Subject: [PATCH v2 0/3] drm/msm/dpu: Drop max_mixer_width and MAX_HDISPLAY_SPLIT
Date: Sat, 03 Jan 2026 15:45:03 +0200 [thread overview]
Message-ID: <20260103-max-mixer-width-v2-0-ef5d3d246709@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.
---
Changes in v2:
- Dropped PP and DSC encoder width drop the catalog, they are now
determined in the code by using the DPU programming
- Corrected DSC encoder width for DPUs < 8.x (2048 vs 2560)
- Link to v1: https://lore.kernel.org/r/20250514-max-mixer-width-v1-0-c8ba0d9bb858@oss.qualcomm.com
