Subject: [PATCH v2 00/11] drm/msm: Add Display Stream Compression Support
Date: Thu, 7 Oct 2021 12:38:49 +0530 [thread overview]
Message-ID: <20211007070900.456044-1-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 set
it from the msm 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_v2
Comments welcome!
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
