💅 ps3_repository_read_boot_dat_info(9) 💅

okay bestie, so this one's from the Kernel API Manual (yes, that Kernel API Manual, the one we all know and love 🫶) and it's lowkey iconic. we're in the ps3 corner of the kernel, and this little function is here to hand you the address and the size of cell_ext_os_area. that's the whole vibe check. short, sweet, slays. ✨

🌸 NAME 🌸

ps3_repository_read_boot_dat_info — get address and size of cell_ext_os_area. periodt. 💖

---

✨ SYNOPSIS ✨

int ps3_repository_read_boot_dat_info (u64 *lpar_addr , unsigned int
*size );

like, it takes two pointers and returns an int. not me obsessing over such a clean little signature 😭

---

🎀 ARGUMENTS 🎀

• lpar_addr — the lpar address of cell_ext_os_area, fr fr. that's the address part of the whole situation. 📍
• size — the size of cell_ext_os_area. bestie we're literally getting the size. no cap. 📏

both of these are pointers, so the function is writing back out through them. keep that in mind and you'll be fine 💅
