libeth_rx_page_pool_params(9)

💖 NAME 💖

okay so this is libeth_rx_page_pool_params(9) from the Kernel API Manual, and it’s literally here to calculate params with the stack overhead ✨

✨ SYNOPSIS ✨

bool libeth_rx_page_pool_params (struct libeth_fq *fq , struct page_pool_params *pp );

🎀 ARGUMENTS 🎀

• fq — the buffer queue you’re calculating the size for, bestie 🫶
• pp — the page_pool_params of the netdev 💅

🦋 DESCRIPTION 🦋

So what it does is set the PP params with all the needed stack overhead — yes, that means headroom and tailroom — plus both the HW buffer length and the truesize for all types of buffers. No cap, it’s giving “full coverage” energy 🌈

For “short” buffers, truesize never exceeds the “wanted” one. For the rest, it can go all the way up to the page size. That’s the vibe check 🔥

🌸 RETURN 🌸

• true on success 👑
• false on invalid input params 💀
