STRUCT HL_USER_INTERRUPT(9)

💅 struct hl_user_interrupt 💅

okay so welcome to the struct hl_user_interrupt(9) page from the Kernel API Manual, bestie. This struct is literally the holder of user interrupt information, and we are about to go through it field by field with the energy it deserves. 🫶

✨ NAME ✨

struct hl_user_interrupt — holds user interrupt information. periodt. 💖

🌸 SYNOPSIS 🌸

struct hl_user_interrupt {
    struct hl_device                *hdev;
    struct hl_ts_free_jobs          ts_free_jobs_data;
    enum hl_user_interrupt_type     type;
    struct list_head                wait_list_head;
    struct list_head                ts_list_head;
    spinlock_t wait_list_lock;
    spinlock_t ts_list_lock;
    ktime_t timestamp;
    u32 interrupt_id;
 };

🎀 Members 🎀

• hdev — pointer to the device structure. iconic pointer behavior, no notes. 👑
• ts_free_jobs_data — timestamp free jobs related data. yes, that is the whole vibe of this field. 🍓
• type — user interrupt type. it is giving “what kind of user interrupt are we dealing with?” energy. 🦋
• wait_list_head — head to the list of user threads pending on this interrupt. the waiting room, basically. 🫶
• ts_list_head — head to the list of timestamp records. timestamp records live here, periodt. ⭐
• wait_list_lock — protects wait_list_head. lock it up, bestie. 🔒
• ts_list_lock — protects ts_list_head. same protective energy, different list. 💅
• timestamp — last timestamp taken upon interrupt. literally the most recent timestamp moment. ⏰
• interrupt_id — msix interrupt id. that is the id, no cap. 🎀
