✨ sil680_sff_exec_command(9) ✨

okay so bestie, welcome to the glow-up of the sil680_sff_exec_command(9) page from the Kernel API Manual. This one is short and sweet, but every deet is staying. 💅

🎀 NAME 🎀

sil680_sff_exec_command — issue ATA command to host controller. 💖

🌸 SYNOPSIS 🌸

Here's the signature, copied exactly, no cap:

       void sil680_sff_exec_command (struct ata_port *ap , const struct
       ata_taskfile *tf );

🦋 ARGUMENTS 🦋

• ap — the port to which the command is being issued. 📍
• tf — the ATA taskfile register set. 🗂️

🔥 DESCRIPTION 🔥

So what it does: it issues an ATA command, and it does the proper synchronization with the interrupt handler / other threads. fr fr, no race-y chaos here.

It uses our MMIO space for PCI posting to avoid a hideously slow cycle all the way to the device. Literally saving you from the slowest little travel arc ever. 🐌➡️💨

LOCKING: spin_lock_irqsave(host lock) 🔒
