it821x_port_start(9)

💅 it821x_port_start(9) 💅

okay so bestie, this page is from the Kernel API Manual, and it's literally all about it821x_port_start — the port setup hook. ✨

✨ NAME ✨

it821x_port_start — port setup. That's the whole vibe: setup time, no cap. 🎀

🌸 SYNOPSIS 🌸

int it821x_port_start (struct ata_port *ap );

🦋 ARGUMENTS 🦋

• ap — the ATA port being set up. That's the one and only argument, bestie. 💖

💜 DESCRIPTION 💜

So the it821x needs to maintain private data structures, and it also needs to use the standard PCI interface — but that interface lacks support for this functionality. 😭 The move is: set up the private data on the port start hook, and tear it down on port stop. Cleanup queen behavior, honestly. 🧚
