✨ drm_gpusvm_range_alloc(9) ✨

okay so this is a page from the Kernel API Manual and it's about drm_gpusvm_range_alloc β€” the function that literally makes a GPU SVM range appear out of nowhere and gets it all set up πŸ’… bestie, it's giving "allocator but make it graphics."


🌸 NAME 🌸

drm_gpusvm_range_alloc β€” allocate a GPU SVM range


πŸŽ€ SYNOPSIS πŸŽ€

struct drm_gpusvm_range * drm_gpusvm_range_alloc (struct drm_gpusvm
*gpusvm , struct drm_gpusvm_notifier *notifier , unsigned long
fault_addr , unsigned long chunk_size , bool migrate_devmem );

πŸ’– ARGUMENTS πŸ’–

  • gpusvm β€” a pointer to the GPU SVM structure. this is the whole situation we're working inside 🫢
  • notifier β€” a pointer to the GPU SVM notifier structure
  • fault_addr β€” the fault address. yes, that fault address 😭
  • chunk_size β€” the chunk size
  • migrate_devmem β€” a flag that says whether we should migrate device memory or not

πŸ¦‹ DESCRIPTION πŸ¦‹

this function allocates the GPU SVM range structure and initializes it. both things. in one go. iconic behavior honestly ✨


⭐ RETURN ⭐

on success you get a pointer to the allocated GPU SVM range πŸ’– on failure you get an ERR_PTR. so like… vibe check the return value before you use it, fr fr πŸ™ˆ

okay that's the whole page, no cap πŸ’œ this one lives under ./drivers/gpu/drm, and it's dated October 2026 β€” so like, future era behavior 🌈 and the page itself is drm_gpusvm_range_alloc(9), periodt πŸŽ€ bye bestie, go allocate something responsibly 🧚
