STRUCT PANTHOR_GEM_BACKING(9)

💖 struct panthor_gem_backing(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — we're deep in the kernel girlie trenches today and honestly? it's giving iconic. this page is all about struct panthor_gem_backing, which is literally the GEM memory backing related data ✨ no cap, that's the whole vibe.

🎀 SYNOPSIS 🎀

here's the whole struct, laid out exactly, don't touch a character of it:

struct panthor_gem_backing {
    struct page **pages;
    refcount_t pin_count;
};

two members, that's it, that's the queen 👑 lowkey obsessed with how clean that is.

🌸 Members 🌸

• pages — these are the pages that got requested with drm_gem_get_pages. that's the actual memory backing right there, the whole point of the struct fr fr 🫶
• pin_count — a refcount_t that tracks the number of active pin requests on this GEM. so like, how many people currently have this thing pinned down. tracking the headcount at the door 💅
