STRUCT INTEL_TH(9)

✨ struct intel_th(9) ✨

okay so bestie, buckle up 💅 this is a page from the Kernel API Manual and it's all about struct intel_th, which is literally the Intel TH controller. yes. that one. let's get into it 🫶

🌸 NAME 🌸

struct intel_th — Intel TH controller ✨

---

🦋 SYNOPSIS 🦋

struct intel_th {
    struct device           *dev;
    struct intel_th_device  *thdev[TH_SUBDEVICE_MAX];
    struct intel_th_device  *hub;
    const struct intel_th_drvdata   *drvdata;
    struct resource         resource[TH_MMIO_END];
    int (*activate)(struct intel_th *);
    void (*deactivate)(struct intel_th *);
    unsigned int            num_thdevs;
    unsigned int            num_resources;
    int irq;
    int num_irqs;
    int id;
    int major;
  #ifdef CONFIG_MODULES;
    struct work_struct      request_module_work;
  #endif ;
  #ifdef CONFIG_INTEL_TH_DEBUG;
    struct dentry           *dbg;
  #endif;
};

like, yes, that's the whole vibe of the thing 💖 copy it exactly, don't @ me.

🎀 Members 🎀

okay so here's the breakdown of every member, no cap:

• dev — the driver core's device, obvs. it's the device that holds this whole situation together 🫶
• thdev — the subdevices ✨ like, the little guys hanging out inside the controller.
• hub — the "switch" subdevice (GTH). that's literally what the original calls it, quotes and all 👑
• resource — the resources of the entire controller. all of them. the whole resource situation 🔥
• num_thdevs — number of devices in the thdev array. the count. the headcount 💅
• num_resources — number of resources in the resource array. yes, another count. we love a count 🎀
• irq — irq number 🌈
• num_irqs — number of IRQs is use. (that's the original's wording, bestie — "is use", not "in use" — i'm not fixing it, i'm just quoting it 🙈)
• id — this Intel TH controller's device ID in the system. its little name tag at the party 🦋
• major — device node major for output devices. iconic. periodt 💜

ngl the struct also has drvdata, activate, deactivate, request_module_work and dbg chillin' in there — they're right up in the synopsis — but the Members list doesn't spell them out, so neither am i. i said what i said 💀
