mv_port_stop(9)

🎀 mv_port_stop(9) — Kernel API Manual 🎀

🌸 NAME 🌸

mv_port_stop — Port specific cleanup/stop routine. That’s the whole assignment, bestie: the port-specific cleanup and stop moment. 💅

✨ SYNOPSIS ✨

void mv_port_stop (struct ata_port *ap );

🦋 ARGUMENTS 🦋

• ap — ATA channel to manipulate. This is the ATA channel you’re manipulating, periodt.

💅 DESCRIPTION 💅

Okay so this routine does exactly what it says: Stop DMA, cleanup port memory. Two little tasks, both real, no cap. It’s giving cleanup era and we’re obsessed. 🧹✨

🔒 LOCKING: This routine uses the host lock to protect the DMA stop. So the host lock is literally on duty for the DMA stop, bestie — that’s the safety vibe. 🫶
