STRUCT IWL_SYSTEM_STATISTICS_PART1_NOTIF_OPER(9)

💅 struct iwl_system_statistics_part1_notif_oper(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a struct page and honestly it's giving "underrated backstage pass to the firmware stats show" ✨

---

🌸 NAME 🌸

struct iwl_system_statistics_part1_notif_oper — the part1 stats notification. that's it, that's the whole vibe. it's the little notification blob that carries the first chunk of system statistics 🎀

---

✨ SYNOPSIS ✨

struct iwl_system_statistics_part1_notif_oper {
    __le32 time_stamp;
    struct iwl_stats_ntfy_part1_per_link per_link[IWL_FW_MAX_LINKS];
    __le32 per_phy_crc_error_stats[IWL_STATS_MAX_PHY_OPERATIONAL];
};

look at her. three fields, zero drama, all business 💅

---

👑 Members 👑

• time_stamp — the time when the notification is sent from firmware. basically the little timestamp receipt so you know when the firmware shipped this thing off 🕐
• per_link — the per link statistics, and it's a struct iwl_stats_ntfy_part1_per_link array with IWL_FW_MAX_LINKS slots. one for each link, no cap 🦋
• per_phy_crc_error_stats — the per phy crc error statistics, sitting in a __le32 array sized IWL_STATS_MAX_PHY_OPERATIONAL. crc errors per phy, tracked and accounted for, periodt 💀

ngl, all these fields are little-endian (__le32) so don't go reading them raw on a big-endian box and then act surprised, iykyk 🙈
