drm_gpusvm_for_each_range(9)

💅 drm_gpusvm_for_each_range(9) — like, the whole kernel API manual vibe

okay so bestie, welcome to the drm_gpusvm_for_each_range(9) page ✨ this is the one from the Kernel API Manual, and it's literally all about looping over your GPU SVM ranges inside a notifier. no cap, it's a macro. let's get into it 🫶

---

🌸 NAME 🌸

drm_gpusvm_for_each_range — iterate over GPU SVM ranges in a notifier 💫

---

✨ SYNOPSIS ✨

drm_gpusvm_for_each_range (range__ , notifier__ , start__ , end__ );

---

🎀 ARGUMENTS 🎀

• range__ — the iterator variable for the ranges, iykyk. if it's set, that means it's the start of the iterator. if it's NULL, then the macro calls drm_gpusvm_range_find to go get the range for you 💖
• notifier__ — pointer to the GPU SVM notifier 👑
• start__ — start address of the range ⭐
• end__ — end address of the range 🌈

---

🦋 DESCRIPTION 🦋

so this macro is the one you use to iterate over GPU SVM ranges in a notifier. that's the whole glow-up 🤩

and here's the part that lowkey matters: it is safe to use while holding the driver SVM lock or the notifier lock. both. either. you're covered 💅✨

fr fr, remember that safety line — that's the whole reason this macro exists, bestie.
