Subject: [PATCH v6 00/14] drm/msm: Add Display Stream Compression Support
Date: Mon, 4 Apr 2022 22:04:22 +0530 [thread overview]
Message-ID: <20220404163436.956875-1-vkoul@kernel.org> (raw)
Display Stream Compression (DSC) compresses the display stream in host which
is later decoded by panel. This series enables this for Qualcomm msm driver.
This was tested on Google Pixel3 phone which use LGE SW43408 panel.
The changes include DSC data and hardware block enabling for DPU1 then
support in encoder. We also add support in DSI and introduce required
topology changes.
In order for panel to set the DSC parameters we add dsc in drm_panel and
pass the dsc configuration from the panel driver
Complete changes which enable this for Pixel3 along with panel driver (not
part of this series) and DT changes can be found at:
git.linaro.org/people/vinod.koul/kernel.git pixel/dsc_v6
Comments welcome!
Changes since v5:
- rebase on msm-next
- use generated header patch from mesa for dsc registers
- use generated header macros for dsc register calculation
- remove msm dsc struct (Dmitry)
Changes since v4:
- Use new apprach based on Abhinav suggestion for dsc with 3d-merge
- Make common function for dsc timing caln and call that from video and cmd
mode
- update description for patch "Pass DSC params to drm_panel"
- update couple of typos as pointed by Marijn
- drop dpu_encoder_dsc_pclk_param_calc() as that was duplicating the caln
done in dsi timing
- Update copyright to 2022 to new files
- Update Abhinav's email to new quic one
Changes since v3:
- Merge changes from Dmitry to have dsc per encoder instance
- add warning for dsc and mode3d enabled together
- set dsc in dpu_encoder_phys_vid as well
- remove dsc hardcoded mask
- use devm_kzalloc for memory allocation for dsc
Changes since v2:
- Fix comments by Dimitry except the dsc being global.
- Move RM patch later for dependency on topology now
- Add patch for mode valid callback for dsi_mgr
- Add missing structure documentation patch
- Fix errors in mode_3d changes
- Rebase on v5.16-rc1 and test
Changes since v1:
- Fix various issues spotted by kbuildbot
- Rebase to v5.15-rc3
- Remove unused fields and duplicate defines
- Enable DSC blocks only when DSC is enabled
- remove sdm845 feature mask, use 0
- Check for DSC in hw_ctl
Changes since RFC:
- Drop the DT binding patch as we derive the configuration from panel
- Drop the drm api patch as we no longer need it (use pps drm api)
- Fix comments raised by Dimitry
- Add dsc parameters calculation from downstream
