From 043e5b302625634f5590f3da09652cdfa1037851 Mon Sep 17 00:00:00 2001 From: Abhinav Kumar Date: Tue, 12 Dec 2023 12:52:39 -0800 Subject: [PATCH] drm/msm/dpu: add formats check for writeback encoder In preparation for adding more formats to dpu writeback add format validation to it to fail any unsupported formats. changes in v4: - change the failure message of the API drm_atomic_helper_check_wb_connector_state() to a generic one in case it checks more errors later and moreoever it already has debug message to indicate its failure - change the corresponding DPU_ERROR to DPU_DEBUG in-line with other atomic_check failure messages changes in v3: - rebase on top of msm-next - replace drm_atomic_helper_check_wb_encoder_state() with drm_atomic_helper_check_wb_connector_state() due to the rebase changes in v2: - correct some grammar in the commit text Fixes: d7d0e73f7de3 ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback") Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/571811/ Link: https://lore.kernel.org/r/20231212205254.12422-2-quic_abhinavk@quicinc.com [DB: removed extra debug message] Signed-off-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c index bb94909caa254..798d33e3207f6 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c @@ -272,6 +272,7 @@ static int dpu_encoder_phys_wb_atomic_check( { struct drm_framebuffer *fb; const struct drm_display_mode *mode = &crtc_state->mode; + int ret; DPU_DEBUG("[atomic_check:%d, \"%s\",%d,%d]\n", phys_enc->hw_wb->idx, mode->name, mode->hdisplay, mode->vdisplay); @@ -308,7 +309,7 @@ static int dpu_encoder_phys_wb_atomic_check( return -EINVAL; } - return 0; + return drm_atomic_helper_check_wb_connector_state(conn_state->connector, conn_state->state); } -- 2.30.2
