💅 amdgpu_vm_bo_needs_update(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is short but lowkey important, so stay with me 🫶

🌸 NAME 🌸

amdgpu_vm_bo_needs_update — vm_bo needs pagetable update. that's it, that's the whole vibe check 💅

✨ SYNOPSIS ✨

void amdgpu_vm_bo_needs_update (struct amdgpu_vm_bo_base *vm_bo );

like, you hand it a vm_bo and it just... marks the tea ☕ no return value, we don't do that here.

🎀 ARGUMENTS 🎀

  • vm_bo — the vm_bo which is out of date 🙈 like it's literally the one whose page tables are living in the past, main character energy but make it stale.

💖 DESCRIPTION 💖

so this is the state for vm_bo objects that means the underlying BO had mapping changes — think a move, or a PRT bind/unbind — but the new location is not yet reflected in the page tables. 🫠

basically: the tea has changed, but the page tables haven't heard about it yet. not me calling out stale mappings 😭 it's giving "read receipts off".
