pvr_page_table_l0_init(9)

💅 pvr_page_table_l0_init — level 0 page table glow-up (kernel API manual, section 9) 🎀

okay so bestie, welcome to the manual page for pvr_page_table_l0_init — it lives in the kernel API manual, section 9, and it is literally the "make a level 0 page table exist" moment. let's get into it 🫶

---

✨ NAME ✨

pvr_page_table_l0_init — Initialize a level 0 page table. that's it, that's the vibe 💜

---

🌸 SYNOPSIS 🌸

int pvr_page_table_l0_init (struct pvr_page_table_l0 *table , struct
pvr_device *pvr_dev );

---

🦋 ARGUMENTS 🦋

• table — the target level 0 page table. this is the one getting initialized, she's the main character here 👑
• pvr_dev — the target PowerVR device. the hardware bestie this table belongs to ✨

---

💖 DESCRIPTION 💖

so when this function returns successfully, table is still not considered valid. 😭 like, she exists but she's not ready. she has to be inserted into the page table tree structure with pvr_page_table_l1_insert before she's actually ready for use. no shortcuts, no skipping steps, periodt.

also — and this is important — it is expected that table be zeroed (e.g. from kzalloc) before calling this function. fr fr, zero it first.

---

🔥 RETURN 🔥

• 0 on success, or
• any error encountered while intializing table->backing_page using pvr_mmu_backing_page_init.
