sil680_selreg(9)

🎀 NAME 🎀

okay so bestie, this is sil680_selreg(9) from the Kernel API Manual, and its whole NAME-line flex is: return register base. 💅

✨ SYNOPSIS ✨

int sil680_selreg (struct ata_port *ap , int r );

🌸 ARGUMENTS 🌸

• ap — the ATA interface. That's the port bestie you're working with, periodt.
• r — the config offset. It's literally the offset into config land, iykyk. 🎀

🦋 DESCRIPTION 🦋

So here's the vibe: this function turns a config register offset into the right address in PCI space, so you can access the control register in question. No cap, that's the whole glow-up. ✨

And thankfully, this is a configuration operation, so it isn't performance critical. Lowkey chill behavior only — fr fr. 🌸
