ps3_reposito...region_count(9)

💅 ps3_reposito...region_count(9) 💅

okay so welcome to the Kernel API Manual, bestie 🎀 and yes the page name is literally truncated with dots — ps3_reposito...region_count(9) — that's just how it's filed, we don't make the rules, we just read them ✨

---

✨ NAME ✨

ps3_repository_read_highmem_region_count — the function that reads the number of highmem regions 🦋 literally that's the whole job, and honestly? iconic for it.

---

🌸 SYNOPSIS 🌸

int ps3_repository_read_highmem_region_count (unsigned int *region_count );

that's it, that's the whole vibe check — an int coming back atcha, and one pointer going in 👑

---

💜 ARGUMENTS 💜

• region_count — okay so the original page literally says -- undescribed -- 😭 which is giving "professor never uploaded the slides". so no cap, there's no description given here. don't come for me, I'm just reporting what's on the page 🙈

---

🔥 DESCRIPTION 🔥

so here's the tea, bestie 🍓 bootloaders must arrange the repository nodes such that regions are indexed with a region_index from 0 to region_count-1.

that's it. that's the whole paragraph. the way that it's short and to the point 💀💅 but like — pay attention, because it says must, which is not a vibe-check suggestion, it's a whole requirement. the bootloader has to lay those nodes out so the indexing runs from 0 up through region_count-1. no gaps, no chaos, no main-character nodes doing their own thing ✨
