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 Signed-off-by: Jessica Zhang --- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 9 +++- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 65 ++++++++++++++--------- 2 files changed, 49 insertions(+), 25 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c index 13ce321283ff..0695b70ea1b7 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c @@ -409,6 +409,7 @@ static void _dpu_crtc_blend_setup_mixer(struct drm_crtc *crtc, struct drm_plane_state *state; struct dpu_crtc_state *cstate = to_dpu_crtc_state(crtc->state); struct dpu_plane_state *pstate = NULL; + const struct msm_format *fmt; struct dpu_format *format; struct dpu_hw_ctl *ctl = mixer->lm_ctl; @@ -441,7 +442,13 @@ static void _dpu_crtc_blend_setup_mixer(struct drm_crtc *crtc, sspp_idx - SSPP_VIG0, state->fb ?
