power_actor_set_power(9)

💖 bestie's guide to power_actor_set_power(9) 💖

okay so you opened the power_actor_set_power(9) page — welcome to the Kernel API Manual, but make it cute and useful. This is the one about limiting the maximum power a cooling device consumes. no cap, it's giving thermal-management main character energy. 🧚

🌸 NAME 🌸

power_actor_set_power — limit the maximum power a cooling device consumes

✨ SYNOPSIS ✨

int power_actor_set_power (struct thermal_cooling_device *cdev , struct
       thermal_instance *instance , u32 power );

🎀 ARGUMENTS 🎀

• cdev — pointer to thermal_cooling_device
• instance — thermal instance to update
• power — the power in milliwatts

🦋 DESCRIPTION 🦋

Set the cooling device to consume at most power milliwatts. The limit is expected to be a cap at the maximum power consumption. periodt. That's the vibe: a max-power ceiling, bestie. 💅

💜 RETURN 💜

• 0 on success, -EINVAL if the cooling device does not implement the power actor API, or -E* for other failures.
