In addition, add support for setting and getting the values for solid_fill. solid_fill holds data for supporting solid fill planes. The property accepts an RGB323232 value and the driver data is formatted as such: struct drm_solid_fill { u32 r; u32 g; u32 b; }; To enable solid fill planes, userspace must assigned solid_fill to a property blob containing the following information: struct drm_solid_fill_info { u8 version; u32 r, g, b; }; Changes in V2: - Changed solid_fill property to a property blob (Simon, Dmitry) - Added drm_solid_fill struct (Simon) - Added drm_solid_fill_info struct (Simon) Signed-off-by: Jessica Zhang --- drivers/gpu/drm/drm_atomic_state_helper.c | 9 ++++ drivers/gpu/drm/drm_atomic_uapi.c | 59 +++++++++++++++++++++++ drivers/gpu/drm/drm_blend.c | 17 +++++++ include/drm/drm_blend.h | 1 + include/drm/drm_plane.h | 43 +++++++++++++++++ 5 files changed, 129 insertions(+) diff --git a/drivers/gpu/drm/drm_atomic_state_helper.c b/drivers/gpu/drm/drm_atomic_state_helper.c index dfb57217253b..c96fd1f2ad99 100644 --- a/drivers/gpu/drm/drm_atomic_state_helper.c +++ b/drivers/gpu/drm/drm_atomic_state_helper.c @@ -253,6 +253,11 @@ void __drm_atomic_helper_plane_state_reset(struct drm_plane_state *plane_state, plane_state->alpha = DRM_BLEND_ALPHA_OPAQUE; plane_state->pixel_blend_mode = DRM_MODE_BLEND_PREMULTI; + if (plane_state->solid_fill_blob) { + drm_property_blob_put(plane_state->solid_fill_blob); + plane_state->solid_fill_blob = NULL; + } + if (plane->color_encoding_property) { if (!drm_object_property_get_default_value(&plane->base, plane->color_encoding_property, @@ -335,6 +340,9 @@ void __drm_atomic_helper_plane_duplicate_state(struct drm_plane *plane, if (state->fb) drm_framebuffer_get(state->fb); + if (state->solid_fill_blob) + drm_property_blob_get(state->solid_fill_blob); + state->fence = NULL; state->commit = NULL; state->fb_damage_clips = NULL; @@ -384,6 +392,7 @@ void __drm_atomic_helper_plane_destroy_state(struct drm_plane_state *state) drm_crtc_commit_put(state->commit); drm_property_blob_put(state->fb_damage_clips); + drm_property_blob_put(state->solid_fill_blob); } EXPORT_SYMBOL(__drm_atomic_helper_plane_destroy_state); diff --git a/drivers/gpu/drm/drm_atomic_uapi.c b/drivers/gpu/drm/drm_atomic_uapi.c index c06d0639d552..8a1d2fb7a757 100644 --- a/drivers/gpu/drm/drm_atomic_uapi.c +++ b/drivers/gpu/drm/drm_atomic_uapi.c @@ -316,6 +316,55 @@ drm_atomic_set_crtc_for_connector(struct drm_connector_state *conn_state, } EXPORT_SYMBOL(drm_atomic_set_crtc_for_connector); +static void drm_atomic_convert_solid_fill_info(struct drm_solid_fill *out, + struct drm_solid_fill_info *in) +{ + out->r = in->r; + out->g = in->g; + out->b = in->b; +} + +static int drm_atomic_set_solid_fill_prop(struct drm_plane_state *state, + struct drm_property_blob *blob) +{ + int ret = 0; + int blob_version; + + if (blob == state->solid_fill_blob) + return 0; + + drm_property_blob_put(state->solid_fill_blob); + state->solid_fill_blob = NULL; + + memset(&state->solid_fill, 0, sizeof(state->solid_fill)); + + if (blob) { + if (blob->length != sizeof(struct drm_solid_fill_info)) { + drm_dbg_atomic(state->plane->dev, + "[PLANE:%d:%s] bad solid fill blob length: %zu\n", + state->plane->base.id, state->plane->name, + blob->length); + return -EINVAL; + } + + blob_version = ((struct drm_solid_fill_info *)blob->data)->version; + + /* Append with more versions if necessary */ + if (blob_version == 1) { + drm_atomic_convert_solid_fill_info(&state->solid_fill, blob->data); + } else { + drm_dbg_atomic(state->plane->dev, + "[PLANE:%d:%s] failed to set solid fill (ret=%d)\n", + state->plane->base.id, state->plane->name, + ret); + return -EINVAL; + } + state->solid_fill_blob = drm_property_blob_get(blob); + } + + return ret; +} + static void set_out_fence_for_crtc(struct drm_atomic_state *state, struct drm_crtc *crtc, s32 __user *fence_ptr) { @@ -544,6 +593,13 @@ static int drm_atomic_plane_set_property(struct drm_plane *plane, state->src_w = val; } else if (property == config->prop_src_h) { state->src_h = val; + } else if (property == plane->solid_fill_property) { + struct drm_property_blob *solid_fill = drm_property_lookup_blob(dev, val); + + ret = drm_atomic_set_solid_fill_prop(state, solid_fill); + drm_property_blob_put(solid_fill); + + return ret; } else if (property == plane->alpha_property) { state->alpha = val; } else if (property == plane->blend_mode_property) { @@ -616,6 +672,9 @@ drm_atomic_plane_get_property(struct drm_plane *plane, *val = state->src_w; } else if (property == config->prop_src_h) { *val = state->src_h; + } else if (property == plane->solid_fill_property) { + *val = state->solid_fill_blob ?
