gdb_regs_to_pt_regs(9)

💅 gdb_regs_to_pt_regs(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual, where we take a lil function called gdb_regs_to_pt_regs and explain it like you're my favorite person in the group chat 💖 this one is literally about moving register values from GDB-land into ptrace-land, and it's giving very much "backstage pass between two icons" energy ✨

---

🌸 NAME 🌸

gdb_regs_to_pt_regs — Convert GDB regs to ptrace regs. no cap, that's the whole vibe 🦋

---

⭐ SYNOPSIS ⭐

void gdb_regs_to_pt_regs (unsigned long *gdb_regs , struct pt_regs *regs
);

that's it, that's the signature, screenshot it and put it on your fridge 🫶

---

🎀 ARGUMENTS 🎀

• gdb_regs — a pointer to hold the registers we've received from GDB. like, the lil stash of register values GDB handed over 👑
• regs — a pointer to a struct pt_regs to hold these values in. this is the destination, the final form, the main character 💅

---

✨ DESCRIPTION ✨

so here's what's happening, bestie: it converts the GDB regs sitting in gdb_regs into the pt_regs, and stores them in regs. that's the entire job. the GDB regs get translated into ptrace regs and land in regs. lowkey iconic, highkey necessary 🌈

fr fr, go read the source in ./include/linux before you go poking at regs 💀 i'm just the messenger, bestie.
