[PATCH 00/17] Add support for CDM over DP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


The Chroma Down Sampling (CDM) block is a hardware component in the DPU
pipeline that includes a CSC block capable of converting RGB input from
the DPU to YUV data.

This block can be used with either HDMI, DP, or writeback interfaces.
This series adds support for the CDM block to be used with DP in
YUV420 mode format.

This series allows selection of the YUV420 format for monitors which support
certain resolutions only in YUV420 thus unblocking the validation of many
other resolutions which were previously filtered out if the connector did
not support YUV420.

This was validated using a DP connected monitor requiring the use of
YUV420 format.

This series currently works as-is. But it was also validated to function on
top of in the case of future integration:


Kuogee Hsieh (1):
  drm/msm/dpu: add support of new peripheral flush mechanism

Paloma Arellano (16):
  drm/msm/dpu: allow dpu_encoder_helper_phys_setup_cdm to work for DP
  drm/msm/dpu: move dpu_encoder_helper_phys_setup_cdm to dpu_encoder
  drm/msm/dp: rename wide_bus_en to wide_bus_supported
  drm/msm/dp: store mode YUV420 information to be used by rest of DP
  drm/msm/dp: add an API to indicate if sink supports VSC SDP
  drm/msm/dpu: move widebus logic to its own API
  drm/msm/dpu: disallow widebus en in INTF_CONFIG2 when DP is YUV420
  drm/msm/dp: change YUV420 related programming for DP
  drm/msm/dp: move parity calculation to dp_catalog
  drm/msm/dp: modify dp_catalog_hw_revision to show major and minor val
  drm/msm/dp: add VSC SDP support for YUV420 over DP
  drm/msm/dp: enable SDP and SDE periph flush update
  drm/msm/dpu: modify encoder programming for CDM over DP
  drm/msm/dpu: allow certain formats for CDM for DP
  drm/msm/dpu: reserve CDM blocks for DP if mode is YUV420
  drm/msm/dp: allow YUV420 mode for DP connector when VSC SDP supported
