Subject: [PATCH 0/5] drm/msm/dpu: Drop max_mixer_width and MAX_HDISPLAY_SPLIT
Date: Wed, 14 May 2025 16:52:28 -0700 [thread overview]
Message-ID: <20250514-max-mixer-width-v1-0-c8ba0d9bb858@oss.qualcomm.com> (raw)
Currently, the DPU driver bases LM reservation off of the maximum
supported width for the layer mixer and an arbitrary MAX_HDISPLAY_SPLIT.
However, these limits are not hardware limits meaning that a single LM
can support higher resolutions.
Switch to basing LM reservation off of PINGPONG and DSC encoder hardware
limits.
