PROBE::SIGNAL.WAKE(3stap)

✨ PROBE::SIGNAL.WAKE ✨

okay bestie, welcome to the Signal Tapset section of the SystemTap Tapset Reference — this is the page for PROBE::SIGNAL.WAKE(3stap) and it's literally all about that moment when a sleepy little process gets poked awake because a signal came knocking 🫶

---

🌸 NAME 🌸

probe::signal.wakeup — the probe for when a sleeping process is being wakened for a signal 💤➡️👀

---

✨ SYNOPSIS ✨

probe signal.wakeup {}

that's it. that's the whole vibe. no arguments, no fancy parameters, just a probe sitting there waiting for a process to wake up. iconic behavior honestly 🎀

---

💖 VALUES 💖

these are the local variables you get to peek at inside the probe. read them like a little group chat, each one is spilling something different 👑

• resume — tells you whether the task is getting woken up while it's in a STOPPED or TRACED state. basically: is this a normal nap wake-up or a weird one 👀
• sig_pid — the PID of the process that's getting woken up. the number, the whole number, nothing but the number 🔢
• state_mask — a string that shows the mask of task states that are allowed to be woken. the possible values are TASK_INTERRUPTIBLE, TASK_STOPPED, TASK_TRACED, TASK_WAKEKILL, and TASK_INTERRUPTIBLE. yes, TASK_INTERRUPTIBLE is in that list twice — that's exactly how the original lists it and I'm not about to ghost one of them, so here it is twice, fr fr 💅
• pid_name — the name of the process to wake. the cute little string version, for when you don't wanna squint at a number 🌸

lowkey obsessed with how tidy this page is. four values, one probe, zero drama. main character energy fr 💜
