✨ atiixp_bmdma_stop(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this little cutie lives in the atiixp corner of the kernel and honestly? she's short, she's sweet, she's iconic. let's get into it 🎀

🌸 NAME 🌸

atiixp_bmdma_stop — the DMA stop callback, no cap 💖

🦋 SYNOPSIS 🦋

void atiixp_bmdma_stop (struct ata_queued_cmd *qc );

like yes, that's the whole signature, she's not doing extra credit 😭

🍓 ARGUMENTS 🍓

• qc — the command that's currently in progress, aka the main character of this whole situation 👑

🌈 DESCRIPTION 🌈

so the DMA has completed, bestie — it's done, it ate, it's leaving the group chat ✨ now we gotta clear the UDMA flag, because the next operations are gonna be PIO ones, not UDMA data transfer. it's giving "different era, different vibe" 💫 periodt.

💀 NOTE 💀

the host lock held by the libata layer is literally our bodyguard 🫶 it protects us from two channels both trying to set DMA bits at the same time — like two besties reaching for the same iced coffee at once 🙈 not on her watch, fr fr.
