ata_pci_sff_activate_host(9)

✨ ata_pci_sff_activate_host(9) ✨

from the Kernel API Manual — okay so bestie, this page is all about starting an SFF ATA host, requesting its IRQ(s), and registering it 💅 no cap.

💖 NAME 💖

ata_pci_sff_activate_host — start SFF host, request IRQ and register it.

✨ SYNOPSIS ✨

int ata_pci_sff_activate_host (struct ata_host *host , irq_handler_t
irq_handler , const struct scsi_host_template *sht );

🎀 ARGUMENTS 🎀

• host — target SFF ATA host 🎯
• irq_handler — the irq_handler used when requesting IRQ(s) ⚡
• sht — the scsi_host_template to use when registering the host 📝

🦋 DESCRIPTION 🦋

okay so this is literally the counterpart of ata_host_activate for SFF ATA hosts. the way it needs its own separate helper? iconic, honestly. and it's necessary because SFF hosts use two separate interrupts in legacy mode 🫶

🔒 LOCKING

inherited from the calling layer (may sleep) 😴

🌸 RETURN 🌸

0 on success, -errno otherwise. slay ✨
