Have msm8953 and msm8996 migrated to DPU or is there a series planned to migrate them? The change itself is correct but without the catalogs for those chipsets merged, we will never hit this path. > Signed-off-by: Barnabás Czémán <trabarni@gmail.com> > --- > drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c > index 489be1c0c704..250d83af53a4 100644 > --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c > +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c > @@ -298,7 +298,7 @@ static void dpu_encoder_phys_cmd_irq_enable(struct dpu_encoder_phys *phys_enc) > phys_enc); > dpu_encoder_phys_cmd_control_vblank_irq(phys_enc, true); > > - if (dpu_encoder_phys_cmd_is_master(phys_enc)) > + if (dpu_encoder_phys_cmd_is_master(phys_enc) && phys_enc->irq[INTR_IDX_CTL_START]) > dpu_core_irq_register_callback(phys_enc->dpu_kms, > phys_enc->irq[INTR_IDX_CTL_START], > dpu_encoder_phys_cmd_ctl_start_irq, > @@ -311,7 +311,7 @@ static void dpu_encoder_phys_cmd_irq_disable(struct dpu_encoder_phys *phys_enc) > phys_enc->hw_pp->idx - PINGPONG_0, > phys_enc->vblank_refcount); > > - if (dpu_encoder_phys_cmd_is_master(phys_enc)) > + if (dpu_encoder_phys_cmd_is_master(phys_enc) && phys_enc->irq[INTR_IDX_CTL_START]) > dpu_core_irq_unregister_callback(phys_enc->dpu_kms, > phys_enc->irq[INTR_IDX_CTL_START]); > > > --- > base-commit: 704ba27ac55579704ba1289392448b0c66b56258 > change-id: 20240509-ctl_irq-a90b2d7a0bf5 > > Best regards,
There was some previously sent patch series made by Dmitry for these soc, msm8996 was sent together by sdm660 but in the last version it was dropped. I have recreated msm8996 DPU support from that series but it will need some more test. I am testing msm8953 series but it is depend on msm8996.

CTLs on older qualcomm SOCs like msm8953 and msm8996 has not got interrupts, so better to skip CTL irq callback register/unregister make dpu_ctl_cfg be able to define without intr_start.
