STRUCT MLXREG_HOTPLUG_PRIV_DATA(9)

💅 struct mlxreg_hotplug_priv_data 💅

okay bestie, welcome to the Kernel API Manual page for struct mlxreg_hotplug_priv_data — aka the platform private data struct, and honestly? she's giving quiet main character energy ✨

🌸 NAME 🌸

struct mlxreg_hotplug_priv_data — the platform private data: like, the whole struct, and yes the colon at the end is canon, we don't question the original 😌

🦋 SYNOPSIS 🦋

struct mlxreg_hotplug_priv_data {
    int irq;
    struct device *dev;
    struct platform_device *pdev;
    struct mlxreg_hotplug_platform_data *plat;
    struct regmap *regmap;
    struct delayed_work dwork_irq;
    spinlock_t lock;
    struct device *hwmon;
    struct attribute *mlxreg_hotplug_attr[MLXREG_HOTPLUG_ATTRS_MAX + 1];
    struct sensor_device_attribute_2
mlxreg_hotplug_dev_attr[MLXREG_HOTPLUG_ATTRS_MAX];
    struct attribute_group group;
    const struct attribute_group *groups[2];
    u32 cell;
    u32 mask;
    u32 aggr_cache;
    bool after_probe;
    u8 not_asserted;
 };

(yes the mlxreg_hotplug_dev_attr line wraps like that in the original — we do not edit the queen's outfit 💅)

👑 Members 👑

• irq — the platform device interrupt number, like the doorbell number for this device fr fr 🔔
• dev — the basic device, the plain one, the foundation bestie 🫶
• pdev — the platform device, its more specific sibling ✨
• plat — the platform data, all the config vibes 🎀
• regmap — the register map handle, your little key to the registers 🔑
• dwork_irq — a delayed work template, scheduling things for later, very "i'll deal with it tmrw" 😭
• lock — a spin lock, protecting the goods ⭐
• hwmon — the hwmon device, hardware monitoring representation 🌡️
• mlxreg_hotplug_attr — the sysfs attributes array 📋
• mlxreg_hotplug_dev_attr — the sysfs sensor device attribute array, the fancy sensor-flavoured one 🌈
• group — a sysfs attribute group, vibes grouped together for convenience 🧚
• groups — the list of sysfs attribute group for hwmon registration, yes plural, yes for hwmon 👀
• cell — location of top aggregation interrupt register, the coordinate of the big one 📍
• mask — top aggregation interrupt common mask, the shared filter 🎭
• aggr_cache — last value of aggregation register status, like a screenshot of the register's previous mood 📸
• after_probe — flag indication probing completion, did the probe finish or not, the plot twist marker 🔥
• not_asserted — number of entries in workqueue with no signal assertion, literally a count of queue entries chilling without their signal 💀

🍓 SEE ALSO 🍓

• Kernel file ./drivers/platform/mellanox/mlxreg-hotplug.c — go read the source, iykyk 📖

and that's the whole page diva 💖 no cap, that's every member, every type, every array bound — MLXREG_HOTPLUG_ATTRS_MAX + 1 and MLXREG_HOTPLUG_ATTRS_MAX and groups[2] all accounted for 👑

later bestie ~ this cutie came from ./drivers/platform/mellanox, dated October 2026, and it's filed under struct mlxreg_hotplug_priv_data(9) in the Kernel API Manual 🎀💜
