xe_vm_bump_lru(9)

xe_vm_bump_lru(9) — hiiii bestie, welcome to the Kernel API Manual page for LRU bumping, and yes we're gonna make it make sense 💅✨

🎀 NAME 🎀

xe_vm_bump_lru — bump the LRU position of BOs used by a submission, periodt.

✨ SYNOPSIS ✨

void xe_vm_bump_lru (struct xe_vm *vm , struct drm_exec *exec );

🫶 ARGUMENTS 🫶

• vm — the vm for which we are bumping LRUs. That's the whole assignment, bestie 🫡
• exec — the struct drm_exec with the locked GEM objects. Locked GEMs stay locked, iykyk 🔒

💖 DESCRIPTION 💖

Okay so here's the vibe: this moves the VM's private BOs, plus all external objects locked by exec, over to the LRU tail. The private BOs get moved in bulk using the vm's xe_vm.lru_bulk_move — bulk move, iconic ✨

The external objects are a different story. They may be shared with other VMs, so they're not part of that bulk move, and they get bumped individually instead. No cap, that's the whole function.
