🎀 ps3_read_ctr(9) — Kernel API Manual energy 🎀

okay so bestie, this is the page for ps3_read_ctr(9) from the Kernel API Manual, and it is short but lowkey iconic. Let's get into it 💅

---

✨ NAME ✨

ps3_read_ctr — Read counter. That's it, that's the whole name section, and honestly? She ate. 💖

---

🌸 SYNOPSIS 🌸

u32 ps3_read_ctr (u32 cpu , u32 ctr );

literally the whole signature, copied exactly, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• cpu — the docs say -- undescribed --, and I'm not gonna invent lore that isn't there. It's giving mystery main character energy 🙈
• ctr — also -- undescribed --. we simply do not know, and the manpage is not elaborating. 💀

---

🔥 DESCRIPTION 🔥

Read 16 or 32 bits depending on the current size of the counter.

Counters 4, 5, 6 & 7 are always 16 bit.

That's the whole vibe check: the read width depends on whatever size the counter is currently rockin', but counters 4, 5, 6, and 7 are always 16 bit. periodt. ⭐
