STRUCT FW_ERR_INFO(9)

💅 struct fw_err_info(9) — Kernel API Manual ✨

okay bestie, welcome to the <struct fw_err_info(9)> page from the Kernel API Manual. This is the struct that holds FW error information, and it is lowkey giving kernel-tea. 🫖💖

🎀 NAME

struct fw_err_info — FW error information. That’s the whole vibe. ✨

📜 SYNOPSIS

struct fw_err_info {
    struct hl_info_fw_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 FW event was discovered for the first time after the driver has finished booting-up. rn we assume that only fatal events (the ones that require hard-reset) are reported, so we don’t care about the others that might follow it. so once it changes to 1, it will remain that way. TODO: support multiple events. 💀✨
• event_info_available — indicates that a HW event info is now available. 🦋
