max_node_power_limit(9)

🦋 max_node_power_limit 💅🦋

okay so this is page max_node_power_limit(9) from the Kernel API Manual, and it's giving tiny-but-important sysfs energy ✨ no cap.

The amdgpu driver provides a sysfs API for retrieving maximum node power limit. The file max_node_power_limit is used for this. That's the whole lore, bestie 💖 slay.
