From 549e2bfb54905c734aae77d2cdb809a7acaefeeb Mon Sep 17 00:00:00 2001 From: Chandra Konduru Date: Tue, 7 Apr 2015 15:28:38 -0700 Subject: [PATCH] drm/i915: Initialize skylake scalers Initializing scalers with supported values during crtc init. v2: -initialize single copy of min/max values (Matt) v3: -moved gen check to callsite (Matt) v4: -squashed planes begin with no scaler to here (me) v5: -updated init function with updated scaler state structure (Matt) Signed-off-by: Chandra Konduru Reviewed-by: Matt Roper Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_display.c | 32 ++++++++++++++++++++++++++++ drivers/gpu/drm/i915/intel_sprite.c | 1 + 2 files changed, 33 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index d98d5f239dd7..402fad0870ba 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -103,6 +103,8 @@ static void chv_prepare_pll(struct intel_crtc *crtc, const struct intel_crtc_state *pipe_config); static void intel_begin_crtc_commit(struct drm_crtc *crtc); static void intel_finish_crtc_commit(struct drm_crtc *crtc); +static void skl_init_scalers(struct drm_device *dev, struct intel_crtc *intel_crtc, + struct intel_crtc_state *crtc_state); static struct intel_encoder *intel_find_encoder(struct intel_connector *connector, int pipe) { @@ -12862,6 +12864,7 @@ static struct drm_plane *intel_primary_plane_create(struct drm_device *dev, primary->can_scale = false; primary->max_downscale = 1; + state->scaler_id = -1; primary->pipe = pipe; primary->plane = pipe; primary->check_plane = intel_check_primary_plane; @@ -13026,6 +13029,7 @@ static struct drm_plane *intel_cursor_plane_create(struct drm_device *dev, cursor->max_downscale = 1; cursor->pipe = pipe; cursor->plane = pipe; + state->scaler_id = -1; cursor->check_plane = intel_check_cursor_plane; cursor->commit_plane = intel_commit_cursor_plane; @@ -13052,6 +13056,24 @@ static struct drm_plane *intel_cursor_plane_create(struct drm_device *dev, return &cursor->base; } +static void skl_init_scalers(struct drm_device *dev, struct intel_crtc *intel_crtc, + struct intel_crtc_state *crtc_state) +{ + int i; + struct intel_scaler *intel_scaler; + struct intel_crtc_scaler_state *scaler_state = &crtc_state->scaler_state; + + for (i = 0; i < intel_crtc->num_scalers; i++) { + intel_scaler = &scaler_state->scalers[i]; + intel_scaler->in_use = 0; + intel_scaler->id = i; + + intel_scaler->mode = PS_SCALER_MODE_DYN; + } + + scaler_state->scaler_id = -1; +} + static void intel_crtc_init(struct drm_device *dev, int pipe) { struct drm_i915_private *dev_priv = dev->dev_private; @@ -13071,6 +13093,16 @@ static void intel_crtc_init(struct drm_device *dev, int pipe) intel_crtc_set_state(intel_crtc, crtc_state); crtc_state->base.crtc = &intel_crtc->base; + /* initialize shared scalers */ + if (INTEL_INFO(dev)->gen >= 9) { + if (pipe == PIPE_C) + intel_crtc->num_scalers = 1; + else + intel_crtc->num_scalers = SKL_NUM_SCALERS; + + skl_init_scalers(dev, intel_crtc, crtc_state); + } + primary = intel_primary_plane_create(dev, pipe); if (!primary) goto fail; diff --git a/drivers/gpu/drm/i915/intel_sprite.c b/drivers/gpu/drm/i915/intel_sprite.c index 7d1a5b86d06c..6d4e1ea4219f 100644 --- a/drivers/gpu/drm/i915/intel_sprite.c +++ b/drivers/gpu/drm/i915/intel_sprite.c @@ -1294,6 +1294,7 @@ intel_plane_init(struct drm_device *dev, enum pipe pipe, int plane) intel_plane->max_downscale = 1; intel_plane->update_plane = skl_update_plane; intel_plane->disable_plane = skl_disable_plane; + state->scaler_id = -1; plane_formats = skl_plane_formats; num_plane_formats = ARRAY_SIZE(skl_plane_formats); -- 2.20.1
