💖 __init_dma_rx_desc_rings(9) — Kernel API Manual 💖

okay bestie, welcome to the page for __init_dma_rx_desc_rings(9), straight from the Kernel API Manual. it's giving kernel-internals main character energy, and yes we're gonna get through it together 🫶

🌸 NAME 🌸

__init_dma_rx_desc_rings — init the RX descriptor ring (per queue). periodt.

✨ SYNOPSIS ✨

int __init_dma_rx_desc_rings (struct stmmac_priv *priv , struct
stmmac_dma_conf *dma_conf , u32 queue , gfp_t flags );

🎀 ARGUMENTS 🎀

• priv — the driver private structure, aka the driver's own little private struct carrying the tea.
• dma_conf — the structure that takes the DMA data, literally.
• queue — the RX queue index, iykyk.
• flags — the gfp flag. yes, gfp_t energy, no cap.

🦋 DESCRIPTION 🦋

okay so this function initializes the DMA RX descriptors and allocates the socket buffers. it supports the chained and ring modes. that's the whole vibe — descriptors initialized, socket buffers allocated, modes supported. slay 💅
