STRUCT MLXREG_CORE_DATA(9)

💖 NAME 💖

okay bestie, this page is struct mlxreg_core_data(9) from the Kernel API Manual, and the NAME is literally struct mlxreg_core_data - attributes control data: no cap, that’s the whole vibe.

✨ SYNOPSIS ✨

here’s the exact struct, copied with love and zero editing:

struct mlxreg_core_data {
    char label[MLXREG_CORE_LABEL_MAX_SIZE];
    u32 reg;
    u32 mask;
    u32 bit;
    u32 capability;
    u32 reg_prsnt;
    u32 reg_sync;
    u32 reg_pwr;
    u32 reg_ena;
    umode_t mode;
    struct device_node *np;
    struct mlxreg_hotplug_device hpdev;
    struct mlxreg_core_hotplug_notifier *notifier;
    u32 health_cntr;
    bool attached;
    u8 regnum;
    u8 slot;
    u8 secured;
};
