Subject: [PATCH 11/20] drm/amd/display: Separate ABM functions into dedicated power_abm.c file
Date: Wed, 6 May 2026 12:31:09 +0800 [thread overview]
Message-ID: <20260506043342.2164710-12-PingLei.Lin@amd.com> (raw)
In-Reply-To: <20260506043342.2164710-1-PingLei.Lin@amd.com>
From: Lohita Mudimela <lohita.mudimela@amd.com>
[Why]
Improves code organization by separating Adaptive Backlight
Modulation functionality from general power management.
This modular approach enhances maintainability and makes the
codebase easier to navigate.
[How]
Create new power_abm.c file containing all ABM-related functions moved from power.c.
Remove static qualifier from shared functions to enable cross-file access:
- initialize_backlight_caps: Initialize backlight capabilities
- validate_ext_backlight_caps: Validate external backlight capabilities
- backlight_millipercent_to_pwm: Convert brightness percent to PWM
- backlight_millipercent_to_millinit: Convert brightness percent to nits
- fill_backlight_level_params: Populate backlight level parametersAdd function
declarations to mod_power.h header. Update CMakeLists.txt to include power_abm.c in build.
Maintain forward declaration of struct core_power for type compatibility.
Rename struct core_power field from 'public' to 'mod_public'.
Move internal structures (backlight_state, backlight_properties,
dmcu_varibright_cached_properties, core_power) to power_helpers.h to
ensure consistent memory layouts across compilation units.
