xe_mem_pool_insert_node(9)

xe_mem_pool_insert_node(9) 💖

okay bestie, this page is straight from the Kernel API Manual, and it's all about inserting a node into a memory pool. The function name is already giving main character energy, so let's get into it. ✨

🌸 NAME 🌸

xe_mem_pool_insert_node — insert a node into the memory pool 🫶

✨ SYNOPSIS ✨

int xe_mem_pool_insert_node (struct xe_mem_pool *pool , struct
       xe_mem_pool_node *node , u32 size );

🎀 ARGUMENTS 🎀

• pool — the memory pool to insert into. This is the destination, bestie.
• node — the node to insert. Yes, that node.
• size — the size of the node to be allocated, in bytes.

🦋 DESCRIPTION 🦋

So what it does: it inserts a node into the specified memory pool, and it uses drm_mm for allocation. That's the whole vibe. The pool is the place, the node is the thing, and drm_mm handles the allocation part. Lowkey iconic that the description is one sentence, honestly. 💅

🌈 RETURN 🌈

It returns 0 on success 🎉 or a negative error code on failure 😭.
