From ee36c7c0c83767c6e541a4c77bd10a7f788a5db0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Roberto=20de=20Souza?= Date: Sun, 22 Dec 2019 17:06:48 -0800 Subject: [PATCH] drm/i915/display: Share intel_connector_needs_modeset() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit intel_connector_needs_modeset() will be used outside of intel_display.c in a future patch so it would only be necessary to remove the state and add the prototype to the header file. But while at it, I simplified the arguments and moved it to a better place intel_atomic.c. No behavior changes intended here. v3: - removed digital from exported version of intel_connector_needs_modeset - rollback connector to drm type v4: - Renamed new_connector_state to new_conn_state - Going back to drm_connector_state in intel_encoders_update_prepare/complete as we also have intel_tv_connector_state Reviewed-by: Ville Syrjälä Cc: Ville Syrjälä Cc: Lucas De Marchi Signed-off-by: José Roberto de Souza Link: https://patchwork.freedesktop.org/patch/msgid/20191223010654.67037-1-jose.souza@intel.com --- drivers/gpu/drm/i915/display/intel_atomic.c | 18 ++++++++ drivers/gpu/drm/i915/display/intel_atomic.h | 2 + drivers/gpu/drm/i915/display/intel_display.c | 45 ++++++-------------- 3 files changed, 34 insertions(+), 31 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_atomic.c b/drivers/gpu/drm/i915/display/intel_atomic.c index fd0026fc3618..b7dda18b6f29 100644 --- a/drivers/gpu/drm/i915/display/intel_atomic.c +++ b/drivers/gpu/drm/i915/display/intel_atomic.c @@ -174,6 +174,24 @@ intel_digital_connector_duplicate_state(struct drm_connector *connector) return &state->base; } +/** + * intel_connector_needs_modeset - check if connector needs a modeset + */ +bool +intel_connector_needs_modeset(struct intel_atomic_state *state, + struct drm_connector *connector) +{ + const struct drm_connector_state *old_conn_state, *new_conn_state; + + old_conn_state = drm_atomic_get_old_connector_state(&state->base, connector); + new_conn_state = drm_atomic_get_new_connector_state(&state->base, connector); + + return old_conn_state->crtc != new_conn_state->crtc || + (new_conn_state->crtc && + drm_atomic_crtc_needs_modeset(drm_atomic_get_new_crtc_state(&state->base, + new_conn_state->crtc))); +} + /** * intel_crtc_duplicate_state - duplicate crtc state * @crtc: drm crtc diff --git a/drivers/gpu/drm/i915/display/intel_atomic.h b/drivers/gpu/drm/i915/display/intel_atomic.h index 7b49623419ba..a7d1a8576c48 100644 --- a/drivers/gpu/drm/i915/display/intel_atomic.h +++ b/drivers/gpu/drm/i915/display/intel_atomic.h @@ -32,6 +32,8 @@ int intel_digital_connector_atomic_check(struct drm_connector *conn, struct drm_atomic_state *state); struct drm_connector_state * intel_digital_connector_duplicate_state(struct drm_connector *connector); +bool intel_connector_needs_modeset(struct intel_atomic_state *state, + struct drm_connector *connector); struct drm_crtc_state *intel_crtc_duplicate_state(struct drm_crtc *crtc); void intel_crtc_destroy_state(struct drm_crtc *crtc, diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 6fcf3d8bddc3..16e4cf1eade2 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -6417,39 +6417,23 @@ intel_connector_primary_encoder(struct intel_connector *connector) return encoder; } -static bool -intel_connector_needs_modeset(struct intel_atomic_state *state, - const struct drm_connector_state *old_conn_state, - const struct drm_connector_state *new_conn_state) -{ - struct intel_crtc *old_crtc = old_conn_state->crtc ?
