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) 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 | 69 +++++++++++++---------- drivers/gpu/drm/drm_atomic_helper.c | 34 ++++++----- drivers/gpu/drm/drm_atomic_state_helper.c | 9 +++ drivers/gpu/drm/drm_atomic_uapi.c | 64 +++++++++++++++++++++ drivers/gpu/drm/drm_blend.c | 17 ++++++ drivers/gpu/drm/drm_plane.c | 20 +++++-- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 9 ++- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 69 +++++++++++++++-------- include/drm/drm_atomic_helper.h | 6 +- include/drm/drm_blend.h | 1 + include/drm/drm_plane.h | 34 +++++++++++ 11 files changed, 257 insertions(+), 75 deletions(-)
