STRUCT ARCH_HIBERNATE_HDR(9)

💖 NAME 💖

okay so welcome to the struct arch_hibernate_hdr(9) page in the Kernel API Manual — this is literally the struct of helper parameters that help us to restore the image. it's giving helper-params energy, no cap. periodt. ✨

🦋 SYNOPSIS 🦋

vibe check, bestie — here's the shape of it, exact and untouched:

struct arch_hibernate_hdr {
    struct arch_hibernate_hdr_invariants invariants;
    unsigned long   hartid;
    unsigned long   saved_satp;
    unsigned long   restore_cpu_addr;
};

🎀 Members 🎀

lowkey every member below is iconic main character work, so slay, let's go one by one:

• invariants — a container to store the kernel build version. 🧚
• hartid — makes sure the same boot_cpu executes the hibernate/restore code. 🔥
• saved_satp — the original page table used by the hibernated image. 🦋
• restore_cpu_addr — the kernel's image address to restore the CPU context. 💜

bestie, highkey this struct is literally the helper-params container for restoring the image — every member above matters, so don't skip any 💅
