As of commit ef58e0ad3436 ("drm/msm/dpu: get INTF blocks directly rather than through RM") the hw resources struct was removed, leaving struct dpu_rm_requirements containing a single field (topology). Remove the useless wrapper.

Moreover if at some point the driver supports encoder cloning, allocating resources from the encoder will be incorrect, as all clones will have different encoder IDs, while LMs are to be shared by these encoders.

For concurrent writeback, the realtime encoder must always kickoff last as it will call the trigger flush and start. This avoids the following scenario where the writeback encoder increments the pending kickoff count after the WB_DONE interrupt is fired: If the realtime encoder is kicked off first, the encoder kickoff will flush/start the encoder and increment the pending kickoff count. The WB_DONE interrupt then fires (before the writeback encoder is kicked off). When the writeback encoder enters its kickoff, it will skip the flush/start (due to CWB being enabled) and hit a frame done timeout as the frame was kicked off (and the WB_DONE interrupt fired) without the pending kickoff count being incremented. In addition, the writeback timer should only start after the realtime encoder is kicked off to ensure that we don't get timeouts when the system has a heavy load (ex. when debug logs are enabled) Signed-off-by: Jessica Zhang --- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 74 ++++++++++++++++++++++++++------ 1 file changed, 60 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c index 22d135c8c8be498533b6730fbd0077628b846989..c7c903b04d7f411e81d7cd1c1bf7e1f3bcec112b 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c @@ -928,6 +928,45 @@ static int _dpu_crtc_wait_for_frame_done(struct drm_crtc *crtc) return rc; } +static int dpu_crtc_kickoff_clone_mode(struct drm_crtc *crtc) +{ + struct drm_encoder *encoder; + struct drm_encoder *rt_encoder = NULL, *wb_encoder; + struct dpu_kms *dpu_kms = _dpu_crtc_get_kms(crtc); + + /* Find encoder for real time display */ + drm_for_each_encoder_mask(encoder, crtc->dev, + crtc->state->encoder_mask) { + if (encoder->encoder_type == DRM_MODE_ENCODER_VIRTUAL) + wb_encoder = encoder; + else + rt_encoder = encoder; + } + + if (!rt_encoder || !wb_encoder) { + DRM_DEBUG_ATOMIC("real time or wb encoder not found\n"); + return -EINVAL; + } + + dpu_encoder_prepare_for_kickoff(wb_encoder); + dpu_encoder_prepare_for_kickoff(rt_encoder); + + dpu_vbif_clear_errors(dpu_kms); + + /* + * Kickoff real time encoder last as it's the encoder that + * will do the flush + */ + dpu_encoder_kickoff(wb_encoder); + dpu_encoder_kickoff(rt_encoder); + + /* Don't start frame done timers until the kickoffs have finished */ + dpu_encoder_start_frame_done_timer(wb_encoder); + dpu_encoder_start_frame_done_timer(rt_encoder); + + return 0; +} + void dpu_crtc_commit_kickoff(struct drm_crtc *crtc) { struct drm_encoder *encoder; @@ -952,13 +991,27 @@ void dpu_crtc_commit_kickoff(struct drm_crtc *crtc) goto end; } } - /* - * Encoder will flush/start now, unless it has a tx pending.
