ata_pci_bmdma_init_one(9)

💖 NAME 💖

okay so bestie, this is the ata_pci_bmdma_init_one(9) page from the Kernel API Manual, and it's literally about how to initialize/register a BMDMA PCI IDE controller. iconic ✨

✨ SYNOPSIS ✨

int ata_pci_bmdma_init_one (struct pci_dev *pdev , const struct
ata_port_info * const * ppi , const struct scsi_host_template *sht ,
void *host_priv , int hflags );

🫶 ARGUMENTS 🫶

• pdev — the controller to be initialized. main character energy fr 💅
• ppi — array of port_info, must be enough for two ports. no shortcuts 🎀
• sht — the scsi_host_template to use when registering the host.
• host_priv — host private_data.
• hflags — host flags.

🌸 DESCRIPTION 🌸

This function is similar to ata_pci_sff_init_one but also takes care of BMDMA initialization. so like, same vibe, extra BMDMA duties 🦋

LOCKING: Inherited from PCI layer (may sleep). so yeah, it may sleep — respect that 😴

🎀 RETURN 🎀

Zero on success, negative on errno-based value on error. that's the whole mood 💀✨
