Implement the necessary callbacks in the INTF block, and use these callbacks together with the INTF_TEAR interrupts. Additionally, disable previous register writes and remove unused interrupts in the PINGPONG and MDP_TOP blocks for these newer platforms. With these patches the devices on DPU >= 5.0.0 listed below now update their panels at 60fps without tearing (nor sluggishness), and without repeated timeouts in dmesg. Tested on the following devices with command-mode panels and TE pins: - Sony Xperia XZ3 (sdm845, DPU 4.0.0, cmdmode panel): no regressions on PINGPONG TE; - Sony Xperia 5 (sm8150, DPU 5.0.0); - Sony Xperia 10 II (sm6125, DPU 5.0.4). --- Changes in v2: - Rebase on -next with all the new SC8280XP and SM8[345]50 support; - Remove duplicate PP_BLK_TE macro now that .features is an argument; - Fix PP_BLK_DIPHER -> DITHER typo that was added recently; - Add INTF_TEAR interrupt blocks for DPU 7.0.0 (moved to different register range); - Describe INTF_TEAR support for the newly added SM8350, SM8450, SM8550 and SC8280XP SoCs; - Remove TE2 subblocks from 8[34]50 and sc8280xp (new patch); - Rebase on -next with DPU catalog rework; - Remove dpu_hw_intf_v1_get_status which was inlined in the original dpu_hw_intf_get_status function in e3969eadc8ee ("drm/msm/disp/dpu: get timing engine status from intf status register"); - Many changes to move all catalog edits to separate files; - Add documentation for DPU_MDP_VSYNC_SEL; - Fix sdm8150_mdp typo, should be sm8150_mdp; - Move unrelated INTF_INTR offsets out of hwio header (new patch); - Remove _reg argument from INTF_BLK, since we now have a third interrupt with a different base register. To prevent confusion all three interrupts should provide the final value from DPU_IRQ_IDX directly. - Only request the new tear_rd_ptr in a new INTF_BLK_DSI_TE macro; - Drop stray INTF_MISR_SIGNATURE register definition; - Clean up registers in dpu_hw_intf.c (many new patches); - merged setup_tearcheck() and enable_tearcheck() callbacks; - replaced enable_tearcheck(false) with new disable_tearcheck() callback; - Moved dpu_encoder_phys_cmd_enable_te intestines (just autorefresh disablement) to INTF and PP block, replacing 3 callbacks in both blocks with just a single disable_autorefresh() callback. v1: https://lore.kernel.org/r/20221231215006.211860-1-marijn.suijten@somainline.org --- Konrad Dybcio (1): drm/msm/dpu: Move dpu_hw_{tear_check,pp_vsync_info} to dpu_hw_mdss.h Marijn Suijten (16): drm/msm/dpu: Remove unused INTF0 interrupt mask from SM6115/QCM2290 drm/msm/dpu: Remove TE2 block and feature from DPU >= 7.0.0 hardware drm/msm/dpu: Move non-MDP_TOP INTF_INTR offsets out of hwio header drm/msm/dpu: Fix PP_BLK_DIPHER -> DITHER typo drm/msm/dpu: Remove duplicate register defines from INTF drm/msm/dpu: Remove extraneous register define indentation drm/msm/dpu: Sort INTF registers numerically drm/msm/dpu: Drop unused poll_timeout_wr_ptr PINGPONG callback drm/msm/dpu: Move autorefresh disable from CMD encoder to pingpong drm/msm/dpu: Disable pingpong TE on DPU 5.0.0 and above drm/msm/dpu: Disable MDP vsync source selection on DPU 5.0.0 and above drm/msm/dpu: Factor out shared interrupt register in INTF_BLK macro drm/msm/dpu: Document and enable TEAR interrupts on DSI interfaces drm/msm/dpu: Merge setup_- and enable_tearcheck pingpong callbacks drm/msm/dpu: Implement tearcheck support on INTF block drm/msm/dpu: Remove intr_rdptr from DPU >= 5.0.0 pingpong config .../drm/msm/disp/dpu1/catalog/dpu_3_0_msm8998.h | 26 +- .../gpu/drm/msm/disp/dpu1/catalog/dpu_4_0_sdm845.h | 26 +- .../gpu/drm/msm/disp/dpu1/catalog/dpu_5_0_sm8150.h | 40 +-- .../drm/msm/disp/dpu1/catalog/dpu_5_1_sc8180x.h | 48 ++-- .../gpu/drm/msm/disp/dpu1/catalog/dpu_6_0_sm8250.h | 40 +-- .../gpu/drm/msm/disp/dpu1/catalog/dpu_6_2_sc7180.h | 16 +- .../gpu/drm/msm/disp/dpu1/catalog/dpu_6_3_sm6115.h | 15 +- .../drm/msm/disp/dpu1/catalog/dpu_6_5_qcm2290.h | 15 +- .../gpu/drm/msm/disp/dpu1/catalog/dpu_7_0_sm8350.h | 40 +-- .../gpu/drm/msm/disp/dpu1/catalog/dpu_7_2_sc7280.h | 22 +- .../drm/msm/disp/dpu1/catalog/dpu_8_0_sc8280xp.h | 64 +++-- .../gpu/drm/msm/disp/dpu1/catalog/dpu_8_1_sm8450.h | 46 ++-- .../gpu/drm/msm/disp/dpu1/catalog/dpu_9_0_sm8550.h | 36 ++- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 11 + drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h | 10 +- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 210 ++++++++-------- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 48 ++-- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 9 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_interrupts.c | 32 ++- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_interrupts.h | 4 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_intf.c | 268 ++++++++++++++++++--- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_intf.h | 25 ++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_mdss.h | 48 ++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.c | 83 ++++--- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.h | 64 +---- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c | 52 ++-- drivers/gpu/drm/msm/disp/dpu1/dpu_hwio.h | 3 - drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 4 + drivers/gpu/drm/msm/disp/dpu1/dpu_trace.h | 14 ++ 29 files changed, 909 insertions(+), 410 deletions(-) --- base-commit: 4aa1da8d99724f6c0b762b58a71cee7c5e2e109b change-id: 20230411-dpu-intf-te-ea684f13e083 Best regards,
