dev_pm_qos_remove_notifier(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… dev_pm_qos_remove_notifier πŸ’…

okay so real talk bestie, this is a page from the Kernel API Manual β€” like, the actual manual for dev_pm_qos_remove_notifier. yes the name is a mouthful. no we are not shortening it. it's iconic, it's giving "I have a long name and I'm not sorry." πŸŽ€


✨ NAME ✨

dev_pm_qos_remove_notifier β€” deletes notification for changes to target value of per-device PM QoS constraints πŸ¦‹

like, it's the un-subscribe button. for notifications. about constraint target values. per device. that's the whole vibe.


🌸 SYNOPSIS 🌸

int dev_pm_qos_remove_notifier (struct device *dev , struct
notifier_block *notifier , enum dev_pm_qos_req_type type );

yep, three args, returns an int, go off king πŸ‘‘


πŸ’– ARGUMENTS πŸ’–

  • dev β€” target device for the constraint. the main character, literally. everything happens for this device.
  • notifier β€” notifier block to be removed. the one getting kicked out of the group chat 🫢
  • type β€” request type. which flavor of request we're talking about here, iykyk.

πŸ”₯ DESCRIPTION πŸ”₯

Will remove the notifier from the notification chain that gets called upon changes to the target value.

that's it. that's the whole job. it's a removal. it un-registers. it takes the notifier out of the chain that fires whenever the target value changes, so it stops getting pinged. no more callbacks for that block. slay, honestly. ✨


🌈 SEE ALSO 🌈

sibling functions!! the whole qos family reunion, all referenced from the kernel file ./drivers/base/power/qos.c β€” go read it, it ate πŸ’€

pro tip bestie: dev_pm_qos_add_notifier(9) is right there in the list and it's literally the opposite of this one. they're a matched set. add it, remove it. balanced. as all things should be ⭐


🧚 sign-off 🧚

this little chapter lives under ./drivers/base/power, dated October 2026, and it's part of the dev_pm_qos_remove_notifier(9) page itself β€” so yeah, that's the whole thing, start to finish, no crumbs left. go forth and remove those notifiers responsibly, bestie. mwah πŸ’œπŸŽ€πŸŒΈ
