STRUCT PVR_FW_LAYOUT_ENTRY(9)

👑 struct pvr_fw_layout_entry — the manual page, but make it make sense 💅

okay so bestie, welcome to the <pink>pvr_fw_layout_entry</pink> glow-up ✨ this is a Kernel API Manual situation, and honestly? it's giving "one little row in a big table" energy. no cap.

---

🌸 NAME 🌸

struct pvr_fw_layout_entry — literally one single entry in the firmware layout table, and what it does is describe a section of the firmware image. that's it. that's the whole vibe. one entry, one section, iconic behavior 🎀

---

✨ SYNOPSIS ✨

here's the shape of it, and yes you have to keep every field exactly like this, no edits, no "improvements", we don't do that here 🫶

struct pvr_fw_layout_entry {
    enum pvr_fw_section_id id;
    enum pvr_fw_section_type type;
    u32 base_addr;
    u32 max_size;
    u32 alloc_size;
    u32 alloc_offset;
 };

---

🦋 Members 🦋

okay this is the part where we meet the cast. six members, all main character energy, let's go 🌈

• id — the section ID. which section is this? this tells you 🪪
• type — the section type. the category, the genre, the ~vibe~ of the section 💫
• base_addr — the base address of the section in FW address space. note that it's FW address space specifically, don't get it twisted 🙈
• max_size — the maximum size of the section, measured in bytes 📏
• alloc_size — the allocation size of the section, also in bytes 💾
• alloc_offset — the allocation offset of the section. where it sits in the allocation 🎯

fr fr: max_size and alloc_size are two different things and both say "bytes" — the manual is very clear on this, so I'm being very clear on this too 💀
