💖 dev_pm_qos_u...cy_tolerance(9) 💖

okay so bestie, this page is from the Kernel API Manual, and it's literally about updating user space latency tolerance. No cap, that's the whole mission. 🫶

🌸 NAME 🌸

dev_pm_qos_update_user_latency_tolerance — Update user space latency tolerance. That's it, that's the vibe. ✨

✨ SYNOPSIS ✨

int dev_pm_qos_update_user_latency_tolerance (struct device *dev , s32
       val );

🎀 ARGUMENTS 🎀

• dev — the device you're updating the user space latency tolerance for. Like, the main character device in question. 💅
• val — the new user space latency tolerance for dev (and bestie, negative values disable it, okurrr). 🦋
