drm_gpusvm_driver_set_lock(9)

💅 drm_gpusvm_driver_set_lock(9) — like, the actual Kernel API Manual, bestie 🎀

okay so picture this: it's drm_gpusvm_driver_set_lock(9), straight outta the Kernel API Manual, and she's here to tell you which lock is guarding the GPU SVM. that's the whole vibe. let's get into it ✨

---

🌸 NAME 🌸

drm_gpusvm_driver_set_lock — she sets the lock that protects accesses to GPU SVM, and honestly? iconic of her 💅

---

⭐ SYNOPSIS ⭐

drm_gpusvm_driver_set_lock (gpusvm , lock );

literally just two args, no cap 🫶

---

🦋 ARGUMENTS 🦋

• gpusvm — a pointer to the GPU SVM structure. that's your girl, she's the whole point 💖
• lock — the lock used to protect the gpuva list. and listen, this one's important: the locking primitive must contain a dep_map field. no dep_map, no deal, periodt 🙈

---

🔥 DESCRIPTION 🔥

so like, you call this to annotate drm_gpusvm_range_find_or_insert and drm_gpusvm_range_remove. that's it. that's the tea ☕ it's giving "lockdep annotation, but make it cute" and we're obsessed 💜

ngl bestie, the one thing to remember here is that dep_map requirement on lock. everything else you can look up. that one you cannot, so don't come for me 😭

okay that's the page!! mwah 💋 this little gem lives in ./include/drm, it's dated October 2026, and it goes by drm_gpusvm_driver_set_lock(9) — stan her, she's a whole main character 🌈⭐🍓
