STRUCT CPU_PM_OPS(9)

✨ struct cpu_pm_ops(9) ✨

okay bestie, so like, this is from the Kernel API Manual and it's literally all about the struct cpu_pm_ops which is giving major CPU power management energy 💅

🌸 SYNOPSIS 🌸

like, here's the whole vibe of the struct, no cap:

struct cpu_pm_ops {
    int (*finish_suspend)(unsigned long cpu_state);
    void (*resume)(void);
    void (*scu_prepare)(unsigned int cpu_id, unsigned int cpu_state);
    void (*hotplug_restart)(void);
 };

💖 Members 💖

• finish_suspend — okay so this is the CPU suspend finisher function pointer, like it literally wraps up the suspend shenanigans 🎀
• resume — this one's the CPU resume function pointer, the main character that brings the CPU back to life ✨
• scu_prepare — CPU Snoop Control program function pointer, iykyk 🦋
• hotplug_restart — CPU restart function pointer, the one that says "bestie we're going again" 🔥

🎀 Description 🎀

so basically this structure is holding all the function pointers for CPU low power operations — think suspend, resume and scu programming. it's literally the whole lowkey vibe of keeping your CPU chill but functional, periodt 💜
