__netmem_get_pp(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for __netmem_get_pp(9). It will unsafely get a pointer to the &page_pool backing @netmem 😭. No cap, unsafe is literally in the name.

✨ SYNOPSIS ✨

struct page_pool * __netmem_get_pp (netmem_ref netmem );

🎀 ARGUMENTS 🎀

• netmem — the netmem reference to get the pointer from 🫶

🦋 DESCRIPTION 🦋

This is the unsafe version of netmem_get_pp. When netmem is always page-backed — e.g. when it's a header buffer — it performs faster and generates smaller object code, because it avoids clearing the LSB ✨.

But bestie, listen: when netmem points to IOV, it provokes invalid memory access 💀. That is the risk. That is the vibe. Do not forget it.

🌸 RETURN 🌸

A pointer to the page_pool — and it's garbage if netmem is not page-backed 😬
