[RFC PATCH v3 0/3] Support for Solid Fill Planes
Introduce and add support for a solid_fill property. When the solid_fill property is set, and the framebuffer is set to NULL, memory fetch will be disabled. In addition, loosen the NULL FB checks within the atomic commit callstack to allow a NULL FB when the solid_fill property is set and add FB checks in methods where the FB was previously assumed to be non-NULL. Finally, have the DPU driver use drm_plane_state.solid_fill and instead of dpu_plane_state.color_fill, and add extra checks in the DPU atomic commit callstack to account for a NULL FB in cases where solid_fill is set. 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. Userspace can set the solid_fill property to a blob containing the appropriate version number and solid fill color (in RGB323232 format) and setting the framebuffer to NULL. Note: 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. Changes in V2: - Dropped SOLID_FILL_FORMAT property (Simon) - Switched to implementing solid_fill property as a blob (Simon, Dmitry) - 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) 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) Jessica Zhang (3): drm: Introduce solid fill property for drm plane drm: Adjust atomic checks for solid fill color drm/msm/dpu: Use color_fill property for DPU planes drivers/gpu/drm/drm_atomic.c | 136 +- drivers/gpu/drm/drm_atomic_helper.c | 34 +++--- drivers/gpu/drm/drm_atomic_state_helper.c | 9 ++ drivers/gpu/drm/drm_atomic_uapi.c | 59 ++ drivers/gpu/drm/drm_blend.c | 17 +++ drivers/gpu/drm/drm_plane.c | 8 +- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 9 +- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 65 +++ include/drm/drm_atomic_helper.h | 5 +- include/drm/drm_blend.h | 1 + include/drm/drm_plane.h | 62 ++ 11 files changed, 302 insertions(+), 103 deletions(-) -- 2.38.1
[RFC PATCH v3 2/3] drm: Adjust atomic checks for solid fill color
Loosen the requirements for atomic and legacy commit so that, in cases
where solid fill planes is enabled (and FB_ID is NULL), the commit can
still go through.
In addition, add framebuffer NULL checks in other areas to account for
FB being NULL when solid fill is enabled.
Changes in V2:
- Changed to checks for if solid_fill_blob is set (Dmitry)
- Abstracted (plane_state && !solid_fill_blob) checks to helper method
(Dmitry)
- Fixed indentation issue (Dmitry)
Changes in V3:
- 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)

[RFC PATCH v3 1/3] drm: Introduce solid fill property for drm plane
Add support for solid_fill property to drm_plane. 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)
Changes in V3:
- Corrected typo in drm_solid_fill struct documentation

[RFC PATCH v3 3/3] drm/msm/dpu: Use color_fill property for DPU planes
Initialize and use the color_fill properties for planes in DPU driver. In
addition, relax framebuffer requirements within atomic commit path and
add checks for NULL framebuffers. Finally, drop DPU_PLANE_COLOR_FILL_FLAG
as it's unused.
Changes since V2:
- Fixed dropped 'const' warning
- Dropped use of solid_fill_format
- Switched to using drm_plane_solid_fill_enabled helper method
- Added helper to convert color fill to BGR888 (Rob)
- Added support for solid fill on planes of varying sizes
- Removed DPU_PLANE_COLOR_FILL_FLAG

Re: [RFC PATCH v3 1/3] drm: Introduce solid fill property for drm plane
On 05/01/2023 01:40, Jessica Zhang wrote:
Add support for solid_fill property to drm_plane. 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;
BTW: should we add support for alpha too? DPU hardware supports using
RGBA as a fill colour format, doesn't it?
But then we face the obvious question, how do we communicate to
userspace if the hardware support RGB or RGBA?
};
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)
Changes in V3:
- Corrected typo in drm_solid_fill struct documentation

Re: [RFC PATCH v3 3/3] drm/msm/dpu: Use color_fill property for DPU planes
On 05/01/2023 01:40, Jessica Zhang wrote:
Initialize and use the color_fill properties for planes in DPU driver. In
addition, relax framebuffer requirements within atomic commit path and
add checks for NULL framebuffers. Finally, drop DPU_PLANE_COLOR_FILL_FLAG
as it's unused.
Changes since V2:
- Fixed dropped 'const' warning
- Dropped use of solid_fill_format
- Switched to using drm_plane_solid_fill_enabled helper method
- Added helper to convert color fill to BGR888 (Rob)
- Added support for solid fill on planes of varying sizes
- Removed DPU_PLANE_COLOR_FILL_FLAG

I think this should be more explicit:

else

And in the _dpu_crtc_blend_setup_mixer() too.
