management changed, set gamma and color-transform accordingly. v5: Rebase with drm-misc-next Signed-off-by: Lowry Li (Arm Technology China) Signed-off-by: james qian wang (Arm Technology China) Reviewed-by: Mihail Atanassov Link: https://patchwork.freedesktop.org/patch/msgid/20191112110927.20931-5-james.qian.wang@arm.com --- .../arm/display/komeda/d71/d71_component.c | 20 +++++++++++++++++++ .../gpu/drm/arm/display/komeda/komeda_crtc.c | 2 ++ .../drm/arm/display/komeda/komeda_pipeline.h | 3 +++ .../display/komeda/komeda_pipeline_state.c | 6 ++++++ 4 files changed, 31 insertions(+) diff --git a/drivers/gpu/drm/arm/display/komeda/d71/d71_component.c b/drivers/gpu/drm/arm/display/komeda/d71/d71_component.c index f0ba26e282c3..b6517c46e670 100644 --- a/drivers/gpu/drm/arm/display/komeda/d71/d71_component.c +++ b/drivers/gpu/drm/arm/display/komeda/d71/d71_component.c @@ -1044,7 +1044,9 @@ static int d71_merger_init(struct d71_dev *d71, static void d71_improc_update(struct komeda_component *c, struct komeda_component_state *state) { + struct drm_crtc_state *crtc_st = state->crtc->state; struct komeda_improc_state *st = to_improc_st(state); + struct d71_pipeline *pipe = to_d71_pipeline(c->pipeline); u32 __iomem *reg = c->reg; u32 index, mask = 0, ctrl = 0; @@ -1055,6 +1057,24 @@ static void d71_improc_update(struct komeda_component *c, malidp_write32(reg, BLK_SIZE, HV_SIZE(st->hsize, st->vsize)); malidp_write32(reg, IPS_DEPTH, st->color_depth); + if (crtc_st->color_mgmt_changed) { + mask |= IPS_CTRL_FT | IPS_CTRL_RGB; + + if (crtc_st->gamma_lut) { + malidp_write_group(pipe->dou_ft_coeff_addr, FT_COEFF0, + KOMEDA_N_GAMMA_COEFFS, + st->fgamma_coeffs); + ctrl |= IPS_CTRL_FT; /* enable gamma */ + } + + if (crtc_st->ctm) { + malidp_write_group(reg, IPS_RGB_RGB_COEFF0, + KOMEDA_N_CTM_COEFFS, + st->ctm_coeffs); + ctrl |= IPS_CTRL_RGB; /* enable gamut */ + } + } + mask |= IPS_CTRL_YUV | IPS_CTRL_CHD422 | IPS_CTRL_CHD420; /* config color format */ diff --git a/drivers/gpu/drm/arm/display/komeda/komeda_crtc.c b/drivers/gpu/drm/arm/display/komeda/komeda_crtc.c index 252015210fbc..1c452ea75999 100644 --- a/drivers/gpu/drm/arm/display/komeda/komeda_crtc.c +++ b/drivers/gpu/drm/arm/display/komeda/komeda_crtc.c @@ -617,6 +617,8 @@ static int komeda_crtc_add(struct komeda_kms_dev *kms, crtc->port = kcrtc->master->of_output_port; + drm_crtc_enable_color_mgmt(crtc, 0, true, KOMEDA_COLOR_LUT_SIZE); + return err; } diff --git a/drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h b/drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h index bd6ca7c87037..ac8725e24853 100644 --- a/drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h +++ b/drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h @@ -11,6 +11,7 @@ #include #include #include "malidp_utils.h" +#include "komeda_color_mgmt.h" #define KOMEDA_MAX_PIPELINES 2 #define KOMEDA_PIPELINE_MAX_LAYERS 4 @@ -327,6 +328,8 @@ struct komeda_improc_state { struct komeda_component_state base; u8 color_format, color_depth; u16 hsize, vsize; + u32 fgamma_coeffs[KOMEDA_N_GAMMA_COEFFS]; + u32 ctm_coeffs[KOMEDA_N_CTM_COEFFS]; }; /* display timing controller */ diff --git a/drivers/gpu/drm/arm/display/komeda/komeda_pipeline_state.c b/drivers/gpu/drm/arm/display/komeda/komeda_pipeline_state.c index 42bdc63dcffa..0930234abb9d 100644 --- a/drivers/gpu/drm/arm/display/komeda/komeda_pipeline_state.c +++ b/drivers/gpu/drm/arm/display/komeda/komeda_pipeline_state.c @@ -802,6 +802,12 @@ komeda_improc_validate(struct komeda_improc *improc, st->color_format = BIT(__ffs(avail_formats)); } + if (kcrtc_st->base.color_mgmt_changed) { + drm_lut_to_fgamma_coeffs(kcrtc_st->base.gamma_lut, + st->fgamma_coeffs); + drm_ctm_to_coeffs(kcrtc_st->base.ctm, st->ctm_coeffs); + } + komeda_component_add_input(&st->base, &dflow->input, 0); komeda_component_set_output(&dflow->input, &improc->base, 0); -- 2.20.1
