STRUCT EXTCON_CABLE(9)

✨ NAME ✨

okay so bestie, welcome to the struct extcon_cable(9) page from the Kernel API Manual 💖 and no cap, this one is literally struct extcon_cable — “An internal data for an external connector.” It’s giving internal backstage-pass energy for an external connector, and we respect it 💅

🦋 SYNOPSIS 🦋

here’s the whole struct, copy-pasted into our group chat with love and zero typos tolerated:

struct extcon_cable {
    struct extcon_dev *edev;
    int cable_index;
    struct attribute_group attr_g;
    struct device_attribute attr_name;
    struct device_attribute attr_state;
    struct attribute *attrs[3];
    union extcon_property_value usb_propval[EXTCON_PROP_USB_CNT];
    union extcon_property_value chg_propval[EXTCON_PROP_CHG_CNT];
    union extcon_property_value jack_propval[EXTCON_PROP_JACK_CNT];
    union extcon_property_value disp_propval[EXTCON_PROP_DISP_CNT];
    unsigned long usb_bits[BITS_TO_LONGS( EXTCON_PROP_USB_CNT)];
    unsigned long chg_bits[BITS_TO_LONGS( EXTCON_PROP_CHG_CNT)];
    unsigned long jack_bits[BITS_TO_LONGS( EXTCON_PROP_JACK_CNT)];
    unsigned long disp_bits[BITS_TO_LONGS( EXTCON_PROP_DISP_CNT)];
 };

• edev — the extcon device. that’s the whole vibe anchor, fr fr 🌸
• cable_index — the index of this cable in the edev. like its little seat number in the extcon device 💺
• attr_g — the attribute group for the cable. iconic sysfs grouping behavior ✨
• attr_name — the "name" sysfs entry. yes bestie, that exact name 👑
• attr_state — the "state" sysfs entry. and that exact state 🎀
• attrs — the array pointing to attr_name and attr_state for attr_g. it’s the friend group linking them together 🫶
• usb_propval — the array of USB connector properties. USB but make it property-array 💅
• chg_propval — the array of charger connector properties. charger lore 🔋
• jack_propval — the array of jack connector properties. jack behavior, noted 🎧
• disp_propval — the array of display connector properties. display properties serving looks 🌈
• usb_bits — the bit array of the USB connector property capabilities. capability bits, but USB-coded ⭐
• chg_bits — the bit array of the charger connector property capabilities. charger capability bits, slay 🔥
• jack_bits — the bit array of the jack connector property capabilities. jack capability bits, periodt 🦋
• disp_bits — the bit array of the display connector property capabilities. display capability bits, no cap 💜

byeee bestie, this lil page came from ./drivers/extcon, dated October 2026, and it’s literally the struct extcon_cable(9) manual page — mwah, stay iconic 💋💖
