get_next_vm_bo_from_list(9)

💅 get_next_vm_bo_from_list 💅

okay bestie, this page is from the Kernel API Manual, and it’s giving “tiny helper, huge lockless-iteration energy” ✨

✨ NAME ✨

get_next_vm_bo_from_list — get the next vm_bo element 💖

🎀 SYNOPSIS 🎀

get_next_vm_bo_from_list (__gpuvm , __list_name , __local_list ,
       __prev_vm_bo );

🌸 ARGUMENTS 🌸

• __gpuvm — the drm_gpuvm
• __list_name — the name of the list we’re iterating on
• __local_list — a pointer to the local list used to store already iterated items
• __prev_vm_bo — the previous element we got from get_next_vm_bo_from_list

🦋 DESCRIPTION 🦋

This helper exists to give you lockless list iteration. “Lockless” here means the iterator releases the lock immediately after picking the first element from the list — so list insertion and deletion can happen concurrently. No cap.

Elements popped from the original list are kept in a local list, so removal and is_empty checks can still happen while we’re iterating the list. Iconic behavior, honestly.
