pvr_page_table_l2_init(9)

🎀 pvr_page_table_l2_init(9) — Kernel API Manual 🎀

okay so bestie, welcome to the pvr_page_table_l2_init(9) page — yep, that's the function name and the manual section, we love a multitasking icon 💅 this one lives in the Kernel API Manual and honestly? it's giving "small function, big responsibilities" energy ✨

---

🌸 NAME 🌸

pvr_page_table_l2_init — literally just initializes a level 2 page table. that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

int pvr_page_table_l2_init (struct pvr_page_table_l2 *table , struct
pvr_device *pvr_dev );

look at her go 😭 returns an int, takes two pointers, absolutely slays 💖

---

🧚 ARGUMENTS 🧚

• table — the target level 2 page table 🎯 like, the one you're about to bring to life.
• pvr_dev — the target PowerVR device 💜 your main character hardware.

---

🦋 DESCRIPTION 🦋

so here's the thing bestie, and it's lowkey important 🙈 it is expected that table be zeroed before you call this function — like, zeroed as in from kzalloc, okay? kzalloc energy. no cap, don't skip that part, it's not a suggestion, it's what the function expects 😭

---

🔥 RETURN 🔥

• 0 on success 🎉 slay, we love a clean zero.
• any error encountered while intializing table->backing_page using pvr_mmu_backing_page_init 💀 so if that backing page init gets messy, you're getting that error right back, fr fr.

bestie reminder: zero the table first (kzalloc!), or this whole thing is gonna be a bad time 😭 not me warning you twice — it's just that important.

🌸 that's the page!! this little gem comes from ./drivers/gpu/drm/imagination and the version/date on the tin is October 2026 — so yeah, future tech, main character energy, we stan 💜✨🎀
