STRUCT IWL_ESR_TRANS_FAIL_NOTIF(9)

💅 struct iwl_esr_trans_fail_notif(9) — Kernel API Manual

okay so bestie, welcome to the glow-up of struct iwl_esr_trans_fail_notif — it lives in the Kernel API Manual and it's literally the struct where FW (that's firmware, iykyk) slides into your feed to be like "hey girl, the EMLSR transition did NOT go as planned 😭". Yes, this is that page. Buckle up. 🦋

✨ NAME ✨

struct iwl_esr_trans_fail_notif — FW reports a failure in EMLSR transition. that's it, that's the whole vibe. it's giving "something went wrong and we're telling you about it" 💀

🌸 SYNOPSIS 🌸

struct iwl_esr_trans_fail_notif {
    __le32 link_id;
    __le32 activation;
    __le32 err_code;
 };

three __le32 fields, no notes, no extras, just vibes and little-endian integers 🎀

👑 Members 👑

• link_id — the link_id that still works after the failure. like, after all the drama, this one link is still standing and honestly? main character energy 💅
• activation — true if the link was activated, false otherwise. a simple little boolean moment, we love a clear binary 🫶
• err_code — the actual tea ☕ — see enum iwl_esr_trans_fail_code for what went down

and that's the whole page, bestie, you ate that 🍓 this energy is from ./drivers/net/wireless/intel/i... (yes the path got truncated, not my fault, the manpage said so 💀), dated October 2026, and the page itself is the one and only struct iwl_...s_fail_notif(9). periodt. ✨🧚‍♀️
