STRUCT PSERIES_SUSPEND_INFO(9)

🦋 struct pseries_suspend_info 🦋

okay bestie, welcome to the Kernel API Manual page for struct pseries_suspend_info 💖 this one is literally the state shared between CPUs for join/suspend, and it’s giving “small struct, big responsibilities” energy ✨

🌸 NAME 🌸

struct pseries_suspend_info — state shared between CPUs for join/suspend 🫶

🎀 SYNOPSIS 🎀

struct pseries_suspend_info {
    atomic_t counter;
    bool done;
 };

💅 Members 💅

• counter — bestie, threads are to increment this upon resuming from suspend or if an error is received from H_JOIN. The thread which performs the first increment (i.e. sets it to 1) is responsible for waking the other threads 👑
• done — False if join/suspend is in progress. True if the operation is complete (successful or not). no cap, that’s the whole vibe check 💀
