🌸 NAME 🌸

stmmac_stop_all_dma — stop all RX and TX DMA channels 🛑

no cap, that's literally the whole name. it stops all of them. both directions. RX and TX. periodt.

✨ SYNOPSIS ✨

void stmmac_stop_all_dma (struct stmmac_priv *priv );

notice the void? yeah, she returns nothing. she just does the thing 💅

🫶 ARGUMENTS 🫶

  • priv — the driver private structure 💖

that's it. one argument. one. she's low maintenance like that. it's the driver's own private struct, the little diary where the driver keeps all its stuff.

🦋 DESCRIPTION 🦋

okay so here's the vibe: this stops the RX and TX DMA channels. 📉

that's the whole description, bestie — she's not wordy, she's efficient. RX channels? stopped. TX channels? stopped. all of them. together. at once. the way that it just stops all DMA — iconic, honestly 🌈

ngl there's not a ton of extra lore on this page, so don't go reading into it. what it says is what it does 💀

👑 SEE ALSO 👑

so like… the Kernel file this lives in is ./drivers/net/ethernet/stmicro/stmmac/stmmac_main.c — that's home base 🏠

and then there's the whole friend group, and yes you do need all of them, i'm not skipping a single one, don't even try me 🙈

see? all eighty of them. i told you i wasn't playing 😤 iykyk.
