divvy_up_power(9)

📦 version 7.3.1, in nixpkgs unstable

💅 divvy_up_power — kernel API manual, bestie edition 🎀

okay so real talk, we're in the divvy_up_power(9) page from the Kernel API Manual, and honestly? it's giving "fair share" energy and i'm obsessed. let's get into it ✨

✨ NAME ✨

divvy_up_power — divvy the allocated power between the actors 🫶

like, literally. it's in the name. it divides. it shares. it slays.

🌸 SYNOPSIS 🌸

void divvy_up_power (struct power_actor *power , int num_actors , u32
total_req_power , u32 power_range );

no cap, that's the whole signature. copy it exactly, don't come for me 🙈

🦋 ARGUMENTS 🦋

  • power — buffer for all power actors internal power information 💖 this is where each actor's lil internal deets live
  • num_actors — number of power actors in this thermal zone 🔥 count 'em
  • total_req_power — sum of all weighted requested power for all actors 🌈 the grand total of everyone's weighted asks
  • power_range — total allocated power 👑 the actual bag we're splitting up

💜 DESCRIPTION 💜

okay so here's the vibe: this function divides the total allocated power (power_range) fairly between the actors. fair as in, no main character hogging the whole thing. periodt. 💅

first pass? it tries to give each actor a share of the power_range according to how much power it requested compared to the rest of the actors. it's proportional, it's cute, it's math. for example:

  • if only one actor requests power, then it receives all the power_range 🎀 (lucky them, honestly)
  • if three actors each requests 1mW, each receives a third of the power_range ⚖️ (balanced. iconic. no notes.)

and then the plot twist 🫢 — if any actor received more than their maximum power, then that surplus is re-divvied among the actors based on how far they are from their respective maximums. yeah, the leftovers get redistributed. nothing wasted, nothing extra. chef's kiss.

ngl bestie, if you're touching thermal zone power allocation, read the whole squad above. iykyk 💀

and that's the page!! 🎉 ty for coming to my ted talk, this dropped out of ./drivers/thermal back in October 2026 and it's still serving. mwah 💋✨💖
