Namely, change the pixel clock math to consider YUV420 and modify the MVID programming to consider YUV420. Changes in v2: - Move configuration control programming to a different commit - Slight code simplification - Add VSC SDP check when doing mode_pclk_khz division in dp_bridge_mode_valid Signed-off-by: Paloma Arellano Reviewed-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/dp/dp_catalog.c | 5 ++++- drivers/gpu/drm/msm/dp/dp_catalog.h | 2 +- drivers/gpu/drm/msm/dp/dp_ctrl.c | 9 ++++++--- drivers/gpu/drm/msm/dp/dp_display.c | 4 ++++ 4 files changed, 15 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/msm/dp/dp_catalog.c b/drivers/gpu/drm/msm/dp/dp_catalog.c index 5142aeb705a44..5d84c089e520a 100644 --- a/drivers/gpu/drm/msm/dp/dp_catalog.c +++ b/drivers/gpu/drm/msm/dp/dp_catalog.c @@ -442,7 +442,7 @@ void dp_catalog_ctrl_config_misc(struct dp_catalog *dp_catalog, void dp_catalog_ctrl_config_msa(struct dp_catalog *dp_catalog, u32 rate, u32 stream_rate_khz, - bool fixed_nvid) + bool fixed_nvid, bool is_ycbcr_420) { u32 pixel_m, pixel_n; u32 mvid, nvid, pixel_div = 0, dispcc_input_rate; @@ -485,6 +485,9 @@ void dp_catalog_ctrl_config_msa(struct dp_catalog *dp_catalog, nvid = temp; } + if (is_ycbcr_420) + mvid /= 2; + if (link_rate_hbr2 == rate) nvid *= 2; diff --git a/drivers/gpu/drm/msm/dp/dp_catalog.h b/drivers/gpu/drm/msm/dp/dp_catalog.h index 38786e855b51a..6cb5e2a243de2 100644 --- a/drivers/gpu/drm/msm/dp/dp_catalog.h +++ b/drivers/gpu/drm/msm/dp/dp_catalog.h @@ -96,7 +96,7 @@ void dp_catalog_ctrl_mainlink_ctrl(struct dp_catalog *dp_catalog, bool enable); void dp_catalog_ctrl_psr_mainlink_enable(struct dp_catalog *dp_catalog, bool enable); void dp_catalog_ctrl_config_misc(struct dp_catalog *dp_catalog, u32 cc, u32 tb); void dp_catalog_ctrl_config_msa(struct dp_catalog *dp_catalog, u32 rate, - u32 stream_rate_khz, bool fixed_nvid); + u32 stream_rate_khz, bool fixed_nvid, bool is_ycbcr_420); int dp_catalog_ctrl_set_pattern_state_bit(struct dp_catalog *dp_catalog, u32 pattern); u32 dp_catalog_hw_revision(const struct dp_catalog *dp_catalog); void dp_catalog_ctrl_reset(struct dp_catalog *dp_catalog); diff --git a/drivers/gpu/drm/msm/dp/dp_ctrl.c b/drivers/gpu/drm/msm/dp/dp_ctrl.c index 6692d81adb195..bffb7bac2c2c8 100644 --- a/drivers/gpu/drm/msm/dp/dp_ctrl.c +++ b/drivers/gpu/drm/msm/dp/dp_ctrl.c @@ -955,7 +955,7 @@ static void dp_ctrl_calc_tu_parameters(struct dp_ctrl_private *ctrl, in.hporch = drm_mode->htotal - drm_mode->hdisplay; in.nlanes = ctrl->link->link_params.num_lanes; in.bpp = ctrl->panel->dp_mode.bpp; - in.pixel_enc = 444; + in.pixel_enc = ctrl->panel->dp_mode.out_fmt_is_yuv_420 ? 420 : 444; in.dsc_en = 0; in.async_en = 0; in.fec_en = 0; @@ -1761,6 +1761,8 @@ int dp_ctrl_on_link(struct dp_ctrl *dp_ctrl) ctrl->link->link_params.rate = rate; ctrl->link->link_params.num_lanes = ctrl->panel->link_info.num_lanes; + if (ctrl->panel->dp_mode.out_fmt_is_yuv_420) + pixel_rate >>= 1; } drm_dbg_dp(ctrl->drm_dev, "rate=%d, num_lanes=%d, pixel_rate=%lu\n", @@ -1876,7 +1878,7 @@ int dp_ctrl_on_stream(struct dp_ctrl *dp_ctrl, bool force_link_train) pixel_rate = pixel_rate_orig = ctrl->panel->dp_mode.drm_mode.clock; - if (dp_ctrl->wide_bus_en) + if (dp_ctrl->wide_bus_en || ctrl->panel->dp_mode.out_fmt_is_yuv_420) pixel_rate >>= 1; drm_dbg_dp(ctrl->drm_dev, "rate=%d, num_lanes=%d, pixel_rate=%lu\n", @@ -1915,7 +1917,8 @@ int dp_ctrl_on_stream(struct dp_ctrl *dp_ctrl, bool force_link_train) dp_catalog_ctrl_config_msa(ctrl->catalog, ctrl->link->link_params.rate, - pixel_rate_orig, dp_ctrl_use_fixed_nvid(ctrl)); + pixel_rate_orig, dp_ctrl_use_fixed_nvid(ctrl), + ctrl->panel->dp_mode.out_fmt_is_yuv_420); dp_ctrl_setup_tr_unit(ctrl); diff --git a/drivers/gpu/drm/msm/dp/dp_display.c b/drivers/gpu/drm/msm/dp/dp_display.c index 4b1b79b74bc72..3b7c3a7fd4993 100644 --- a/drivers/gpu/drm/msm/dp/dp_display.c +++ b/drivers/gpu/drm/msm/dp/dp_display.c @@ -934,6 +934,10 @@ enum drm_mode_status dp_bridge_mode_valid(struct drm_bridge *bridge, dp_display = container_of(dp, struct dp_display_private, dp_display); link_info = &dp_display->panel->link_info; + if (drm_mode_is_420_only(&dp->connector->display_info, mode) && + dp_display->panel->vsc_sdp_supported) + mode_pclk_khz /= 2; + mode_bpp = dp->connector->display_info.bpc * num_components; if (!mode_bpp) mode_bpp = default_bpp;
