💅 axienet_dma_bd_release ✨

okay so this is a page from the Kernel API Manual and it's about one very specific little cleanup function, and honestly? she's doing important work. let's get into it 🫶

🌸 NAME 🌸

axienet_dma_bd_release — bestie, this is the one that releases the buffer descriptor rings. that's it, that's the whole job, and she does it flawlessly 💖

🦋 SYNOPSIS 🦋

void axienet_dma_bd_release (struct net_device *ndev );

🎀 ARGUMENTS 🎀

  • ndev — a pointer to the net_device structure. yeah. that's the one. she needs it to know which net device we're cleaning up after, no cap 👑

✨ DESCRIPTION ✨

so here's the tea ☕ — this function is used to release the descriptors that were allocated in axienet_dma_bd_init. like, axienet_dma_bd_init sets the whole thing up, and axienet_dma_bd_release is the friend who helps you pack up the party afterwards 🧹🎀

and when does she get called? axienet_dma_bd_release is called when the Axi Ethernet driver stop api is called. so it's giving cleanup-on-shutdown energy — very responsible, very main character, we love to see it 💅

👑 SEE ALSO 👑

and now, the friend group 💜 — the kernel file lives at ./drivers/net/ethernet/xilinx/xilinx_axienet_main.c, and here is literally everyone she hangs out with:

like, that's the whole group chat right there 😭💀 she knows everybody.

okay that's the page!! this came out of the source tree at ./drivers/net/ethernet/xilinx and it's dated October 2026 — so go forth, release those rings, and slay the cleanup era 🌈⭐💜
