madvise_rang...invalidation(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual — this is the madvise_rang...invalidation(9) page, and we're about to make madvise_range_needs_invalidation make sense. it's giving “check whether madvise needs invalidation” and honestly? iconic little helper energy 💅

✨ SYNOPSIS ✨

the whole signature is right here, no cap:

bool madvise_range_needs_invalidation (const struct drm_xe_madvise *args
       );

🌸 ARGUMENTS 🌸

• args — the madvise ioctl arguments. yes bestie, that's the whole argument list. slay.

🦋 DESCRIPTION 🦋

okay so purgeable state updates are lowkey chill: they only touch the VMA/BO metadata. the PTEs stay valid, and they get zapped only if the BO is later purged. that's the whole tea ☕ — no early PTE zapping happening here.

so this function is literally doing the vibe check on whether the update needs PTE invalidation. periodt.

🎀 RETURN 🎀

you get true when the update needs PTE invalidation. that's the result, bestie ✅
