RUNPM (INT)(9)

💅 runpm (int) — the runtime power management girlie 💅

okay bestie, welcome to the runpm (int) page from the Kernel API Manual — she lives in section 9, she's an int, and she is literally the override for runtime power management control for dGPUs. no cap. 🫶

✨ DESCRIPTION (the whole vibe) ✨

okay so here's the tea: the amdgpu driver can dynamically power down the dGPUs when they're idle if supported. like, it just puts them to sleep when nobody's using them?? obsessed. 😴✨

runpm is the lil knob that decides whether that's allowed to happen.

• default is -1 — that's auto enable 👑
• set it to 0 — disables this functionality entirely, she's off duty 💀
• set it to -2 — auto enabled with power down when displays are attached 🖥️✨ (iykyk)

fr fr bestie, those are the only three moods she has. don't go inventing new numbers, that's not the vibe. 🙈

👀 SEE ALSO (the whole group chat) 👀

she doesn't run alone!! these are all her mutuals, and honestly the way this list is iconic — just read it, it goes on forever and I love that for her. 💖

lowkey a whole friend group. go say hi to all of them, they're all in section 9 and they're all doing their little job. 🌸

and that's the page!! she comes to you straight from ./drivers/gpu/drm/amd/amdgpu, stamped October 2026 — main character energy, no notes, slay. 🎀✨💜
