💅 hpt3x3_freeze(9) — Kernel API Manual, bestie edition 💅

okay so this is the page for hpt3x3_freeze, straight from the Kernel API Manual, and it's lowkey a tiny but crucial little function. no cap.

✨ NAME ✨

hpt3x3_freeze — DMA workaround

🌸 SYNOPSIS 🌸

void hpt3x3_freeze (struct ata_port *ap );

🎀 ARGUMENTS 🎀

• ap — the port to freeze. that's the whole vibe: you hand it a struct ata_port * and it's the port getting frozen.

🦋 DESCRIPTION 🦋

When freezing an HPT3x3, you must stop any pending DMA before writing to the control register — otherwise the chip will hang. literally not optional, bestie. stop the pending DMA first, then touch the control register, or it's giving hang city. 😭
