map__objdump_2mem(9)

✨ map__objdump_2mem(9) ✨

okay bestie, this one lives in the Kernel API Manual and honestly? it's a little translator fairy 🧚 that speaks both objdump and memory. let's get into it 💅

---

🌸 NAME 🌸

map__objdump_2mem — the glow-up that turns an objdump address into a memory address, no cap 💖

---

🦋 SYNOPSIS 🦋

u64 map__objdump_2mem (const struct map *map , u64 ip );

---

🎀 ARGUMENTS 🎀

• map — the memory map, aka the vibe check context you're working inside 🗺️
• ip — the objdump address you wanna convert, the main character of this whole function ⭐

---

💜 DESCRIPTION 💜

so this function is closely related to map__rip_2objdump — like, siblings, same energy, opposite directions 🔁. what it does is take an address that came out of objdump and convert it into a memory address. translation service, but make it kernel 🫶

⚠️ heads up bestie: this assumes that map actually contains the address. it's not out here verifying anything for you, it's just doing the math. so if you're not sure the map really covers it, don't just trust it blindly 🙈

and if you wanna be sure the result is valid? you check it forwards, like this:

map__rip_2objdump(map__map_ip(map, map__objdump_2mem(map, ip))) == ip

if that round-trips back to ip, you're golden ✨ slay.

---

🔥 RETURN 🔥

the memory address 💫 that's it, that's the whole return value, no surprises, we love a straightforward queen 👑

later bestie!! this little page came from ./tools/perf/util, dated October 2026, and it's literally titled map__objdump_2mem(9) — mwah, go convert some addresses 💖🎀🦋
