tee_shm_get_pa(9)

💅 tee_shm_get_pa(9) — like, the Kernel API Manual glow-up

okay so bestie, welcome to tee_shm_get_pa(9) — yes, that's the manual page name, section 9, from the Kernel API Manual, and no I will not be normal about it 🫶

---

✨ NAME ✨

tee_shm_get_pa — literally just: get the physical address of a shared memory, plus an offset. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int tee_shm_get_pa (struct tee_shm *shm , size_t offs , phys_addr_t *pa
);

she takes three things and gives you back an int. short, sweet, iconic 👑

---

🦋 ARGUMENTS 🦋

• shm — the shared memory handle, aka your main character. it's a struct tee_shm *.
• offs — offset from the start of this shared memory. a size_t, bestie, so keep it unsigned and keep it sensible 🌈
• pa — the physical address to return. it's a phys_addr_t *, so you're handing over a pointer and letting her fill it in. she returns 0 if offs is within the bounds of this shared memory — and if it's not, you get an error code instead. vibe check failed, sorry 😭

fr fr the only thing you're getting out of this page is a physical address + offset sanity check. no cap. don't invent extra behaviour, she didn't say that 💀
