✨ eeh_token_to_phys(9) ✨

okay so real talk, we're deep in the Kernel API Manual rn and this page is genuinely a little one — like, one function, one job, one vibe. it is eeh_token_to_phys and she is here to do exactly what her name says 💅

---

🌸 NAME 🌸

eeh_token_to_phys — convert EEH address token to phys address

like. that's it. that's the whole arc. and honestly? iconic 🎀

---

🦋 SYNOPSIS 🦋

unsigned long eeh_token_to_phys (unsigned long token );

yes bestie, that trailing space before the ) is real, it's in the original, do not come for me 🙈 copy it exactly if you're copying it.

---

💖 ARGUMENTS 💖

• token — the I/O token, and per the manpage it should be an address in the form 0xA.... — so like, it's giving hex, it's giving 0xA prefix, that's the shape you're handing over 🫶

---

⭐ DESCRIPTION ⭐

so the whole point: this routine should be called to convert a virtual I/O address to a physical one. that's the assignment. that's the function. no cap, no extra steps, no secret side quests listed here 💜

bestie note: the manpage says should be called and says the token should be in the 0xA.... form — that's the documented expectation, so don't be out here improvising arguments and then acting surprised, okay? 😭
