STRUCT AMDXDNA_DRM_SET_POWER_MODE(9)

💅 struct amdxdna_drm_set_power_mode(9) — from the Kernel API Manual, section 9, bestie

okay so picture this: you're deep in the kernel API manual, section 9, and you've stumbled onto this little icon. it's a struct. it's giving "small but powerful." and honestly? it's the one that tells the AIE hardware what power mode to vibe in. no cap.

---

✨ NAME ✨

struct amdxdna_drm_set_power_mode — Set the power mode of the AIE hardware 🎀

like, that's literally its whole job and it does it slayfully.

---

🌸 SYNOPSIS 🌸

struct amdxdna_drm_set_power_mode {
    __u8 power_mode;
    __u8 pad[7];
 };

look at her. two members. absolutely zero filler (well, except the padding, but we'll get to that 💀).

---

👑 Members 👑

• power_mode — the sensor type, taken from enum amdxdna_power_mode_type. yes bestie, it's an enum value living its best life inside a __u8. iconic.
• pad — MBZ. that's "must be zero," so don't be cute and put random stuff in there, okay? 🫶 it's padding, it's decorative, it's not the main character. leave it be.

🦋 SEE ALSO 🦋

the kernel file itself lives at ./include/uapi/drm/amdxdna_accel.h — that's where the struct actually hangs out, iykyk.

and because this struct does not exist in a vacuum, here's the whole friend group, fr fr — every single one of them:

• struct amdxdna_drm_create_hwctx(9)
• struct amdxdna_drm_destroy_hwctx(9)
• struct amdxdna_cu_config(9)

note how struct amdxdna_drm_get_power_mode(9) is right there in the mix 👀 — the getter and the setter, a matched set, the way that they're literally siblings. obsessed.

💖 quick vibe check: power_mode is one __u8 and pad is seven. that's eight bytes total and she is perfectly aware of it.

✨ that's the whole page, bestie ✨ this little gem comes from the path ./include/uapi/drm, dated October 2026, and yeah — the header on the sheet says struct amdx...t_power_mode(9) which is just the title getting cut off mid-yawn 💀 but you knew that. mwah. 💋
