STRUCT HL_INFO_ENGINE_ERR_EVENT(9)

💖 NAME 💖

struct hl_info_engine_err_event — the little struct that's literally just here to spill the tea on engine errors 🛠️✨

okay so real quick — this page lives in the Kernel API Manual, and it's about one single struct. That's it. That's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

struct hl_info_engine_err_event {
    __s64 timestamp;
    __u16 engine_id;
    __u16 error_count;
    __u32 pad;
 };

bestie look at it. four fields. immaculate. no cap. 💅

✨ Members ✨

• timestamp — the time-stamp of when the error happened, i.e. the receipts for exactly when things went sideways 🕐
• engine_id — the engine id of whoever reported the error. snitch behavior, honestly, but we respect it 👀
• error_count — the amount of errors reported. yes it's a count. yes it might be more than one. stay calm 😭
• pad — size padding for u64 granularity. it's giving "filler episode" but it's doing important structural work, don't come for it 🫶

🦋 SEE ALSO 🦋

the whole extended universe lives in the kernel file ./include/uapi/drm/habanalabs_accel.h — go read it, it's the main character 🧚

ngl this struct is short but it ate. every field accounted for, nothing skipped, we love a clean layout 💯
