dev_pm_qos_remove_request(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, you're on the dev_pm_qos_remove_request(9) page in the Kernel API Manual, and it's lowkey all about taking an existing qos request out of the mix and refreshing the target value. slay 💅

✨ NAME ✨

dev_pm_qos_remove_request — modifies an existing qos request

🌸 SYNOPSIS 🌸

int dev_pm_qos_remove_request (struct dev_pm_qos_request *req );

🎀 ARGUMENTS 🎀

  • req — handle to request list element. literally your little handle to the request list element, bestie 🫶

💖 DESCRIPTION 💖

It will remove the pm qos request from the list of constraints and recompute the current target value. Call this on slow code paths — yes, this one is giving slow-path main character energy, so use it there. 🐢✨

Return values, no cap:

  • 1 if the aggregated constraint value has changed
  • 0 if the aggregated constraint value has not changed
  • -EINVAL in case of wrong parameters
  • -ENODEV if the device has been removed from the system
⚠️ Callers should ensure that the target device is not RPM_SUSPENDED before using this function for requests of type DEV_PM_QOS_FLAGS. this is the “check the vibe before you touch it” part, fr fr 💀
