[PATCH RFC v5 00/10] Support for Solid Fill Planes
Some drivers support hardware that have optimizations for solid fill planes. This series aims to expose these capabilities to userspace as some compositors have a solid fill flag (ex. SOLID_COLOR in the Android hardware composer HAL) that can be set by apps like the Android Gears app. In order to expose this capability to userspace, this series will: - Introduce solid_fill and pixel_source properties to allow userspace to toggle between FB and solid fill sources - Loosen NULL FB checks within the DRM atomic commit callstack to allow for NULL FB when solid fill is enabled. - Add NULL FB checks in methods where FB was previously assumed to be non-NULL - Have MSM DPU driver use drm_plane_state.solid_fill instead of dpu_plane_state.color_fill Note: The solid fill planes feature depends on both the solid_fill *and* pixel_source properties. To use this feature, userspace can set the solid_fill property to a blob containing the appropriate version number and solid fill color (in RGB323232 format) and and setting the pixel_source property to DRM_PLANE_PIXEL_SOURCE_COLOR. This will disable memory fetch and the resulting plane will display the color specified by the solid_fill blob. Currently, there's only one version of the solid_fill blob property. However if other drivers want to support a similar feature, but require more than just the solid fill color, they can extend this feature by creating additional versions of the drm_solid_fill struct. This 2 property approach was chosen because passing in a special 1x1 FB with the necessary color information would have unecessary overhead that does not reflect the behavior of the solid fill feature. In addition, assigning the solid fill blob to FB_ID would require loosening some core drm_property checks that might cause unwanted side effects elsewhere. --- Changes in v5: - Added support for PIXEL_SOURCE_NONE (Sebastian) - Added WARN_ON() in drm_plane_has_visible_data() if pixel_source isn't set (Dmitry) - Added debugfs support for both properties (Dmitry) - Corrected u32 to u8 conversion (Pekka) - Moved drm_solid_fill_info struct and related documentation to include/uapi (Pekka) - Changed drm_solid_fill_info.version to __u32 for data alignment (Pekka) - Added more detailed UAPI and kernel documentation (Pekka) - Reordered patch series so that the pixel_source property is introduced before solid_fill (Dmitry) - Fixed inconsistent ABGR/RGBA format declaration (Pekka) - Reset pixel_source to FB in drm_mode_setplane() (Dmitry) - Rename supported_sources to extra_sources (Dmitry) - Only destroy old solid_fill blob state if new state is valid (Pekka) - Link to v4: https://lore.kernel.org/r/20230404-solid-fill-v4-0-f4ec0caa7...@quicinc.com Changes in v4: - Rebased onto latest kernel - Reworded cover letter for clarity (Dmitry) - Reworded commit messages for clarity - Split existing changes into smaller commits - Added pixel_source enum property (Dmitry, Pekka, Ville) - Updated drm-kms comment docs with pixel_source and solid_fill properties (Dmitry) - Inlined drm_atomic_convert_solid_fill_info() (Dmitry) - Passed in plane state alpha value to _dpu_plane_color_fill_pipe() - Link to v3: https://lore.kernel.org/r/20230104234036.636-1-quic_jessz...@quicinc.com Changes in v3: - Fixed some logic errors in atomic checks (Dmitry) - Introduced drm_plane_has_visible_data() and drm_atomic_check_fb() helper methods (Dmitry) - Fixed typo in drm_solid_fill struct documentation - Created drm_plane_has_visible_data() helper and corrected CRTC and FB NULL-check logic (Dmitry) - Merged `if (fb)` blocks in drm_atomic_plane_check() and abstracted them into helper method (Dmitry) - Inverted `if (solid_fill_enabled) else if (fb)` check order (Dmitry) - Fixed indentation (Dmitry) Changes in v2: - Dropped SOLID_FILL_FORMAT property (Simon) - Switched to implementing solid_fill property as a blob (Simon, Dmitry) - Added drm_solid_fill and drm_solid_fill_info structs (Simon) - Changed to checks for if solid_fill_blob is set (Dmitry) - Abstracted (plane_state && !solid_fill_blob) checks to helper method (Dmitry) - Removed DPU_PLANE_COLOR_FILL_FLAG - Fixed whitespace and indentation issues (Dmitry) - Changed to checks for if solid_fill_blob is set (Dmitry) - Abstracted (plane_state && !solid_fill_blob) checks to helper method (Dmitry) - Fixed dropped 'const' warning - Added helper to convert color fill to BGR888 (Rob) - Fixed indentation issue (Dmitry) - Added support for solid fill on planes of varying sizes --- Jessica Zhang (10): drm: Introduce pixel_source DRM plane property drm: Introduce solid fill DRM plane property drm: Add solid fill pixel source drm/atomic: Add pixel source to plane state dump drm/atomic: Add solid fill data to plane state dump drm/atomic: Move framebuffer checks to helper drm/atomic: Loosen FB atomic checks drm/msm/dpu: Allow NULL FBs in atomic commit drm/msm/dpu: Use DRM solid_

Loosen the requirements for atomic and legacy commit so that, in cases where pixel_source != FB, the commit can still go through. This includes adding framebuffer NULL checks in other areas to account for FB being NULL when non-FB pixel sources are enabled. To disable a plane, the pixel_source must be NONE or the FB must be NULL if pixel_source == FB.

To enable solid fill planes, userspace must assign a property blob to the "solid_fill" plane property containing the following information: struct drm_mode_solid_fill { u32 version; u32 r, g, b; }; Signed-off-by: Jessica Zhang --- drivers/gpu/drm/drm_atomic_state_helper.c | 9 + drivers/gpu/drm/drm_atomic_uapi.c | 55 +++ drivers/gpu/drm/drm_blend.c | 30 + include/drm/drm_blend.h | 1 + include/drm/drm_plane.h | 35 include/uapi/drm/drm_mode.h | 24 ++ 6 files changed, 154 insertions(+) diff --git a/drivers/gpu/drm/drm_atomic_state_helper.c b/drivers/gpu/drm/drm_atomic_state_helper.c index 01638c51ce0a..86fb876efbe6 100644 --- a/drivers/gpu/drm/drm_atomic_state_helper.c +++ b/drivers/gpu/drm/drm_atomic_state_helper.c @@ -254,6 +254,11 @@ void __drm_atomic_helper_plane_state_reset(struct drm_plane_state *plane_state, plane_state->pixel_blend_mode = DRM_MODE_BLEND_PREMULTI; plane_state->pixel_source = DRM_PLANE_PIXEL_SOURCE_FB; + 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, @@ -336,6 +341,9 @@ 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; @@ -385,6 +393,7 @@ 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 454f980e16c9..039686c78c2a 100644 --- a/drivers/gpu/drm/drm_atomic_uapi.c +++ b/drivers/gpu/drm/drm_atomic_uapi.c @@ -316,6 +316,51 @@ drm_atomic_set_crtc_for_connector(struct drm_connector_state *conn_state, } EXPORT_SYMBOL(drm_atomic_set_crtc_for_connector); +static int drm_atomic_set_solid_fill_prop(struct drm_plane_state *state, + struct drm_property_blob *blob) +{ + int blob_version; + + if (blob == state->solid_fill_blob) + return 0; + + if (blob) { + struct drm_mode_solid_fill *user_info = (struct drm_mode_solid_fill *)blob->data; + + if (blob->length != sizeof(struct drm_mode_solid_fill)) { + 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 = user_info->version; + + /* Add more versions if necessary */ + if (blob_version == 1) { + state->solid_fill.r = user_info->r; + state->solid_fill.g = user_info->g; + state->solid_fill.b = user_info->b; + } else { + drm_dbg_atomic(state->plane->dev, + "[PLANE:%d:%s] unsupported solid fill version (version=%d)\n", + state->plane->base.id, state->plane->name, + blob_version); + return -EINVAL; + } + } + + drm_property_blob_put(state->solid_fill_blob); + + if (blob) + state->solid_fill_blob = drm_property_blob_get(blob); + else + state->solid_fill_blob = NULL; + + return 0; +} + static void set_out_fence_for_crtc(struct drm_atomic_state *state, struct drm_crtc *crtc, s32 __user *fence_ptr) { @@ -546,6 +591,13 @@ static int drm_atomic_plane_set_property(struct drm_plane *plane, state->src_h = val; } else if (property == plane->pixel_source_property) { state->pixel_source = val; + } else if (property == plane->solid_fill_property) { + struct drm_property_blob *solid_fill = drm_property_lookup_blob(dev, val); + + ret = drm_atomic_set
