💖 resume_target_kernel(9) 💖

okay bestie, welcome to the Kernel API Manual — today's main character is resume_target_kernel(9), and she's here to bring your hibernation image back online. no cap, this is the "we're so back" moment 🫶✨

🌸 NAME 🌸

resume_target_kernel — Restore system state from a hibernation image. literally the restore-from-hibernation glow-up 💅

✨ SYNOPSIS ✨

int resume_target_kernel (bool platform_mode );

🎀 ARGUMENTS 🎀

• platform_mode — whether or not to use the platform driver. that's the whole vibe check for this arg, bestie 💖

🦋 DESCRIPTION 🦋

so here's the tea: resume_target_kernel executes device drivers' "noirq" and "late" freeze callbacks, restores the contents of highmem that have not been restored yet from the image, and runs the low-level code that will restore the remaining contents of memory and switch to the just restored target kernel. it's giving "wake up, we're switching to the target kernel" 😭🔥
