ice_alloc_rx_bufs_zc(9)

💖 ice_alloc_rx_bufs_zc(9) — Kernel API Manual 💖

🌸 NAME 🌸

okay so bestie, ice_alloc_rx_bufs_zc is literally allocate a number of Rx buffers — that’s the whole main character energy of this page. 💅

✨ SYNOPSIS ✨

bool ice_alloc_rx_bufs_zc (struct ice_rx_ring *rx_ring , struct xsk_buff_pool *xsk_pool , u16 count );

🎀 ARGUMENTS 🎀

• rx_ring — the Rx ring, bestie. That’s the ring we’re working with. 🫶
• xsk_pool — the XSK buffer pool to pick buffers to be filled by HW. Hardware does the filling, not us — iconic division of labor. ✨
• count — the number of buffers to allocate. Like, how many are we grabbing? This many. 💖

🦋 DESCRIPTION 🦋

okay so real talk: this is a wrapper for internal allocation routine — it’s giving “middle manager with excellent vibes.” It figures out how many tail bumps should take place based on the given threshold. Lowkey very specific, highkey important. 🌈

It returns true if all calls to internal alloc routine succeeded — so if everything went off without a hitch, you get that true, no cap. 🔥
