💖 cti_get_port_type_xr17v35x(9) 💖

okay so this is the Kernel API Manual page for cti_get_port_type_xr17v35x(9) — yes, the title is a whole mouthful, but she's iconic and we're gonna get through it together. 🫶

🌸 NAME 🌸

cti_get_port_type_xr17v35x — read port type from the EEPROM. That's the function's whole little mission: it reads the port type. From the EEPROM. Slay. ✨

✨ SYNOPSIS ✨

enum cti_port_type cti_get_port_type_xr17v35x (struct exar8250 *priv ,
struct pci_dev *pcidev , unsigned int port_num );

🎀 ARGUMENTS 🎀

• priv — the device's private structure. Her little private stash of info. 💅
• pcidev — pointer to the PCI device for this port. Like a little name tag for the port's PCI device. 🎀
• port_num — port offset. Which port we're looking at, basically. 🔍

🦋 DESCRIPTION 🦋

CTI XR17V35X based cards have the port types stored in the EEPROM. This function reads the port type for a single port. That's it, that's the vibe: one port, one read, port type acquired. No cap. 💖

💅 RETURN 💅

• port type on success
• CTI_PORT_TYPE_NONE on failure

So if it ate, you get the port type. If it didn't, you get CTI_PORT_TYPE_NONE. 😭
