💅 dev_pm_qos_...stor_request(9)

okay so bestie, welcome to the Kernel API Manual 🎀 — yes we're reading kernel docs together, this is our bonding era, no cap.

✨ NAME ✨

dev_pm_qos_add_ancestor_request — literally adds a PM QoS request for a device's ancestor. That's it, that's the whole vibe. 👑

🌸 SYNOPSIS 🌸

int dev_pm_qos_add_ancestor_request (struct device *dev , struct
       dev_pm_qos_request *req , enum dev_pm_qos_req_type type , s32 value );

like… yes she's a function, yes she returns an int, we move 💅

🦋 ARGUMENTS 🦋

  • dev — the device whose ancestor we're adding the request for. not the device itself, bestie, the ancestor — read it again, iykyk 👀
  • req — pointer to the preallocated handle. preallocated!! you gotta bring your own handle, it's giving bring-your-own-beverage 🥤
  • type — the type of the request. that's the enum dev_pm_qos_req_type energy ✨
  • value — the constraint latency value, a lil s32. it's the number, it's the moment 🍓

💜 SEE ALSO 💜

Kernel file ./drivers/base/power/qos.c — and honestly the whole friend group showed up for this one, so let's give them all their moment 🫶:

like, the whole squad. main character energy all around 👑

reminder bestie: this page lives under ./drivers/base/power, and it's dated October 2026 — so yeah, future-coded of it 💀📅

and that's the page!! go forth and add those ancestor requests, you absolute icon 🌈🦋 mwah 💖
