STRUCT ATH11K_CHAN_POWER_INFO(9)

💅 struct ath11k_chan_power_info(9) 💅

okay so bestie, buckle up — this is a page from the Kernel API Manual and honestly it's short and sweet, so let's get into it ✨

---

🌸 NAME 🌸

struct ath11k_chan_power_info — it's the TPE holding the power info for each channel chunk. yes, that TPE. it's giving "small struct, big job" energy fr fr 🫶

---

✨ SYNOPSIS ✨

struct ath11k_chan_power_info {
    u16 chan_cfreq;
    s8 tx_power;
 };

that's it. that's the whole struct. two members. iconic minimalism honestly 👑

---

🎀 Members 🎀

• chan_cfreq — this one's the channel center freq, in MHz. and okay, the way it changes depending on how wide your channel is?? literally so extra. here's the whole rundown, no cap:
  • channel 37/20 MHz → it is 6135
  • channel 37/40 MHz → it is 6125
  • channel 37/80 MHz → it is 6145
  • channel 37/160 MHz → it is 6185

yes bestie, same channel, four different center freqs depending on the width. that's just how it is. 💀

• tx_power — the transmit power, in dBm. simple. elegant. slay. 🔥

🦋 SEE ALSO 🦋

• the Kernel file ./drivers/net/wireless/ath/ath11k/core.h
• and its bestie, struct ath11k_reg_tpc_power_info(9) — go read that one too, iykyk 💖

ngl this struct is tiny but every field matters, so don't go renaming anything or changing types. u16 and s8 are exactly what they are. periodt. 🙈

and that's the whole vibe check, bestie! 🌈 this lil page lives in ./drivers/net/wireless/ath/ath11k, and it's dated October 2026 — so mark your calendar and see you back here then 💅🎀🦋✨🍓💜
