i915_gem_userptr_invalidate(9)

✨ NAME ✨

okay so bestie, this is the i915_gem_userptr_invalidate(9) page from the Kernel API Manual, and it's literally the callback to notify about mm change. No cap. 💅

🦋 SYNOPSIS 🦋

Here's the exact signature, copy-paste energy:

bool i915_gem_userptr_invalidate (struct mmu_interval_notifier *mni ,
const struct mmu_notifier_range *range , unsigned long cur_seq );

💖 ARGUMENTS 💖

• mni — the range (mm) is about to update. That's the whole vibe.
• range — details on the invalidation. Spill the tea. 🫖
• cur_seq — Value to pass to mmu_interval_set_seq.

🔥 DESCRIPTION 🔥

So what it does: it blocks for operations on BOs to finish, then marks pages as accessed and potentially dirty. Iconic behavior, honestly. 💅

🌸 SEE ALSO 🌸
