🎀 drm_can_sleep(9) 🎀

okay so welcome to the Kernel API Manual page for drm_can_sleep, bestie 💖 this one is short but it has opinions.

🌸 NAME 🌸

drm_can_sleep — returns true if it’s currently okay to sleep 😴

✨ SYNOPSIS ✨

bool drm_can_sleep (void );

🎀 ARGUMENTS 🎀

  • void — no arguments. literally none. zero. the void is voiding 🫶

💅 DESCRIPTION 💅

okay so real talk: This function shall not be used in new code. periodt. do not put this in your new code, bestie, i am begging 🙈

the check for running in atomic context may not work — see linux/preempt.h for the details 👀

FIXME: All users of drm_can_sleep should be removed (see todo.rst) 💀

so yeah. it’s giving “legacy icon but also please retire her gently.” no cap.

🔥 RETURN 🔥

False if kgdb is active, we are in atomic context or irqs are disabled. that’s the vibe check it’s doing 😭
