STRUCT HW_ERR_INFO(9)

💖 struct hw_err_info — Kernel API Manual 💖

okay so welcome to the struct hw_err_info(9) page, bestie! This is the Kernel API Manual moment where we learn about HW error information — no cap, that’s literally what the NAME section says. ✨

✨ NAME ✨

struct hw_err_info — HW error information. 💅

🦋 SYNOPSIS 🦋

struct hw_err_info {
    struct hl_info_hw_err_event     event;
    atomic_t event_detected;
    bool event_info_available;
 };

🫶 Members 🫶

• event — holds information on the event. 🎀
• event_detected — if it’s set as 1, then a HW event was discovered for the first time after the driver has finished booting-up. Currently we assume that only fatal events (that require hard-reset) are reported, so we don’t care about the others that might follow it. So once it’s changed to 1, it will remain that way. TODO: support multiple events. 😭
• event_info_available — indicates that a HW event info is now available. 🦋
