STRUCT PANTHOR_VMA(9)

💅 struct panthor_vma(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual entry for struct panthor_vma(9) — it's giving GPU mapping object, and honestly? iconic. let's get into it ✨

---

✨ NAME ✨

struct panthor_vma — the GPU mapping object. that's it, that's the vibe. 🦋

---

🌸 SYNOPSIS 🌸

struct panthor_vma {
    struct drm_gpuva base;
    struct list_head node;
    u32 flags;
    bool evicted;
 };

like, look at her. four fields, zero notes. main character energy fr fr 👑

---

🎀 Members 🎀

• base — she inherits from drm_gpuva. nepo baby but make it struct inheritance, yk? 💖
• node — this one's whole job is to implement deferred release of VMAs. lowkey the cleanup crew of the struct. 🧹
• flags — a combination of drm_panthor_vm_bind_op_flags. heads up though: only map related flags are accepted. so don't go throwing random flags in there and acting surprised, bestie 😭
• evicted — a bool that's true if the VMA has been evicted. she's been through it. 💀

---

🦋 Description 🦋

this struct is what we use to track GEM mappings in GPU space. that's the whole thesis. no cap. 🔥

ok that's the whole page, go read the source too, i'm not your mom 💜

and that's a wrap, bestie!! this one came from ./drivers/gpu/drm/panthor, part of the Kernel API Manual, dated October 2026, filed under struct panthor_vma(9). slay, bye!! 🌈⭐💅
