stmmac_dma_interrupt(9)

💖 NAME 💖

hey bestie, welcome to the Kernel API Manual page for stmmac_dma_interrupt(9) — the DMA ISR with main-character energy 💅✨

stmmac_dma_interrupt — DMA ISR. no cap, that’s the whole name 🎀

✨ SYNOPSIS ✨

void stmmac_dma_interrupt (struct stmmac_priv *priv );

🫶 ARGUMENTS 🫶

• priv — driver private structure. it’s the driver’s private little world, and this is the pointer to it 🦋

💅 DESCRIPTION 💅

okay so this is literally the DMA ISR. the main ISR calls it. from there, it calls the dwmac dma routine and it schedules the poll method in case there’s some work that can be done. periodt 💖

🌈 SEE ALSO 🌈

the kernel file is ./drivers/net/ethernet/stmicro/stmmac/stmmac_main.c — yes bestie, that’s the spot 👑
