dev_pm_qos_update_flags(9)

💅 dev_pm_qos_update_flags 💅

okay so bestie, we're in the Kernel API Manual, section 9, and this page is literally about dev_pm_qos_update_flags. It's giving power-management group chat, but make it kernel. No cap. 💖

🌸 NAME 🌸

dev_pm_qos_update_flags — updates the PM QoS flags request owned by user space. Periodt. 💖

✨ SYNOPSIS ✨

int dev_pm_qos_update_flags (struct device *dev , s32 mask , bool set );

yep, that's the whole signature: it returns an int and takes a struct device *, an s32 mask, and a bool set. Slay. ✨

💅 ARGUMENTS 💅

• dev — the device to update the PM QoS flags request for. Like, this is the struct device * in question, bestie. 🫶
• mask — the flags to set/clear. Simple as that. 🎀
• set — whether to set or clear the flags; true means set. So if you want the set vibe, pass true, iykyk. 💅
