From 26fb0d552dc89cae2b76cc10ea87b889c4b32123 Mon Sep 17 00:00:00 2001 From: Vandita Kulkarni Date: Mon, 28 Sep 2020 16:38:34 +0530 Subject: drm/i915/dsi: Initiate frame request in cmd mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In TE Gate mode or TE NO_GATE mode on every flip we need to set the frame update request bit. After this bit is set transcoder hardware will automatically send the frame data to the panel in case of TE NO_GATE mode, where it sends after it receives the TE event in case of TE_GATE mode. Once the frame data is sent to the panel, we see the frame counter updating. v2: Use intel_de_read/write v3: remove the usage of private_flags v4: Use icl_dsi in func names if non static, fix code formatting issues. (Jani) v5: Send frame update request at the beginning of pipe_update_end, use crtc_state mode_flags (Ville) v6: Add platform and dsi checks (Ville) Acked-by: Ville Syrjälä Signed-off-by: Vandita Kulkarni Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20200928110834.15077-1-vandita.kulkarni@intel.com --- drivers/gpu/drm/i915/display/intel_dsi.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/drm/i915/display/intel_dsi.h') diff --git a/drivers/gpu/drm/i915/display/intel_dsi.h b/drivers/gpu/drm/i915/display/intel_dsi.h index 19f78a4022d3..625f2f1ae061 100644 --- a/drivers/gpu/drm/i915/display/intel_dsi.h +++ b/drivers/gpu/drm/i915/display/intel_dsi.h @@ -167,6 +167,7 @@ static inline u16 intel_dsi_encoder_ports(struct intel_encoder *encoder) /* icl_dsi.c */ void icl_dsi_init(struct drm_i915_private *dev_priv); +void icl_dsi_frame_update(struct intel_crtc_state *crtc_state); /* intel_dsi.c */ int intel_dsi_bitrate(const struct intel_dsi *intel_dsi); -- cgit v1.2.3
