STRUCT CT_KILL_NOTIF(9)

🫶 struct ct_kill_notif(9) — from the Kernel API Manual, bestie 💅

okay so picture this: it's a kernel API manual page, it's about a struct, and it's literally the whole CT-kill entry notification situation. The struct is called struct ct_kill_notif and it's the moment where your Wi-Fi firmware is like "hey, we're about to hit CT-kill" — and this one little struct is out here representing both versions of that notification. one struct, two eras. main character energy fr fr ✨

✨ NAME ✨

struct ct_kill_notif — the CT-kill entry notification. This structure represent both versions of this notification. yes she does both. versatile icon 💖

---

🌸 SYNOPSIS 🌸

struct ct_kill_notif {
    __le16 temperature;
    u8 dts;
    u8 scheme;
 };

three fields, that's it, no cap. keep them exactly like that, bestie — don't be out here renaming things 🎀

🦋 Members 🦋

• temperature — the current temperature, in celsius. that's the vibe check on how hot we're running 🔥
• dts — only in v2, iykyk. this is the DTS that trigger the CT Kill, as a bitmap:
  • bit 0: ToP master
  • bit 1: PA chain A master
  • bit 2: PA chain B master
  • bit 3: ToP slave
  • bit 4: PA chain A slave
  • bit 5: PA chain B slave
  • bits 6,7: reserved (set to 0) 🙈

so basically six whole bits of drama and two reserved ones minding their own business ⭐

• scheme — only for v2: the scheme that trigger the CT Kill (0-SW, 1-HW). soft or hard, pick your fighter 💅

👑 SEE ALSO 👑

the kernel file lives at ./drivers/net/wireless/intel/iwlwifi/fw/api/phy.h and it's giving very much "read me next" 🧚

and then the whole friend group shows up, all of them page-(9) girlies:

• enum iwl_phy_ops_subcmd_ids(9)
• struct iwl_dts_measurement_cmd(9)
• enum iwl_dts_control_measurement_mode(9)
• enum iwl_dts_used(9)
• enum iwl_dts_bit_mode(9)
• struct iwl_ext_dts_measurement_cmd(9)
• struct iwl_dts_measurement_notif_v1(9)
• struct iwl_dts_measurement_notif(9)
• struct iwl_dts_measurement_resp(9)
• enum iwl_ctdp_cmd_operation(9)
• struct iwl_ctdp_cmd(9)
• struct temp_report_ths_cmd(9)

periodt. go read them, they ate 🌈

ngl this struct is smol but she's doing important work. technically it's just a firmware notification payload — respect the bits and set the reserved ones to 0 like the page says, okay? 🍓

💜 that's the whole page! shoutout to the source path ./drivers/net/wireless/intel/i... and the date stamp October 2026 — that's the footer, babes, we're done here. bye bestie, slay your kernel dev journey 💖✨🎀
