STRUCT DRM_PVR_HEAP(9)

✨ struct drm_pvr_heap(9) ✨

okay so bestie, welcome to the Kernel API Manual page for struct drm_pvr_heap — yes the manual name is literally Kernel API Manual, and the star of the show is this little struct. she's a container holding information about a single heap 💅 and she's lowkey iconic for it.

---

🎀 NAME 🎀

struct drm_pvr_heap — the container holding information about a single heap. periodt.

---

🦋 SYNOPSIS 🦋

struct drm_pvr_heap {
    __u64 base;
    __u64 size;
    __u32 flags;
    __u32 page_size_log2;
 };

---

💖 Members 💖

• base — the base address of the heap. like, where the heap starts living rent-free ✨
• size — the size of the heap, in bytes. and listen, if the heap isn't present, this will be 0. so a zero here is literally the "no thoughts, head empty" vibe check 🙈
• flags — the flags for this heap. currently always 0. no cap, that's just how it is.
• page_size_log2 — the log2 of the page size. it's giving "we do exponents here" 🧚

---

🌸 Description 🌸

this will always be fetched as an array. not one, not two — an array, bestie. every single time. 🔥
