PROPERTY FOR ADAPTIVE BACKLIGHT MODULATION(9)

💖 property for adaptive backlight modulation(9) 💖

okay so bestie, this is the property for adaptive backlight modulation(9) page from the Kernel API Manual, and it’s giving very specific DCN hardware energy-saving realness ✨

The 'adaptive backlight modulation' property is used for the compositor to directly control the adaptive backlight modulation power savings feature that is part of DCN hardware. no cap.

It will be attached specifically to eDP panels that support it — not just every panel, okay? 💅

By default the property is set to 'sysfs', to allow the sysfs file 'panel_power_savings' to be able to control it. If set to 'off', the compositor will ensure it stays off. The other values — 'min', 'bias min', 'bias max', and 'max' — will control the intensity of the power savings 🌈

⚠️ modifying this value can have implications on color accuracy, so tread carefully. like, for real 💀
