STRUCT PDIV_MAP(9)

💅 struct pdiv_map(9) — the kernel API manual, but make it make sense

okay so bestie, welcome to struct pdiv_map(9) 🌸 this is a lil page from the Kernel API Manual and it's literally the whole personality of a post-divider-to-hardware-value mapping. yes it's small. yes it's iconic. let's get into it 🎀

---

✨ NAME ✨

struct pdiv_map — maps a post divider over to its hw value. that's the whole gig, no cap 🫶

---

✨ SYNOPSIS ✨

struct pdiv_map {
    u8 pdiv;
    u8 hw_val;
 };

look at her. two whole u8 fields. absolute main character energy 💅

---

✨ Members ✨

• pdiv — the post divider itself, bestie. that's the value. the divider. the post one 🦋
• hw_val — the value that's gonna be written to the PLL hw 🔥 that's it, that's the field.

lowkey the tiniest struct in the whole clock tree and she still ate 🍓

okay that's the page!! this one came out of ./drivers/clk/tegra and it's dated October 2026 ⭐ catch you in the next manpage, mwah 💜🧚
