STRUCT MSM_GEM_VMA(9)

💅 struct msm_gem_vma(9) 💅

okay bestie, welcome to the Kernel API Manual — this one's a little struct called struct msm_gem_vma and it's literally just a VMA mapping. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

struct msm_gem_vma {
    struct drm_gpuva base;
    struct drm_mm_node node;
    bool mapped;
 };

no cap, that's the entire shape of it 🦋

🌸 Members 🌸

• base — this one inherits from drm_gpuva, so it's giving main character energy from its parent struct 💅
• node — the mm node for VA allocation. that's the whole job.
  • lowkey important: this is only used by kernel managed VMs, so don't come for it if you're doing your own VM thing 🙈
• mapped — the vibe check of the struct tbh: is this VMA mapped? bool, so it's a yes or a no, no in-between 😤

🦋 Description 🦋

so what is it? it represents a combination of a GEM object plus a VM. that's it, that's the whole concept. iconic honestly ✨

okay that's the whole page, you ate that 💖 this little render came from ./drivers/gpu/drm/msm and it's dated October 2026 — go be the main character of your own VMA mapping bestie 🌈⭐
