Subject: [PATCH v4 00/22] drm/msm/dpu: Implement tearcheck support on INTF
block
Since DPU 5.0.0 the TEARCHECK registers and interrupts moved out of the
PINGPONG block and into the INTF. 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 v4:
- Drop indentation changes from patch 17/21 by initially reserving
enough in 10/21;
- Drop documentation indentation changes in patch 18/21;
- Drop existing "TODO TE sub-blocks" from SM8550 in patch 18/21;
- Drop TE2 sub-block and feature flag from all DPU >= 5.0.0 instead of
just DPU >= 7.0.0 hardware (patch 2/21);
- Use double tabs in SC8280XP PP newline indentation to match the
other files, and not having to change it every time the opening
brace of the macro changes;
- Drop review tags after changing this patch significantly;
- Insert new patch that sets the PINGPONG block length to zero on DPU >=
7.0.0 via the PP_BLK_DITHER macro.
v3: https://lore.kernel.org/r/20230411-dpu-intf-te-v3-0-693b17fe6500@somainline.org
Changes in v3:
- Use new commit hashes in Fixes: tags after drm-msm's msm-next was
force-pushed;
- Rename dpu_hw_setup_vsync_source to
dpu_hw_setup_vsync_source_and_vsync_sel and drop _v1 suffix from
dpu_hw_setup_vsync_source_v1;
- Refactor dpu_hw_interrupts register offsets to take the block offset
as argument and compute the actual register with a base offset and
stride, rather than hardcoding the many per-INTF and per-AD4 register
offsets with fixed stride manually;
- Split INTF_TEAR interrupt additions into a core (dpu_hw_interrupts.c)
and catalog patch;
- Add new patch to make DITHER sub-block of SM8[34]50 and SC8280XP V2
instead of V1.
v2: https://lore.kernel.org/r/20230411-dpu-intf-te-v2-0-ef76c877eb97@somainline.org
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.
