Subject: [PATCH v13 00/10] add DSC 1.2 dpu supports

This series adds the DPU side changes to support DSC 1.2 encoder. This
was validated with both DSI DSC 1.2 panel and DP DSC 1.2 monitor.
The DSI and DP parts will be pushed later on top of this change.
This seriel is rebase on [1], [2] and catalog fixes from rev-4 of [3].

Subject: [PATCH v13 03/10] drm/msm/dpu: add DPU_PINGPONG_DSC feature bit for DPU < 7.0.0

DPU < 7.0.0 requires the PINGPONG block to be involved during
DSC setting up. Since DPU >= 7.0.0, enabling and starting the DSC
encoder engine was moved to INTF with the help of the flush mechanism.
Add a DPU_PINGPONG_DSC feature bit to restrict the availability of
dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() on the
PINGPONG block to DPU < 7.0.0 hardware, as the registers are not
available on DPU 7.0.0 and higher anymore.
Add DPU_PINGPONG_DSC to PINGPONG_SDM845_MASK, PINGPONG_SDM845_TE2_MASK
and PINGPONG_SM8150_MASK which is used for all DPU < 7.0 chipsets.

changes in v6:
-- split patches and rearrange to keep catalog related files at this patch

changes in v7:
-- rewording commit text as suggested at review comments

changes in v9:
-- delete BIT(DPU_PINGPONG_DSC) from PINGPONG_SDM845_TE2_MASK

Subject: [PATCH v13 07/10] drm/msm/dpu: always clear every individual pending flush mask

There are two tiers of pending flush control, top levle and
individual hardware block. Currently only the top level of
flush mask is reset to 0 but the individual pending flush masks
of particular hardware blocks are left at their previous values,
eventually accumulating all possible bit values and typically
flushing more than necessary.
Reset all individual hardware blocks flush masks to 0 to avoid
individual hardware block be triggered accidentally.

Changes in V13:
-- rewording commi ttext
-- add an empty space line as suggested

Subject: [PATCH v13 08/10] drm/msm/dpu: separate DSC flush update out of interface

Currently DSC flushing happens during interface configuration at
dpu_hw_ctl_intf_cfg_v1(). Separate DSC flush away from
dpu_hw_ctl_intf_cfg_v1() by adding dpu_hw_ctl_update_pending_flush_dsc_v1()
to handle both per-DSC engine and DSC flush bits at same time to make it
consistent with the location of flush programming of other DPU sub-blocks.

Changes in v10:
-- rewording commit text
-- pass ctl directly instead of dpu_enc to dsc_pipe_cfg()
-- ctx->pending_dsc_flush_mask = 0;

Changes in v11:
-- add Fixes tag
-- capitalize MERGE_3D, DSPP and DSC at struct dpu_hw_ctl_ops{}

Changes in v12:
-- move dsc parameter to next line at dpu_encoder_dsc_pipe_cfg()

Subject: [PATCH v13 09/10] drm/msm/dpu: add DSC 1.2 hw blocks for relevant chipsets

From: Abhinav Kumar <[email protected]>

Add DSC 1.2 hardware blocks to the catalog with necessary sub-block and
feature flag information. Each display compression engine (DCE) contains
dual DSC encoders so both share same base address but with its own
different sub block address.

changes in v4:
-- delete DPU_DSC_HW_REV_1_1
-- re arrange sc8280xp_dsc[]

changes in v4:
-- fix checkpatch warning

changes in v10:
-- remove hard slice from commit text
-- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN
-- change DSC_BLK_1_2 .len from 0x100 to 0x29c

changes in v11:
-- remove comment at DSC_BLK_1_2 marco

Subject: [PATCH v13 04/10] drm/msm/dpu: Guard PINGPONG DSC ops behind DPU_PINGPONG_DSC bit

DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires
both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be
executed to complete DSC configuration if DSC hardware block is present.
Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions
to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set.

Changes in v6:
-- split patches, this patch has function handles DPU_PINGPONG_DSC bit

Changes in v9:
-- the original code of assigning dsc related functions to the ops of
pingpong block without testing the DPU_PINGPONG_DSC feature bit was
restored back due to rebase error which defeat the purpose of this
patch. Remove those error code.

Changes in v10:
-- change commit title
-- correct texts at changes in v9

Changes in v12:
-- fixed length too long at Changes in v9

be = from being

triggered = flushed?

(You just said "individual hardware block", it would be okay to refer to
that with just "Reset all individual hardware block flush masks to 0 to

But MERGE_3D and DSPP documentation entries were removed some time
later, though this is not reflected anywhere in the changelog.
