drm_pagemap_devmem_init(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

Welcome to drm_pagemap_devmem_init(9) — yes, that's the title, and this lil page lives in the Kernel API Manual. 💅

drm_pagemap_devmem_init — Initialize a drm_pagemap device memory allocation. That's the whole name, no cap. 💖

✨ SYNOPSIS ✨

okay so the signature is literally this, bestie — copy it exactly, no autocorrect:

void drm_pagemap_devmem_init (struct drm_pagemap_devmem
       *devmem_allocation , struct device *dev , struct mm_struct *mm , const
       struct drm_pagemap_devmem_ops *ops , struct drm_pagemap *dpagemap ,
       size_t size , struct dma_fence *pre_migrate_fence );

🎀 ARGUMENTS 🎀

Every arg matters, so let's do a lil vibe check on each one:

  • devmem_allocation — The struct drm_pagemap_devmem to initialize. 💖
  • dev — Pointer to the device structure which device memory allocation belongs to.
  • mm — Pointer to the mm_struct for the address space.
  • ops — Pointer to the operations structure for GPU SVM device memory.
  • dpagemap — The struct drm_pagemap we're allocating from.
  • size — Size of device memory allocation.
  • pre_migrate_fence — Fence to wait for or pipeline behind before migration starts. (May be NULL).
