From 412b1e463ec3200970218d7c23bd4310da55b894 Mon Sep 17 00:00:00 2001 From: Yongqiang Niu Date: Thu, 29 Aug 2019 22:50:44 +0800 Subject: [PATCH] drm/mediatek: add ovl0/ovl_2l0 usecase This patch add ovl0/ovl_2l0 usecase in ovl->ovl_2l0 direct link usecase: 1. the crtc support layer number will 4+2 2. ovl_2l0 background color input select ovl0 when crtc init and disable it when crtc finish 3. config ovl_2l0 layer, if crtc config layer number is bigger than ovl0 support layers(max is 4) Signed-off-by: Yongqiang Niu Signed-off-by: CK Hu --- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 37 +++++++++++++++++++++++-- 1 file changed, 34 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/mediatek/mtk_drm_crtc.c b/drivers/gpu/drm/mediatek/mtk_drm_crtc.c index 34a731755791..b841d3706d8b 100644 --- a/drivers/gpu/drm/mediatek/mtk_drm_crtc.c +++ b/drivers/gpu/drm/mediatek/mtk_drm_crtc.c @@ -272,6 +272,9 @@ static int mtk_crtc_ddp_hw_init(struct mtk_drm_crtc *mtk_crtc) for (i = 0; i < mtk_crtc->ddp_comp_nr; i++) { struct mtk_ddp_comp *comp = mtk_crtc->ddp_comp[i]; + if (i == 1) + mtk_ddp_comp_bgclr_in_on(comp); + mtk_ddp_comp_config(comp, width, height, vrefresh, bpc); mtk_ddp_comp_start(comp); } @@ -280,9 +283,18 @@ static int mtk_crtc_ddp_hw_init(struct mtk_drm_crtc *mtk_crtc) for (i = 0; i < mtk_crtc->layer_nr; i++) { struct drm_plane *plane = &mtk_crtc->planes[i]; struct mtk_plane_state *plane_state; + struct mtk_ddp_comp *comp = mtk_crtc->ddp_comp[0]; + unsigned int comp_layer_nr = mtk_ddp_comp_layer_nr(comp); + unsigned int local_layer; plane_state = to_mtk_plane_state(plane->state); - mtk_ddp_comp_layer_config(mtk_crtc->ddp_comp[0], i, + + if (i >= comp_layer_nr) { + comp = mtk_crtc->ddp_comp[1]; + local_layer = i - comp_layer_nr; + } else + local_layer = i; + mtk_ddp_comp_layer_config(comp, local_layer, plane_state); } @@ -301,8 +313,12 @@ static void mtk_crtc_ddp_hw_fini(struct mtk_drm_crtc *mtk_crtc) int i; DRM_DEBUG_DRIVER("%s\n", __func__); - for (i = 0; i < mtk_crtc->ddp_comp_nr; i++) + for (i = 0; i < mtk_crtc->ddp_comp_nr; i++) { mtk_ddp_comp_stop(mtk_crtc->ddp_comp[i]); + if (i == 1) + mtk_ddp_comp_bgclr_in_off(mtk_crtc->ddp_comp[i]); + } + for (i = 0; i < mtk_crtc->ddp_comp_nr; i++) mtk_disp_mutex_remove_comp(mtk_crtc->mutex, mtk_crtc->ddp_comp[i]->id); @@ -327,6 +343,8 @@ static void mtk_crtc_ddp_config(struct drm_crtc *crtc) struct mtk_crtc_state *state = to_mtk_crtc_state(mtk_crtc->base.state); struct mtk_ddp_comp *comp = mtk_crtc->ddp_comp[0]; unsigned int i; + unsigned int comp_layer_nr = mtk_ddp_comp_layer_nr(comp); + unsigned int local_layer; /* * TODO: instead of updating the registers here, we should prepare @@ -349,7 +367,14 @@ static void mtk_crtc_ddp_config(struct drm_crtc *crtc) plane_state = to_mtk_plane_state(plane->state); if (plane_state->pending.config) { - mtk_ddp_comp_layer_config(comp, i, plane_state); + if (i >= comp_layer_nr) { + comp = mtk_crtc->ddp_comp[1]; + local_layer = i - comp_layer_nr; + } else + local_layer = i; + + mtk_ddp_comp_layer_config(comp, local_layer, + plane_state); plane_state->pending.config = false; } } @@ -582,6 +607,12 @@ int mtk_drm_crtc_create(struct drm_device *drm_dev, } mtk_crtc->layer_nr = mtk_ddp_comp_layer_nr(mtk_crtc->ddp_comp[0]); + if (mtk_crtc->ddp_comp_nr > 1) { + struct mtk_ddp_comp *comp = mtk_crtc->ddp_comp[1]; + + if (comp->funcs->bgclr_in_on) + mtk_crtc->layer_nr += mtk_ddp_comp_layer_nr(comp); + } mtk_crtc->planes = devm_kcalloc(dev, mtk_crtc->layer_nr, sizeof(struct drm_plane), GFP_KERNEL); -- 2.30.2
